Access to The Rapids Subdivision is via County Road 335; two access roads from the County Road into the Subdivision are proposed. These access roads are located on County Road 335 approximately 1.5 miles west of Apple Tree Mobile Home Park (see Vicinity Map). Traffic impacts on County Road 335 were analyzed west of The Rapids Subdivision, east of The Rapids Subdivision near Garfield Creek, and east of Apple Tree Park. Traffic analysis included the following: • An analysis of existing peak hour traffic • Calculation of peak hour traffic to be generated by The Rapids Subdivision • Determination of traffic capacity for County Road 335 • Analysis of sight distance at proposed roadway intersections for The Rapids Subdivision. Peak Hour Traffic calculations and Sight Distance calculations are summarized in Attachment A. EXISTING TRAFFIC Traffic count data for County Road 335 obtained from the Garfield County Road and Bridge Department is summarized in Attachment B. Hourly traffic counts were taken on County Road 335 east of Apple Tree Park on November 28 and December 12, 1990. The maximum hourly traffic counted was 175 vehicles per hour (VPH). The total daily traffic counted in November of 1990 was 1,500 vehicles per day (VPD). The maximum daily traffic counted was 2,701 vehicles in October of 1994 (during hunting season). For purposes of this analysis, the design Peak Hour Traffic was calculated based upon the maximum hourly traffic count from 1990 (175 VPH) adjusted to the maximum daily traffic count from 1994 (2.701 VPD). The results of this analysis indicate a Peak Hour Traffic Count of 315 VPH (175 x 2701/1500) for existing traffic on County Road 335 east of Apple Tree Park. Similar calculations indicate a Peak Hour Traffic Count of 96 VPH on County Road 335 at Garfield Creek Road and 55 VPH on County Road 335 at East Divide Creek Road (west of The Rapids). Calculations for existing Peak Hour Traffic are summarized in Attachment A. GENERATED TRAFFIC Peak hour traffic generated by The Rapids Subdivision was calculated based upon the Institute of Transportation Engineers Trip Generation Manual (Attachment C). Calculations indicate a peak hour traffic count of 40 vehicles per hour (VPH) generated by the 40 -lot subdivision. It was assumed that 70 percent of the traffic would travel east on County Road 335 and that 30 percent of the traffic would travel west on County Road 335. ROADWAY CAPACITY The traffic capacity of County Road 335 was determined using the methodology outlined in the Highway Capacity Manual for rural, two-lane highways (Attachment D). Capacity analysis worksheets for County Road 335 east of Apple Tree Park, for County Road 335 near Garfield Creek Road and for County Road 335 west of The Rapids Subdivision are in Attachment E. The method for calculating roadway capacity includes the following parameters: • Width of Roadway • Effects of Narrow Lanes • Effects of Restricted Shoulder Width • Type of Terrain • Directional Distribution of Traffic • Roadway Grade • Roadway Curves (no passing zones) • Roadway Intersections (no passing zones) • Truck. Bus and RV Traffic A field investigation of County Road 335 from the New Castle Bridge to the Silt Bridge was conducted to determine the roadway capacity parameters for each of the three analyzed roadway segments. The "worst-case" conditions for each roadway segment were used in the analysis as outlined below: • The narrow^ ,t section of roadway, including the paved lanes and unpaved shoulders, was used in the analysis. • "Mountainous Terrain" was assumed. • The maximum amount of "curviness" for the roadway was assumed for the analysis. The results of the County Road 335 capacity analysis indicate roadway capacities of 1,300 VPH east of Apple Tree Park, 1,000 VPH near Garfield Creek, and 1,000 VPH west of The Rapids Subdivision. INTERSECTION SIGHT DISTANCE Sight distances along County Road 335 were analyzed at the two proposed intersections of Whitewater Drive and Sunset Drive with County Road 335. Sight distances were analyzed from a vehicle leaving the Subdivision onto County Road 335, and from a vehicle on County Road 335 toward a vehicle leaving the subdivision. Sight distance calculations were based upon the Colorado Department of Transportation Highway Access Code Design Standards (Attachment F). The results of the calculations are summarized in Attachment F. There is sufficient sight distance available to and from County Road 335 at both of the proposed intersections. However. at the Whitewater Drive (East) access, sight distance is limited to 350 feet west of this intersection. This is sufficient for traffic speeds of 35 mph on County Road 335. While the posted speed limit is 25 mph, it is recommended that the existing slope on the south side of County Road 335 be laid back to increase the sight distance at this location to provide an additional margin of safety. SUMMARY AND CONCLUSIONS The results of the Peak Hour Traffic Analysis including traffic from The Rapids Subdivision are summarized below: SUMMARY OF PEAK HOUR TRAFFIC ANALYSIS CO. RD. 335 EAST OF APPLE TREE PARK 31,5 VPH Existing Peak Hour Traffic 28 VPH Traffic Generated by The Rapids 343 VPH Future Peak Hour Traffic 1,300 VPH Capacity CO. RD. 335 NEAR GARFIELD CREEK 96 VPH Existing Peak Hour Traffic 28 VPH Traffic Generated by The Rapids 124 VPH Future Peak Hour Traffic 1,000 VPH Capacity CO. RD. 335 WEST OF THE RAPIDS 55 VPH Existing Peak Hour Traffic 12 VPH Traffic Generated by The Rapids 67 VPH Future Peak Hour Traffic 1,000 VPH Capacity This analysis indicates that County Road 335 has sufficient capacity for future peak hour traffic. including traffic generated by The Rapids Subdivision. The critical roadway segment for County Road 335 in terms of traffic capacity is located at and immediately east of the entrance into Apple Tree Park. Existing peak hour traffic is 24% of the roadway capacity at this location. Future peak hour traffic (i.e., including traffic from The Rapids Subdivision) will be 26% of the roadway capacity at this location. • 42- MAY -20-96 MON 10:10 AM SHELTON DRILLING CO FAX NO. 9709273801 WELL CONSTRUCTION AND TEST REPORT STATE OF COLORADO.

Chief July 10, 1996 To Whom It May Concern: RE: The Rapids on the Colorado Subdivision After reviewing the utility plan, there are two changes that should be made. Both concern the fire - hydrants in the culdesacs. The hydrant in the East culdesac should be moved out to the corner between lots 16 & 17. The hydrant in the West culdesac should be moved out to between lots 4 & 5. The reason for this is that if there is a fire in a culdesac we would like to pick up the hydrant before we reach the fire. All mains and other hydrants are within requirements. Water flow and pressures are all right as designed. Thank you, Donald L. Zordel, Chief Burning Mtns., FPD 4. Provide an analysis of agricultural impacts. There will be no significant impacts on other agricultural properties because The Rapids property is isolated by natural, physical barriers; the Colorado River to the north and west. Garfield Creek to the east. and the high, steep slope across County Road 335 to the south. In addition, most of the properties in the vicinity of The Rapids are non-agricultural. Of the 19 adjacent property owners within 200 feet of The Rapids (listed in Section VIII of the Preliminary Plan submittal), only 2 properties are primarily agricultural. Most of the adjacent properties are 2-4 acre residential or commercial parcels. The only negative potential impact on agricultural properties would be conflicts with agricultural vehicles on County Road 335. The amount of traffic generated by The Rapids development is discussed in the Traffic Impact Analysis. Impacts due to stray dogs from the development is not considered to be a potential problem due to the physical separation of the development from agricultural properties and due to the strict dog control requirements in the Protective Covenants. Tl r nrimar_y_impact on agricultural properties will be due to the reduction in. irrigation diversions from the Moore Ditch. which has been used historically to irrigate The Rapids property. The Moore Ditch is a senior irrigation water right on Garfield Creek. which is an over -appropriated stream. A reduction in diversions from the Moore Ditch as a result of The Rapids development will make additional water available for other irrigation ditches that divert from Garfield Creek. Some of this water must be bypassed to augment water use from the wells. but only the consumptive use portion of the water must be augmented and only when there is a water right call on the Colorado River. The net result is a significant amount of additional water (up to 1.5 cfs) available for diversion from Garfield Creek during the irrigation season. ! • �ExHIB1T, Page 1 of 3 LEGAL DESCRIPTION Encumbered Property Covering Land in the State of Colorado, County of Garfield Described as: Township 6 South, Range 91 West of the 6th Principal Meridian Section 12: S1/2SE1/4 Section 13: W1/2E1/2, E1/2SW1/4 Section 15: SW1/4SW1/4 Section 16: SE1/4SE1/4, N1/2SE1/4, NE1/4 Section 21: E1/2NE1/4 Section 22: W1/2, NE1/4 Section 23: NE1/4SE1/4, SE1/4SE1/4, NE1/4NE1/4, S1/2NW1/4, S1/2SW1/4, NE1/4SW1/4 Section 24: W1/2NE1/4, W1/2 Section 25: W1/2SE1/4, NE1/4SE1/4, SW1/4, E1/2NW1/4, SW1/4NW1/4 Section 26: S1/2 and NE1/4 Section 27: SE1/4, W1/2NE1/4, N1/2SW1/4, E1/2NW1/4 and SW1/4NW1/4 Section 28: S1/2NE1/4 and N1/2SE1/4 Section 34: NW1/4NE1/4 Section.35: N1/2N1/2 Section 36: S1/2NW1/4, N1/2SW1/4, NW1/4NW1/4, SE1/4SW1/4 SW1/4SS1/4, NE1/4NW1/4, NW1/4NE1/4 Township 7 South, Range 91 West of the 6th Principal Meridian Section 1: SW1/4SE1/4, Lot 2 and Lot 3 Section 12: S1/2NE1/4, NW1/4NE1/4 Township 6 South, Range 91 West of the 6th Principal Meridian Section 9: SW1/4SE1/4, SW1/4NE1/4, NE1/4SW1/4, E1/2NW1/4 All that part of the Following lands lying South of the County Road running Westerly down the South side of the Grand (now Colorado).

Consulting Engineers and Hydrologists August 6, 1996 Mr. Eric McCafferty Garfield County Planning Department 109 Eighth Street, Suite 303 Glenwood Springs, CO 81601 RE: The Rapids on the Colorado Dear Eric: AAR\ r AUG 0 b 1996 J tt. TY This letter outlines the additional information and analysis that you recommended that the Applicant provide for the Planning Commission's review of The Rapids on the Colorado Subdivision. Your previous Staff Report to the Planning Commission concluded with the following recommendation: RECOMMENDATION Based on the above analysis, staff recommends CONTINUANCE of the application to allow time for the applicant to demonstrate that the seasonal ground water level and other site or soil characteristics will not be a hinderance to effective use of ISD systems, to provide an analysis of expected traffic, school and agricultural impacts, monitor the water levels in the wells intended for use as community water supply, designate easements for the water supply tank, demonstrate the access to the water tank would be less than 14% grade, designate the high water mark of the Colorado River and Garfield Creek, receive specific approval of the fire protection plan from the Burning Mountains Fire Protection District and, if not done so, demonstrate that no illegal subdivision will occur as a result of approval of this request. If the Planning Commission feels that these issues have been addressed in an adequate manner, then staff recommends approval, subject to the following conditions. These issues are addressed below. 1. Demonstrate that the seasonal ground water level and other site or soil characteristics will not be a hinderance to effective use of individual sewage disposal system. Additional soil profile pits have been excavated and soil percolation tests have been conducted adjacent to the Colorado River to further evaluate soil characteristics and depth to groundwater. This information will be provided in a separate report. 302 Eighth Street, Suite 325 P.O. Drawer 160 Glenwood Springs. Colorado 81602 (970) 945-2236 Fax (970) 945-2977 Mr. Eric McCafferty Page - 2 2. Provide an analysis of expected traffic impacts. Refer to the Traffic Impact Analysis dated 7/30/96. 3. Provide an analysis of school impacts. A letter was sent to the School District on July 12th to request their comments. I discussed the proposed development with Leonard Eckhart, the School District Superintendent, on July 31st. Mr. Eckhart indicated that he would like Garfield County to require residential developments to dedicate land or cash in lieu of land for future school sites. Mr. Eckhart did not provide any comments specifically related to The Rapids subdivision. 4. Provide an analysis of agricultural impacts. There will be no significant impacts on other agricultural properties because The Rapids property is isolated by natural, physical barriers; the Colorado River to the north and west, Garfield Creek to the east, and the high, steep slope across County Road 335 to the south. In addition, most of the properties in the vicinity of The Rapids are non-agricultural. Of the 19 adjacent property owners within 200 feet of The Rapids (listed in Section VIII of the Preliminary Plan submittal), only 2 properties are primarily agricultural. Most of the adjacent properties are 2-4 acre residential or commercial parcels. The only negative potential impact on agricultural properties would be conflicts with agricultural vehicles on County Road 335. The amount of traffic generated by The Rapids development is discussed in the Traffic Impact Analysis. Impacts due to stray dogs from the development is not considered to be a potential problem due to the physical separation of the development from agricultural properties and due to the strict dog control requirements in the Protective Covenants. The primary impact on agricultural properties will be due to the reduction in irrigation diversions from the Moore Ditch, which has been used historically to irrigate The Rapids property. The Moore Ditch is a senior irrigation water right on Garfield Creek, which is an over -appropriated stream. A reduction in diversions from the Moore Ditch as a result of The Rapids development will make additional water available for other irrigation ditches that divert from Garfield Creek. Some of this water must be bypassed to augment water use from the wells, but only the consumptive use portion of the water must be augmented and only when there is a water right call on the Colorado Mr. Eric McCafferty Page - 3 River. The net result is a significant amount of additional water (up to 1.5 cfs) available for diversion from Garfield Creek during the irrigation season. 5. Monitor water levels in the wells intended for use as community water supply. The water levels in the two wells were measured again on July 23rd; the change (rise) in water levels from the dates that the wells were test pumped is summarized below: Well No. 1 Static Water Level: Well No. 2 Static Water Level: 15'-8" deep on 4/9/96 9'-10" deep on 7/23/96 16'-9" deep on 4/15/96 9'-7" deep on 7/23/96 6. Designate easements for the water supply tank. The easement for the water tank will be a 40 -foot radius from the center of the water storage tank. The easement for the water main will be 20 feet in width. The easement for the access roadway to the tank will be 30 feet in width. 7. Demonstrate that the access to the water tank would be less than 14% grade. The access roadway to the tank has been staked out and the approximate grade has been field surveyed. The grade of this roadway will be less than 14 percent. A detailed design drawing of the access roadway, including a roadway plan and profile grades, will be submitted with the Final Plat construction drawings. 8. Designate the high water mark of the Colorado River and Garfield Creek. The high water mark of the Colorado River and of Garfield Creek are located 30 feet from the building envelopes on Lots 1-20 as shown on the Preliminary Plan. This is the purpose of the building envelopes; to prevent construction within a 30 -foot setback from high water. 9. Receive specific approval of the fire protection plan from the Burning Mountain Fire Protection District. The proposed fire protection improvements were conditionally approved by the Fire Chief in his letter dated July 10, 1996. Mr. Eric McCafferty Page - 4 10. Demonstrate that no illegal subdivision will occur as a result of approval of this (subdivision) request. The remaining property owned by the Applicant located on the south side of County Road 335 will be "merged" with the Applicants adjacent 41 -acre property via a Lot Line Adjustment as discussed in our meeting with the County Attorney. Please forward this information to the Planning Commission for their consideration during the August 14th public hearing. If you have any questions or would like additional information, please let me know. Sincerely, ENARTECH, INC. Peter Belau, P.E. PB/jlw cc: Gene Hilton Scott Balcomb P423-01 (P423 19B)96 ENARTECH Inc. Consulting Engineers and Hydrologists August 8, 1996 Mr. Eric McCafferty Garfield County Planning Department 109 Eighth Street, Suite 303 Glenwood Springs, CO 81601 RE: The Rapids on the Colorado Subdivision Dear Eric: Enclosed is an additional report from Hepworth-Pawlak Geotechnical evaluating the feasibility of the subsoils within The Rapids on the Colorado Subdivision for use in infiltration sewage disposal systems. This evaluation includes soil profile logs to a depth of 8 feet and soil percolation tests at an additional 9 locations adjacent to the Colorado River. Groundwater was not encountered within any of the 9 test pits excavated to a depth of 8 feet. The results of the soil percolation testing indicate that the site should be suitable for conventional individual sewage disposal systems and leachfields. Also enclosed is some information from the U.S. Environmental Protection Agency (EPA) regarding the treatment and disposal of wastewater by soil absorption, along with the Colorado Health Department's standard limitations for discharges from a central wastewater treatment plant into the Colorado River. This information is summarized below for comparison of these two wastewater treatment alternatives. WASTEWATER SOIL ABSORPTION CENTRAL WASTEWATER EFFLUENT SYSTEM (THROUGH TREATMENT PLANT PARAMETER 5 FEET OF SOIL)* DISCHARGE LIMITATIONS Biochemical Oxygen Demand <2 mg/1 30 - 45 mg/1 Total Suspended Solids <1 mg/1 75 - 100 mg/1 Fecal Coliform Bacteria 0 6,000 - 12,000 per 100 ml * From U.S. EPA expected quality of treated water from land treatment processes, based up Slow Rate Process, which has a loading rate similar to a leachfield. 302 Eighth Street. Suite 325 P.O. Drawer 160 Glenwood Springs, Colorado 81602 (970) 945-2236 Fax (970) 945-2977 Mr. Eric McCafferty Page - 2 Other advantages of soil absorption systems as compared to central wastewater treatment systems include the following: 1. Potential for human contact with effluent 2. Odors 3. Airborne contaminants 4. Insects 5. Treatment system upsets 6. System failure modes (If a central wastewater plant fails, untreated sewage is usually discharged into the river. If a leachfield fails, wastewater must be pumped out of the septic tank.) 7. Cost of wastewater collection systems 8. Cost of wastewater treatment systems 9. Impacts on adjacent property owners A potential disadvantage of individual sewage disposal systems is the operation and maintenance of these systems. Since each system is owned and operated individually, the owner is responsible for the operation and maintenance of the system. If you abuse your system, it may fail and you may not be able to use it. An Operation and Management Plan for individual sewage disposal systems within The Rapids subdivision has been proposed to address this issue. The Garfield County Zoning Regulations (Section 5.04.03 of the Supplementary Lot Area Regulations) requires a minimum lot size of 1 acre for individual sewage disposal systems. The proposed lots within The Rapids subdivision are 2 acres in size. The lots located adjacent to the Colorado River (Lots 1-19) include some property within the river. The average '`dry" area of these lots is 1.31 acres; the minimum "dry" area of any lot is 1.12 acres. The Zoning Regulations also state the following regarding lot areas: If, as a result of percolation tests or other evaluations by the environmental Health Officer, the use of septic tanks or other individual sewage treatment facilities for uses and at densities as provided under the appropriate Zone District Regulations would result in a danger to health on the subject or adjacent lots, the miniinum lot areas may be increased and the number of uses permitted by right under the appropriate zone district inay be decreased and the maximum floor area ratio may be reduced by the County Commissioners. The proposed lot size of 2 acres within The Rapids is a use permitted by right. The results of the percolation tests and the other evaluations that have been provided clearly indicate that the use of individual sewage disposal systems would not result in a danger to health. Therefore. Mr. Eric McCafferty Page - 3 their is no basis for the County Commissioners to change the lot areas permitted by right within The Rapids subdivision. Please forward this information to the Planning Commission and to the Board of County Commissioners for their consideration. Sincerely, ENARTECH, INC. Peter Belau, P.E.

Dear Mr. Hilton: As requested, we conducted additional percolation testing at the subject site to evaluate the feasibility of infiltration septic disposal systems. The additional test areas were coordinated with Peter Belau, of Enartech, Inc. We previously conducted percolation on the property and presented the results in a report dated May 12, 1995. Nine percolation test holes and profile pits were excavated on the subject site at the locations shown on Figure 1. The subsoils encountered in the profile pits varied across the site and are shown graphically on Figure 1 Results of a gradation test performed on a sample of the sand are presented on Fig. 4. Seven of the percolation tests were performed in the fine sand, silt and clay soils and two of the tests were conducted in sand and gravel soils. The percolation tests were performed in hand dug holes within backhoe pits. The holes were soaked on July 31, 1996 and the tests performed on August 1, 1996. If you have any questions or if we can he of further assistance, please let us know. Sincerely, HEPWORTH-PAWLAK GEOTECHNICAL, INC. 9k,w1 Steven L. Pawlak, P.E.

Design Manual Onsite Wastewater Treatment and Disposal Systems determined largely by the physical properties of the soil. Descriptions of some of the more important physical properties appear in Appendix A. The soil is capable of treating organic materials, inorganic substances, and pathogens in wastewater by acting as a filter, exchanger, adsorber, and a surface on which many chemical and biochemical processes may occur. The combination of these processes acting on the wastewater as it passes through the soil produces a water of acceptable quality for discharge into the groundwater under the proper conditions. Physical entrapment of particulate matter in the wastewater may be responsible for much of the treatment provided by soil. This process performs best when the soil is unsaturated. If saturated soil condi- tions prevail, the wastewater flows through the larger pores and re- ceives minimal treatment. However, if the soil is kept unsaturated by restricting the wastewater flow into the soil, filtration is enhanced because the wastewater is forced to flow through the smaller pores of the soil. Because most soil particles and organic matter are negatively charged, they attract and hold positively charged wastewater components and repel those of like charge. The total charge on the surfaces of the soil sys- tem is called the cation exchange capacity, and is a good measure of the soil's ability to retain wastewater components. The charged sites in the soil are able to sorb bacteria, viruses, ammonium, nitrogen, and phosphorus, the principal wastewater constituents of concern. The retention of bacteria and viruses allows time for their die -off or destruction by other processes, such as predation by other soil micro- organisms (1)(2). Ammonium ions can be adsorbed onto clay particles. Where anaerobic conditions prevail, the ammonium ions may be retained on the particles. If oxygen is present, bacteria can quickly nitrify the ammonium to nitrate which is soluble and is easily leached to the groundwater. Phosphorus, on the other hand, is quickly chemisorbed onto mineral surfaces of the soil, and as the concentration of phosphorus increases with time, precipitates may form with the iron, aluminum, or calcium naturally present in most soils. Therefore, the movement of phosphorus through most soils is very slow (1)(2). Numerous studies have shown that 2 ft to 4 ft (0.6 to 1.2 m) of unsaturated soil is sufficient to remove bacteria and viruses to acceptable levels and nearly all phosphorus (1)(2). The needed depth is determined by the permeability of the soil. Soils with rapid permeabilities may require greater unsaturated depths below the infiltrative surface than soils with slow permeabilitiers. 14 United States Environmental Protection Agency Technology Transfer ►EPA.

Higher values expected when operating through a moderately cold winter or when using secondary effluent at high rates. 1.4 Slow Rate Process Slow rate land treatment is the application of wastewater to a vegetated land surface with the applied wastewater being treated as it flows through the plant -soil matrix. A portion of the flow percolates to the ground water and some is used by the vegetation. Offsite surface runoff of the applied water is generally avoided in design. Schematic views of the typical hydraulic pathways for SR treatment are shown in Figure 1-1(a)(b)(c). Surface application tech- niques include ridge -and -furrow and border strip flooding. Application by sprinklers can be from fixed risers or from moving systems, such as center pivots. 1.4.1 Process Objectives Slow rate processes can be operated to achieve a number of objectives including: 1. Treatment of applied wastewater 2. Economic return from use of water and nutrients to produce marketable crops (irrigation) 1-4 CHAPTER 4 SLOW RATE PROCESS DESIGN 4.1 Introduction The key elements in the design of slow rate (SR) systems are indicated in Figure 4-1. Important features are: (1) the iterative nature of the procedure, and (2) the input information that must be obtained for detailed design. Determining the design hydraulic loading rate is the most important step in process design because this parameter is used to determine the land area required for the SR system. The design hydraulic loading rate is controlled by either soil permeability or nitrogen limits for typical municipal wastewater. Crop selection is usually the first design step because preapplication treatment, hydraulic and nitrogen loading rates, and storage depend to some extent on the crop. Preapplication treatment selection usually precedes determination of hydraulic loading rate'because it can affect the wastewater nitrogen concentration and, therefore, the nitrogen loading. 4.2 Process Performance The mechanisms responsible for treatment and removal of wastewater constituents such as BOD, suspended solids (SS), nitrogen, phosphorus, trace elements, microorganisms, and trace organics are discussed briefly. Levels of removal achieved at various SR sites are included to show how removals are affected by loading rates, crop, and soil characteristics. Chapter 9 contains discussion on the health and environmental effects of these constituents. 4.2.1 BOD and Suspended Solids Removal BOD and SS are removed by filtration and bacterial action as the applied wastewater percolates through the soil. BOD and SS are normally reduced to concentrations of less than 2 mg/L and less than 1 mg/L, respectively, following 1.5 m (5 ft) of percolation. Typical loading rates of BOD and SS for municipal wastewater SR systems, regardless of the degree of preapplication treatment, are far below the loading rates at which performance is affected (see Section 2.2.1.1). Thus, loading rates for BOD and SS are normally not a concern in the design of SR systems. Removals of BOD achieved at five selected sites are presented in Table 4-1.

Lithium toxicity limit is suggested at 2.5 mg/L concentration for all crops, except citrus which uses a 0.075 mg/L limit. Soil retention is extremely limited. As noted in Table 1-3, fecal coliforms are normally absent after wastewater percolates through 1.5 m (5 ft) of soil. Coliform removals at several operating SR systems are shown in Table 4-6. Coliform removal in the soil profile is approximately the same when primary or secondary preapplication treatment is provided [4]. Virus removals are not as well documented. State agencies may require secondary treatment if edible crops are grown or if public contact is unlimited. Microorganism removal is not a limiting factor in the SR design procedure. ENARTECH Inc.

Your memo raised a number of questions that I will address in this letter. Regarding the construction of individual sewage disposal systems on Lots 1 - 19 (adjacent to the Colorado River), please find enclosed a report by Hepworth-Pawlak Geotechnical. with soil profile logs to a depth of 8 feet and soil percolation tests at 9 locations adjacent to the Colorado River. Groundwater was not encountered within any of the 9 test pits excavated to a depth of 8 feet. The results of the soil percolation testing indicate that the site should be suitable for conventional leachfields. There are no unstable river banks on the property: the slope of the river bank is gradual. Regarding the required setbacks to water courses for individual sewage disposal systems (ISDS) on Lots 1 - 19 (and on Lot 20), we have agreed with Garfield County to provide ISDS "building envelopes" on the Final Plat for Lots 1 - 20. These ISDS "building envelopes" will set tackat least feet the Colorado River and from Garfield Creek. ,A s cu know. be tack 1,..aJL 150 from the the required setback distance is 50 feet, so we intend to significantly exceed the standard requirements in this regard. Regarding the construction of ISDS in the flood fringe of the 100 -year floodplain. we have agreed with Garfield County to remove all of the proposed development out of the floodplain. including the construction of buildings and ISD systems. This will be accomplished by locating the building envelopes outside of the floodplain and/or by filling in portions of the flood fringe area to an elevation at least 1 foot above the 100 -year flood elevation to effectively remove these areas from the floodplain. 302 Eighth Street.

Colorado 81602 (970) 945-2236 Fax (970) 945-2977 Mr. Dwain Watson Page - 2 Regarding the lot sizes on Lots 1 - 19, The Garfield County Zoning Regulations require a minimum lot size of 1 acre for ISDS when water supply is from a central system. Lots 1 - 19 have a minimum lot area of 2 acres including property within the river, an average of 1.41 acres excluding the river property, and minimum lot area of .1.12 acres excluding the river property. All of these lots are of sufficient size for the installation of individual sewage disposal systems. Regarding the utilization of the existing wastewater treatment facility serving the Apple Tree Mobile Home Park, we did contact the owner of this facility to discuss the possibility of obtaining wastewater treatment service for The Rapids development. Please find enclosed a copy of their (n_Pgative) response The Rapids on The Colorado Subdivision recently obtained approval for the Garfield County Planning Commission. One of the conditions of approval was that "the Colorado Department of Public Health and Environment shall provide a favorable response to this subdivision's proposed method of waste water treatment, prior to final approval by the Board of County Commissioners". The project is scheduled for a public hearing before the Board of County Commissioners on October 7th. Please provide your response to Garfield County prior to October 7th for this meeting.

Dear Mr. Hilton: As requested, we conducted additional percolation testing at the subject site to evaluate the feasibility of infiltration septic disposal systems. Tlie additional test areas were coordinated with Peter Belau, of Enartech, inc. We previously conducted percolation on the property and presented the results in a report dated May 12, 1995. Nine percolation test holes and profile pits were excavated on the subject site at the locations shown on Figure 1. The subsoils encountered in the profile pits varied across the site and are shown graphically on Figure 2. Results of a gradation test performed on a sample of the sand are presented on Fig. 4. Seven of the percolation tests were performed in the fine sand, silt and clay soils and two of the tests were conducted in sand and gravel soils. The percolation tests were performed in hand dug holes within backhoe pits. The holes were soaked on July 31, 1996 and the tests performed on August 1, 1996. If you have any questions or if we can be of further assistance, please let us know. Sincerely, HEPWORTH-PAWLAK GEOTECHNICAL, INC. Steven L. Pawlak, P.E.

THE RAPIDS ON THE COLORADO TRAFFIC IMPACT ANALYSIS Prepared By: Enartech, Inc. 302 8th Street, Suite 325 Glenwood Springs, CO 81601 (970) 945-2236 Peter Belau, P.E. 7/30/96 INTRODUCTION The purpose of this report is to evaluate traffic impacts on Garfield County Road 335 (Colorado River Road) associated with The Rapids on the Colorado Subdivision. Access to The Rapids Subdivision is via County Road 335; two access roads from the County Road into the Subdivision are proposed. These access roads are located on County Road 335 approximately 1.5 miles west of Apple Tree Mobile Home Park (see Vicinity Map). Traffic impacts on County Road 335 were analyzed west of The Rapids Subdivision, east of The Rapids Subdivision near Garfield Creek, and east of Apple Tree Park. Traffic analysis included the following: • An analysis of existing peak hour traffic • Calculation of peak hour traffic to be generated by The Rapids Subdivision • Determination of traffic capacity for County Road 335 • Analysis of sight distance at proposed roadway intersections for The Rapids Subdivision. Peak Hour Traffic calculations and Sight Distance calculations are summarized in Attachment A. EXISTING TRAFFIC Traffic count data for County Road 335 obtained from the Garfield County Road and Bridge Department is summarized in Attachment B. Hourly traffic counts were taken on County Road 335 east of Apple Tree Park on November 28 and December 12, 1990. The maximum hourly traffic counted was 175 vehicles per hour (VPH). The total daily traffic counted in November of 1990 was 1,500 vehicles per day (VPD). The maximum daily traffic counted was 2,701 vehicles in October of 1994 (during hunting season). For purposes of this analysis, the design Peak Hour Traffic was calculated based upon the maximum hourly traffic count from 1990 (175 VPH) adjusted to the maximum daily traffic count from 1994 (2,701 VPD). The results of this analysis indicate a Peak Hour Traffic Count of 315 VPH (175 x 2701/1500) for existing traffic on County Road 335 east of Apple Tree Park. Similar calculations indicate a Peak Hour Traffic Count of 96 VPH on County Road 335 at Garfield Creek Road and 55 VPH on County Road 335 at East Divide Creek Road (west of The Rapids). Calculations for existing Peak Hour Traffic are summarized in Attachment A. GENERATED TRAFFIC Peak hour traffic generated by The Rapids Subdivision was calculated based upon the Institute of Transportation Engineers Trip Generation Manual (Attachment C). Calculations indicate a peak hour traffic count of 40 vehicles per hour (VPH) generated by the 40 -lot subdivision. It was assumed that 70 percent of the traffic would travel east on County Road 335 and that 30 percent of the traffic would travel west on County Road 335. 1 N NM r— I M N M I I— N M I= I r M M VICINITY MAP THE RAT I 5 On 27c Colorado ROADWAY CAPACITY The traffic capacity of County Road 335 was determined using the methodology outlined in the Highway Capacity Manual for rural. two-lane highways (Attachment D). Capacity analysis worksheets for County Road 335 east of Apple Tree Park, for County Road 335 near Garfield Creek Road and for County Road 335 west of The Rapids Subdivision are in Attachment E. The method for calculating roadway capacity includes the following parameters: • Width of Roadway • Effects of Narrow Lanes • Effects of Restricted Shoulder Width • Type of Terrain • Directional Distribution of Traffic • Roadway Grade • Roadway Curves (no passing zones) • Roadway Intersections (no passing zones) • Truck, Bus and RV Traffic A field investigation of County Road 335 from the New Castle Bridge to the Silt Bridge was conducted to determine the roadway capacity parameters for each of the three analyzed roadway segments. The "worst-case" conditions for each roadway segment were used in the analysis as outlined below: • The narrowest section of roadway, including the paved lanes and unpaved shoulders, was used in the analysis. • "Mountainous Terrain" was assumed. • The maximum amount of "curviness" for the roadway was assumed for the analysis. The results of the County Road 335 capacity analysis indicate roadway capacities of 1,300 VPH east of Apple Tree Park, 1,000 VPH near Garfield Creek, and 1,000 VPH west of The Rapids Subdivision. INTERSECTION SIGHT DISTANCE Sight distances along County Road 335 were analyzed at the two proposed intersections of Whitewater Drive and Sunset Drive with County Road 335. Sight distances were analyzed from a vehicle leaving the Subdivision onto County Road 335, and from a vehicle on County Road 335 toward a vehicle leaving the subdivision. Sight distance calculations were based upon the Colorado Department of Transportation Highway Access Code Design Standards (Attachment F). The results of the calculations are summarized in Attachment F. There is sufficient sight distance available to and from County Road 335 at both of the proposed intersections. However, at the Whitewater Drive (East) access, sight distance is limited to 350 feet west of this intersection. This is sufficient for traffic speeds of 35 mph on County Road 335. While the posted 2 speed limit is 25 mph, it is recommended that the existing slope on the south side of County Road 335 be laid back to increase the sight distance at this location to provide an additional margin of safety. SUMMARY AND CONCLUSIONS The results of the Peak Hour Traffic Analysis including traffic from The Rapids Subdivision are summarized below: SUMMARY OF PEAK HOUR TRAFFIC ANALYSIS CO. RD. 335 EAST OF APPLE TREE PARK 315 VPH Existing Peak Hour Traffic 28 VPH Traffic Generated by The Rapids 343 VPH Future Peak Hour Traffic 1,300 VPH Capacity CO.

RD. 335 WEST OF THE RAPIDS 55 VPH Existing Peak Hour Traffic 12 VPH Traffic Generated by The Rapids 67 VPH Future Peak Hour Traffic 1,000 VPH Capacity This analysis indicates that County Road 335 has sufficient capacity for future peak hour traffic, including traffic generated by The Rapids Subdivision. The critical roadway segment for County Road 335 in terms of traffic capacity is located at and immediately east of the entrance into Apple Tree Park. Existing peak hour traffic is 24% of the roadway capacity at this location. Future peak hour traffic (i.e., including traffic from The Rapids Subdivision) will be 26% of the roadway capacity at this location. 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 ATTACHMENT A PEAK HOUR TRAFFIC CALCULATIONS AND SIGHT DISTANCE CALCULATIONS ENARTECH, INC. 302 Eighth Street, Suite 325 P.O.

METHODOLOGY LEVELS OF SERVICE As noted previously, level -of -service criteria for two-lane high- ways address both mobility and accessibility concerns. The pri- mary measure of service quality is percent time delay. with speed and capacity utilization used as secondary measures. Level -of - service criteria are defined for peak 15 -min flow periods, and are intended for application to segments of significant length. Level -of -service criteria for general terrain segments are given in Table 8-1. For each level of service, the percent time delay is shown. Average travel speed is also shown, with values varying slightly by type of terrain. The body of the table includes max- imum values of v/c ratio for the various terrain categories and levels of service A through F. The v/c ratios shown in Table 8-1 are somewhat different from those used in other chapters. For two-lane highways, the values given represent the ratio of flow rate to "ideal capacity," where ideal capacity is 2,800 pcph for a level terrain segment with ideal geometrics and 0 percent no passing zones. Two-lane highways are quite complex, and capacities vary depending on terrain and the degree of passing restrictions. To simplify computational procedures. v/c ratios are given in terms of the constant "ideal capacity" of 2,800 pcph, total in both directions of flow. The level -of -service criteria of Table 8-1 are for extended segments of two-lane rural highways where efficient mobility is the primary objective of the facility. Where speeds have been restricted by an agency, such as through a town or village, the percentage of time delay and capacity utilization are the only meaningful indicators of level of service. 8-5 Table 8-2 gives level -of -service criteria for specific grade seg- ments. These criteria relate the average travel speed of upgrade vehicles to level of service. Operations on sustained two-lane grades are substantially different from extended segments of general terrain. The speed of upgrade vehicles is seriously im- pacted, as the formation of platoons behind slow-moving ve- hicles intensifies and passing maneuvers generally become more difficult. Further, unlike general terrain segments. where the approximate average travel speed at which capacity occurs can be identified, the capacity speed for a specific grade depends on the steepness and length of the grade and volume. Because of this, estimation of capacity is complex. Thus, Table 8-2 defines separate level -of -service criteria for specific grade segments. In addition, this chapter includes special computational procedures for sustained grades on two-lane highways. Downgrade operations are not specifically addressed by these procedures. Downgrade operations on gentle grades (less than 3 percent) are generally comparable to those on a level roadway. On more severe grades, downgrade operations are about midway between those experienced on a level roadway and those ex- perienced on an upgrade of equivalent traffic and roadway char- acteristics. The principal concern on steep downgrades is the potential for "runaway" trucks. The highest quality of traffic service occurs when motorists are able to drive at their desired speed. Without strict enforce- ment, this highest quality, representative of level -of -service A, would result in average speeds approaching 60 mph on two- lane highways. The passing frequency required to maintain these speeds has not reached a demanding level. Passing demand is TABLE 8-1.

Drivers would be delayed no more than 30 percent of the time by slow-moving vehicles. A maxi- mum flow rate of 420 pcph, total in both directions, may be achieved under ideal conditions. Level -of -service B characterizes the region of traffic flow wherein speeds of 55 mph or slightly higher are expected on level terrain. Passing demand needed to maintain desired speeds becomes significant and approximately equals the passing ca- pacity at the lower boundary of level -of -service B. Drivers are delayed up to 45 percent of the time on the average. Service flow rates of 750 pcph, total in both directions, can be achieved under ideal conditions. Above this flow rate, the number of platoons forming in the traffic stream begins to increase dra- matically.• Further increases in flow characterize level -of -service C, re- sulting in noticeable increases in platoon formation, platoon size, and frequency of passing impediment. Average speed still ex- ceeds 52 mph on level terrain, even though unrestricted passing demand exceeds passing capacity. At higher volume levels, chaining of platoons and significant reductions in passing ca- pacity begin to occur. While traffic flow is stable, it is becoming susceptible to congestion due to turning traffic and slow-moving vehicles. Percent time delays are up to 60 percent. A service flow rate of up to 1,200 pcph, total in both directions, can be accommodated under ideal conditions. Unstable traffic flow is approached as traffic flows enter level - of -service D. The two opposing traffic streams essentially begin to operate separately at higher volume levels, as passing becomes extremely difficult. Passing demand is very high, while passing capacity approaches zero. Mean platoon sizes of 5 to 10 vehicles are common, although speeds of 50 mph can still be maintained under ideal conditions. The fraction of no passing zones along the roadway section usually has little influence on passing. Turn- ing vehicles and/or roadside distractions cause major shock - waves in the traffic stream. The percentage of time motorists are delayed approaches 75 percent. Maximum service flow rates of 1,800 pcph, total in both directions, can be maintained under ideal conditions. This is the highest flow rate that can be main- tained for any length of time over an extended section of level terrain without a high probability of breakdown. Level -of -service E is defined as traffic flow conditions on two- lane highways having a percent time delay of greater than 75 percent. Under ideal conditions, speeds will drop below 50 mph. Average travel speeds on highways with less than ideal condi- tions will be slower, as low as 25 mph on sustained upgrades. Passing is virtually impossible under level -of -service E condi- tions, and platooning becomes intense when slower vehicles or other interruptions are encountered. The highest volume attainable under level -of -service E defines the capacity of the highway. Under ideal conditions, capacity is 2,800 pcph, total in both directions. For other conditions, capacity is lower. Note that the v/c ratios of Table 8-1 are not all 1.00 at capacity. This is because the ratios are relative to "ideal capacity" as discussed. Operating conditions at capacity are unstable and difficult to predict. Traffic operations are sel- dom observed near capacity on rural highways. primarily be- cause of a lack of demand. Capacity of two-lane highways is affected by the directional split of traffic. As directional split moves away from the 50/ 50 "ideal" condition, total two-way capacity is reduced, as follows: Directional Split 50/50 60/40 70/30 80/20 90/10 100/0 Total Capacity (pcph) 2,800 2,650 2,500 2,300 2,100 2,000 Ratio of Capacity to Ideal Capacity 1.00 0.94 0.89 0.83 0.75 0.71 For short lengths of two-lane road, such as tunnels or bridges, opposing traffic interactions may have only a minor effect on capacity. The capacity in each direction may approximate that of a fully loaded single lane, given appropriate adjustments for the lane width and shoulder width (5). As with other highway types, level -of -service F represents heavily congested flow with traffic demand exceeding capacity. Volumes are lower than capacity, and speeds are below capacity speed. Level -of -service E is seldom attained over extended sec- tions on level terrain as more than a transient condition; most often, perturbations in traffic flow as level E is approached cause a rapid transition to level -of -service F. OPERATIONAL ANALYSIS This section presents the methodology for operational analysis of general terrain segments and specific grades on two-lane highways. Separate procedures for general highway segments and grades are used, because the dynamics of traffic interaction on sustained two-lane grades differ from those on general terrain segments. Grades of less than 3 percent or shorter than 1/2 mile may be included in general terrain analysis. Grades both longer and steeper than these values should generally be treated as specific grades. Level, rolling, and mountainous terrain are as defined in Chapters 1 and 3. The length of grade is taken to be the tangent length of grade plus a portion of the vertical curves at the beginning and end of the grade. About one-fourth of the length of vertical curves at the beginning and end of a grade are included in the grade length. Where two grades (in the same direction) are joined by a vertical curve, one-half the length of the curve is included in each grade segment. TWO-LANE HIGHWAYS 8-7 The objective of operational analysis is generally the deter- mination of level of service for an existing or projected facility operating under existing or projected traffic demand. Opera- tional analysis may also be used to determine the capacity of a two-lane highway segment, or the service flow rate which can be accommodated at any given level of service. Use of the Peak Hour Factor As for other facility types, two-lane highway analysis is based on flow rates for a peak 15 -min period within the hour of interest, which is usually the peak hour. The criteria of Table 8-1 refer to equivalent hourly flow rates based on the peak 15 min of flow. These criteria are used to compute service flow rates, SF, which are compared to existing or projected flow rates to de- termine level of service. Thus, full -hour demand volumes must be converted to flow rates for the peak 15 min, as follows: v = V/PHF where: v = flow rate for the peak 15 min, total for both direc- tions of flow, in vph; V = full -hour volume total for both directions of flow, in vph; and PHF = peak hour factor. When criteria are compared to flow rates, the predicted op- erating characteristics are expected to prevail for the 15 -min period for which the flow rate applies. For many rural condi- tions. the analyst may wish to examine average conditions over a peak hour. Full -hour volumes. unadjusted for the PHF, are compared to criteria directly for these cases. It should be noted, however, that prediction of an average level -of -service C during a full hour may include portions of the hour operating at level D or E, while other portions operate at A or B. The decision to use flow rates or full -hour volumes in an analysis is related to whether or not peaking characteristics will cause substantial fluctuation in operating conditions within the peak hour. and whether the impact of such fluctuations will impact design and/or operational policy decisions. In general, where the peak hour factor is less than 0.85, operating conditions will vary substantially within the hour. Where the peak hour factor can be determined from local field data, this should be done. Where field data are not available, the factors tabulated in Table 8-3 may be used. These are based solely on the assumption of random flow and may be somewhat higher than those obtained from field studies. When level of service is to be determined for a given traffic volume, a value appropriate to the volume level on the subject segment is selected from the upper portion of the table. When a service flow rate is to be computed, a value is selected from the lower portion of the table. because volume is unknown. Analysis of General Terrain Segments The general terrain methodology estimates average traffic operational measures along a section of highway based on av- erage terrain. geometric, and traffic conditions. Terrain is class- ified as level. rolling, or mountainous, as described previously. The general terrain procedure is usually applied to highway sections of at least 2 miles in length. Highway geometric features include a general description of longitudinal section characteristics and specific roadway cross- section information. Longitudinal section characteristics are de- scribed by the average percent of the highway having no passing zones. The average for both directions is used. The percentage of roadway along which sight distance is less than 1,500 ft may be used as a surrogate for no passing zone data. Roadway cross- section data include lane width and usable shoulder width. Geo- metric data on design speed and specific grades are not used directly, but are reflected in the other geometric factors dis- cussed. TABLE 8-3.

Peak hour factors may be computed from field data, or appropriate default values may be selected from Table 8-3. Traffic data also include the proportion of trucks, recreational vehicles (RV's), and buses in the traffic stream. When estimates of the traffic mix are not available, the following default values for these fractions may be used for primary routes: . PT = 0.14 (trucks) • PR = 0.04 (RV's) . PB = 0.00 (buses) Recreational routes would typically have a higher proportion of recreational vehicles than shown for primary rural routes. 1. General relationship—The general relationship describing traffic operations on general terrain segments is as follows: SF; = 2,800 X (v/c); X fa X f. X JHS (8-1) where: SF, = total service flow rate in both directions for prevailing roadway and traffic conditions, for level of service i, in vph; (v/c), = ratio of flow rate to ideal capacity for level of service i, obtained from Table 8-1; adjustment factor for directional distribution of traffic, obtained from Table 8-4; adjustment factor for narrow lanes and restricted shoulder width, obtained from Table 8-5; adjustment factor for the presence of heavy vehicles in the traffic stream, computed as: 1/[1 + PT(ET — 1) + PR(ER — 1) + Pg (E8 — 1)] (8-2) fd = f,0 = where: PT = proportion of trucks in the traffic stream. expressed as a decimal; proportion of RV's in the traffic stream. expressed as a decimal; PR = proportion of buses in the traffic stream. expressed as a decimal; passenger -car equivalent for trucks, obtained from Table 8-6; ER = passenger -car equivalent for RV's, obtained from Table 8-6; and EB = passenger -car equivalent for buses. obtained from Table 8-6. PR = ET = Equation 8-1 takes an ideal capacity of 2,800 pcph. and adjusts it to reflect a v/c ratio appropriate for the desired level of service, directional distributions other than 50/50, lane width restric- tions and narrow shoulders, and heavy vehicles in the traffic stream. 2. Adjustment for v/c ratio—The v/c ratios given in Table 8-1 reflect a complex relationship among speed. flow. delay, and geometric parameters for two-lane highways. Specifically, v/c values vary with level -of -service criteria, terrain type. and the magnitude of passing restrictions. Note that v/c ratios at ca- pacity are not equal to 1.00 for rolling or mountainous terrain. This is because the ratios are based on an ideal capacity of 2,800 pcph which cannot be achieved on severe terrains. Further, as the formation of platoons is more frequent where terrain is rolling or mountainous, passing restrictions have a greater effect on capacity and service flow rate than on level terrain. 3. Adjustment for directional distribution—All of the v/c values in Table 8-1 are for a 50/50 directional distribution of traffic on a two-lane highway. For other directional distribu- tions, the factors shown in Table 8-4 must be applied to Table 8-1 values. 4. Adjustment for narrow lanes and restricted shoulder width—Narrow lanes force motorists to drive closer to vehicles in the opposing lane than they would normally desire. Restricted or narrow shoulders have much the same effect, as drivers "shy" away from roadside objects or point restrictions perceived to be close enough to the roadway to pose a hazard. Motorists com- pensate for driving closer to opposing vehicles by slowing down and/or by leaving larger headways between vehicles in the same lane. Both reactions result in lower flow rates being sustained at any given speed. Factors reflecting this behavior are shown in Table 8-5, and are applied to v/c values taken from Table 8-1. Factors at capacity are higher than those for other levels of service, as the impact of narrow lanes and restricted shoulder widths is less deleterious when vehicles are already traveling at reduced speeds which prevail under capacity operation. 5. Adjustment for heavy vehicles in the traffic stream—The v/c ratios of Table 8-1 are based on a traffic stream consisting of only passenger cars. All vehicles having only four wheels contacting the pavement may be considered to be passenger cars. This includes Light vans and pick-up trucks. "Heavy vehicles" are categorized as trucks, recreational ve- hicles, or buses, and the traffic stream is characterized by the proportion of such vehicles in the traffic mix. The adjustment factor for heavy vehicles, f,,., is computed using Eq. 8-2 and the passenger -car equivalents given in Table 8-6. A wide range in the proportions of trucks and RV's in the traffic stream are found on rural highways. Equation 8-2 will yield an adjustment factor for any given mix. In addition, there is some variation in the weight distribution between heavy (> 35,000 Ib) and medium -duty (< 35,000 lb) trucks. The equiv- alents of Table 8-6 assume a 50/50 distribution between heavy and medium -duty trucks. Two-lane highways serving unusually high proportions of heavy trucks, such as in coal, gravel, or timber operations, particularly those in mountainous terrain, would have higher values of ET than those shown in the table. The deleterious impact of heavy vehicles on two-lane high- ways increases markedly as terrain becomes more severe. As heavy vehicles slow on steeper grades, platoon formation be- comes more frequent and severe. This effect is compounded by passing sight distance restrictions often accompanying severe terrain and leads to serious deterioration of traffic flow. Analysis of Specific Grades The analysis of extended specific grades on two-lane highways is more complex than for general terrain segments. The analysis procedures assume that the approach to the grade is level. On such grades, the operation of upgrade vehicles is substantially 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 TWO-LANE HIGHWAYS TABLE 8-4.

As a result, level -of -service criteria presented in Table 8-2 are based on the average upgrade travel speed. This speed is the average speed of all vehicles traveling up the grade. Where composite grades are present, the average grade is used in analysis. The average grade is the total rise. in feet, of the composite grade divided by the horizontal length of the grade. in feet. multiplied by 100 to adjust from a decimal to a percentage. The average upgrade speed at which capacity occurs varies between 25 and 40 mph, depending upon the percent grade. the percentage of no passing zones, and other factors. Because op- erating conditions at capacity vary for each grade, the finding of capacity is not as straightforward as service flow rate com- putations for levels -of -service A through D, where speed is established using the criteria of Table 8-2. Research has found that grades on two-lane highways have a more significant impact on operations than similar grades on multilane highways. Platoons forming behind slow-moving ve- hicles can be broken up or dissipated only by passing maneuvers using the opposing lane. On two-lane highways, the same geo- metric features causing platoons to form also tend to restrict passing opportunities as well. It has also been found that most passenger cars, even in the absence of heavy vehicles. are affected by extended grades. and will operate less efficiently than on level terrain. Additional operational problems due to vehicle stalls, accidents, or other incidents are not accounted for in the procedure. The effects of rain, snow, ice, and other negative environmental factors are also not considered. 1. Relationship between speed and service flow rate on specific grades -Average upgrade speeds on two-lane highways may be estimated for specific grades of a given percent and length of grade. assuming a level approach to the grade. Two-way service flow rates, SF, may be calculated for a specific level of service, or correspondingly, for any designated average upgrade speed. The need to provide a climbing lane based on AASHTO's safety warrant is not part of the procedure, but sample calculation 5 illustrates the evaluation of a potential climbing lane. TABLE 8-6.

JHi This relationship for specific grades is generally not applied to grades of less than 3 percent or shorter than 1/2 mile. 2. Adjustment for v/c ratio -Table 8-7 shows values of v/c ratio related to percent grade, average upgrade speed. and per- cent no passing zones. The values shown are the ratio of flow rate to an ideal capacity of 2.800 pcph, and assume that pas- senger cars are unaffected by extended grades. Another adjust- ment is applied to account for the impacts of grades on passenger -car operation. This is an important point. because a v/c ratio of 1.00 in Table 8-7 DOES NOT necessarily signify capacity. The solution for capacity of an extended grade is discussed later. However, solutions for capacity or service flow rate exceeding 2.000 vph total indicates that the specific grade is not affecting operations and that the general terrain meth- odology should be used. Values of v/c approaching or equal to 0.00 mean that the associated average upgrade speed is difficult or impossible to achieve for the percent grade and percent no passing zones indicated. 3. Adjustment for directional distribution -On extended grades, the directional distribution can be a critical factor af- fecting operations.

Adjustment for narrok lanes and/or restricted shoulder width—The impact of narrow lanes and/or restricted shoulder widths on grades is the same as for general terrain segments. The appropriate factor is selected from Table 8-5, presented previously. 5. Adjustment for passenger cars on grades—The v/c ratios of Table 8 assume that passenger cars will maintain their speed on grades if unimpeded. Recent studies (1,2) have indicated that passenger -car operation is affected by grades. even where heavy vehicles are not present in the traffic stream. The factorf, adjusts the v/c ratios of Table 8-7 to account for this effect. The factor is computed as: where: �8 PP = fg= 111 + (PI)j (8-4) adjustment factor for the operation of passenger cars on trades; proportion of passenger cars in the upgrade traffic stream. expressed as a decimal; Ir = impedance factor for passenger cars, computed as: IP = 0.02 (E — E,) (8-5) E = base passenger -car equivalent for a given percent grade. length of grade, and speed, selected from Table 8-9: and E, = base passenger -car equivalent for 0 percent grade and a given speed, selected from Table 8-9. The passenger -car equivalents of Table 8-9 are used for both the passenger -car and heavy vehicle adjustment factors. The passenger -car factor adjusts from the base v/c ratios, which assume no operational impact of grades on cars, to prevailing conditions of grade. The heavy vehicle adjustment factor is based on passenger -car equivalents related to passenger cars operating on the grade specified. 6. Adjustment for heavy vehicles in the traffic stream—The adjustment factor for heavy vehicles is computed as follows: JHS = 1/(1 - PH, (EN,. -1)] where: (8-6) fH, = adjustment factor for the presence of heavy vehicles in the upgrade traffic stream; P7/HI total proportion of heavy vehicles (trucks - RV's — buses) in the upgrade traffic stream; passenger -car equivalent for specific mix of heavy vehicles present in the upgrade traffic stream, com- puted as: EH, = I + (0.25 -- PT/H)) (E — 1) (8-7) proportion of trucks among heavy vehicles. i.e., the proportion of trucks in the traffic stream divided by the total proportion of heavy vehicles in the traffic stream; and E = base passenger -car equivalent for a given percent grade, length of grade, and speed, selected from Table 8-9. The passenger -car equivalents presented in Table 8-9 repre- sent an average mix of trucks. recreational vehicles, and buses in the traffic stream. This average mix is for 14 percent trucks, 4 percent RV's. and no buses. The values of EH,, computed by this procedure yield equivalent volumes which travel at the same average overall speed as the actual mixed traffic stream under stable flow conditions. Any tendency of vehicles to stall or perform sluggishly at high volume levels and power require- ments is not accounted for in these procedures. The existence of heavy vehicles on two-lane highway grades is a particularly difficult problem. because an increase in for- mation of platoons is caused at the same time as passing re- strictions usually also increase. Thus, the decision of whether to provide a climbing lane for heavy vehicles is often a critical one for extended grades on two-lane highways. A common criterion sometimes used in the design of grades is to include a climbing lane where the operating speed of trucks falls 10 mph or more (11). Figures 8-2 and 8-3 show speed reduction curves for a 200 -lb /hp truck and a 300-lb/hp truck. The former is considered indicative of a representative truck for the average mix of trucks occurring on two-lane highways. The latter is representative of a "heavy" truck, such as heavily loaded farm vehicles, coal carriers, gravel carriers. or log carriers. The choice of which type of truck should be used is based on safety con- siderations. Speed reduction is related to the steepness and length of the grade in Figures 8-2 and 8-3. For a more detailed depiction of the operating characteristics of trucks on extended upgrades, the truck performance curves included in Appendix I of Chapter 3 may be consulted. In addition to the 10 -mph speed reduction criterion. a climb- ing lane might be considered wherever a level -of -service analysis indicates a serious deterioration in operating quality on an ex- tended grade when compared to the adjacent approach segment of the same highway. Heavy vehicles in the traffic stream on extended grades also cause. delay to other vehicles. Delay can be evaluated as the difference in travel time between what vehicles could achieve if unimpeded by heavy vehicles and the travel time actually ex- perienced in the mixed traffic stream. Sample calculations il- lustrate the computation of this delay. 7. Capacity of specific grade segments—Sections 1 through 6 above describe the computation of service flow rates on specific two-lane highway grades.

The service flow rate at capacity, i.e., SFE, is not as easily determined, because the speed at which it occurs varies de- pending on the percent and length of the grade in question. For the normal range of grades, i.e., 3 to 7 percent up to 4 miles long, capacity may occur at speeds ranging from 25 to 40 mph. The speed at which capacity occurs is related to the flow rate at capacity by the following equation: S, = 25 + 3.75(v,/ 1000)2 (8-8) where: S, = speed at which capacity occurs, in mph: and v, = flow rate at capacity, in mixed vph. For convenience, the equation predicts upgrade speeds based on total two-way flow rates. The equation is valid for speed up to 40 mph. If the service flow rates computed for various speeds using Eq. 8-3 and the capacity speed vs. capacity flow rate relationship of Eq. 8-8 are plotted, the two curves will intersect.

HIGHWAY SYSTEM PLANNING The planning procedure enables highway operating agencies to perform very general planning and policy studies of a rural two-lane highway system. Traffic, geometric, and terrain data would be only generally classified, with traffic demand expressed in terms of an average annual daily traffic (AADT), perhaps of some future forecast year. Table 8-10 presents estimated maximum AADT's for two- lane highways as related to: 1. Level of service. 2. Type of terrain. 3. Design hour factor, K. The levels of service refer to operating conditions within the peak 15 -min period of the day. In constructing Table 8-10, the default values of the peak hour factor (PHF) shown in Table 8-3 were assumed. For each level of service, the related percent time delay criteria were applied across all three types of terrain. The planning criteria also assume a typical traffic mix of 14 percent trucks. 4 percent RV's, and no buses. A 60/40 direc- tional split is used, along with percent no passing zone values of 20 percent. 40 percent, and 60 percent for level, rolling, and mountainous terrain, respectively. Ideal geometrics of 12 -ft lanes, 6 -ft shoulders, and 60 -mph design speed were used. 8-13 9 8 7 e 6 0 0 5 tr 4 3 2 SPEED REDUCTION BELOW AVERAGE RUNNING SPEED OF ALL TRAFFIC (mph) 20 15 10 INITIAL SPEED= 55mp 1 1 1 0 500 1000 1500 2000 LENGTH OF GRADE (ft.) Figure 8-3. Speed reduction curve for a 300-1b/hp truck The AADT's presented in Table 8-10 illustrate a wide range of conditions. and were computed from service flow rates as follows: where: AADT, _ SF = PHF = K= AADT, = SF, X PHF/K (8-9) the maximum AADT for level -of -service i, based on the assumed conditions described above; vpd; maximum service flow rate for level -of -service i, computed from Eq. 8-3, based on the assumed con- ditions described above, in vph; peak hour factor, selected from Table 8-3 for the indicated level of service; and design hour factor, i.e., the proportion of AADT expected to occur in the design hour. The K -factor is normally expressed in design problems as DHV = AADT X K, where the DHV is the total two-way design hour volume, and K is estimated from the ratio of the 30th HV to the AADT from a similar site. The 30th HV is the 30th highest hourly volume during the year and is often used as a design volume for rural highways. Since the DHV should be less than SF, for the selected level of service, the actual AADT for a road should be less than the maximum value shown in Table 8-10. Traffic conditions occurring during the highest hourly volume of the year (1st HV) would usually be no worse than one level of service less than that existing for the 30th HV for most rural highways. 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 8-14 TABLE S-10.

PROCEDURES FOR APPLICATION The methodology described in the previous section is generally applied in either the operational analysis or planning modes. Design computations, as used in this manual, focus on the determination of the number of lanes required for a given facility. Such computations have little significance for two-lane high- ways, where the number of lanes is fixed. Such design features as horizontal and vertical alignment, however, have a significant impact on operations. Operational analyses can be performed for alternative designs to document this impact. Where com- putations indicate that a two-lane highway is not adequate for existing or projected demands, various multilane options may be considered and analyzed using other chapters of this manual. A separate section of this chapter deals with operational and design measures for two-lane highways, short of reconstructing the entire highway as a multilane facility. This material should be consulted where a two-lane facility presently has or is ex- pected to experience operational difficulties. OPERATIONAL ANALYSIS OF GENERAL TERRAIN SEGMENTS The objective in operational analysis is to determine the level of service for a given segment or segments of roadway for a known existing set of conditions, or for a future set of conditions which are hypothesized and/or forecast. The general approach will be to compute service flow rates for each level of service and compare these values with the existing flow rate on the facility. This is done using Eq. 8-1: SF, = 2,800 X (v/c), Xf x Xf„, where all terms are as previously defined. A service flow rate for each LOS is computed because the heavy vehicle factor varies with LOS, and a direct solution of the equation for v/c ratio would be iterative. Users preferring to solve for v/c may do so, but must iterate until the assumed LOS used in computing the heavy vehicle factor is the same as that indicated by the v/c ratio found. In general, the following computational steps are used. Com- putations may be conveniently performed on the worksheet il- lustrated in Figure 8-4. 1.

Expansion to a multilane facility should be examined using the methodology presented in Chapter 7. OPERATIONAL ANALYSIS OF SPECIFIC GRADES The operational analysis of specific grades is similar to the procedure for general terrain segments. The level of service for the upgrade direction is sought, and is found by comparing an actual two-way flow rate to the service flow rates for the various levels of service. As noted in the "Methodology” section, how- ever, the determination of capacity for specific grades requires the plotting of a service flow rate -speed curve, and a curve representing the relationship of speed at capacity to flow rate at capacity. The worksheet shown in Figure 8-5 is used to simplify the following computational steps. 1. Summarize all required input data on traffic and roadway conditions, including: .

As with general terrain segments, a two-lane highway grade displaying unacceptable operating conditions would be consid- ered for improvement. If heavy vehicles on the upgrade are the principal difficulty, the addition of a truck climbing lane should be considered. If operational problems are more broad-based, any of the alleviation techniques discussed in the next section could be considered, as well as expansion of the facility to four or more lanes. Again, the multilane option would be examined using procedures in Chapter 7. PLANNING The highway system planning technique described in the "Methodology" section is easily applied. Table 8-10 may be entered with a known or forecast AADT to determine expected level of service during the peak 15 min of flow, or with a known LOS to find the maximum allowable AADT. No computations are needed to use this table, although users are cautioned that any conditions varying widely from those noted in the footnotes to Table 8-10 will indicate the need to conduct an operational analysis for the facility in question. Users may also find Table 8-10 useful in making preliminary estimates of LOS in general terrain segment analysis. IV. DESIGN AND OPERATIONAL TREATMENTS Addressing those operational problems that may exist on rural two-lane highways requires an understanding of the nature of two-lane highway systems. Only about 30 percent of all travel in the United States occurs on rural two-lane roads, even though this network comprises 80 percent of all paved rural highways. For the most part, two-lane highways carry light traffic and experience few operational problems. Highway agencies are typ- ically more concerned with pavement maintenance and roadside safety issues on such highways. Some two-lane highways, however, periodically experience severe operational and safety problems due to a variety of traffic, geometric, and environmental causes. Special treatments for such highways may be needed before capacity levels are ap- proached. In some areas, the two-lane rural arterial system carries a disproportionately large share of rural traffic, including significant components involved in interstate commerce. Many of these highways are located near major urban areas and are experiencing rapid growth in traffic. Heavy turning movements to roadside developments can block through traffic and increase delay. 8-18 RURAL HIGHWAYS As much as 60 percent of all two-lane highway mileage is located in terrain classified as rolling or mountainous. This. coupled with occasionally high opposing volumes. is not favor- able to either passing or turning maneuvers. When these and other rural highways experience increased recreational travel. major operational problems may arise. Large numbers of rec- reational and other heavy vehicles in the traffic stream increase the demand for passing, while at the same time, making such maneuvers more difficult. Two-lane highways serving as major routes to recreational areas may operate at or near capacity on weekends in peak seasons. When any of the foregoing situations exist. the frequent result is a reduced level of service. increased platooning, increased delay, an increase in questionable passing maneuvers, and gen- erally frustrated drivers. Nevertheless, many such situations do not justify the reconstruction of the two-lane highway to a full multilane facility. In these cases, one or more of the special design and/or operational treatments discussed in this section may be useful. A wide range of design and operational solutions are needed to address the variety of problems encountered on two-lane highways. The operational and/or safety problems on a partic- ular section may be so severe as to call for an expansion of the facility to four or more lanes. However, limited reconstruction funds, difficult terrain, and other problems may not always permit full reconstruction of a two-lane facility as a multilane highway. Less costly and less environmentally disruptive solu- tions may be required. Highways experiencing less severe op- erational and/or safety problems, together with those experiencing site-specific reductions in level of service, may be candidates for treatment with one or more of the following alleviation techniques: 1. Realignment to improve passing sight distance. 2. Use of paved shoulders. 3. Three -lane roadways with two lanes designated for travel in one direction (passing prohibited or permitted in opposing direction). 4. Three -lane road sections with continuous two-way median left -turn lanes. 5. Three -lane roadway with reversible center lane. 6. Special intersection treatments. 7. Truck or heavy vehicle climbing lanes. 8. Turnouts. 9. Short four -lane segments. Selection of the appropriate treatment requires identification of the probable causes of the operational and safety problems existing, and the determination of cost-effectiveness of the design alternatives for a given set of highway geometric, traffic, and system constraints. The following discussions address the use of alleviation measures on two-lane highways. They are intended to provide the user with general information, and should not be construed as firm guidelines or criteria. PASSING SIGHT DISTANCE The opportunity to pass, given a constant volume, is a function of the availability of passing sight distance. Provision of passing sight distance is an important component in basic two-lane highway design and, as illustrated by Tables 8-1 and 8-7, has a critical impact on capacity and service flow rate. Where long queues are likely to form because of severe passing restrictions, every effort should be made to continuously and completely disperse the platoon once significant passing sight distance is regained. In these passing sections, short segments with passing sight distance restrictions should be avoided where possible. Inclusion of periodic passing lanes for each direction should be considered where the distance between segments with passing sight distance available is long and queuing extensive. PAVED SHOULDERS A roadway that is constructed with structurally adequate paved shoulders can be used to assist in dispersal and breakup of platoons. Slower moving vehicles may temporarily use the shoulder to permit faster vehicles to pass, returning to the travel lane when passing maneuvers have been completed. In Texas and Canada, where some agencies construct wide shoulders for a total roadway width of 40 to 44 ft, a high percentage of the driving population uses the shoulder in this manner—partic- ularly in western Canada where long distance recreational travel is heavy during the summer. Illustration 8-2 presents a typical use of paved shoulders as described previously. Five states allow the use of shoulders for slow-moving vehicles at all times. An additional ten states permit such use under specified conditions. THREE -LANE HIGHWAYS Three -lane roadways are a rational intermediate solution to four -lane expansions for two-lane highways experiencing oper- ational problems. Because of funding and terrain constraints, three -lane roadways may be considered for spot and segment improvements. There are numerous methods for using the third travel lane on such segments. In the 1940's and 1950's, the third (center) lane was used for passing by vehicles in either direction—the first vehicle to oc- cupy the center lane had the right-of-way. This condition was found to be hazardous, particularly in hilly terrain. This use of three -lane highways in the United States has been generally discontinued. Other three -lane highway treatments are being safely and efficiently applied. including the use of passing lanes, turning lanes, and climbing lanes. Passing Lanes This three -lane roadway design assigns the third (center) lane to one direction of travel for a short distance (approximately 1 mile), then alternates the assignment of the passing lane to the other direction. This cyclic process may be continued along an entire highway section, or may be combined in an urban fringe area with two-way left -turn lanes and/or specific intersection turning treatments. In a rural setting, intermittently spaced passing lane sections have been successfully used to break up platoons and reduce delay. Two lanes are provided for unimpeded passing in one direction for 1 to 2 miles followed by a transition to two lanes Illustration 8-2. Slow-moving vehicle uses the shoulder of a two-lane rural highway. permitting faster vehicles to pass. TWO-LANE HIGHVV AYS 8-19 of similar design for the opposing flow. Advance signing advises motorists of the next upcoming passing lane to reduce driver anxiety and frustration. Two operational markings are practiced: passing m the single -lane direction may be permitted if passing sight distance is available, or passing in the single -lane direction may be prohibited. Figure 8-6 depicts these markings, and var- ious methods of providing for the transition when the direction of the passing lane is changed. Permissive passing for the one - lane direction is not used by some agencies when the AADT exceeds about 3,000 vpd. 3.

SPACING OF PASSING LANES ON TWO-LANE HIGHWAYS Two -Way Peak Hourly Volume (vph) 400 300 200 Distance to Next Passing Lane (miles) 5 6.5 9 An analytic study of passing lane requirements was conducted in Ontario, Canada (7). This study recommended that passing lanes should consistently be from 1.0 to 1.25 miles long. This length was found to be adequate to disperse most platoons, to provide for additional transition zones, and yet not be too long to change drivers' expectations about the true nature of the highway. Table 8-11 gives the recommended spacing between passing lanes in a given direction which resulted from the study. Continuous Two -Way Median Lett -Turn Lanes On two-lane highways having sizable left -turn traffic, a single travel lane in each direction often becomes subject to long delays as vehicles await opportunities to complete left turns. By pro- viding a continuous refuge area for left -turning traffic, the two- way left -turn lane can help to maintain through traffic capacity, with the added benefit of separating opposing flows. The ability to pass, however, is eliminated. Two-way left -turn lanes are not usually used where speeds are less than 25 mph or more than 50 mph, and are most often used in urban fringe areas or on a major route passing through a small town or village. Reversible Lane This is another use of the third (center) lane of a three -lane highway which is most applicable where travel demands are of a tidal nature—that is, extreme directional splits occur. The center lane is reversed by time of day to match the peak flow. The center lane is controlled by overhead signs or traffic signals indicating the direction of travel assigned at the time. Passing is not permitted in this application in the direction of the single lane. The reversible lane technique is most applicable to routes joining residential areas and high -employment centers, and for many recreational routes. Intersection Treatments Conventional analysis of two-lane highways assumes unin- terrupted flow, which is normally representative of rural con- ditions. With increasing development occurring in some rural areas, and in suburban fringe areas, the demand for high-volume access and egress can grow. Major intersections along two-lane highways become more common and important to the overall quality of flow on main routes. Adequate protected turning lanes for both left and right turns are useful in minimizing disruption to through traffic. Bypass lanes for through traffic may be con- sidered where a protected left -turn lane is not feasible, partic- ularly where paved shoulders are provided and/or where T - intersections are involved. Detailed analysis of intersections may be performed using the procedures of Chapter 9, "Signalized Intersections," and Chap- ter 10, "Unsignalized Intersections." Climbing Lanes Traditional climbing lanes also form three -lane cross sections when used in conjunction with two-lane highways. They are generally applied as a spot improvement, most often on steep, sustained grades which cause heavy vehicles, particularly heavy trucks, to travel at slow speeds. This reduces capacity, creates platoons, and increases delay. Additionally, safety problems may arise when the reduction in speed of heavy trucks exceeds 10 mph along the grade. Estimated operating speed characteristics of trucks are illus- trated in Figures I.3-1, I.3-2, and I.3-3 in Appendix I of Chapter 3. Resulting lengths of grade producing 10 -mph speed reductions are plotted in Figures 8-2 and 8-3, presented earlier in this chapter. AASHTO presently warrants a climbing lane wherever the speed of a 300-lb/hp truck is reduced by 10 mph or more and the volume and percentage of heavy trucks justify the added cost. One set of criteria that might be applied to reflect the economic considerations is: 1. Upgrade traffic flow rate exceeds 200 vph. 2. Upgrade truck flow rate exceeds 20 vph. 3. One of the following conditions exists: • Level -of -service E or F exists on the grade. . A reduction of two or more levels of service is experi- enced when moving from the approach segment to the grade. . A 10 -mph or greater speed reduction is expected for a typical heavy truck. These general guides for the consideration of climbing lanes on grades would apply only to climbing lanes on two-lane high- ways and should not be used in conjunction with consideration of climbing lanes on multilane highways. Turnouts The use of turnouts for improving the level of service on two- lane, two-way highways is more prevalent in the rolling and mountainous terrain of the western United States. Turnouts are short segments of a third lane added to one side of the highway or the other which permit slow vehicles at the head of platoons to pull off the main roadway, allowing faster vehicles to pass. Turnouts are used satisfactorily on both upgrades and down- grades. as well as on level terrain, to improve traffic flow. Imped- ing motorists are legally required to use turnouts where provided under certain prescribed conditions, which vary by state. A recent study of operational characteristics revealed that few drivers actually stop at turnouts (8). Several additional conclu- sions drawn from this study included: 1. Turnouts are safe when properly used. 2. A series of turnouts at regular intervals can provide con- siderable delay reduction. TWO-LANE HIGHWAYS 3. Turnouts are not a substitute for a passing or climbing lane of adequate length. 4. About 10 percent of all platoon leaders use properly des- ignated turnouts. 5. Large trucks tend to avoid turnouts. Turnouts are a short but functional treatment of irritating causes of operational delay. A western state recommends that the length of turnouts vary with approach speed according to the criteria of Table 8-12 (9). Approach speeds of potential turnout -users vary with pre- vailing traffic and roadway conditions, and differ between up- grades and downgrades. Turnout lengths of more than 500 ft are only used on downgrades exceeding 3 percent where high approach speeds are expected to exist. Lengths greater than 600 ft are never designed, as drivers may mistakenly attempt to use them as passing lanes. SHORT FOUR -LANE SECTIONS Short sections of four -lane cross section may be constructed along a primarily two-lane highway to break up platoons, to provide the desired frequency of safe passing zones, and to eliminate interference from low -speed vehicles. Such sections are particularly advantageous in rolling terrain, or where the alignment is winding or the profile includes critical grades from 8-21 TABLE 8-12. LENGTH OF TURNOUTS ON TWO-LANE HIGHWAYS Approach Speed (mph) 25 30 40 50 55 60 Minimum Length of Turn- out (ft) 200 200 250 375 450 535 both directions. The decision to use a short four -lane segment, as compared to using a three -lane option, may be based on long- range planning objectives for the facility, availability of rights- of-way, existing cross section. topography, and on the desire to reduce platooning and passing problems. The transition from a two-lane to a four -lane roadway should be designed to provide sufficient sight distance for passing. For the length of four -lane segments, AASHTO suggests that they be sufficiently long to permit several vehicles in line behind a slow-moving vehicle to pass before reaching the normal section of two-lane highway. Four -lane sections of 1.0 to 1.5 miles should be sufficiently long to dissipate most queues formed, depending on volume and terrain conditions. Further, it is noted that sections of four -lane highway, particularly divided sections, longer than 2 miles may cause drivers to lose their sense of awareness that the road is basically a two-lane facility. V. SAMPLE CALCULATIONS CALCULATION 1—FINDING SERVICE FLOW RATES FOR A GENERAL TERRAIN SEGMENT 1. Description—A segment of rural two-lane highway is ex- pected to have the following characteristics: a. Roadway characteristics -70 -mph design speed; 12 -ft lanes; 10 -ft paved shoulders; level terrain; 0 percent no passing zones; length = 5 miles. b. Traffic characteristics -70/30 directional split; 10 per- cent trucks; 5 percent recreational vehicles; 1 percent buses; 84 percent passenger cars. What is the capacity of the section? What is the maximum flow rate which can be accommodated at level -of -service C? 2.

The worksheet for general terrain sections may be used to perform these computations, as shown in Figure 8-7. CALCULATION 2 -FINDING LEVEL OF SERVICE FOR A GENERAL TERRAIN SEGMENT 1. Description -A two-lane rural highway carries a peak hour volume of 180 vph and has the following characteristics: a. Roadway characteristics -60 -mph design speed; 11 -ft lanes; 2 -ft shoulders; mountainous terrain; 80 percent no passing zones; length = 10 miles. b. Traffic characteristics -60/40 directional split; 5 per- cent trucks; 10 percent recreational vehicles; no buses; 85 percent passenger cars. At what level of service will the highway operate during peak periods? 2. Solution -The solution is found by comparing the actual flow rate to service flow rates computed for each LOS. The actual flow rate is found as: v = V/PHF where: T' = 180 vph (Given) PHF = 0.87 (Default value, Table 8-3, 200 vph) and: v = 180/0.87 = 207 vph Service flow rates are computed from Eq. 8-1: SF, = 2,800 x (v/c); X fd XL X fiv = 1/(1-PT(ET- 1)+PR(ER- 1)+PB(EB- 1)] where: v/c = 0.02 for LOS A, 0.12 for LOS B, 0.20 for LOS C, 0.37 for LOS D, 0.80 for LOS E (Table 8-1, mountainous terrain. 80 percent no passing zones); fd = 0.94 (Table 8-4, 60/40 split); f = 0.75 for LOS A through D, 0.88 for LOS E (Table 8- 5, 11 -ft lanes, 2 -ft shoulders); ET = 7 for LOS A, 10 for LOS B, C, 12 for LOS D, E. (Table 8-6, mountainous terrain); ER = 5.0 for LOS A, 5.2 for LOS B-E (Table 8-6, moun- tainous terrain); PT = 0.05 (Given); and PR = 0.10 (Given). Then: f„(LOS A) = 1/[1 + 0.05(7 - 1)+0.10(5.0- 1)] = 0.588 (LOS B, C) = 1/[1 + 0.05(10 - 1) + 0.10 (5.2 - 1)) = 0.535 (LOS D, E) = 1/[1 + 0.05(12 - 1) + 0.10 (5.2 - 1)) = 0.508 and: SFA = 2,800 x 0.02 x 0.94 X 0.75 X 0.588 = 23 vph SFB = 2,800 X 0.12 x 0.94 x 0.75 x 0.535 = 127 vph SF, = 2,800 X 0.20 X 0.94 x 0.75 X 0.535 = 211 vph SF, = 2,800 X 0.37 X 0.94 x 0.75 x 0.508 = 371 vph SFE = 2,800 X 0.80 X 0.94 X 0.88 x 0.508 = 941 vph If the actual flow rate of 207 vph (which represents the flow rate during the peak 15 min of flow) is compared to these values, it is seen that it is higher than the service flow rate for LOS B (127 vph), but is less than the service flow rate for LOS C (211 vph). Therefore, the level of service for the highway is C for the conditions described. This problem illustrates several points. On severe terrain, such as the situation for this problem, "good" operating conditions can be sustained only at low flow rates. The capacity of the roadway is also severely limited, reaching only 941 vph, which is approximately one-third of the ideal capacity of 2.800 vph. Note that the v/c ratio used in the computation of capacity is only 0.80. This is because all v/c ratios in the two-lane meth- odology are referenced to the ideal capacity of 2,800 vph, which cannot be achieved in severe terrain with passing sight distance restrictions. This solution may be summarized or done on the general terrain section worksheet, as shown in Figure 8-8. CALCULATION 3 -FINDING SERVICE FLOW RATES FOR A SPECIFIC GRADE 1. Description -A rural two-lane highway in mountainous terrain has a 6 percent grade of 2 miles. Other relevant char- acteristics include: a. Roadway characteristics -12 -ft lanes; 8 -ft shoulders; 60 percent no passing zones. b. Traffic characteristics -70/30 directional split; 12 per- cent trucks; 7 percent recreational vehicles; 1 percent buses, 80 percent passenger cars; PHF = 0.85. What is the maximum volume which can be accommodated on the grade at a speed of 40 mph (LOS D, Table 8-2)? 2. Solution -Service flow rate on specific grades is computed using Eq. 8-3, as follows: SF, = 2.800 X (v/c), X fd XL X f8 X f,,,- 8-24 where: f8 = 1/[1 + Po I,] from Eq. 8-4 I, = 0.02 (E - Ea] from Eq. 8-5 and: RURAL HIGHWAYS JHV - 1/[1 + PHV(EHV- 1)] from Eq. 8-6 EH, = 1 + (0.25 + PT/HV) (E - 1) from Eq. 8-7 The following values are used in these computations: (v/c)D = 0.83 (Table 8-7, 40 mph, 6 percent grade, 60 per- cent no passing zones); fd = 0.78 (Table 8-8, 70/30 split, 70 percent upgrade); f = 1.00 (Table 8-5, 12 -ft lanes, > 6 -ft shoulders); E = 10.7 (Table 8-9, 40 mph, 6 percent for 2 -mile grade); Eo = 1.3 (Table 8-9, 40 mph, 0 percent grade); PHV = PT+PR+PEI= 0.12+0.07 -r 0.01 = 0.20; and 0.12/0.20 = 0.60. PT/HV = PT/ PHV = Then, computing factors fg and fHV: 4 = 0.02 (10.7 - 1.3) = 0.188 f` = 1/[1 + (0.80 x 0.188)] = 0.87 EH, = 1 + (0.25 + 0.60) (10.7 - 1) = 9.25 fHV = 1/[1 + 0.20(9.25 - 1)] = 0.38 The service flow rate for the peak 15 min is now computed using Eq. 8-3: SFD = 2,800 X 0.83 x 0.78 X 1.00 X 0.87 x 0.38 = 599 vph Since the question asks for a maximum volume. rather than a flow rate, the service flow rate is converted to a full hour volume as follows: V = SFX PHF = 599 x 0.85 = 509 vph Thus, the maximum full -hour volume which can be accom- modated at 40 mph, or LOS D, on the grade described is 509 vph. The maximum flow rate is 599 vph. CALCULATION 4 -FINDING LEVEL OF SERVICE AND CAPACITY OF A SPECIFIC GRADE 1. Description -A rural two-lane highway in mountainous terrain has a grade of 7 percent, 2 miles long. It currently carries a peak hour volume of 500 vph. Other relevant characteristics include: a. .Roadway characteristics -60 -mph design speed; 11 -ft lanes; 4 -ft shoulders; 80 percent no passing zones. b. Traffic characteristics -80/20 directional split; 4 percent trucks; 10 percent recreational vehicles: 2 percent buses; 84 percent passenger cars; PHF=0.85. At what level of service does the grade operate? What upgrade speed can be expected during the peak 15 min of flow? What is the capacity of the grade? If the approach speed to the grade is 55 mph. what delay is incurred by vehicles climbing the grade? 2. Solution -The finding of capacity for a specific grade re- quires plotting of the service flow rate vs. speed curve which results from Eq. 8-3: where: and: SF,=2,800X (v/c);Xfdxf Xf. XfHV f8 = 1/[1 + Pp/p] 4= 0.02 (E -E,) f . = 1/[1 + PHV(EHV - 1)] EH,. = 1 + (0.25 + PT/HV) (E - 1) Capacity is found at the point where this curve intersects the speed at capacity vs. flow rate at capacity curve on the specific grade worksheet. The upgrade speed is found by entering this curve with the actual flow rate. To plot the curve, the procedure recommends computing service flow rate points for the following speeds: 55 mph (LOS A), 52.5 mph, 50 mph (LOS B), 45 mph (LOS C), 40 mph (LOS D), and 30 mph. These points would be plotted on the specific grade worksheet of Figure 8-5, and a smooth curve constructed. Once capacity is determined, the service flow rates for every LOS will be known, and the actual LOS can be determined by comparing the actual flow rate to the computed values. The following values are used in these computations: v/c = 0.00 for 55 mph 0.05 for 52.5 mph 0.15 for 50 mph 0.40 for 45 mph 0.64 for 40 mph 0.88 for 30 mph (Table 8-7, 7 percent grade, 80 percent no passing zones); = 0.70 (Table 8-8, 80/20 split); = 0.85 for 55-45 mph 0.92 for 45-30 mph (Table 8-5, 11 -ft lanes, 4 -ft shoulders): E = 88.0 for 52.5 mph 46.0 for 50 mph 22.8 for 45 mph 15.4 for 40 mph 8.2 for 30 mph (Table 8-9, 7 percent grade, 2 miles. no value given for 55 mph); Eo = 1.8 for 52.5 mph 1.6 for 50 mph 1.4 for 45 mph 1.3 for 40 mph. 30 mph (Table 8-9, 0 percent grade); P,, = 0.84 (Given); PHV = PT + PR +Pg = 0.04 + 0.10 + 0.02 = 0.16; and PT/HV = PT/PHV = 0.04/0.16 = 0.25. ld Values of fg may now be computed as follows: 4(52.5) = 0.02(88.0 - 1.8) = 1.724 (50.0) = 0.02(46.0 - 1.6) = 0.888 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 TWO-LANE HIGHWAYS (45.0) = 0.02(22.8 - 1.4) = 0.428 (40.0) = 0.02(15.4 - 1.3) = 0.282 (30.0) = 0.02(8.2 - 1.3) = 0.138 f, (52.5) = 141 + 0.84(1.724)] = 0.41 (50.0) = 1/[1 + 0.84(0.888)] = 0.57 (45.0) = 1/[1 + 0.84(0.428)] = 0.74 (40.0) = 1/[1 + 0.84(0.282)] = 0.81 (30.0) = 1/[1 + 0.84(0.138)] = 0.90 Values of fH,• are also computed: EHV(52.5) = 1 + (0.25 + 0.25)(88.0 - 1) = 44.5 (50.0) = 1 + (0.25 + 0.25)(46.0 - 1) = 23.5 (45.0) = 1 + (0.25 + 0.25)(22.8 - 1) = 11.9 (40.0) = 1 + (0.25 + 0.25)(15.4 - 1) = 8.2 (30.0) = 1 + (0.25 + 0.25)( 8.2 - 1) = 4.6 fHV(52.5) = 1/[1 + 0.16(44.5 - 1)] = 0.13 (50.0) = 1/[1 + 0.16(23.6 - 1)] = 0.22 (45.0) = 1/11 + 0.16(11.9 - 1)] = 0.36 (40.0) = 1/[1 + 0.16( 8.2 - 1)) = 0.46 (30.0) = 1/[1 + 0.16( 4.6 - 1)] = 0.63 Having computed all relevant factors, the total two-way ser- vice flow rates for the designated speeds may be computed: SPEED 2,800 X v/C X f X f.

These computations are summarized on the specific grade worksheet shown in Figure 8-9. The curve defined by these points is also plotted on the worksheet. The intersection of the plotted curve with the speed at capacity vs. flow rate at capacity curve indicates that capacity is 950 vph, total in both directions, which occurs at an average upgrade speed of 28.0 mph. To find the existing level of service, the volume of 500 vph is converted to a flow rate for the peak 15 -min period: v = V/PHF = 500/0.85 = 588 vph The plotted curve is entered on the worksheet with 588 vph, and the upgrade speed is found to be 37 mph. Because this speed is less than 40 mph, the minimum value for LOS D (Table 8-2), but greater than the speed at capacity (28 mph), the level of service is E. This can also be determined by comparing the actual flow rate of 588 vph with the service flow rate for LOS D (40 mph) of 430 vph and capacity (950 vph). The last part of this problem asks to find the delay incurred by vehicles traveling up the grade. "Delay" is defined as the difference in travel time experienced by vehicles traversing the upgrade at the existing speed and the travel time which would be experienced if they were able to maintain their approach speed on the grade. Thus: Travel time at 55.0 mph = (2 miles/55 mph) X 3600 sec/ hour = 130.9 sec/veh Travel time at 37.0 mph = (2 miles/37 mph) X 3600 sec/ hour = 194.6 sec/veh Delay = 194.6 - 130.9 = 63.7 sec/veh WORKSHEET FOR SPECIFIC GRADES Pap 2 V PLOT SF vs Sped 55 50 E 45 zo 35 c 6< 30 25 20 0 30C 500 1000 6500 2000 SERVIa FLOW RATE (vph) beeneavOn d Cm.aty Sped n Flow cure ..Nth Serve: Flow R.o. va Sped curve defiro C.paarx Si,. and +ped n Capacity. 5, 2500 2800 VL LEVEL OF =On ANALISIS SF LOS arc. 15.4.0er0 A B C 178 J D 40.0 E 440 Actual Flow Race 588 1 Level 0( Senn.

Description -A rural two-lane highway has a 4 percent upgrade of 1% miles, and has the following other characteristics: a. Roadway characteristics -level terrain approach; 12 -ft lanes; 8 -ft shoulders; 40 percent no passing zones. b. Traffic characteristics-DHV = 400 vph; 15 percent trucks; 5 percent recreational vehicles; 1 percent buses; 79 percent passenger cars; 60/40 directional split; PHF = 0.85. Is the addition of a climbing lane justified at this location? 2. Solution -It is assumed that a climbing lane on a two- lane highway is generally justified when the following conditions are met: 1. Upgrade flow rate is greater than 200 vph. 2. Upgrade truck flow rate is greater than 20 vph. 3. One of the following occurs: a. The grade operates at LOS E or F. b. The typical heavy truck reduces its speed by more than 10 mph on the grade. c. The LOS on the grade is two or more levels poorer than on the approach to the grade. Each of these conditions should be checked to justify the construction of the climbing lane: Upgrade flow rate = 400 X 0.60/0.85 = 282 vph > 200 vph OK Upgrade trucks = 400 x 0.15 x 0.60/0.85 = 42 vph > 20 vph OK To justify a climbing lane, only one of the conditions specified in item 3 must be demonstrated. The LOS will be E or worse if the actual flow rate exceeds the service flow rate for LOS D. This value is computed using Eq. 8-3: SF, =2,800X(v/c)DXfdXf.Xf,Xfin, where: f, = 1/[1 + P,I,] I,= 0.02 (E - E,) and: fHY = 1/[1 + PHV(EHV- 1)] EHE = 1 + (0.25 + Pr,Hv) (E - 1) The following values are used: (v/c)D = 1.00 (Table 8-7, 4 percent grade, 40 mph, 40 per- cent no passing zones); f, = 0.87 (Table 8-8, 60/40 directional split); f = 1.00 (Table 8-5); E = 3.8 (Table 8-9, 4 percent, 1% -mile grade, 40 mph); E, = 1.3 (Table 8-9, 0 percent grade, 40 mph); PH,,=0.15+0.05+0.01= 0.21; and PT/HV = 0.15/0.21 = 0.71. Using these values to compute the service flow rate at level - of -service D: = 0.02(3.8 - 1.3) = 0.05 f, = 1/[1 + (0.79 x 0.05)] = 0.96 EH,, = 1 + (0.25 + 0.71)(3.8 - 1) = 3.69 fHY = 1/[1 + 0.21(3.69 - 1)] = 0.64 SFD = 2,800 x 1.00 x 0.87 x 1.00 x 0.96 x 0.64 = 1,497 vph The actual flow rate is the DHV divided by the PHF, or 400/ 0.85 = 471 vph. As this is clearly less than the service flow rate for LOS D, the existing LOS is not E, and this condition is not met. The next condition to investigate is whether a 10 -mph speed reduction of heavy trucks would exist on the grade described. Based on the assumption that the typical truck on this grade has a weight/horsepower ratio of 200 lb/hp, Figure 8-2 is used to estimate the speed reduction experienced as shown below: UPGRADE (% 10 9 8 7 6 5 4 3 2 SPEED REDUCTION BELOW AVERAGE RUNNING SPEED OF ALL TRAFFIC (mph) 20 15 INITIAL SPEED= 55 mph 2000 4000 6000 8000 LENGTH OF GRADE (ft. ) It can be seen that the speed reduction will be well in excess of 20 mph, which is greater than 10 mph, fulfilling the last required condition for justifying a climbing lane. Note that because only one of the conditions in item 3 needs to be satisfied, it is not necessary to investigate the third condition. It can be concluded that a climbing lane is justified on the basis of the stated criteria. CALCULATION 6 -PLANNING APPLICATION 1 1. Description -A rural two-lane highway in mountainous terrain is located in an area where the design hour factor, K, is 0.14. What is the maximum AADT which can be accommodated without the LOS falling below D during the peak 15 -min flow period? 2. Solution -The solution is simply found by entering Table 8-10 with mountainous terrain, LOS D, and a K -factor of 0.14. The maximum permissible AADT is found to be 2,700 vpd. TWO-LANE HIGHWAYS CALCULATION 7 -PLANNING APPLICATION 2 1. Description -A rural two-lane highway is located in roll- ing terrain in an area where the design hour factor, K. is 0.12. Its current AADT is 5,000 vpd. What is the likely LOS during the peak 15 min of flow? 2. Solution -Again, the solution is straightforward using Table 8-10. The maximum AADT's for the various levels of service are found for rolling terrain and a K -factor of 0.12. The 5,000 AADT is seen to fall between the maximum values for LOS C (4,400 vpd) and LOS D (6,600 vpd). The LOS is therefore expected to be D during the peak 15 min of flow. CALCULATION 8 -PLANNING APPLICATION 3 1. Descriprion-A two-lane highway carrying an AADT of 6,600 vpd is located in level terrain in an area where the design hour factor, K. is 0.12. The area has a traffic growth rate of 5 8-27 percent per year. The responsible highway agency's policy is to expand two-lane highways to four lanes before the level of service becomes E during peak periods. In how many years will ex- pansion of the facility have to be completed under this policy? If it will take 7 years to construct a four -lane highway, how long will it be before the construction project should begin? 2. Solution -The policy requires that expansion of the high- way be completed before the AADT exceeds the maximum allowable value for LOS D. From Table 8-10, the maximum AADT for LOS D, for level terrain and a K -factor of 0.12, is 11,200 vpd. The question now becomes: How many years will it take an AADT of 6,600 vpd to grow to 11,200 vpd at a rate of 5 percent per year? Therefore: 11,200 = 6,600(1 + 0.05)" n = 10.9 years Construction should begin in 10.9 - 7 years, or in 3.9 years. VI. REFERENCES 1.

COLLINS, IN THE COLORADO RIVER, OR ITS TRIBUTARIES, TRIBUTARY INVOLVED: GARFIELD CREEK, IN GARFIELD COUNTY The above entitled Application was filed on July 12, 1991, and was referred to the undersigned as Water Referee for Water Division No. 5, State of Colorado, by the Water Judge of said Court on the 6th day of August, 1991, in accordance with Article 92 of Chapter 37, Colorado Revised Statutes 1973, known as The Water Right Determination and Administration Act of 1969. And the undersigned Referee having made such investigations as are necessary to determine whether or not the statements in the Application are true and having become fully advised with respect to the subject matter of the Application does hereby make the following determination and Ruling as the Referee in this matter, to wit: • 1. The statements in the Application are true. • 2. The name of the structures involved are Collins Pump and Collins Pump Alternate. 3. The name and address of the Claimant: Kenneth R. Collins; 2839 County Road 335; New Castle, CO 81647. 4. The source of the water is Garfield Creek, tributary to the Colorado River. 5. A) The point of diversion of Collins Pump is located in Lot 9, Section 4, T. 6 S., R. 91 W. of the 6th P.M. at a point whence the South Quarter Corner of said Section 4 bears East 10.0 feet, and S. 00°29'34" E. 1,405.81 feet. B) The point of diversion of Collins Pump Alternate is on the Colorado River at a point 1,900 feet from the South Section line and 2,750 from the East Section line of Section 4, T. 6 S., R. 91 W. of the 6th P.M. 6. On October 31, 1980, in Case No. 80CW238, the Water Referee for Water Division No. 5 awarded to Collins Pump, a conditional water right for 0.04 c.f.s., to be used for irrigation, with Appropriation date of June 4, 1979. The Claimant was directed to file an Application for Finding of Reasonable Diligence in the development of this conditional water right in October of 1984 to maintain said conditional water right in full force and effect. This Ruling of Referee was confirmed and made a Decree of the Court on December 3, 1980. • • • (VI -1991) Collins 91CW105 Ruling of Referee Page 2 7. In Case No. 81CW169, the 0.04 c.f.s. previously awarded conditionally to Collins Pump in Case No. 80CW238 was made absolute and unconditional. 8. On July 12, 1991, the Applicant filed in Water Court for Water Division No. 5 an Application for Change in Water Rights in which it is requested that, that Collins Pump Alternate at the location as described in paragraph 5b above, be established as an alternate point of diversion for the 0.04 c.f.s. previously awarded to Collins Pump in Case No. 80CW238. 9. On September 3, 1991, a Statement of Opposition was filed on behalf of Faye B. Faas. 10. On January 31, 1992, the Applicant and the Opposition agreed that the Applicant makes no claim to any permanent right and that the use of the land used to pump from the alternate point of diversion is fully at the discretion of the landowner and may be terminated at any point in time. 11. The alternate point of diversion on the Colorado River is only to be utilized when water is legally and physically available at the original point of diversion on Garfield Creek. No additional Statements of Opposition have been filed in this Case and the Statutory time for filing Statements of Opposition has expired. The Change of Water Right requested herein will not injuriously affect the owner of or persons entitled to use water under a vested water right or a decreed conditional water right, and the application should be granted pursuant to C.R.S. 1973, § 37-92-305(3), subject to the provisions in paragraphs 10 and 11 above. The Referee does therefore conclude that the above entitled application should be granted and that an alternate point of diversion of the 0.04 cubic foot of water per second of time previously awarded to Collins Pump in Case No. 80CW238 should be and hereby is established at the Collins Pump Alternate as described in paragraph 5b above subject to the provisions and agreement in paragraphs 10 and 11 above. It is accordingly ORDERED that this Ruling shall be filed with the Water Clerk Subject of Judicial review. It is further ORDERED that a copy of this Ruling shall be filed with the appropriate Division Engineer and the State Engineer.

W ITNESSETH WHEREAS, the Developer is the owner and holder of portions of Lots 8, 9, 12, SE1/4 SW1/4 of Section 4, Lot 10 of Section 5 and NW1/4 NE1/4 of Section 9, Township 6 South, Range 91 West of the 6th P.21., County of Garfield, State of Colorado; and WHEREAS, the County is authorized by the provisions of C.R.S. 1973, 30-28-101, et seq., to provide for the physical development of the unincorporated territory within the County and by the provisions of C.R.S. 1973, 29-20-104 to plan for and regulate the use of land by regulating development and activities in hazardous areas, regulating the location of activities and developraenfs which may result in significant changes in popula- tion density, providing for phased development of services and facilities, and regulating the use of land on the basis of the impact thereof on the community or surrounding areas; and WHEREAS, the Developer, pursuant to applicable County regula- tions and resolutions, has made application to the County for a zone district amendment and planned unit development approval to permfe-the construction and development of 317 residential lots and two multi-purpose commercial lots on the above-described property (which planned unit development project is known as and hereinafter referred to as "Wood Landing"); and WHEREAS, the County has caused to be constructed a public. road known as County -Road 335, which road is situate on the southerly side of the Colorado River between Alkali Creek and Divide Creek; and WHEREAS, Wood Landing is adjacent to said County Road 335; and WHEREAS, other persons also use or may use such road for any lawful purposes, and neither party can prohibit the lawful use to which such road is put by others; and WIIEIUAS, significant amounts of additional traffic will be generated on said County Road in the event residential and - commercial improvements are permitted to be constructed upon Wood Landing; and WHEREAS, the County has determined that the traffic impact of Wood Landing upon County Road 335 as it presently exists, would constitute a danger to the public safety which would prevent the County from approving the proposed zone district amendment and planned unit development; and WHEREAS, the County is unable to grant the requested zone district amendment and plan approval unless the Developer shall enter into an agreement to provide certain improvements to such road, as herein provided; and WHEREAS, the parties agree that such road as initially con- structed was never intended to support the increased traffic which would result from the construction land development of Wood Landing; and WHEREAS, the County by its Resolution No. 80-258 duly adopted on October 27, 1980, has indicated that it would approve the above-mentioned zone district amendment and planned unit develop- ment for Wood Landing subject to certain - conditions, one of which is that the Developer enter into and perform an agreement with the County wherein the Developer would, at Developer's expense, agree to make certain reasonable and necessary improvements to County Road 335. NOW, THEREFORE, in consideration of the premises and of the covenants herein contained, it is agreed as follows: 1. Attached hereto as Exhibit "A" is a narrative descrip- tion of the present condition of County Road 335 which the parties agree fairly and accurately represents the present facts as to the construction of such road and its present condition and a narrative description of the construction thereto to be provided by the Developer. 2. The Developer agrees to contract with an engineering firm to design and provide the necessary engineering services for the road improvements described in Paragraph 1 above. The Developer agrees that the engineering firm to be employed as above provided shall be subject to°the prior approval of the County, which ap- proval shall not be unreasonably withheld. Notwithstanding the above, Eldorado Engineering or KKBNA, Inc. are approved. Said engineering firm shall also be responsible for preparation of any necessary specifications or drawings. In addition, said engineering firm shall be responsible for periodic inspection of construction of said road improvements as required. 3. The Developer or Engineering Firm shall keep the County apprised of all construction activities and shall furnish the County with all required test results, soil reports and other data, if any, accumulated in the construction of the road. 4. The parties acknowledge that a portion of the road im- provements contemplated by this Agreement require relocating and reconstruction of certain portions of County Road 335 over and across lands not presently owned by the County. The Developer will provide the County with a description of the improvements as constructed and will furnish the sixty -foot rights-of-way and evidence of legal title sufficient to provide the County with a right-of-way, as provided for in Exhibit "A", across any property that must be acquired for road relocation. In the event the Developer is not able to acquire such rig]ts-of-way by the time of recordation of the final plat of Wood Landing, the Developer , shall by that date provide the County with all documentation necessary to establish the value of the properties to be acquired, including an adequate appraisal by a mutually acceptable member of MAI or equivalent, and the County shall then proceed with condemnation proceedings, if necessary, to acquire the necessary rights-of-way to permit construction to proceed as contemplated by this Agreement. S. The Developer shall pay directly for all construction and shall pay for or reimburse the County for all costs associated with road development, all as provided for in Exhibit "A", including, but not limited to, reasonable attorney's fees and appraisals, and right-of-way acquisition costs, the amount of any condemnation awards and/or for the amount of any negotiated settlement with the land owner providerl that such negotiated settlement shall have been approved by the Developer in writing prior to or concurrently with the negotiated"settlement. In the event the Countyshall not have obtained possession of any right-of-way on or before 90 days following recordation of final plat of Wood Landing, the Developer shall not be required to realign any portion of County Road 335 for which the County has not obtained the necessary right-of-way, but the Developer shall chip and seal (as defined in Exhibit "A") the existing roadway within the existing right-of-way. 6. The acquisition of all necessary rights-of-way, legal title and all associated road improvement costs and all funds advanced by the Developer and the fair market value of all pro- perties conveyed by the Developer to the County for these purposes shall be collectively considered grants-in-aid from the Developer to the County. Thereafter, as in the past, County Road 335 shall continue to be the property of the County and the Developer agrees that it will have acquired no interest*in the improved realigned road. Private uses in the existing right-of-way will be either preserved or transferred to a new location, the expense of which will be treated as road relocation expense. Said road is being paid for by the Developer under this Agreement solely to comply with terms and conditions imposed by the County's Resolution No. 80-258 in connection with the rezoning and planned unit development application related to Wood Landing. Any portions of the present road which the County may determine no longer to be required for public use because of realignment of County Road 335 shall be vacated by the County and become the property of the adjoining landowners as provided by C.R.S. Section 43-2-113 (1973)-, and the Developer likewise shall acquire no interest therein except to the extent that any of them is the adjoining property owner. The roadway relocation and all construction shall be completed within 24 months after commencement of construction of public improvements in the subdivision of Wood Landing, except for road relocation and bridge construction at Garfield Creek, which shall be completed prior to issuance of a certificate of occupancy of any building within Wood Landing. During construction no land owner shall be prevented from having access to his property excepting only construction delays ofup to thirty minutes. The County shall maintain such road during construction to the extent feasible and after completion of construction in a manner consis- tent with maintenance which it performs with respect to similar roads in the County primary road system in conformity with the provisions of C.R.S. Section 43-2-111 (1973). 7. It is specifically agreed between the County and the Developer that this Agreement is being entered into based upon the current status of development in the area affected by County Road 335, which is that no further development is under consideration by landowners of which the County is aware, and consequently the sole reason for the relocation and reconstruction of County Road 335 is due to the development of Wood Landing. The Developer has agreed to provide the road improvements required by the within agreement and the Developer and the County desire to provide for the contribution to such construction by any other subdivider or subdividers whose projects will enjoy the direct benefits of the road reconstruction which will result.from this Agreement. Accor- dingly, the County has determined that those lands contained in the Garfield Creek drainage and those lands contained within Township 6 South, Range 91 West of the 6th P.P. which are south of the Colorado River, west of the Garfield Creek drainage and northeast of the Divide Creek drainage, will directly benefit from the construction provided herein, and the County shall req4ire as a condition precedent to authorization of any subdivision upon such lands within ten years after the date of this Agreement, anv subdivider shall repay to the Developers the amount proportionately associated with each lot thereby subdivided, at a rate of $125.00 for each residential lot or dwelling unit and $500.00 for each non-residential acre included in a subdivision or Planned Unit Development, except land dedicated for public use shall be ex- cluded. In the event the Developer is associated with any develop- ment in the aforedescribed area, it agrees that any such development shall be bound by and participate in such reimbursement. It is expressly agreed that the total sum to he reimbursed to the Developer shall not exceed eighty percent (80%) of the actual cost of acquisition and construction as provided for in Exhibit "A", which is estimated to be $250,000.00. All costs shall be documented for and provided to the County prior to the time of any reimbursement obligation. 8. The Developer agrees to provide to the County, concur- rently with the final platting of any portion of Wood Landing, security and collateral to guarantee the Developers'.performance hereunder, in the form of a completion and performance bond issued by a corporate surety company licensed to do business in the State of Colorado, in the amount of 5250,000.00, to insure the acquisi- tion of land and construction of improvements as provided for in Exhibit "A". It is further mutually agreed that, as the roadway improvements are completed, the Developer may apply to the Board of County Commissioners for a release of all or part of the colla- teral deposited with the Board. Upon inspection and approval, the Board may release a proportionate amount of the collateral, retaining sufficient collateral to assure completion of this Agreement. If the Board determines that any of the roadway is not and will not be completed in compliance with the specifications within the time herein above limited, it shall furnish the Developer with a written list of specific deficiencies and shall be entitled to withhold collateral sufficient to ensure such substantial compliance. If the County determines that the Developer will not construct any or all of the improvements in . accordance with all of the specifications, the County may require and shall receive from the surety such funds as may be necessary to construct the roadway in accordance with the specifications, the County may require and shall receive from the surety such funds as may be necessary to construct the roadway in accordance with the specifications, limited to the amount of the completion performance bond stated above. 9. In the event that any provision or provi$ions of this Agreement are found to be, or become, illegal or unenforcable by a Court of competent jurisdiction, the remaining provisions of this Agreement shall remain in full force and effect unless any party hereto is materially and adversely affected by such -6- illegality or enforceability. If any party is so materially and adversely affected, such party shall have the right to terminate this Agreement by reasonable written notice to the other party. It is mutually agreed that a determination by a Court of competent jurisdiction that the reimbursement terms are not enforceable shall not permit the termination of this Agreement, nor excuse performance of Developer's obligations hereunder. 10. The Developer shall indemnify and hold harmless the County from any and all damages and costs, of whatsoever nature, which might be incurred, in or as a result of any action resulting from the County's efforts to enforce the reimbursement provisions of this Agreement with reference to any activities occurring in those portions of Garfield County defined as the affected area in paragraph 7 hereof including but not restricted to. litigation which might result there- from. In the event of such litigation involving the aforesaid reim- bursement provisions, the Developer shall participate in such litiga- tion as the true party in interest, ana the County may choose to assume the posture of a "stakeholder" in any such litigation. Inasmuch as the Developer has a direct interest in the outcome of any litigation arising from the eforts of the County to collect the reimbursement to which the Developer might be entitled as well as the costs and expenses involved therein, it is agreed that the County shall not institute such litigation without providing the Developer with ten days' notice of its intention to commence such litigation, within which period the Developer may decline any claim to the reimbursement at issue and the County will be released from its obligation to pursue such reimbursement. The County shall also provide the Developer of notice of any lawsuit against the County related to the collection of reimbursement within twenty days of service upon the County. Such notice shall not be required prior to the defense of any suit in which the County may become involved. 11. In the event, pursuant to the provisions of this Agree- ment, any party is not obligated to perform its obligations as herein provided by reason of the default of another party, or of the failure of any condition precedent or subsequent applicable to such party, excepting any reimbursement provisions found not to be enforceable, then any such party who is not obligated to perform may terminate this Agreement by notifying the other party in writing and thereupon this Agreement shall be terminated without futher obligation or liability upon any of the parties hereto. 12. For the purposes hereof, all notices shall be in writing and shall be deemed delivered either when delivered personally or when deposited in the United States mail, by certified mail, postage prepaid, addressed as follows: Developer: Post Office Box 1274 Littleton, Colorado 80160 County: Board of County Commissioners of Garfield County Garfield County Courthouse Post Office Box 640 Glenwood Springs, CO 81601 13. Nothing contained herein shall constitute an agreement or admission or a declaration or any kind that either party is the agent or representative of the other party, and each party hereby declares that no agency is hereby created between the parties hereto. 14. This Agreement sets forth the entire understanding and agreement between the parties with reference to the relocation and reconstruction of County Road 335, represents a merger of all previous agreements relating thereto, which are deemed to be of no force or effect except to the extent referred to herein, and may not be altered, amended or modified or terminated other than in writing agreed to by all parties hereto. 15.

We continue to have several seri us concerns with the project as it impacts our quality of life in this rural area. Most of the resiences in this area maintain large acreages for livestock, crops, etc. This lifestyl is highly valued by the homeowners. We have chosen to live in this area rathe than in town because of the low density. To add a subdivision to this rural area would change the makeup of the area and adversely affect the attractiveness of our property. Mr. Hilton does not live in this rural area, nor does he intend t do so. However, he would profit greatly financially at the expense of thos of us trying to maintain a rural lifestyle. With the 1,200 Subdivision, an (which is appro inconceivable to subdivision in a be required. The main road project. Iinpro expense require of hillside that Hilton to financ fund. The cou ago. However, these past dein I t Castle Valley Subdivision, the Burning Mountain the 1,400 (or more) unit subdivision planned for the Silt area ately five miles from Mr. Hilton's property), it seems us that it would be necessary for the county to approve a rural area that would not easily adapt to the changes that would ay (County Road 335) would not be adequate for such a housing g the road would be unfeasible by Mr. Hilton given the extreme to widen the road, develop new ditches, and remove large areas e naturally steeply graded. It would not be feasible for Mr. such changes and would, therefore, be left for the county to ty rejected previous proposals for this same reason five years vith the change of board members, perhaps Mr. Hilton is hoping s of his plans will go unnoticed. At yet another eeting discussing Mr. Hilton's plans, the necessity of a new bridge was a m.jor contention and his plans were rejected. When the county later built a new bridge, Mr. Hilton came up with yet another proposal. Once again Mr. Hilton is attempting to afford himself the greatest gain at our expense. Our lifestyle would also be impacted by limiting our freedom to safely walk, bike and horseback ride on the road. We would be required to live as though we lived in town. Additionally, in the event that we chose to sell our property, we could no longer be afforded the advantage of offering our property as an exclusively rural area. It is our hope that the board will consider the numerous previous proposals that were rejected, consider the extreme expense to the county to afford Mr. Hilton his enormous profits, and consider the effect this will have on those of us who desire to maintain a rural lifestyle. In all the years that Mr. Hilton has been attempting to force his plans through, I have never heard one resident in our area approve of the subdivision. In plain terms, no one wants it here! The only one to profit from such a proposal is Mr. Hilton himself. The county will have a hard time explaining to the taxpayers why this enormous expense is required so that Mr. Hilton can put a subdivision in the middle of the country.

A turnout was discussed. I believe the discussion was resolved by our agreement to again contact RE -2 for the purpose of learning what type of provision would best suit the District's needs. Leonard Eckhardt contacted me by phone the following day. Leonard is the Superintendent for RE -2. He indicated that he thought RE -2 had responded prior to the meeting before the commissioners but either that had not happened or the response had been misplaced. In either case, RE -2 did not feel that they needed to make any "special request" for bus pull off facilities in the case of The Rapids on the Colorado subdivision.

Loch head Executive Director Hal D. Simpson State Engineer Dear Mr. McCafferty: We have received additional information regarding the above referenced submittal. The proposed development includes 40 residential Tots on a 97 acre tract located 2 miles southwest of the Town of New Castle, Colorado. A central water supply system from on-site wells drilled in the alluvium of the Colorado River is proposed as the water source for the development. Water rights from Moore Ditch, transferred in Case No. W-3262, will provide augmentation water for depletions from the on-site wells. The augmentation plan decreed in Case No. W-3262 authorizes to provide water service to 9,700 residential equivalent units on the applicant's land which includes the subject 97 acres. Depletions from a number of structures including three wells located on the subject property are included in the plan. Our records indicate that these three wells were permitted but they appear to have expired and we have no evidence in our files that they have been constructed. The decree states that prior to its implementation, the applicant shail provide the Division 5 Engineer the location and number of acres of land to be permanently removed from irrigation, the water rights historically used for their irrigation, the particular structures to be augmented along with their locations and sources, the number of residential equivalent units to be supplied by the structures, the type of wastewater disposal systems, and the number of landscape acres to be irrigated, and the resultant number of acre-feet of depletions to be replaced. A letter dated May 21, 1996 from Enartech Inc. to Mr. Orlyn Bell, the Division Engineer, states that the source of water supply for the central water system will be two wells, augmented with the applicant's water rights in the Moore Ditch. The applicant's entire 70 acres under the Moore Ditch will be removed from irrigation. Each of 40 residential lot owners will be restricted to 10,000 square feet of lawn and garden irrigation. One acre of Mr. Eric McCafferty Page 2 June 20, 1996 lawn and garden will be irrigated on lot 19. The total consumptive use during the irrigation season for domestic use, the irrigation on 40 lots and on Lot 19 are estimated as 0.773 acre- feet, 18.365 acre-feet and 2 acre-feet respectively. Wastewater disposal system will be by (non -evaporative) leachfields for all 40 residences. Water Supply Design Report for the subdivision indicates that the total maximum supply required for the subdivision is 73 gpm, and the two existing wells have a combined sustained yield of 105 gpm. The report claims that with a storage of 118,000 gallons of water, the wells will be capable of serving the needs of the development. Pursuant to Section 30-28-136(1)(h)(I), C.R.S., it is our opinion that the proposed water supply will not cause injury to decreed water rights. Based on the analysis and pumping tests, it appears that the water supply is adequate. Please note that the long term adequacy of any ground water source may be subject to fluctuations due to hydrological and climatic trends. Our records indicate that the well permits have expired. The developer must obtain proper well permits prior to any use of these wells. If you have any questions regarding this matter, please feel free to contact Mr. Kris Murthy of this office or Mr. Orlyn Bell of our Division office in Glenwood Springs at 945-5665.

Lochhead Executive Director Michael B. Long Division Director Vicki Cowart State Geologist and Director Re: Proposed Rapids on the Colorado Subdivision -- West of Garfield Creek and North of C.R. 335, Garfield County Dear Mr. McCafferty: At your request and in accordance with S.B. 35 (1972), we have reviewed the materials submitted for and made field inspection of the site of the proposed residential subdivision indicated above. The following comments summarize our findings. (1) This entire subdivision parcel is an ancient alluvial fan which has formed out onto and partially over an older gravel terrace of the Colorado River. The alluvial fan has been incised on its east end by modern Garfield Creek. The origin of the alluvium on the fan is the Wasatch Formation cliffs which are the sources of material that accumulates in several small drainages on the south side of the county road. The site is presently an agricultural field and is man -modified as a result. There is some possibility that flash flooding during heavy rainstorms could carry material out onto the alluvial fan now, but this possibility seems poor considering the modern vegetation on the fan, lack of visible fresh deposits, and the obstacle that the county road creates. At the distal (near the River) end of the alluvial fan, the proposed developoment parcel is bounded by the modern floodplain of the Colorado River and the River itself. (2) The original 1980 geotechnical report by Lincoln DeVore, Inc. (included with the submittal), does and adequate job of characterizing the potential geology -related development problems for this site. Apparently and at that time, much higher density residential development was planned. Their test -hole data (indicated on Page 11) supports our interpretation of the area as an alluvial -fan feature that has formed on top of a terrace. From the standpoint of foundation engineering and design, the fine grained materials derived from the Wasatch may be relatively low density and underconsolidated, i.e., subject to settlement. Also, the gravels below them may be saturated because of a seasonally shallow ground -water table caused by irrigation in the area and infiltration of water from the drainages. For these reasons, and because of the variability in thickness of the alluvial- Mr. Eric McCafferty June 28, 1996 Page 2 fan materials, we recommend that each building site be investigated by a qualified soils and foundation engineer. (3) Considering what is shown on the submitted plat map which is on a topographic base, it would appear that proposed Lots 1 to 10 (inclusive) may be subject to flooding hazards from the Colorado River. We did not receive any studies or other documentation that addresses this possibility. If it has not been done already, a determination of the flooding hazard presented by the Colorado River to this parcel should be made and, if necessary, the plat adjusted accordingly. If the recommendations made above and those in the Lincoln-DeVore report are followed and made conditions of approval of this subdivision proposal, then we have no geology - related objection to your approval of it.
