Dear Commissioners: I am writing to formally request Preliminary Plan approval for Riverbend, Filing #5, A zone district and text amendment and Sketch Plan for this project were approved by the Board of County Commissioners on June 5, 1995. This project, as proposed, includes 1 1 single-family lots and five 2-family lots. The property is located immediately west of the existing Riverbend Subdivision near New Castle. I anticipate build-out of the existing Riverbend lots this year. I am requesting approval of this subdivision so I can continue to supply the current demand in Garfield County for moderately priced housing. Thank you for your time and consideration in this matter.

RIVERBEND FILING #5 PRELIMINARY PLAN INTRODUCTION Riverbend Filing #5 is located approximately 3 miles east of New Castle on the south side of the Colorado River in Section 34, Township 5 South, Range 90 West of the Sixth Principal Meridian. lt lies between County Road No. 335 and the Colorado River approximately 2.3 miles east of the New Castle interchange. The majority of this 10.61 acre property slopes gently towards the river at an elevation ranging from 5630 to 5600. On the northern edge of the parcel, the property slopes fairly steeply down to the river, with a river bank ranging from 20 to 25 feet high. Vegetation on this property is sparse, consisting primarily of bunch grass and sage brush. A few juniper trees, ranging in size from six inches in diameter to twelve inches in diameter are located near the northeast corner of the property. Two small natural drainages cross the property from South to North and drain into the river. Because of the relatively steep river bank, only the area immediately adjacent to the Colorado River will be subject to flooding during a 1O0 year flood. This property is currently zoned Planned Unit Development. On June 5, 1995, the Board of County Commissioners approved a zone district and text amendment to the existing Riverbend P.U.D. as it affected this property. This change was made in order to clarify some rather ambiguous information contained in the original P.U.D documents, and to establish the zoning regulations for this property. Under that approved zoning, the applicant is now requesting preliminary plan approvalto allow for subdivision into 16 lots, each having an area of approximately one-third of an acre. Five of the lots are designed for two-family units, and eleven would be single- family lots. Nearly four acres will be retained as Open Space giving an average density of 0.51 acres per unit. These lots would be similar in size to the adjacent Riverbend Subdivision, Filing No. 1, and would be served by an extension of the existing water and wastewater facilities which now serve Riverbend Subdivision. Riverbend Subdivision, Filings No. 1 and 2, which were subdivided in the late 1970's, lie south of the county road just east of this property. The existing filings contain 46 lots 1 which range in size from 0.36 of an acre to 0.82 of an acre with an average lot size of O.51 of an acre. This is the same density as the proposed subdivision. Riverbend Ranchettes which is composed of three lots averaging 1.95 acres is located to the north and east of Biverbend Subdivision. Homeowners in Biverbend #5 will automatically become members of a new Homeowner's Association which will be created for this subdivision. lt is intended that the existing water and wastewater facilities now operated by RB Homes, lnc. will be transferred to and managed by the Homeowner's Association. The Homeowner's Association will provide additional services such as road maintenance, and maintenance of the open space. Protective Covenants for the subdivision will address such issues as dog control, architectural control and administration of the Homeowner's Association. ACCESS The access to this property is provided by County Road No. 335 from the New Castle interchange with lnterstate 7O. This road is a two lane paved road which serves the existing Riverbend Subdivision. The road dead ends immediately past that subdivision. Riverbend Filing #5 will include a new interior loop road which will provide access to all lots in the subdivision. This road will be constructed to the standards of a "Rural Access Road", and will include two 1 1 foot lanes with 6 foot shoulders in a 50 foot wide right of way. The surface will be chip and seal. No on street parking will be allowed. UTILITIES Domestic and lrriqation Water Water for domestic and irrigation use will be provided by the same water system which currently serves Riverbend Subdivision, Filings No. 1 and 2 and Riverbend Ranchettes. This system is fed by Riverbend Wells No. 3 and 4 which were decreed in water court under Case No. W-2125 on July 23, 1974. ln addition, three additional wells, Riverbend Wells 1,2 and 5, which were decreed in the same case, have been drilled and will be put into service as the demand for water dictates. Each well has a decreed right of 0.67 cubic feet of water per second. The decree provides for municipal use, including domestic, irrigation incidental thereto and sewage treatment, recreation, fish and wildlife propagation and all other beneficial purposes, including storage Jor each of the above purposes. Previous pump tests for these wells have yielded 24O gallons per minute for Biverbend Well No.3 and 260 gallons per rninute for Riverbend Well No. 5. Water usage requirements, as shown in Exhibit A, are well below the capacity of these wells. Water storage for Riverbend Subdivision in currently provided by a 30,000 gallon water storage reservoir located on the hill above Filing No. 2atan elevation of 5960. This storage will be augmented by the construction of an additional 30,000 gallon storage tank by RB Water and Sewer Company. The size of this tank was recommended by the Burning Mountain Fire Protection District and exceeds that needed for domestic use. The existing 6" water lines within Riverbend Subdivision will be extended and looped through this subdivision to provide service for the new lots. Fire hydrants are provided at spacings of less than 5OO feet as required by the Burning Mountain Fire District. Wastewater Treatment Wastewater treatment for this subdivision is currently provided by RB Water and Sewer Company. This facility will be transferred to the Homeowners Association under a separate agreement. The existing treatment ponds are being relocated to an area closer to the river and the facility is being upgraded in order to bring the system into compliance with current Department of Health regulations. The new facility will consist of two aerated partial-mix lagoons and a settlement basin and will provide secondary treatment to the wastewater. The final effluent will be chlorinated and then discharged to the Colorado River. An application for a discharge permit has been applied for and is being reviewed by the Colorado Department of Health. The new system has been designed to accommodate the addition of an additional 21 units. The old treatment lagoons will be abandoned and reclaimed under criteria established by the Colorado Department of Health. It should be noted that the outflow from the new wastewater treatment plant will flow into the river near the northeast corner of this property. The effluent from this plant will be treated and then chlorinated prior to release according to standard practice and State Health Department regulations. The changes which are currently being made to this wastewater treatment facility are required to bring the plant into conformance with current State Health Department regulations. lmpacts associated with this change should be associated with the current development of Riverbend Subdivision, and are not created by the development of this new property. The wastewater treatment facility has sufficient capacity to handle the proposed 21 additional units. Based upon current information, there are approximately three persons per dwelling unit in Riverbend. Using this occupancy, and 80 gpcd, equates to an average daily flow of 240 GPD/unit. The 68 total units would have a total flow of 16320 GPD. This is 81.8o/o of the new capacity. Transfer of Water and Wastewater Facilities The water distribution system and wastewater treatment facilities currently serving the existing Riverbend Subdivision will be extended to serve Riverbend Filing #5. Ownership of these systems will be transferred pursuant to and coincident with the formation of a Homeowners Association as governed under the Colorado Common lnterest Ownership Act. Coincident with the above transfer of title, said Homeowners Association will assume the obligations currently being performed by RB Water and Sewer Company to provide water and sewer service to the homeowners in Riverbend Filings #1 and #2 and Riverbend Ranchettes. The Homeowners Association for Riverbend Filing #5 shall be structured to enable owners in Filings #1 and #2to join and, thus, obtain proprietary rights in the water and sewer system. Documents to facilitate this transfer are currently being drafted. Electric Service Electric service for this area is currently provided by Public Service Company. An existing overhead line is located along the north side of County Road No. 335. New service will be installed underground from the existing overhead line to serve this subdivision. Teleohone Service Telephone service is provided by US West to this area. An existing line is located on the south side of County Road No. 335, and has adequate capacity to serve this developrnent. The new service will be extended underground using a joint trench agreement with Public Service Company. Natural Gas Service Natural gas is not available in this area at this time, and there are no plans for extending service in the near future. Homeowners in this subdivision can choose to use propane to heat their homes through individual agreements with the gas company, or they can choose to have all electric service in their homes. Cable Television Service TCI Cablevision provides cable service to residents in the New Castle area, but at this time does not have cable service this far outside of town. The cost of extending cable for this number of lots would be prohibitive, so it is unlikely that cable television service will be made avaitable to this subdivision. However, newer techriology such as Primestar satellite systems are available at a relatively low cost. This will probably be the option of choice for this subdivision. OPEN SPACE AND PARKLAND Two areas of Open Space will be created on this property. The first and largest area will be an area of 3.32 acres along the Colorado River. A 25' river access easement will be dedicated to the public along the western side of the property to provide for public access to the river for fishing and other recreational uses. The wastewater treatment facility for this subdivision will be built on an easement within this Open Space area. Landscaped berms will be built around the treatment ponds to screen them from the view of the adjoining lots. The site will also be properly fenced to keep people and animals away from the treatment facilities. The second area of Open Space will be in the middle of the subdivision so it can be easily accessible to everyone who lives there. This area, approximately 0.64 of an acre in size will be owned and maintained by the Homeowner's Association. Because of its central location, it will function very well as a playground for small children or as a playing field for the families who will live here. ln addition to the Open Space being dedicated as a part of this filing, a school site has already been dedicated. lmmediately across the County Road from this site is a ten acre parcel which was dedicated to Garfield County as a school site when the first filings of Riverbend were developed. GEOLOGY AND SOILS The soils on this site are Heldt clay loam on three to six percent slopes. The site was evaluated by CTL/THOMPSON, lNC., Consulting Engineers during July, 1995. They believe the site is suitable for residential construction. The dense to very dense silty gravels will provide excellent support properties for the proposed roads and buildings. (See Preliminary Geotechnical lnvestigation attached). DRAINAGE The new lots and roads will have minimalimpact on historic drainage patterns. Off-site runoff from the south is collected by County Road 335 and diverted eastward into an existing 24" culvert. The outlet channel for this culvert, which currently flows through Lot g, will be relocated within the County right-of-way for approximately 100 feet. Drainage from the new roads and lots will be collected in roadside ditches which flow to a 15" CMP at the low point. This culvert discharges into a grassed swale which will flow eastward to the same natural drainage path as the 24" culvert. From there runoff will flow to the Colorado River, which is only a few hundred feet away. VEGETATION AND WILDLIFE Vegetation on this property consists of native grasses and weeds. The only trees within the property are some fairly large juniper trees located near the northeast corner of the property. These trees range in size from six to twelve inches in diameter. Since these trees are located in the open space area to the east of the proposed wastewater treatment facility, they should not be impacted by this development. This area is not an important habitat for wildlife. The Colorado Division of Wildlife GIS files, 1993 indicate that critical habitat and severe winter range for elk is located on the hillsides to the south and west of this property, and atso on the hillsides north of the Colorado river. Although mule deer may be seen here, their critical habitat and severe winter range is also located primarily on the hillsides to the west of this property. Bald eagles and other raptors can be seen flying over this property occasionally. However, because of the lack of large trees and other suitable nesting sites on this property, it is unlikely that this development will disturb important habitat for these birds. ; roport\9O2OOB.pp 07t26195 7 EXHIBIT A.

EXHIBIT C - SOILS AND GEOLOGY July 24, 1995 Schmueser Gordon Meyer, lnc. 118 W. 6th Street, Suite 200 Glenwood Springs, CO 81601 Attention: Ms. Debbie Dooley Subject: Preliminary Geotechnical lnvestigation Riverbend By The River Garfield County, Colorado Job No. GS-1586 We have per{ormed a preliminary geotechnical investigation for the planned Riverbend By The River development in Garfield County, Colorado. We believe this propedy can be developed for residentialconstruction. This letter presents a description of general site conditions, subsurface conditions found in our test pits and our opinions from a geotechnicalviewpoint and map showing interpreted Soils Conservation Service (SCS) soil type boundaries with a table of soils types. We understand that residential buildings will be built and approximately 900 linear feet of road. The subject site is approximately 10.6 acres located on a alluvial terrace above and to the south of the Colorado River. Access to the site is from County Road 335 from the New Castle/l-7O interchange which is approximately 2 miles to the west. The existing Riverbend Subdivision is across County Road 335 to the southwest. Land to the south, east and west has not been built on. Three excavated pits for a planned wastewater treatment facility are on the property adjacent to the north with the Colorado River beyond. Ground surfaces at the site slope down to the noilh at grades measured and visually estimated at 2 to 6 percent. We were told an existing sewage disposal pond approximately 360 feet by 160 feet in plan dimension that is on the central part of the site is to be removed. Vegetation consists of native grasses and weeds. Four (4) test pits were excavated at the locations shown on the attached Figure 1 to investigate subsudace conditions. Excavation was directed by our engineering geologist who logged the soils and obtained samples. Our test pits TP-l through TP-3 penetrated a 0.5 foot layer of soft, organic, sandy clays underlain by stiff to very stiff, silty to sandy clays. Our test pit TP-4 penetrated 1.0 foot of medium stiff, sandy clays with scattered gravels and some roots and vegetation underlain by dense to very dense, silty CTL/THOMPSON, INC. CONSULTING ENGINEERS 234 CENTER DRTVE r GLENWOOD SPR|NGS, COLORADO 81601 r (97O) 945_2809 to sandy gravels. No free groundwater was found in our test pits during our field investigation. Exposures of the Cretaceous aged Mancos Shale were obselved in the riverbank north of the site at approximately elevation 5580 feet. Assuming a generally horizontal bedrock surface, which is consistent with the geologic environment aithe site, we believe bedrock will be encountered at a minimum depth of 20 feet below north parts of the site and likely in excess of 40 feet below south parts of the property. The dense to very dense silty gravels will provide excellent support properties for the proposed roads and buildings. The stiff to very stiff, silty to sandy clays may be expansive. Building foundations may need to be designed to resists potential swelling of the clays. The removal of the existing sewage pond will resuh in fill being placed on lots 10, 11, 15 and 16. We do not recommend founding buildings partially on fill and partially on natural soils. Fill placed below foundations witl need to be moisture treated and densely compacted if it is to be below new construction. A design level geotechnical investigation will be needed to determine geotechnical criteria for building foundations and road design.

I have attached a copy of the Colorado Department of Health discharge permit issued for the Riverbend waste water treatment facility. I have had discussions with Dwain Watson of the Colorado Department of Health in regard to average density. They currently use 3.5 people per dwelling unit to estimate flows. He mentioned there is current census information available suggesting this number to be closer to 2.5 people per dwelling unit. Currently in Riverbend there are 135 people living in 47 homes which equates to 2.872 people per dwelling unit. Using this density at total build out of all 68 units, both existing and proposed , at 80 gallons per person per day equates to a total flow of 15624 gallons per day or 78 percent of permitted flow. There is an additional 5550 gallons per day designed into the system. However, this additional volume would need to be reviewed and confirmed by the Colorado Depariment of Health prior to exceeding the flows defined in the current discharge permit.

FACIUNES EVALUANON V, w. C. Treatment Facility (hntinued): The evaluation on the previous page shows thar thefaciliy, is capable of treating Ig,gS0 gpd and 33 tbsBoDt/day. These are the capacities approvedfor thefacility untder siri opprouil #4134. The hydraulic capaciry of 0.01995 MGD will apply to Part I, Section 8.2. of the generil permit and wilt also be the effluent flow limit for the facitiry. D. Biosolids Treatmcnt and Dbposal: Since the treatmentfacility consbts of aerated lagoons, biosolids removal witt probabty be infrequent (once every 5 to I0 years) and only take place if the ponds are drained and cleaned. If biosotids are removed from the lagoons for any reason ihey must be tlisposed of in accordance with local, State and Federal regulations. E. Indwtrial Wasrc Management Requirements Due to the lack of identfied industrial users in the se.rvicc arca, and thefact that the perminee does not accept hazardous wastefor ffeatrnent, the permittee Lr not requircd to mttintain aformal pretreatnuntprogram Howevar, standard industrial waste nwnagement conditions will apply as described in the general permit. F. Wole Effluent Toxicity Testing @ionanitoring) Based upon the lack of identified industial users and a review of other available information, and pursuantto the aquatic life biomonitoring requirem.ents in Secrion 6.9.2(2)(a)of the "Regulationsfor the SrateDischarge Permit System", 6. 1.0, the Division does notfntl that thcre is a reasonable potentialfor v,,hole efflueru toxicity @ED in the efrluent. Therefore, biomonitoring will not be a requiremcnt of the permit ar this time. PERFORMANCE HISTORY Since this is a newfacility, no performancc history is available for con-sidcration.

CONFORMANCE WITTT CERNFICANON REQUIREMENTS E' As discussed in section III-A-2 of this certfication, there are no control regulations that would limit thedbcharge of nirrogen or phosphorus Vom rnx pcitiry ana thb dbcharge should not cause any viotations ofdownstream sffeam standards, thus mceting the requirements of Part i, sections A.3.e and h of the generalpermit' As further proof that no water qualiry standards witt be uiolated, assumptioru made in therationale for the general permit for the fottowing parameters have been verified. ' 1' Fecql coliform Bacteria: The average "background" fecal cotform bacteria concentration tisted inTable III-2 is 89 organisms per 100 nn, which es /ess than the maximum attowable hackgroundfecatcoliform concentration identfied in section Iv.A.3 of the raionalefor the general permit. 2' Total Rgsidual chlorine: The instream toml resi.dual chlorine eRC) conccntration in the ColoradoRivcr above the facitiry is assumed to bt zero because of the large flow in the river and the rapiddissipation of TRC in well aerated streams. Therefore, in, ^ruipiions regarding the backgroundresidual chlorine concentration made in section IV.A.3 of the rationate foi the gineral p"rtri or"valil. 3' Total Ammonia: Table IV-3 in section Iv.A.3 of the rationalefor the general permb indbaes thatinstream total anvnonia concentrations ma$ be below 0.3 mg/i during"the most critical months in orderto prote$ the unionked anvnonia standard of 0.02 mg/t. In order ti verfy that thb concentration isnot uceeded, assuming a l0o:l dilution ratio and an efrluent totat ammoiia concentraion of 25 mg/t,the rationale for the general permit requires that the ,r*r^u^ background total atrunoniaconcentration cannd uceed 0.05 mg/l during this critical pariod. Tha monthly average ,,background,, total ammonia concentrations listed in Tablc I I I -2 of this rationala are all less' than o-"05 mg/t. Sincethe "background" total ammonia levels do not etceed the identifi.ed concentrations, the requiremens ofthe rationale for the general permit have been met. since the dilution ratio lbted above is muchgreater than 100:r, no ammonia rimit or sampring witt be required. ' F' Thb facility does not accept' by rruck, rail, or dedicated pipetine, any hazardous waste for treatmznt anddischarge thus meeting the requirement of Pan I, section A.3.g of the general permit. Based on the information presented in sections I through v of this cenification, as summarized above, thefaciliry mcets the requircmentsfor ccnification as dcliieated at parr l, secrion A.3 of the general permit.

If the 25 mgll limit can be nut, the permit writer will compare truruhly background conccntratians, above the dbcharge point, to the values listed above and cenifrcation will be attowed where no actual monrtIy background values sceed rte allowable background value. If there are one or nnre montls where the background concentration exceeds the listed value, then the DivLsian will determine if the ditation ratio for that month b greater than 1N:1. If the ratio is greater than 100:1, then the Division will calculate the albwable background concentration based on the actual ruio and compare thot value to the actual concentration. And, f the calculated value is greater than the actual value, thefacility wiV be cmifiedfor coverage under the general permit. Where there are no data that can be used to estabtish a background total orunonia concentration above the dischuge point, the Division will norrnatty assun'E a background concentration of zero unlesS there k a source of total atrunonia within one to three miles upstrean of the applicant's dbcharge.point. In cases where there are adequate data to run the CAM, the Division witt do so onty if the faciliry cannot be cenified using one of the above described methods- coLoRADo DEPARTMENT oF HE/4L,,I, water auaby bntrol DivisbnRationalc - Pagc 7, pemit No. COCTSS4dOO N.
