III. PROJECT LOCATION AND DESCRIPTION A. PROJECT LOCATION The Project is located along State Highway 82 ("SH 82") between the City of Glenwood Springs and Town of Carbondale near the junction of County Road 110/113 ("CR 113") and SH 82. The property is located almost entirely west of the Roaring Fork Transit Authority ("RFTA") right-of-way and east of the Roaring Fork River and the Roaring Fork Conservancy ("RFC") Conservation Easement (i.e., Grant of Conservation Easement dated February 3, 2000, recorded at Reception Number 559036 and survey map, recorded December 24th, 2008, recorded at Reception Number 760571 in the real property records of Garfield County, Colorado). The Project straddles Cattle Creek which is also located within the RFC Conservation Easement. A vicinity map is provided as Exhibit 1 in Appendix A. The Project covers approximately 160 acres ("Project Site") as 5 Project Engineering Design Report River Edge Colorado, Garfield County, Colorado shown and described on the Project Site drawing [Exhibit 2(a -d), Appendix A]. The Project is proposed by Carbondale Investments, LLC ("CI"). B. PROJECT DESCRIPTION The Project is a proposal to create a walkable clustered -form of residential development with neighborhood amenities including naturalized open space and enhanced wildlife habitat, community recreation, parks, and neighborhood agriculture that is designed to serve the residents and preserve and provide reference to the rural character and agricultural roots of the Roaring Fork Valley. The Project aims to have a strong historic identity back to the days of 'old Colorado' when compact neighborhoods formed with a strong sense of community based on the land and surrounding landscape. The REC landscape aesthetic will be simple, informal, and place emphasis in the use of plant and landscape materials local, adaptable and appropriate to the climate and environment of the area. The Project will include approximately 366 residential units of various sizes and types including 55 affordable homes and one exclusive executive lot for a custom home. Housing types will range from attached homes to small single family attached and detached garden homes, village homes, and larger estate homes. Smaller garden homes are anticipated to be designed for younger residents that are looking for their first home in the County, while village homes and estate homes will provide move up opportunities for growing families. Densities in the Project are proposed at less than 2% units per acre. Lot sizes will vary from over 1 acre to approximately 5,000 square feet for single family homes, and 1,700-5000 square feet of lot area for each garden home. Most of the units back to either proposed active parks or reclaimed open space to help enhance the connection to the land. The REC layout and design is depicted in the PUD Plan, PUD01-03 Series and the Preliminary Plan PRPN01-03 Series of the Drawing Package. The architectural theme will be complementary to the traditional architecture of the valley. Generally, exterior materials will include wood, stone, brick, stucco and cement board siding. Varied roof heights and articulation of the front elevations will be used to break up the massing and provide street -level appeal. Front porches and covered stoops are included on homes to emphasize the entry and connection to the sidewalk and street. Roofing will include dimensional shingles, metal, or other materials appropriate to the building style and that roofs will generally be pitched. Gables, wall plane and roofline articulation, bays, balconies, porches, canopies and arcades will be used in the design of various buildings. The selection of materials will minimize the exterior maintenance of the homes to help maintain a quality appearance for the long term. The street pattern and pedestrian network are designed to facilitate community interaction. Streets have detached sidewalks with designated cross walks at major intersections and landscaped areas that create a comfortable environment for walking. On -street parking in most areas will further buffer vehicular and pedestrian uses. Internal circulation is maximized and dead-end streets are limited. Alleys are used where appropriate to enhance the streetscape and achieve a mix of housing styles. A soft trail system is used to connect open spaces and other common elements with the sidewalk network. The homes are placed close to the streets to help define the 6 Project Engineering Design Report River Edge Colorado, Garfield County, Colorado streetscape space and provide visual interest to pedestrians. Street trees and plantings are proposed to enhance the aesthetics of the street. The community is served with a variety of recreational facilities and a neighborhood center that could include meeting room(s), fitness room, offices, kitchen, restrooms, recreational facilities, and limited community service use such as a day care facility, deli/coffee shop, or health club. Parks will provide informal recreational opportunities within the community and will likely include tot lots, playfields, and trail system. The west portion of the property is generally set aside as the naturalized area that buffers the RFC Conservation Easement along the Roaring Fork River. The soft trails around the property allow residents to enjoy the river and wetland areas without disrupting the environment in conformance with the terms of the RFC Conservation Easement. More than the minimum open space requirements will be met by the project. Nearly 50% of the Project Site is in some form of open space, common area or park. Finally, opportunities for productive and edible landscapes, including community gardens and neighborhood orchards are integrated and dispersed in between the residential land uses as gathering and focal places for residents connecting REC to its agricultural heritage. The combination of trails, recreation areas, and open space system with the ability to engage in 'interactive community agriculture' on a small scale will make REC a very desirable place to live, filling a unique niche not yet met in Garfield County. This unique combination will help establish a sense of place, foster community, and engage residents with their immediate environment. It is intended this overall outdoor focus will set the tone and become a major driver of the identity of REC. IV. DESCRIPTION OF DESIGN AND CONSTRUCTION 1. SITE RECLAMATION (PHASE 0) Past development efforts that were prematurely terminated left the overall Project Site in poor condition as a result of extensive grading including substantial cut and fill areas and the removal of protective surface soils. Prior to initiating development activities, the Project Site must be reclaimed in order to address a variety of issues resulting from the degradation and land form changes associated with such previous activities. The Reclamation Plan (Appendix U of the Impact Report) details the proposed pre -development reclamation activates proposed for the Project Site that would be under taken as Phase 0 in advance of development construction. These activities are shown on the Series RPO1 of the Drawing Package and the post -reclamation conditions are shown on the Series ES02 of the Drawing Package. Where development - related actions are most appropriately taken at the time of reclamation and would result in limiting site disturbance and habitat impacts or alleviating safety issues and concerns, these actions are included in the proposed reclamation actions. Although site reclamation is proposed as a pre -development action, the development plans and drawings are based on existing conditions and not on Project Engineering Design Report River Edge Colorado, Garfield County, Colorado post -reclamation conditions. Final design must be coordinated with the post - reclamation conditions once these actions are completed. 2. ROADS Roads internal to the site were planned as continuous streets to provide for vehicular movement and facilitate mobility for other modes of travel with attached sidewalks and bike friendly speeds and sections. The residential areas are "clustered" with urban densities. Therefore, the standards used for street design were built based on the standards and framework provided by existing Garfield County road design standards contained in Section 7-307 of the ULUR, but were modified to meet Project objectives utilizing urban road design standards from several municipal jurisdictions in Colorado (i.e., most specially the City of Colorado Springs but also included a review of design standards in the City of Fort Collins and City of Denver), AASHTO and Neo -Traditional Street Design. The street sections adopted for use at REC are on shown on Typical Street and Trail Sections, C04 Series of the Drawing Package. The design criteria used for street layouts (Street Plan and Profiles, CO2 Series of the Drawing Package) are as presented in Table 1. The criteria are well within other jurisdictional standards for comparable development plans and meet the needs of the Carbondale Fire Protection District. In addition to vehicular movement, all the streets provide for on -street parking and detached sidewalks except alleys and courts.

The street hierarchy for the planned development consists primarily of two sections, Local and Alleys/Courts. Local streets provide site -wide mobility for homeowners and guests at a capacity that will exceed 5,000 vpd. The Local road 8 Project Engineering Design Report River Edge Colorado, Garfield County, Colorado section also allows for on -street parking on both sides of the street throughout all neighborhoods and direct access to all front loaded residential lots (driveway spacing is approximately 50 feet). Drainage will be controlled through the use of curb and gutters which direct flows toward storm sewer inlets. The Local street section was selected based on the planned character of the neighborhoods and level of safety expected for those using the street or interacting with it from the adjoining lots. Examples of similar urban streets can be found in Eagle Ranch, Town of Eagle, Eagle County, Colorado. Alleys/ Courts provide short connections between Local streets and access to rear loaded residential lots and garden homes (driveway spacing of less than 40 feet). The required minimum width of pavement for the Alleys/Courts sections is 20 feet per discussions with the Carbondale Fire Protection District. The Alleys/Courts section provides for 24 feet of pavement, Drainage will be controlled through the use of cross pans which direct flows toward the adjoining Local streets or adjacent drainageways. All lots directly access private streets that then access SH 82 via the main entrance at Cattle Creek Road. In addition to these two primary street sections, the entry road (River Edge Drive) is the approximately 500 foot street segment from the main access off SH 82 to the roundabout. The street section associated with this segment of road is adjusted throughout its length so as to coordinate with the highway access, RFTA right-of-way crossing, entrance to the neighborhood center and proper entry the roundabout. Detailed coordination on the entry road with CDOT and RFTA will be necessary during the final design process to ensure the design requirements of each agency are met Based on discussions with CDOT, it is anticipated that CDOT review will be threefold in accordance with the State Access Code. First, CI was required to complete a traffic assessment per requirements of Garfield County. Second, CI will be required to develop near and long term concepts to be used in discussions with affected agencies and land owners. Third, CI will be required to prepare a Level III Traffic Impact Report and final intersection design to support application for a CDOT Access Permit. In addition to the main access, two Emergency Vehicle Access (EVA) points have been discussed with CDOT, RFTA, and Carbondale Fire Protection District. The EVAs will be access - controlled to only allow for access during an emergency, no other access at these locations will be permitted. A roundabout is proposed at the main intersection internal to the development as a means of best accommodating traffic from the northern and southern areas of the Project. The roundabout is designed in accordance with standards from the City of Colorado Springs. The capacity for the roundabout will exceed 20,000 vehicles per day (vpd), with a peak hour capacity of 1,500. The preliminary design is provided on Roundabout Layout, CO3 Series of the Drawing Package. The preliminary design associated with road network is presented on the supporting drawings (Series C01 - C07 of the Drawing Package), 9 Project Engineering Design Report River Edge Colorado, Garfield County, Colorado 3. WATER AND WASTEWATER Onsite water and wastewater utilities are designed to support the planned development while considering future growth within the area outside Project. The overall layout of utilities generally mirrors the horizontal alignments of the streets. However, where appropriate the utility network was placed in easements outside paved street sections to create a more efficient and cost effective system. The RFWSD Rules and Regulations dated February 2007 were utilized as the primary source for design standards and criteria. The primary objective of the preliminary design was to consider the RFWSD standards in relationship to the site conditions and the planned development. In a vast majority of the situations the RFWSD standards can be met. However, there may be limited instances where the density of the "clustered" development may result in the need to vary from the RFWSD standards to achieve the design objectives. In these instances, the alternative standards will be coordinated with RFWSD to ensure the primary objectives for the water and wastewater systems are met. Based on the preliminary design, the only RFWSD standard not currently met was the minimum depth of flow within the sanitary sewer lines (i.e., 50 percent at peak flows). The minimum sanitary sewer line flow depth standard utilized by the RFWSD is somewhat unusual. The typical standard for depth of flow in pipes is focused on a maximum flow depth targeted at making sure the pipe is not pushed beyond its capacity when reaching peak flows. Therefore, the standard would typically be written as a maximum 50 -percent full during average flows and a maximum 80 -percent full during peak flows. Under the proposed standards, the system as planned will achieve the alternative standard of flow depth at the slopes, velocities, and pipe sizes presented. The preliminary design associated with water supply, treatment and distributions and sewage collection and disposal are described in detail in the Sewage Collection Report, Water Treatment and Distribution Design Report, Water Supply Plan and Sanitary Sewage Disposal Plan and supporting drawings (Series SW01 - SW04 of the Drawing Package). In addition to the planned water and sewage systems described above, the Project will provide raw water irrigation. The raw water will come from the Glenwood Ditch and be piped across the site via a community -owned and operated distribution system. This system is required under the water rights adjudications which will provide potable water. The Raw Water Supply and Distribution Plan and supporting drawings (Series SW05 of the Drawing Package) detail the preliminary design of the raw water system. 4. DRY UTILITIES Dry utility service provided by regional providers was also considered during the development of the preliminary design. Accessible and coordinated corridors for installation of these services have been planned for in the design and each 10 Project Engineering Design Report River Edge Colorado, Garfield County, Colorado provider has provided a "will serve" letter (Appendix B). Easements are provided along lot lines. Utilities are also accommodated in Right -of -Way Tracts 5. EROSION AND SEDIMENT CONTROL Under the Garfield County ULUR, the Erosion and Sediment Control Plan ("ESCP") is an all encompassing plan supporting grading, drainage, and surface water quality requirements. As such, the ESCP documents existing, reclaimed, phased and final conditions of the Project. In addition, the ESCP supports other plans such as the Reclamation Plan and the Hazard Mitigation Plan by defining how surface water is managed throughout the entire development process. As presented in the ESCP, the surface water quality and quantity is managed two ways utilizing the criteria from the USDCM. First, the runoff created by the development is limited by the design (i.e. reduced areas of imperviousness) and conveyed directly offsite to either Cattle Creek or the Roaring Fork River. Second, the "first flush" of surface water, which typically contains the highest concentration of contaminants, is treated via vegetated channels or through capture in one of three "water quality" ponds. No detention of storm water quantity volumes is proposed. The direct release of runoff from the Project Site without detention is discussed in detail in the ESCP. However, the two primary reasons behind this requested modification are that: (1) the site is low in the basin therefore releasing the runoff from the Project Site prior to the peak flows from other contributing basins upstream likely better limits the magnitude of the peak runoff condition downstream of the Project Site; (2) the direct release has no affect on any downstream properties or existing stormwater facilities. The preliminary design associated with the Erosion and Sediment Control Plan are detailed in the related report and supporting drawings (Series ES01 - ES05 of the Drawing Package). 6. DRAINAGE STRUCTURES Culverts and storm sewer were preliminarily located and culverts sized for the entire Project Site based on the overall drainage needs and design intent. The goal for stormwater management for the Project is to minimize storm water conveyance via piping and utilize open space areas to collect and convey storm water. Therefore, inlets located in road will immediately discharge to swales located in adjacent open space on much of the site. This approach provides two benefits. Discharging to grass swales will provide enhanced water quality prior to discharge to receiving waters (i.e. Cattle Creek and Roaring Fork River), and utilization of grass swales will provide increased travel time relative to conveyance via storm sewer pipe which servers to decrease peak flows and potentially reduces the size of major conveyance features. However there are three locations where it is anticipated that storm sewer will be needed due to the Project design constraints. 11 Project Engineering Design Report River Edge Colorado, Garfield County, Colorado For preliminary analysis, storm sewers were sized and designed in three locations. There is one storm sewer system on the north portion of the Project and two on the south. The northern system captures the main drainage channel that drains much of the north portion of the project (Basin P2) as well as the offsite basin to the east (Basin OS -1) and discharges to Pond NP2. Therefore, a more detailed preliminary analysis was conducted on this system to ensure the system could accommodate the anticipated flows. A conservative 100 -year return period storm was used and the results of this analysis are shown in Appendix C. A more basic analysis was conducted for the other two systems as these are minor in nature. The Riverside Loop Drive system has a capacity of 100 cfs and an anticipated 100 -year flow of 12 cfs. The Alpine Bluff Street system has a capacity of 100 cfs and an anticipated 100 -year flow of 20 cfs. A preliminary layout of all these systems can be found in Series DR01-03 of the Drawing Package. Preliminary calculations for culvert sizing were also completed along all drainage channels and can be found in Appendix C. Preliminary sizing of the culverts was done in accordance with the USDCM methodology. The stage -discharge relationship and entrance and exit head loss given the configuration of the culvert are provided. For each stage, a maximum flow rate for both inlet control and outlet control is calculated. A manning's "n" of 0.013 was used for all culverts. Slopes were estimated based on the current over -lot grading plan and minimum cover was assumed to be 18 -inches when underneath a road. Material for all culverts is preliminarily proposed as concrete and pipe class will be determined at final design based on estimated loading.

Opening and backfilling of trench, should Qwest miss the advanced notice of open trench 4. LDA COSTS A. UP TO $528.40 per lot allowed towards construction costs B. Developer, prior to cable placement, must pay charges above $528.40 per lot. C. Qwest will reimburse to the developer $79.77 per lot for the cost of opening trench and backfill, if the construction costs are less than $528.40 per lot. D. Qwest will not reimburse to the developer more than the $528.40 per lot. App. B-7 E. Allotted standard placing crew mobilizations. a. 1 to 50 lots = 2 trips to complete cable placement 51 to 100 lots = 3 trips to complete cable placement 100 to 150 Lots = 4 trips to complete cable placement 150+ lots = 5 trips to complete cable placement b. Allotted trips based upon documented averages for placing cable in above mentioned various size subdivisions plus 1 additional day. c. Additional trips to site due to developer not having entire trench available or power company requirements that the trench be closed daily that require excessive mobilizations may be billed to developer at actual labor costs. App. B-8 GENERAL INFORMATION 1. Call us in advance Call when you have a preliminary plat, especially if your project is the first filing in an undeveloped area. Placing cable in your subdivision is only one part of providing telephone facilities. We may need to place additional facilities and equipment, requiring many weeks of planning design and construction. 2. Meet with us face-to-face Our local Field Engineer should discuss your plans in detail and resolve any issues with a face-to-face meeting. This is essential for a large, phased project. 3. Joint trench—It's your responsibility QWEST requires (BY THE TARIFF) the developer to provide trench for telephone cable either by sole trench or joint trench. If the trench is to be joint (provided by the power company), it is the developers responsibility to schedule a mutually agreeable date for that trench opening 2 weeks prior, and to maintain control of the closing of that trench per the terms and conditions of section 4D of the LDA agreement. If the developer provided trench places our cable out of easement, it is the developers FINANCIAL RESPONSIBILITY to have the cable relocated, spliced and paid for the cost of the material. Many power companies are adopting a close trench daily policy. This policy does not adhere to the terms of the section 4D of the LDA agreement and is not acceptable to QWEST. We will make reasonable attempts to place cable under these circumstances, however, our crews must visit many developments on a daily basis and are not obligated to visit your site every day. Any trenches missed due to power company close daily policy must be reopened by the developer at his expense. If you wish to have a crew on your site full time on a daily basis, you will be required to contact the local coordinator in advance to arrange for billing of labor costs over standard construction intervals (identified above). These costs normally will run $300 to $500 per day depending upon the location of your development until construction is complete. App. B-9 GENERAL REQUIREMENTS (CONTINUED) 4. Schedule your trench well in advance. Call your area coordinator at least 30 days from anticipated trench opening to allow time for material ordering and to insure availability of a construction crew to place cable. 5. Pre -construction Meetings It is MANDATORY to schedule a pre -construction meeting 1-2 weeks in advance of the trench opening. This is a good opportunity to address final scheduling and trenching issues or other problems that may arise, such as walls, gates, landscaping, etc. 6. Trench Opening Call us a few days in advance of actual trench opening to confirm that material is on hand and a crew is scheduled to be on site when the trench is opened. Please call us when the trench date is changed so that a crew is not mobilized unnecessarily to the site when no trench is open and ready. 7. Final Grade Be very certain that the subdivision is within 6 inches of final grade before opening the trench. Developer will billed full costs if we are required to raise or lower cable or pedestals due to grade change. S. Easements In addition to the 8' to 10' utility easement provided on the plats for cable placement, we may require a pocket easement for our equipment. Sizes may vary from 10' X 20' to 30' X 30'. If it is discovered that our cable is out of easement after it has been placed, the developer is responsible for providing a new trench and pay any costs associated with placing the cable in correct easements. App. B-10 GENERAL REQUIREMENTS (CONTINUED) 9. Addresses — Why are they so important? The homeowner will not get telephone service without an address. Addresses are built into our database for telephone assignment of the customer's service order. An Address Plat is required for this purpose and the developer is responsible for well in advance to avoid delays in pre -provisioning a home and have dial tone available when a homeowner moves in. 10. Road Crossings A 4" (four inch) Schedule 40 PVC conduit is required for road crossings. Do not rely totally on the power prints to determine road crossing for Qwest. Sometimes we will need additional crossings where the power company is not going. Please call if you are ready to place road crossings and do not have a job print. Crossings can generally be decided in advance of final job prints. 11. Trenches The developer is required to provide all joint use and sole trench. Maintain a 30' to 36' minimum trench depth for cable. Grade is to be within 6" of final at time of cable placement. Provide backfill which shall consist of sound earth material, which contains no rocks larger than 1". Backfill shall be free from concrete, lumber, asphalt, metal, vegetation, or other debris. If cable damage occurs from objects in the backfill, the developer will be billed for damages.
