The property is located approximately 5 miles due east of the city of Glenwood Springs. The majority of the property is tributary to the Roaring Fork River basin via Red Canyon Creek and Cattle Creek. A small portion of the property along the northern boundary is tributary to the Colorado River through Glenwood Canyon. The property is accessed via Garfield County Road 114, commonly known as the Colorado Mountain College (CMC) Road. The property borders federal lands to the north and west of the property. The majority of the northern boundary of the property borders the White River National Forest, and the majority of the western boundary of the property borders Bureau of Land Management (BLM) property. Along the southern and eastern boundaries the property borders other private lands. The proposed development improvements in the area analyzed include the following: 1. The development of a residential community consisting of primarily single-family structures. 2. The development of a community village center including a restaurant, fire station, Metro District buildings, general store, post office, community meeting facilities, and other associated structures. 3. The development of 2 18 -hole world-class golf courses, and various other recreational amenities and associated structures. 4. The construction of the development infrastructure necessary to serve the proposed community including roads, trails, utility systems, and drainage infrastructure. PREVIOUS DRAINAGE STUDIES Gamba & Associates, Inc. (G&A) has prepared a previous drainage study for this property, dated December 21, 2000. The previous study was prepared for the PUD/Subdivision Preliminary development plan. The scope of this current drainage study is specifically limited to the improvements proposed for Phase 1. Spring Valley Ranch PUD - Final Plan Drainage Study October 15, 2007 Page 3 of 9 • HYDROLOGIC AREA For this analysis, we have delineated 3 separate primary tributary drainage basins. The pre -development boundaries for the tributary drainage basins are depicted on Pre - Developed Drainage Map. Post Developed drainage basins are often further divided into areas tributary to each individual culvert, then routed into a stormwater basin, or routed into an area that bypasses the basin. The post -development boundaries of the tributary drainage basins (tributary areas) are also depicted in greater detail in the Drainage Plan Set (D Sheets) included in the Spring Valley Ranch P.U.D. Exhibit 26. HYDROLOGIC CRITERIA AND METHODOLOGY Runoff flows for the different basins were calculated using the U.S. Department of Agriculture Soil Conservation Service Technical Release No. 20 methodology. The hydrologic calculations, reach attenuation calculations, and detention pond routing analysis calculations were performed with the HydroCAD release 8.00 software by HydroCAD Software Solutions LLC. The following data and calculations for both pre - development and post -development conditions for each of the 3 drainage basins are provided in the appendices: • Rainfall values • Drainage basin (watershed) areas • Hydrologic curve numbers • Times of concentrations • Travel time • Peak discharges • Calculated hydrographs for the pre -development conditions • Calculated hydrographs and proposed mitigation for post -development conditions The rate of runoff for 100 -year design frequency storm events were computed using the rain fall values for the Type 11 storm from the NOAA Atlas 2, Precipitation Frequency Atlas of the Western United States, Volume III -Colorado 1973. The Hydrologic Curve Numbers (HCN) for this analysis were determined from the best available information. HCN's are based on two factors, the hydrological soil type and the ground cover. For this analysis the hydrologic soil types (A, B, C or D) were determined from the U.S. Soil Conservation Service (SCS) naps of the specific area. The determination of the ground cover during pre -development conditions was based on the vegetation cover for the site, which was mapped by a botanist based on an on-site survey. The vegetation map for the site is included separately in the preliminary plan submittal. The ground cover for post -development conditions was modified from the pre - development conditions by incorporating the affects of the development, including roads, structures, golf courses, etc. Spring Valley Ranch PUD - Final Plan Drainage Study October 15, 2007 Page 4 of 9 • • The T.R. 20 method requires the calculation of the times of concentration (Tc) of each basin and a subsequent travel time (Tt) from the basin outfall to the composite watershed outfall point. The Tc for each basin is calculated based on the type of flow, and the length, grade, roughness and geometry of the flowpath of the overland flow from the hydraulically most distant point in the basin to the outfall point. The overland flows for each sub area were broken into three categories of flow types as they applied to each specific basin. The three flow types are sheet flow, shallow concentrated flow, and channel flow. The individual calculations for the times of concentration based on the various flow types are provided for all basins and storm events in the appendices. Based on the input of the rainfall values, the drainage basin areas, hydrologic curve numbers, times of concentration and travel time, the computer model calculates a hydrograph providing the calculated rates of stormwater runoff over a specific time period. The computer model also calculates the peak rate of runoff. The rainfall values, drainage basin areas, hydrologic curve numbers, times of concentrations, travel times, peak discharges, and the calculated hydrographs for pre- development conditions are provided in Appendix A. POST -DEVELOPMENT HYDROLOGIC CALCULATIONS AND MITIGATION OF PEAK RATE OF RUNOFF Methods similar to pre -development are used for post -development analysis. The boundaries of the post -development tributary areas (watersheds) differ from the pre - development tributary area boundaries due to the capture and diversion of certain areas based on the development infrastructure such as roads, driveways and structures. Also as briefly described above, in some instances, the post development tributary areas (watersheds) have been further divided compared to the pre -development analysis. In areas where stormwater detention basins are proposed to mitigate runoff, the pre - development watersheds are divided into areas tributary to the detention basin and areas bypassing the detention basin. Hydrographs are calculated for each sub -area, and then are combined at the watershed outfall point. The post -development Hydrologic Curve Numbers (HCN) were determined from the hydrological soil type and the post -development ground cover. The ground cover for post -development conditions was modified from the pre -development conditions by incorporating the affects of the development, including roads, driveways, structures, golf courses, etc. The following assumptions for impervious area and irrigated lawn area for each lot within a particular zone district have been used in this analysis for the determination of the post -development HCWs: • Golf Lots: 9,800 s.f. impervious area 4000 s.f. irrigated lawn Spring Valley Ranch PUD - Fina! Plan Drainage Study October 15, 2007 Page 5 of 9 • • • The post -development ground cover conditions for all other areas of development were based on site specific estimates of the proposed future development. The post -development Tc for each basin was calculated based on the type of flow, length, grade, roughness and geometry of the anticipated post -developed flowpath of the overland flow from the hydraulically most distant point in the basin to the outfall point. The individual calculations for the times of concentration based on the various flow types are provided for all basins and storm events in the appendices. Reaches are then applied to each culvert outfall to model additional Tc. These reaches are intended to model actual flow times from culvert outfall to the next downstream structure. Again, based on the input of the post -development hydrologic data, the computer model calculates a hydrograph as well as the peak rate of runoff. The hydrologic input data as well as the calculated results for the post -development conditions are provided in Appendix A. The post -developed peak rates of runoff were mitigated on site via several different methods. The typical method for mitigating peak discharge is through the development of stormwater detention basins. These detention basins detain the increased post - development peak discharges and release stormwater flows at a rate intended to model pre -development conditions. This method is proposed in all watersheds with the exception of Basin 0. The rainfall values, drainage basin areas, hydrologic curve numbers, times of concentrations, travel times, reach geometry, peak discharges, and the calculated hydrographs for post -development conditions are provided in Appendix A. ANALYSIS RESULTS Following are the resulting calculations for the pre -development peak rates of flow for each watershed and the mitigated post -development flows for the 100 -year storm event. Watershed or Tributary- Area Pre- Development Area (Acres) Pre -Development Peak Flow from the 100 -Year Storm (CFS) Post- Development Area (Acres) Post -Development Peak Flow from the 100 -Year Storm (CFS) Area -A 1623.01 165.32 1615.019 120.06 Area -O 107.974 21.50 1 107.038 7.12 Area -P-1 228.69 20.62 231.783 20.49 Table 1 Spring Valley Ranch PUD — Final Plan Drainage Study October 15, 2007 Page 6 of 9 • • As shown in Table 1 the proposed detention basins effectively mitigate flows for area A and P-1. In Basin 0 there is a minimal increase in impervious area and routing the storms to each individual drainage culvert effectively lowers the peak. Since the peaks from this drainage basin arrive at the outfall point defined in pre -development at different intervals the effective 100 year flow is mitigated through storm water routing rather than through a detention pond. A proposed detention pond in Basin 0 will be constructed when there is further development in Basin 0 for future construction phases. A potential debris flow hazard area has been identified on 2 areas of the site. Both areas are delineated in Appendix B, they were designed with flows calculated for the final build out of all phases. The northerly of the two Debris Flow A-1, causes no impact to building envelopes, or infrastructure. If a debris flow were to happen it could be cleaned from the road without causing any damage. Debris Flow A-2 required careful planning to avoid impact to lots. Easements and envelope restrictions were used to ensure channel flows did not impact building envelopes. The channel sections in Appendix B illustrate the minimum 58.74 sf calculated cross-sectional flow area. This cross-sectional area will provide adequate channel capacity to convey the potential debris flow from the 100 yr. storm having a maximum debris flow velocity of 2 feet per second (fps). At velocities below 2 fps debris will effectively settle out of the flow thereby eliminating any potential hazard. PROPOSED STORMWATER QUALITY MITIGATION Appropriate erosion control measures and Best Management Practices (BMP's) will be incorporated into the development plan and employed throughout the development process in order to appropriately mitigate the quality of stormwater runoff. As required by the Colorado Department of Public Health and Environment, Storm Water Management Plans will be prepared prior to the commencement of each phase of construction. CONCLUSION These hydrologic calculations demonstrate that the post -development peak rates of runoff for the 100 -year storm event can be mitigated to levels below the pre -development conditions for the Spring Valley Ranch PUD by constructing the storm water mitigation measures as proposed herein.
