GENERAL LOCATION AND DESCRIPTION 1.1 Location The Harmony Technology Park – 6th Filing is located in the Northwest Quarter of Section 4, Township 6 North, Range 68 West of the Sixth Principal Meridian, in the City of Fort Collins, Larimer County, Colorado. Please refer to the vicinity map in Appendix A. The project site is located at the southwest corner of E. Harmony Road and Lady Moon Drive. Lady Moon Drive bounds the property on the east, E. Harmony Road on the north, a vacant parcel on the west and Timberwood Drive on the south. The Harmony Technology Park – 6th Filing development consists of Lots 1 through 6 and is a replat of Lot One, Harmony Technology Park Second Filing. 1.2 Description of Property The property consists of about 9.2 acres of land and will be constructed in two phases. The first phase (Lots 3, 4 and 5) will consist of three new buildings and new parking and drive aisles. The second phase (Lots 1, 2 and 6) will also consist of three new buildings and additional parking and drive aisles. This report is specific to the design of Lots 3, 4 and 5 which are the only lots included in the current Project Development Plan. The site generally slopes in an easterly direction at approximately 0.5% to 1.0%. The land is currently vacant. Offsite flow contributes to the site from the adjacent south half of Harmony Road and the adjacent full width of Lady Moon Drive. According to FEMA Panel 08069C0994F there are no mapped FEMA Floodways on this property. 1.3 Floodplain Submittal Requirements Because the project is not within any FEMA or City of Fort Collins mapped floodway, a Floodplain Submittal is not required and a “City of Fort Collins Floodplain Review Checklist for 50% Submittals” has not been included with this report. 2 2. DRAINAGE BASINS AND SUB-BASINS 2.1 Major Basin Description The proposed development lies within the McClellands Basin and McClellands Creek Master Drainage Plan. The overall development has been designed with a master plan by Stantec Consulting, Inc. and titled “Final Drainage and Erosion Control Study Harmony Technology Park Site Master Plan”, dated May 19, 2008. 2.2 Sub-basin Description Historically, the site generally drains to the storm system in Lady Moon and eventually reaches the Fossil Creek Reservoir Inlet Ditch (FCRID). 3. DRAINAGE DESIGN CRITERIA 3.1 Regulations This report was prepared to meet or exceed the “City of Fort Collins Storm Drainage Design Criteria Manual” specifications. Where applicable, the criteria established in the “Urban Storm Drainage Criteria Manual” (UDFCD), developed by the Denver Regional Council of Governments, has been used. 3.2 Directly Connected Impervious Area (DCIA) Discussion Urban Drainage and Flood Control District (UDFCD) recommends a Four Step Process for receiving water protection that focuses on reducing runoff volumes, treating the water quality capture volume (WQCV), stabilizing drainageways and implementing long-term source controls. The Four Step Process applies to the management of smaller, frequently occurring events. Step 1: Employ Runoff Reduction Practices To reduce runoff peaks, volumes, and pollutant loads from urbanizing areas, implement Low Impact Development (LID) strategies, including Minimizing Directly Connected Impervious Areas (MDCIA). 3 Runoff for the northern portion adjacent to Harmony Road will be routed through vegetated areas through sheet flow thereby reducing runoff from impervious surfaces over permeable areas to slow runoff and increase the time of concentration and promote infiltration. Runoff for the eastern portion adjacent to Lady Moon Drive will be routed through three bioswales thereby reducing runoff from impervious surfaces over permeable areas to slow runoff and increase the time of concentration and promote infiltration. Runoff from the parking lots and surrounding sidewalks shall drain directly into porous pavement systems thereby slowing runoff and also promoting infiltration Step 2: Implement BMPs that Provide a Water Quality Capture Volume with Slow Release Once runoff has been minimized, the remaining runoff shall be treated through the porous pavement system. The porous pavement system allows for settlement of sediments. Step 3: Stabilize Drainageways Natural Drainageways are subject to bed and bank erosion due to increases in frequency, duration, rate and volume of runoff during and following development. Because the site will drain to a master planned regional water quality and detention pond, bank stabilization is unnecessary with this project. Step 4: Implement Site Specific and Other Source Control BMPs Proactively controlling pollutants at their source by preventing pollution rather than removing contaminants once they have entered the stormwater system or receiving waters is important when protecting storm systems and receiving waters. This can be accomplished through site specific needs such as construction site runoff control, post- construction runoff control and pollution prevention / good housekeeping. It will be the responsibility of the contractor to develop a procedural best management practice for the site. 3.3 Development Criteria Reference and Constraints The runoff from this site has been routed to conform to the requirements of the City Stormwater Department and the approved Harmony Tech Park drainage plan. Because water quality capture volume from this site will be provided for in the downstream regional detention and water quality pond 301, water quality facilities are not required for the site. However, City LID requirements are necessary therefore; additional water 4 quality will be accomplished through the use of the porous pavement systems that include 12” of storage in the voids below the pavers and bioswales located along Lady Moon Drive. The impervious area for the site has also already been accounted for in Pond 301 and was assumed to have a C value of 0.80 and an impervious value of 80%. Please refer to supporting documentation in Appendix E. Runoff reduction practices (LID techniques) are also required. No less than fifty percent of any newly added impervious area must be treated using one or a combination of LID techniques. The project adds 177,583 sf of new impervious area. Using the porous paver LID technique, 103,457 sf of new impervious area (58%) will be treated which exceeds the 50% requirement. No less than twenty five percent of any newly added pavement areas must be treated using a permeable pavement technology. The project adds 106,822 sf of new pavement area. This project will incorporate 29,570 sf of porous pavers which is 28% of the newly added pavement which meets the required 25%. Please refer to Appendix D for LID calculations and information. 3.4 Hydrologic Criteria Runoff computations were prepared for the 10-year minor and 100-year major storm frequency utilizing the rational method. All hydrologic calculations associated with the basins are included in Appendix B of this report. Standard Form 8 (SF-8) provides time of concentration calculations for all sub- basins. Standard Form 9 (SF-9) provides a summary of the design flows for all Sub- basins and Design Points associated with this site. Water quality capture volume and detention has been provided for in the downstream regional detention and water quality pond 301. 5 3.5 Hydraulic Criteria All hydraulic calculations will be presented in the final drainage report and prepared in accordance with the City of Fort Collins Drainage Criteria. Preliminary StormCAD calculations are included in Appendix C of this report. Finalized hydraulic calculations will be presented in the final drainage report. 3.6 Floodplain Regulations Compliance The project is not within any FEMA or City of Fort Collins mapped floodway ; therefore, Floodplain Regulations Compliance is not required. 3.7 Modifications of Criteria The Master Plan basin cannot all reach Pond 301 at Lady Moon and Harmony. This area will free release and is discussed in the report. 4. DRAINAGE FACILITY DESIGN 4.1 General Concept The majority of the proposed development will be collected and conveyed to the proposed storm drain system via porous pavement systems before being under Timberwood Drive to Pond 301. Lady Moon and Harmony flows will be treated for water quality via bioswales before being released into the existing storm system in Lady Moon Drive. 4.2 Specific Details A summary of the drainage patterns within each basin is provided in the following paragraphs. Please refer to Appendix A for the drainage plan. 6 PROPOSED DEVELOPMENT (LOTS 3, 4 AND 5) Basins A and B are 0.56 and 0.81acres, respectively. They contain the parking lot on Lot 5. Basin A is calculated to have a 10-year discharge of 1.7 cfs and a 100-year discharge of 4.8 cfs. Flows from Basin A are captured by the porous paver system where the 100- year flow will be detained and reduced to 1.5 cfs. Basin B is calculated to have a 10-year discharge of 2.5 cfs and a 100-year discharge of 6.8 cfs. Flows from Basin B are also captured by the porous paver system where the 100-year flow will be detained and reduced to 3.2 cfs. An underdrain system will release this flow into the proposed storm system. This system releases into the east side of the existing double 5’x2’ box culvert under Timberwood Drive. This culvert directs flow south to Pond 301. Basin C is 0.19 acres, contains the western east-west drive aisle and is calculated to have a 10-year discharge of 0.7 cfs and a 100-year discharge of 1.7 cfs. Flows from Basin C are captured by proposed Type R inlets in the drive aisle that direct flow to the proposed storm system that releases to the existing double 5’x2’ box culvert under Timberwood Drive. Basin D is 0.45 acres and contains the Lot 5 building and eastern most portion of the east-west drive aisle. This basin has a 10-year discharge of 1.7 cfs and 4.5 cfs. Flows from the drive aisle will be captured in proposed Type R inlets in the drive aisle and the roof flow will be collected in roof drains. Both inlets and roof drains will drain to the same proposed storm system that releases into the existing double 5’x2’ box culvert under Timberwood Drive. Basins E and F are 0.99 and 0.83acres, respectively. They contain the north-south drive aisle and the parking lots on the south side of Lots 3 and 4. Basin E is calculated to have a 10-year discharge of 2.8 cfs and a 100-year discharge of 8.2 cfs. Flows from Basin E are captured by the porous paver system where the 100-year flow will be detained and reduced to 3.5 cfs. Basin F is calculated to have a 10-year discharge of 2.6 cfs and a 100- year discharge of 7.6 cfs. Flows from Basin F are also captured by the porous paver system where the 100-year flow will be detained and reduced to 2.5 cfs. An underdrain system will release this flow into the proposed storm system. This system releases into the existing double 5’x2’ box culvert under Timberwood Drive. This culvert directs flow south to Pond 301. 7 Basin G is 1.18 acres and contains buildings of Lots 3 and 4. This basin has a 10-year discharge of 2.9 cfs and 8.2 cfs. Flows from the buildings roofs will be collected in roof drains that will drain to the same proposed storm system that releases into the existing double 5’x2’ box culvert under Timberwood Drive. Basin H is 0.98 acres, contains the south half of Harmony Road adjacent to Lots 3 and 4 and is calculated to have a 10-year discharge of 2.7 cfs and a 100-year discharge of 7.7 cfs. Flows from Basin B are captured by the existing 24” flared end section which directs flow into the proposed storm system that releases into the existing double 5’x2’ box culvert under Timberwood Drive. FUTURE DEVELOPMENT (LOTS 1, 2 AND 6) The final design of the future development will occur when these projects submit a PDP. Basin I is 1.73 acres and has a 10-year discharge of 4.3 cfs and a 100-year discharge of 12.0 cfs. Basin I contains Lot 6’s building, the adjacent east-west drive aisle located to the north of the building and parking lot located to the south of the building. Flows from this basin will be collected in the building roof drains, Type R inlets proposed in the drive aisle and porous paver system that will all drain to a proposed storm system (future) that will release into the west side of the existing double 5’x2’ box culvert under Timberwood Drive. The porous paver system will reduce the 100-year flow to 7.0 cfs. Basin J is 1.39 acres and contains Lot 1’s parking lot and southern portion of Lot 1’s building and the southern portion of Lot 2’s parking lot. Basin J is calculated to have a 10-year discharge of 3.5 cfs and a 100-year discharge of 9.8 cfs. Flows from Basin J will be captured by the porous paver system where the 100-year flow will be detained and reduced to 5.0 cfs. An underdrain system will release this flow into the proposed storm system (future) that will release into the existing double 5’x2’ box culvert under Timberwood Drive. Basin K is 1.39 acres and contains Lot 2’s building and the northern portion of Lot 2’s parking lot and the northern portion of Lot 1’s building. Basin K is calculated to have a 10-year discharge of 3.2 cfs and a 100-year discharge of 8.8 cfs. Flows from Basin K will 8 be captured by the porous paver system where the 100-year flow will be detained and reduced to 7.0 cfs. An underdrain system will release this flow into the proposed storm system (future) that will release into the existing double 5’x2’ box culvert under Timberwood Drive. Basin L is 1.40 acres, contains the south half of Harmony Road adjacent to Outlot B and Lots 1 and 2 and is calculated to have a 10-year discharge of 2.8 cfs and a 100-year discharge of 7.2 cfs. Flows from Basin L are captured by the existing 24” flared end section that directs flow into the proposed storm system (future) that releases into the existing double 5’x2’ box culvert under Timberwood Drive. Today a temporary swale will be built to drain this area. Basin OS-1 is 1.87 acres. The majority of Basin OS-1 is the west half of Lady Moon Drive and is calculated to have a 10-year discharge of 3.9 cfs and a 100-year discharge of 10.8 cfs. Flows from a portion of this basin will sheet to bioswales located between the existing curb and gutter of Lady Moon and the proposed sidewalk. The bioswales will direct flow to existing Type R inlet and storm system located in Lady Moon Drive. Basin OS-1 is master planned to drain to Pond 301, but is physically lower than the pond and cannot drain there. Interwest worked with the City to study the capacity of the storm system in Lady Moon Drive from Harmony to Rock Creek and determined that 15 cfs of free release from this area could be achieved without flooding the system. Current design is for 10.8 cfs and therefore will not flood the system. See Appendix F for the offsite storm system study. The weighted average C value of the entire site is 0.67 which is below the Harmony Tech Park model assumption of 0.80; therefore, detention is not required on-site and is provided for in the regional Pond 301 located south of the site. Please refer to Appendix E for excerpts from the Harmony Tech Park design. 9 5. CONCLUSIONS 5.1 Compliance with Standards All computations that have been completed within this report are in compliance with the City of Fort Collins Storm Drainage Design Criteria Manual. 5.2 Drainage Concept The proposed drainage concepts presented in this report and on the construction plans adequately provides for stormwater quantity and quality treatment of proposed impervious areas. Conveyance elements have been designed to pass required flows and to minimize future maintenance. If, at the time of construction, groundwater is encountered, a Colorado Department of Health Construction Dewatering Permit will be required. 6. REFERENCES 1.
