The development contains 5 commercial lots encompassing 8.8 acres. The development infrastructure was designed and constructed in 2019 and the existing detention basin and stormwater BMP design presented in the Final Drainage Report for Monument Marketplace North Filing No 1 by WestWorks Engineering, referred to as the WestWorks Drainage Report. This Drainage Report for the Panda Express is an analysis of the existing development and detention basin with a focus on the Panda Express development. An aerial photo is shown in Appendix A. DRAINAGE CRITERIA The Town of Monument and Colorado Springs drainage criteria was used for the basis of this analysis. The drainage criteria requires that the discharges expected from post-construction of the site should be the same or less than that of pre-construction condition for the 5 and 100 year storm events. The detention pond designed for this development should convey the runoff from all storms up to the 100 year storm and provide a minimum of 1 foot of freeboard. An emergency overflow route is required to be capable of conveying the 100 year storm in the event that the primary outlet is totally clogged. RAINFALL DATA The 24-hour total rainfall depths were used for all storm events. These depths were used in accordance with the City of Colorado Springs Design Criteria Manual. The SCS Type II rainfall distribution was used to model the storms, with the total rainfall depths as provided in the following table. RAINFALL DATA STORM FREQUENCY TOTAL RAINFALL DEPTH (IN) 5 Year (20%) 2.68 100 Year 5.45 EXISTING CONDITIONS The existing conditions considered for this report are the pre-development conditions presented in the WestWorks Drainage Report. The undeveloped site is grass covered with two existing storm drainage lines that bring runoff from the east side of Jakson Creek Pkwy. These two storm systems are not a part of this analysis. The site slopes from northeast to southwest to an existing wetlands boundary southwest of the development. The Point of Analysis is the location where the site flows into the wetland boundary. The drainage area is shown in the existing drainage map in Appendix F. The FEMA map is shown in Appendix A. ---PAGE BREAK--- Panda Express 16481 Cinematic View, Monument, CO Drainage Report Page 2 The El Paso County Soil Survey on the USDA website shows the existing soils to primarily belong to hydrologic soil group as shown in Appendix B. The Modified Rational method was used for runoff using runoff coefficients as listed in Table 6.6 of the City of Colorado Springs Drainage Criteria Manual, Vol 1. There were no existing impervious areas on site. The Time of Concentration, Tc, was calculated using the NRCS – TR55 method. The runoff coefficient and Time of Concentration used for existing conditions are shown in Appendix C. Bentley’s PondPack software package was used to determine flows from the site. PondPack used the NRSC – TR55 and Modified Rational hydrograph methodology to analyze the site. The PondPack results for the existing conditions can be seen in Appendix C. Existing Areas: The existing site consists of 8.8 acres of undeveloped pasture and meadow land. Existing flows: STORM EVENT TOTAL EXISTING RUNOFF TO POA-1 (CFS) 5 Year (20%) 9.89 100 Year 20.26 DEVELOPED CONDITIONS Full Development: The Monument Marketplace North, Filing No. 1A development consists of 5 commercial lots planned for commercial buildings with drives and parking lots along with the private street, Cinematic View Drive. The development is designed with a storm drainage system to collect the runoff and convey it to the detention basin in Tract A6. Refer to the Site Construction Documents by Westworks Engineering in Appendix F. The storm drainage systems from the east side of Jackson Creek Pkwy are extended through the development and not routed to the detention basin. The overall runoff coefficient for the development is C(5) 0.81 and C (100) 0.88. The proposed flow patterns are shown on the Proposed Drainage Map in Appendix F. The existing detention pond was designed to reduce the total runoff at the point of analysis to pre- development levels for the 5 yr and 100 yr storm events. Note that the development releases runoff directly into an existing wetland boundary that is not part of this plan or analysis. Lot 5A - Panda Express: The proposed Panda Express is located on the 1.08 acre Lot 5A. The Panda Express development includes a 2600 sf building with drives and parking lot resulting in 39,622 sf of impervious area. The lot is 84% impervious. A runoff coefficient of 0.81 and 0.88 are used for the 5 year and 100 year analysis respectively. ---PAGE BREAK--- Panda Express 16481 Cinematic View, Monument, CO Drainage Report Page 3 The El Paso County Soil Survey on the USDA website shows the existing soils to primarily belong to hydrologic soil group as shown in Appendix B. The Modified Rational method was used for runoff using runoff coefficients as listed in Table 6.6 of the City of Colorado Springs Drainage Criteria Manual, Vol 1. There were no existing impervious areas on site. The Time of Concentration, Tc, was the same as that used in the Waterworks Drainage Report. The runoff coefficient used for proposed conditions are shown in Appendix D. The PondPack results for the developed conditions can be seen in Appendix D. Proposed Areas: Lot 1 – 2.03 acres Lot 2 – 0.92 acres Lot 3 – 0.80 acres Lot 4A – 0.90 acres (Ziggi’s Coffee) Lot 5A – 1.08 acres (Panda Express lot) Tract A – 1.1 (detention pond) Harness Road and Cinematic View Drive – 1.97 acres Proposed flows: STORM EVENT TOTAL PROPOSED FLOW AT POA-1 (CFS) 5 Year (20%) 10.02 100 Year 36.66 EXISTING DETENTION DESIGN The existing detention pond is located on the west side of Cinematic View Dr within Tract A. The existing detention basin has a total volume of 54,145 cu ft. Refer to the Monument Market Place North Filing No. 1 Site Construction Drawings and Drainage Report by Westworks Engineering in Appendix F. The existing concrete outlet structure consists of a 21.27cu ft micro pool, a 35” x 35” outlet structure with a weir plate with 3 – 1-1/4” orifice for control of the water quality and smaller storm events, a 35” x 41” overflow into a secondary chamber with a restricted 18” outlet pipe. The three 1-1/4” orifice are at elevations 6894.0, 6895.84 and 6897.68, The overflow weir is at elevation, 6897.5. The flowline of the 18” pipe is 6891.50. Refer to the composite outlet structure information in Appendix E and the outlet structure detail in the Site Construction Drawings by Westworks Engineering. A 10’ wide emergency overflow weir is graded into the southern berm at elevation 6900.80. The maximum storage volume for the 100-year storm will be 35,321 cu ft at elevation 6900.41. For PondPack input/output regarding the detention pond and outlet structure, see Appendix E. The results for the proposed pond can be seen below. ---PAGE BREAK--- Panda Express 16481 Cinematic View, Monument, CO Drainage Report Page 4 Developed Pond Flows: STORM EVENT TOTAL DEVELOPED FLOW INTO POND (CFS) DETENTION POND RELEASE RATE (CFS) VOLUME DETAINED (CU-FT) PEAK STAGE ELEVATION (FT) 5 Year (20%) 9.89 2.54 27,726 6899.63 100 Year 36.66 21.84 37,646 6900.63 - Top of pond elevation at 6902.0 - Emergency Overflow Weir elevation at 6900.8 Existing Detention Pond Summary: The existing detention pond with outlet structure was designed by Westworks Engineering to control the runoff from the Monument Marketplace North Filing, No 1 development and release the runoff at predevelopment rates. The development of the Panda Express in Lot 5A meets the original design parameters keeping the basin functioning as originally designed. SUMMARY The existing detention basin meets the drainage criteria of the Town of Monument. The report documents that the developed condition, upon completion of site work, runoff from the Monument Marketplace North Filing, No1 is less than existing for the 5 and 100-year regulatory storm events. This development and detention pond will not have an adverse impact on the property to the south, as evidenced by the decrease in runoff at the point of analysis for all storm events.

Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long-duration storms. The soils in the United States are assigned to four groups B, C, and D) and three dual classes (A/D, B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink-swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes.
