SECTION 4 Wooloerl, Inc. Packwood West-Carmel, IN August 2007 Duke Realty, LP DRAINAGE SUMMARY Project Description This project consists of the construction of the second phase of the overall Parkwood West development plan. Two previous drainage plans have been approved by the City of Carmel; the Parkwood West Master Plan (March 2001), and the Parkwood West Master Plan -Supplement (May 2006), which incorporated new City of Carmel Stormwater requirements that were introduced after 2001, for the purpose of approving the construction of Phase 1 of the project. The purpose of this drainage plan is to show 1.) Phase 2 storm sewer calculations, and 2.) that the overall drainage, with the construction of Phase 2, functions as designed in the master plan. Proposed Conditions In the 2006 report, the master drainage plan was revised to provide adual-stage outlet structure for the previously designed underground detention system to provide restricted release rates for both 10 and 100-year storm events. This was modeled with the ICPR3 design software program. Release rates from the detention system for the 10 and 100-year storm events were 6.40 and 9.08 cfs, respectively, as shown in Table 1. For the design of Phase 2, the same seven drainage basins of the overall site were analyzed, however the basin limits were adjusted slightly to fit the drainage patterns of the Phase 2 design. Drainage calculations for the Phase 2 plan are provided in Section 2 of this report. The resulting release rates, which are equal or less than the master plan rates, are also shown in Table 1. Table 1. Overall Site Stormwater Release Rates 10-Year Discharge, Qto 100-Year Discharge, Qtee Master Drainage Plan (2006) 6.40 cfs 9.08 cfs Phase 2 Drainage Plan (2007) 6.38 cfs 9.08 cfs Also as part of revised Stormwater requirements, an Aqua-Swirl AS-8 was proposed as part of the 2006 Master Plan Supplement to provide an adequate stonnwater treatment BMP. During construction the City of Carmel approved the substitution of the Aqua-Swirl with a Vortechs 7000 BMP unit. With no additional flow from the detention system, this unit will continue to provide adequate Stormwater treatment for the overall site. The Phase 2 storm sewer was designed fora 10-year storm event using Indianapolis 1DF curves. Calculations were prepared using FlydraFlow Storm Sewer software, and are included in Section 3 of this report. Woolpert, Inc. Parkwood West-Carmel, IN August 2007 Duke Realty, LP Conclusion The plan for Phase 2 complies with the original Master Plan for the overall Parkwood West development. The underground stormwater detention system will release at or below the original designed rate for both 10 and 100-year storm events. No other deviations from the master drainage plan occur with proposed Phase 2 of this development. Woolpert, Inc.
