A master stormwater management plan (MSWMP) for the entire Grand Avenue redevelopment area which governs the overall stormwater management of the Val-Gate district shall be prepared by the city of West Des Moines. Specific stormwater management plans (SWMP) will be required with the submittal of each site development plan. The specific stormwater plans shall be prepared at the developer's expense, by a professional engineer licensed in the state of Iowa. All specific stormwater management plans shall comply with the city's applicable design standards for stormwater management existing at the time each development (site plan) is approved. Said SWMP must demonstrate compliance with the Grand Avenue redevelopment master stormwater management plan, if available, at the time of site plan approval.
The developer(s) of the West Bank-Casey's PUD shall be required to participate in the Grand Avenue redevelopment stormwater management facilities per their pro rata share of stormwater contribution for the Val-Gate district.
Although it cannot be guaranteed, the city will attempt to structure the construction of stormwater infrastructure within the PUD parcels in such a manner as to minimize the impact on the business operations of West Bank and Casey's. Such mitigation measures may include limiting construction hours to nonbank hours and/or providing alternate means of access to the site (from north or west). Additional measures as identified may also be utilized. (Ord. 1945, 3-5-2012)
