A master stormwater management plan (MSWMP) for the entire Grand Avenue redevelopment area which governs the overall stormwater management of the Val-Gate district has been 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 must be consistent with the Grand Avenue redevelopment master stormwater management plan prepared by the city and 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 1st Street Redevelopment PUD shall be required to participate in the Grand Avenue redevelopment stormwater management facilities and shall enter into an agreement with the city approved as part of the site plan stating that the developer will provide improvements or contribute fees per their pro rata share in accordance with the Grand Avenue East stormwater connection fee district as approved by the city council on April 21, 2014.
As part of the Grand Avenue redevelopment stormwater project, it is anticipated that a stormwater structure will be installed across a portion of the developer's property. The developer agrees to provide to the city an easement for said structure. The city will endeavor to structure the construction of the stormwater improvements in such a manner as to minimize the impact on the business operations of the businesses within the 1st Street Redevelopment area.
