Designs that Minimized Loss of Parking Were Presented
![Page 14: Maplewood Mall Stormwater Retrofit...Concerns from the Mall’s Perspective •Appearance of features •Maintenance •Disruption of shopping, especially during the holiday shopping](https://reader033.fdocuments.in/reader033/viewer/2022060410/5f104f357e708231d44878e1/html5/thumbnails/14.jpg)
However, in some areas, mall owners were willing to lose spaces to gain aesthetic appeal and traffic control

Concerns from the Watershed District’s perspective
• Cost-effectiveness and visibility
• Strong interest in keeping some features “above ground” where they are visible and less expensive to construct and maintain
• Access to the corporate office where the company’s decisions are made
• Many utilities (some not well marked) to deal with in design and construction
• Compacted soils- low infiltration rates
