ELK RIVER W AL-MART STORE #3209-01 PROJECT NARRATIVE September, 2004 The project site, located at 18185 Zane Street in Elk River, Minnesota, was previously approved as part of a Planned Unit Development (C-3 Highway Commercial district) for a Wal-Mart Retail Store with future expansion (65,000 SF) on December 21, 1999. A Conditional Use Permit (CUP) was approved by City Council on October 18,1999. The total Wal-Mart parcel comprises 28.3 acres; however, approximately 8.3 acres will be disturbed for grading, paving, landscaping and utility infrastructure improvements. Zoninl! As stated above, the original store was approved as part of a PUD. Provisions of the CUP require Wal-Mart to revise the CUP when any proposed expansion to the store and parking take place. The expansion proposes to comply with the original PUD with one slight variation from the original site plan. This variation includes new building entrances, in addition to the expansion to the end of the building. Two new store entrances will be built, requiring realignment of the drive immediately in front of the store. The new design will minimize the curves that vehicles now deal with while driving along the front of the store. Site / Buildinl! The original store was originally constructed for 140,991 SF of retail building area with 757 parking stalls (5.3 ratio). The expansion proposes 69,671 SF for a total building area of210,662 SF. Excluding warehouse space there is 180,334 SF of net sales area, which requires 902 parking spaces (1/200). The 30,328 SF of warehouse space requires 16 parking spaces (1/2,000). Total parking spaces required is 918; therefore, we do exceed the parking spaces required by Code. The expansion will provide a total of975 parking stalls. The proposed building heights will be less than 35' above their average grade lines. Parking lot light standards are anticipated to be approximately 42' in height, similar to the existing height. The architectural scheme for the expansion will be consistent with the original design to maintain and enhance the neighboring property; i.e., painted block exterior, contrasting colors including earthwork tones with a green accent color, varying roofline, accent materials at the two vestibule entrances, additional pilasters similar to existing, and an upgrade to the garden center entrance. In addition, screening will be provided for trash compactors, truck wells, compressors, storage areas, rooftop equipment, etc. as required in the code. Storm Analvsis The original storm design analysis included the store expansion area, which was designed for the 10- and 100-year storm events. The storm runoff was designed to drain to two sedimentation basins, and then to wetland areas located north and south of the building.
