Masxun Furniture/CU 04-39 January 18, 2005 Page 2 . . There is also an existing drainage and utility easement dedicated as part of the original Elk River Crossing plat which is not reflected on the site plan. A portion of this drainage and utility easement will need to be vacated so that the parking lot and building can be constructed within this area. . The site plan shows customer traffic entering from 179th Avenue in Elk River Crossing and delivery and service vehicles entering from Industrial Circle at the south of the building in Elk River Business Park. B. Grading, Drainage, and Erosion Control Plan . As mentioned in my memo regarding the plat of Elk River Crossing 6th Addition, the drainage for this area is divided into two parts, based on the original plats of Elk River Crossing and Elk River Business Park. The northern portion of this site and most of Lot 1 are sized into the original drainage plan for Elk River Crossing. The southern portions of the two lots are sized into the drainage system for Elk River Business Park. We are currently reviewing the drainage calculations submitted to ensure that they not only accurately reflect the drainage from the Maxsun Furniture site, but make provisions for Lot 1, Block 1 of Elk River Crossing 6th Addition, taking into account the two different drainage systems. . . The development of the Maxsun Furniture site requires the reconfiguration of the original ponding area constructed with Elk River Crossing Addition. The reconfiguration falls into an existing H.u.C. easement of record adjacent to the east plat line approximately centrally located in Lot 2, Block 1. We believe this easement belongs to Great River Energy. Before this pond reconfiguration can be approved, it will be necessary for the developers to either get this easement vacated or get written permission from the owners of the easement to allow a ponding area within the entire area of the easement. . Due to the size of the area disturbed for the Maxsun Furniture site, an NPDES permit will be required prior to any work on the site. As part of the requirements of the NPD ES permit, the development will be required to submit a Storm Water Pollution Prevention Plan (SWPPP). As you are aware, the City has prepared a generic SWPPP to be used on project such as this, so it will simply be a matter of filling in the blanks and signing the City's generic SWPPP. One thing that should be noted is the current grading plan does not reflect silt fence around the entire site. According to City policy, the entire construction site will need to be encompassed with silt fence prior to any construction activities. . The construction entrance for all activities is shown off 179th Avenue. This should be changed to Industrial Circle. It would be better for construction activities to enter the site from the south where there is less vehicle activity, rather than from the north side, conflicting with all the commercial traffic in this area. .
