Green Company <br /> y <br /> August 20, 2002 <br /> File: 818840J-0240 <br /> Ms. Michele McPherson <br /> Director of Planning <br /> City of Elk River <br /> 13065 Orono Parkway <br /> Elk River, MN 55330 <br /> RE: PINES TOWN OFFICE PARK <br /> Dear Ms. McPherson: <br /> As requested, we have reviewed the submittal package for the Pines Town Office Park. This is the <br /> business condominium proposal on Lot 2, Block 1 and Lot 1, Block 2, Mulvaney Point. The submittal <br /> package was prepared by Mohagen Architects, Ltd., and Ulteig Engineers, Inc. Based upon our <br /> review and comments received at the staff review meeting, we would offer the following comments: <br /> • 1. The paved area and green space behind Buildings 1 and 2 drain directly to Tyler Street. <br /> There is no internal storm sewer that intercepts the runoff from this area. The storm sewer <br /> system should be modified to pick up the runoff from this area and route it through the <br /> proposed development pond. <br /> 2. The area behind Buildings 6 and 7 appears to have omitted the 908 contour. This area, <br /> which is essentially landscaped, drains off of the site onto Lot 3, Block 1. The only concern <br /> in this area is where the roof drainage goes. If roof drainage off the back of the buildings <br /> also flows this way, it should be intercepted in the storm sewer system or by gutters placed <br /> on the rear of the buildings to direct roof drainage internally to be picked up by the storm <br /> sewer system. <br /> 3. There were no storm drainage calculations provided with this submittal package. Storm <br /> drainage calculations including pond design will need to be submitted, reviewed and <br /> approved prior to final approval of the proposal. <br /> The proposed storm sewer concept for these two lots is to have an internal storm sewer <br /> system interconnected under Third Street with a pond constructed just southwest of Lot 1, <br /> Block 2. The storm sewer systems for Lot 2, Block 1 and Lot 1, Block 2 operate as one <br /> system. We question whether or not the storm sewer systems should be designed <br /> independently, each outletting separately to the proposed pond. If either of the <br /> condominium areas is ever intended to be sold separately, independent designing would <br /> likely provide for an easier real estate transaction. <br /> 411 <br /> Ltr-082002-McPherson[1] <br /> 1326 Energy Park Drive • St. Paul, MN 55108 • 651/644-4389 fax 651/644-9446 toll free 888/368-4389 <br />
