City Of Pequot Planning Zoning From: Tim Houle[thoule @wsn-mn.com] Sent: Wednesday, August 24, 2005 3:12 PM To: Chuck Marohn (E-mail) Cc: Dawn Bittner(E-mail); "Dave Reese"@smtp2.onvoy.com; "Jeff Miller"@smtp2.onvoy.com; "Mike Rude"@smtp2.onvoy.com Subject: Pequot Lakes-Wilderness Point Resort Utility Plans Chuck, Dave Reese, P.E., from our office gave me a 8/19/2005 memo, which you were copied on, for the above subject project. As you know, I was not in attendance at the August 18, 2005 Planning and Zoning Commission meeting, so I discussed the memo and the issues with Dave for awhile. I then reviewed the following: 1. Streets The roadway to and along a portion of the plat is City R/W. However, the roads within the plat are not on City R/W and therefore will be the Association's responsibility. 2. Storm Drainage Similar to the roadways, the storm drainage will be on Association "property" and not on City R/W, and thus will be the Association's responsibility. It appears from the preliminary grading plan that storm drainage/infiltration/sedimentation control is being addressed and space/grading is being set aside for this. However, I did not do any calculations nor did I review any calculations for storm drainage to "check" them. However, they will have to apply for an NPDES General Stormwater Permit that will address temporary and permanent erosion and sediment control requirements (another "check" point) . 3. Sanitary Treatment Dave has identified primary and secondary drainfield sites for the various anticipated building phases. While those that have to maintain it may disagree, my personal opinion is that it is not objectionable to spread out the drainfields as each Phase comes "on line" as opposed to having one larger drainfield for all Phases. I reviewed the design for Phase 1 that Dave included in his memo. The flow determination, while in my opinion is on the high side, meets the various regulations. >From a field evaluation by our Environmental Department, the Soil >Sizing --� Factor is conservative (i.e. it could be dropped for future drainfield designs) . The calculations appear to be appropriate for Phase 1. As Dave stated in his memo, they will also be submitting an application for the required MPCA NPDES permit (another "check" point) . 1
