i i June 21, 1995 File: 230-270-11 CONSLLTING ENGINEERS 1326 Energy Park Drive St. Paul, MN 55108 612.644.4389 1-800-888-2923 fax: b12-644.9446 Mr. Gary Schmitz Planning Assistant City of Elk River 13065 Orono Parkway P.O. Box 490 Elk River, MN 55330 RE: WEATHERWOOD SUBDIVISION REVIEW Dear Mr. Schmitz: As requested, we have reviewed the submittal for the Weatherwood proposed plat. The submittal consisted of a one sheet Grading and Drainage Plan signed by Ken Gus and James Kyro. The plan was dated May 1995. Based on input from the concept review meeting held on June 13, 1995, and the follow-up meeting with the Developers on June 16, 1995, we would offer the following comments. CIVIL ENGINEERINCr ENVIRONMENTAL 1. The entrance road at the west end off of Zebulon Street causes the existing structures +4UNICIPAL on the exception to the plat to not meet building setbacks. It is recommended that the ~NNING road alignment be pushed further to the north in order to provide adequate setback souDw,asrE .distances for these existing structures. STRUCTURAL SURVEYING 2. Since this project is a rural subdivision, each lot should be able to support two septic TRAFFIC systems. The idea behind this is if the original system fails, a new system cannot be TRANSPORTATION built in that location; therefore, in order to upgrade a failed system a new site must be provided. It is questionable whether all lots in this plat can support two on-site ELECTRICAL/MECHANICAL ENGINEERING: septic systems in addition to a house pad. Some of the questionable lots would be Flvac Lot 3 Block 3, which has a treatment pond, ditch easement, and wetland all included POWER DISTRIBUTION within its boundaries. Another questionable lot would be Lot 6 Block 3, which has SCADA a relatively steep hill which makes it difficult to build conventional on-site sewage SYSTEM CONTROLS systems. We would recommend that the Developers show on each lot the locations for the proposed on-site septic systems in addition to the building site. In many cases, there will be some flexibility where these can be relocated in the future, but on some of these severely restricted lots it is important to demonstrate the ability to make the lot buildable prior to the plat being filed. In follow-up to this, we would also recommend that the City require soil borings on some of the lots which may be questionable relative to water table for the construction of an on-site sewage system. The Building and Zoning Department ~FFicES iN: .MINNEAPOLIS should be able to identify some typical lots in which the Developers could provide soil boring information. This information would be valuable to the home builders in PRIOR LAKE the future as long as the septic system is proposed to be built in relatively the same ST. PAUL location as the soil boring.
