Prior Lake, MN 55372-1714 MINUTES OF THE LAKE ADVISORY COMMITTEE September 20, 2005 I. CALL TO ORDER The Lake Advisory Committee (LAC) Meeting was called to order at 6:00 P.M. Members present: Harry Alcorn, Marv Mirsch, Donna Mankowski, and Dan O'Keefe. Members absent: Brad Beneke Others present: Larry Poppler; Assistant City Engineer II. CONSIDER APPROVAL MEETING MINUTES III. NEW BUSINESS ,.-- ~ A. Develooment Standards Poppler provided a presentation on development standards. The presentation was broken down into four speaking points: 1. City of Prior Lake Development Standards 2. Administering Standards on a Sample Project 3. Watershed District Standards 4. Upcoming New Developments B. Citv of Prior Lake Standards Pop pier began the discussion of the development standards for the City of Prior Lake. Poppler outlined many of the different standards in the City of Prior Lake's Public Works Design Manual. The discussion concentrated on the storm water and erosion control standards. Alcorn asked what is the biggest issue facing the City in terms of storm water or erosion control. Poppler responded that the builders have been the biggest issue in terms of erosion control. The builders, the builder's subcontractors, or builder's delivery workers drive over the silt fence and track mud and dirt into the street. Many of the site erosion control features are missing or poorly placed. The Engineering Department is working with the Building Department to facilitate a solution to deal with sites not meeting erosion control standards. It is a hard issue to tackle www.cityofJriorlake.com Phone 952,447,4230 / Fax 952.447.4245 r- because there are so many builders and so many people come and go from each house or building during construction. Alcorn suggested increasing the permit fees and hire a person who can monitor the builders. O'Keefe stated that not every community has the water features that the City of Prior Lake has. If a builder wants to do work in the City of Prior Lake they should have to comply with the erosion control features so that we can protect our water assets. Mankowski added that the builders and developers need to be accountable for the erosion control on their projects. C. Administerina Standards on a Samole Proiect Poppler showed how storm water and erosion control features is incorporated into a particular site. D. Watershed District Standards ~ Poppler stated that many of Watershed District's storm sewer and erosion control standards are the same as the City's. The Watershed District has an infiltration standard, which the City of Prior Lake does not currently have. Currently a project must receive approval from the Watershed District and the City of Prior Lake. The Watershed District and the City of Prior Lake have been discussing the possibility of having their standards be the same and having the City perform the permitting and approval for development projects. Poppler also discussed the Watershed District's sediment trap manhole. Mankowski stated that it is good that the Watershed District and the City of Prior Lake are working together to have the same standards. E. Uocomina New Develooments Poppler presented a map showing the new developments, which are currently being designed or built. The map is attached with the meeting minutes. Some of the projects, which were discussed, were Stemmer Ridge, Jeffers Pond, Maple Glen, and Enclave at Cleary Lake. IV. OLD BUSINESS A. Web Camera Uodate .- Alcorn has spoken to Nathan Oster regarding the web camera. The yacht club does not have cable on the island so a wireless connection would need to be established. The wireless connection is $5,000.00 so it doesn't seem feasible to place the web camera on the Yacht Club Island. A rotational web camera is $7,000.00. O'Keefe asked how the camera would be used. 2 ,.-.. Alcorn answered that the pictures from the camera would be shown on a website. Prior Lake residents or users of the lake could see how much lake traffic or what type of weather is out on the lake at a particular time. It is also a way to promote the lake and the City of Prior Lake. Funding would occur from the private sector and the City would provide donors with web space on the website. The location of the camera is the key component as the location determines the cost. At this point the location choices include the Yacht Club and Captain Jack's. V. ANNOUNCEMENTS A. City Hall Uodate The City Hall project was awarded to Shaw Lundquist. They will begin construction in the next few weeks. B. Water Resource Enqineer The City has hired Ross Bintner as the new Water Resource Engineer. His start date is November 1 st. C. Reaooointments ~ Reappointments for the LAC are up for three members.
