Sharmeen AI-Jaff and Alyson Fauske presented the staff report on this item. Planning Commission Summary - May 15,2007 Commissioner Keefe asked staff to explain the planning process involved with this parcel because of his concern with the mass grading and tree loss on the property. He also asked for clarification on the road right-of-way variance. Commissioner Dillon asked for clarification of the proposed use for the outlot, the narrowness of the lots and their ability to accommodate homes without future variances and an explanation of the ownership of the different lots. Commissioner Papke asked about traffic flow in the area. Paul Otto with Otto Associates spoke on behalf of the applicants and clarified their plans for custom grading of the site. Bob Amick, one of the applicants, addressed the issue of builders and selling price of the homes. Chairman McDonald opened the public hearing. Greg Fletcher representing the Lotus Lake Clean Water Organization stated their support of the variance to allow a smaller roadway width, but had concerns with the runoff from the additional impervious surface into the wetland pond in the southeast corner and asked that the city hold off on additional development until that pond is able to handle additional runoff. They also requested that rain gardens and permeable driveways be incorporated into the design of the development. Michael Kohane, 6870 Yuma Drive noted that service vehicles needed to be included in the traffic study and stated a concern with young children moving into the area, runoff into Lotus Lake, setbacks, preservation of the trees in the outlot, and clarification on the 50 foot road variance. Matt Keffin, 516 Big Woods Boulevard asked for further detail of the floorplans and home types that will be built in this development and the location of proposed driveways in relation to the retaining wall for the Big Woods Addition. Deb Lloyd, 7302 Laredo Drive suggested showing the 60 by 60 house pad to ensure setbacks are being met. Roberta Schlueter, 580 Fox Hill Drive asked the developers to be considerate and respectful of the existing residents and take into consideration automobile lights shining into their house, construction traffic on Fox Hill Drive, tree loss, and clarification on street lights, whether or not they're going to be installed. Randy Schlueter, 580 Fox Hill Drive reiterated that the main issue is the amount of traffic being brought into the area and headlights shining into their home. Mark Nelson, 6890 Navajo Drive, having lived in the area for 20 years, feels the lot sizes in Chanhassen are too small for the homes being built today, and expressed concern with the impact on Carver Beach Road from construction traffic. Jeff Kleiner, who has lived at 655 Carver Beach Road for 28 1/2 years, expressed concern with the clear cutting of trees and the sewage capacity of the lift station. Craig Benz, 620 Fox Hill Drive, a new resident, had concerns with increased traffic and asked that residents of Fox Hill be included in the architectural review of the homes going in. Paul Huber, 6663 Horseshoe Curve asked for clarification on lake and dock rights for this development. Chairman McDonald closed the public hearing.
