ARDEN HILLS PLANNING COMMISSION—April 6, 2011 11 3.B. Planning Case 11-006; Preliminary Plat and Comprehensive Plan Amendment; . PulteGroup and Alliant Engineering; 4500 Snelling Avenue North — Public Hearing (continued) Chair Larson clarified the continuation of Keithson Drive would be 30-35 feet from the corner of the house located at 4503 Keithson Drive. Mr. Wicklund stated this is correct. Currently the north curb edge is 20 feet from the right-of-way and this will be adjusted to 25 feet. From the north edge of right-of-way to the house is an additional 10 feet. Chair Larson asked if the roads close proximity to Mr. Bartlett's property would cause any problems. Mr. Wicklund stated there are no anticipated problems with this section of road. He stated the GeoTech Report for the soils on this site show suitable material to work with and they will be able to get this material to a tolerance that can support a road. He clarified that soil borings have been taken throughout the site and they have not found any problems with peat that were reported by residents. Ron Intertech did six geotechnical borings and a contracting did twelve test kits and all the material appears to be suitable for construction. Commissioner Hames stated the residents had stated their homes had been built on wetlands and she asked to clarify that the proposed development would not be building on the wetlands and the wetlands are delineated separate from the home sites. Mr. Wicklund stated this was correct. No portion of this project would be built in wetlands. Commissioner Thompson asked about the wetlands on Lot 18, Block 4 and the concerns expressed by the residents. Mr. Wicklund stated the rear yard would be kept for the area behind it to drain through this lot. He clarified that both Rice Creek Watershed District and the City have requirements in their subdivision ordinances and design standards for poor elevations related to drainage ways and minimal slopes in rear yards. Pulte also has established criteria for these areas. The front portion of the lot will be built up and the slope to the rear of the property will be more gradual. The City could set up a drainage easement for this area so that in future years the landscaping is not changed to affect the drainage. He also stated there would be a retaining wall built on the east side of this lot, outside of the wetlands,to address the erosion problems that have occurred on this property. Public Works Director Terry Maurer stated the City would be requesting a drainage easement be put in the proper location to accommodate the grading and allow for the correct drainage in this area. He stated he would recommend the City request a letter of credit to ensure all the improvements are done, reviewed and accepted by the City. The City will have an inspector on the site to ensure the project is being completed according the plans and specifications submitted to the City.
