Memo To Planning Commission/P 97-20 January 27, 1998 Page 3 Road Extension • As previously mentioned, the proposed road is planned to continue south through the adjacent property and connecting to 171st Avenue. The exact location where the proposed road should meet the adjacent property is an issue which will need to be discussed further between the two property owners. The property owner immediately to the south has indicated a need to lower the grade of the roadway approximately four feet. This will allow the street to match their property at an acceptable grade. Given the topographic conditions of the property the road location as it matches the adjacent property will be more critical than if the property had no grade and the adjacent property could easily match into the road. Right of Way/Easements The road right of way at the project's entrance should be adjusted to provide a taper rather than 90 degree corners. This will ensure enough boulevard area remains after the street is constructed. The plat indicates 6 foot side yard and 12 foot front and rear easements. These can be reduced to 5 feet and 10 feet, respectively. • An easement should be established on Outlot C along the County Ditch. The easement dimension should be 50 feet from center of the ditch. Trees The property has large masses of existing trees spread out throughout the plat. The primary mass of trees occurs along the ridge line and consists of a mixture of hardwoods extending down to the edge of the wetland. There are also some existing trees along County Road No. 33 which should be able to be preserved with the exception of the street construction and connection to County Road No. 33. Given the steep grades along the ridge line where a majority of the development is to occur, the use of retaining walls should be considered to minimize the amount of grading while at the same time preserving as many trees as possible. Wetlands The City has begun the review process for the proposed wetland fill and mitigation. Approximately 6,900 sq. ft. of wetland will need to be filled to accomplish the road crossing. There will also be a mitigation plan which will need to be approved and completed by the developers in exchange for filling the 6,900 sq. ft. of wetland area. 0 \\elkriver\sys\shrdoc\planning\pc\p97-20.doc
