Request for CouiK:il Action continued page 6 of 10 March 11, 1994 Zoning FUe #1901 The DNR is concerned with the drainage coming from the northeast along Willow Drive and to an existing pond area adjacent to Luce Line. Drainage from the northeast will not drain to the pond but will drain through a culvert at extreme east. Developer shall increase storage capacity of detention ponds at the northeast coircr of the Dickey property to minimize any impact on existing developed properties in Countryside neighborhood. Review Exhibit R, the DNR asks that a new culvert be installed under the horse trail in the area by the pond at the east end of the property. Review Exhibit N. the property is located within three major watersheds - Lake Classen, Maxwell Bay and French Creek. The majority of drainage from the propeny flows to French Creek. The majority of site drainage is routed through established drainage ways onto adjacent property. All land alteration will necessiute the installation of erosion control aral shall remain installed and in place until ground cover is restored. The City code requires a 26’ setback for all land alterations from a designated wetlands. There is an encroachment of the 26’ setback zone from the designated wetland within Lot 1, Block 1 at the southeast comer of the Coffin property where grading alterations are proposed at the edge of the wetland. Engineer notes that this would be a logical location for the pond which will function to protect the wetlaiKl from sediment deposition and would appear to satisfy some of the necessary findings for granting variances to encroachment of a wetland as follows: 1. 2. Proposal appears to be consistent with the objectives encouraging land uses compatible with the preservation of natural land forms, vegetation and the marshes and wetlands. The proposal does include development of land and water areas essential to continue the temporary withholding of rapid runoff of surface water which would create downstream flooding or pollution. The issue for staff has been to provide adequate notice to a land owner who purchases a lot with undesignated wetland types as they will not be shown as drainage easements on the plat surveys. We have recommended that a special covenant be created for the filing against the chain ot title of each of these properties that will include mapping metes and bounds descriptions of the location of the various type wetlands with a disclaimer that before any land alterations or structures are proposed within these protected areas that the property owner first obtain necessary approvals from the Corps and the MCWD.
