While others in the immediate area are concerned about wetland delineation, conflicting reports, etc. My concern lies solely in the management of water run-off from the project.

The small storm sewer that was constructed has alleviated the threat to my home stmeture, but because the asphalt at the intersection was not properly installed, a fair amount of water from Tonka View Ln still crosses Wildhurst 'frail, enters the drainage ditch and is conveyed to my level, lakeside lawn. A heavy rainfall results in standing water, draining slowly with time, into Forest Lake Bay. Concerns were expressed by members of the Watershed District that although the Brenshell drainage plan meets their requirements, there is a potential for disaster inherent in the design. The burms for two holding pond.s will be constructed from natural, resident soils and a four-inch weir will control the rale of drainage from the pond. If the four-inch weir plugs with leaves or debris, the pond will over flow to a 12-inch pipe. If the pipe -'T'.'r.k 1 -1 -B1 .‘J -«*i rr i l-•m .MiT.>.r
