developments. The Minnesota Pollution Control Agency controlled the discharge rates. The developer was going to try to keep the water on site, or to use filtration. O'Connell made a motion to pass on the denial and the staff and Board recommendations: • Contact the St. Paul Regional Water Utility and Vadnais Lake Watershed District. • Buffering for Pipeline easement in the northeast comer lots. • Street lighting should be downward focused, no spillage. • As long as the developer was requesting a re- zoning would he consider a PDO to preserve an additional 17 acre additional open space. • Signage should be placed on buffer boundaries to indicate buffers exist, and covenants should be established with the homeowners' association prohibiting encroachment. Halen seconded the motion. Motion carried unanimously. The Planning and Zoning Board tabled the Preliminary Plat Hearing because of platting issues. The Preliminary Plat is before you again. Not too much has changed. The Rice Creek Watershed however has made a recommendation (not a requirement) that the street width be reduced to 29 feet instead of 32 feet. Please find the most recent Plat Proposal (Attachment 1). Analysis: Reducing the street width from 32 feet to 29 feet would reduce the amount of impervious area in the development by about 23,000 square feet. I agree with the recommendation. However, there are no adopted standards under the subdivision code providing for this, and there was concern from public services regarding street plowing and fire and pedestrian safety. Chief Bennet indicates the Fire Department needs 20 feet for access. A 20 -foot road would restrict parking to one side of the road in order to achieve this 20 -foot fire access. Please refer to attached street design section from the Center for Watershed Protection for more information on road design case studies (Attachment 2). I stated at the previous Environmental Board review of Stoneybrook Preliminary Plat that Stoneybrook is a very wet site. There is little room for infiltration, but plenty of room for improved design in filtration. Residents living in this development are going to experience "soft- and - mushy" situations. I think the developer should go beyond standard disclosures and inform residents before they sign purchase agreements on this situation. An informational brochure describing the buffering, and soft and conditions that may be experienced should be given to them.
