The handicapped ramp will provide access from the end of Boylan Avenue to the existing park trail. The plan is to cross the swale with a small bridge with associated head walls or to use the equivalent of two 36" pipes depending upon the Parks and Recreation Department design committee decision related to cost and appearances. The grass swale leads down from Clay Street on the south side of the park and runs parallel to the southern boundary of the park and carries storm water flow from the storm sewer system on St. Mary's Street. The crossing will be in the grass area east of the existing rip rap apron from an adjacent property. The project will entail some grading to obtain the proper slopes required for the handicapped trail access and will be 5'-0" wide and paved in concrete. We are requesting the project review remain open until we can obtain bids on the project to determine the affordability of a bridge with headwalls verses a culvert crossing. 1'he decision will also be dependant upon approval and or recommendations by your agency. If there are any questions please contact John M. Iloppe at 890-3287 the project manager and designer. Sincer y, Jo M.

Stormwater (required by DWQ) Describe impervious acreage (existing and proposed) versus total acreage on the site. Discuss Stormwater controls proposed in order to protect surface waters and wetlands downstream from the property. If percent impervious surface exceeds 20%, please provide calculations demonstrating total proposed impervious level. Impervious surfaces 1.74 acres- total site 20.83 acres = 8% new work is 1612.7 sq. ft. Or .03 acres. 1.77 total impervious acres including new work 8.4% of total site. XII.
