Town Engineer Town of South Windsor 1540 Sullivan Avenue South Windsor,CT 06074 Re: Site Plan Application for Twin Manufacturing 273 Chapel Road South Windsor,Connecticut A 48'x 30' building for storage of a new helicopter and a helipad designed to meet F.A.A. standards is being proposed on the property of Twin Manufacturing located at 273 Chapel Road.Much of the remaining wooded property to the rear of the existing building and pavement will be cleared as part of the improvements.We used TR 55 to analyze both the existing and developed runoff conditions for the site and the results indicate no measurable increase in peak runoff for any design storm 2-100 yr.,except for the 25 yr. storm.Due to the location of the site in the lower reaches of the Podunk River watershed, and the minimal increase in peak runoff from the site,detention on the site is not warranted.The proposed improvements are designed for minimal exposure to traffic associated with the use of the helicopter and the vehicle(s)used in transporting the helicopter between the helipad and the garage.It is anticipated that runoff from this light traffic area will receive the appropriate water quality renovation through contact with the vegetation.No additional measures have been proposed for stormwater management.I have included the TR-55 analysis and a copy of the drainage area map used for your review. Please let me know if you require any additional information. Sincerely, Design Profes 'onals c. K n M. Is od,P.E.
