INTRODUCTION ' The following is a storm drainage analysis for the proposed site development for The Savings Bank of Rockville,located on the south side of Ellington Road at the intersection of Clark Street ' in South Windsor, CT. The object of the Hydrologic Analysis was to size the proposed stormwater drainage system to adequately collect and convey the stormwater runoff for a storm with a return frequency equal to 10 years. The proposed stormwater drainage system for the proposed development is to outlet into the existing Swale on the property which flows into the Ellington Road drainage system and discharges on the north side of Ellington Road. ' The axiom of design used in the hydrologic study was; Hydographs Hydroflow software program for the analysis of the existing swale and outlet, SCS method for determining the sizing ' of the retention basins /biofilters and the rational method for culvert sizing. The following pages contain the charts, graphs, maps and calculations involved in the stormwater drainage system design. The determination of the peak rates of stormwater runoff adhere to the methods ' suggested in the Connecticut Soil Erosion and Sediment Control Guidelines. DRAINAGE SYSTEM ' The approach to the stormwater management analysis for the site included a comprehensive review of the drainage patterns for both on-site and off-site contributory areas. Utilization of the USGS Quadrangle Map, USDA Soil Survey Map, Town of South Windsor Topographic Maps, abutting property recent development and field investigation was required in order to establish the characteristics for all tributary areas. ' The primary goal of the drainage system design is to offset any negative imp acts related to runoff and comply with Town, State and Federal requirements. ' The proposed storm water managements stem consists of directing proposed parking lot runoff Y gp p p g and proposed building roofs into a retention basin/biofilter stormwater filtering system. The ' 2 systems were sized to contain the first inch of rainfall from the proposed development. Storm water runoff from larger storm events will pass through the filters as recommended for best ' stormwater management practices. The downstream control on the swale is a 12"rcp pipe. The pipe then enters the Ellington Road drainage system. The site is a natural detention area for the Deming Street drainage system,the detention basin outlet for the newly constructed Post Office ' and the abutter on the east. By not restricting our larger design storms we pass through the 12" pipe before the other storms reach the oulet, thus avoiding coincidental peaking of the design storms. This is demonstrated in the following calculations. The upstream stormwater from the ' east abutter has been previously treated with an upstream on-site biofilter and will be conveyed to the existing stream through a culvert. ' SUMMARY The stormwater management system has been designed in accordance with current and accepted ' engineering practices and methods. 87546W l0UAL0211 A.W PD Corres. Fuss&O'Neill Inc.

The approved site plan for the adjacent property (Tolland Bank Site) N/F Richard S. Kelly has a level spreader exiting the property at the southwest corner. This will cause a problem for the proposed 5' concrete walk and rear parking area. Applicant should coordinate grading in this area to eliminate any possible problem. 2. The proposed 6"water service crossing over the proposed sanitary sewer lateral seems to be in conflict. A detail should be provided showing proposed elevations of pipes. Sheet 9 1. Detail of storm drain trench is not the Town standard. When pipe other than RCP is used, stone is to be used as bedding and is to be placed at least up to the center of the pipe (see attached).

PETER JAY ALTER TELEPHONE (860) 652-4020 � (860) 652-4022' April 15, 1999 Marcia Banach, Director Office of Community Development Town of South Windsor 1540 Sullivan Avenue South Windsor, CT 06074 Re: Savings Bank of Rockville -Administrative Offices, Ellington Road Dear Marcia: As you may be aware I represent The Savings Bank of Rockville with respect to its pending development application for the property it owns on Ellington Road and Clark Street in South Windsor. As part of the application process,preliminary plans have been submitted to Town Staff for review and comment. One of the comments that was received from staff was a request that The Savings Bank of Rockville consider installing a walking path which would permit pedestrians to traverse from areas easterly of The Savings Bank of Rockville site, in particular,the assisted living facility, to access the post office facility recently completed on Clark Street. The Savings Bank of Rockville has examined this request with the assistance of its engineers, Fuss and O'Neill, Inc., and its architectural consultants,Bay State Design Associates, Inc. The proposed walkway presents several difficult issues which I would like to bring to your attention for the purposes of discussion and resolution: 1) After reviewing ADA Handbook information and ADA minimum requirements, it is my opinion that this public access walkway must be ADA compliant in its design and construction. These requirements will impose substantial additional cost and will result in substantial and additional disturbance of wetlands for the construction of the pathway. 2) An examination of the Post Office site plan indicates that a substantial portion of this site is fenced off for security purposes by the Post Office. An additional area has been regraded for detention of storm water purposes and has resulted in steep banks rising up from The Savings Bank of Rockville property onto the Post Office property. The contour differences and fence and building configuration of the Post Office site make it extremely difficult to find a viable ' ALTER AND SHERWOOD, Lr.c Marcia Banach, Director April 15, 1999 Page Two access point from The Savings Bank of Rockville property to the Post Office property. 3) I have indicated to the Bank my concern regarding the long-term liability created by a private walkway to provide public access from other properties through The Savings Bank of Rockville property. Has the Town entered into discussions with the assisted living complex and the Post Office complex to assure that all segments of the pathway will be constructed in a similar manner and will be maintained to a similar condition for the long term. As often happens, a sensible concept proves difficult to actually execute. Absent a resolution of the issues raised above, it is my recommendation to The Savings Bank of Rockville that other options for access be explored. In the alternative,if the Town of South Windsor has an interest in completing this walkway system as a public improvement, my client is ready, willing and able to grant a Permanent Easement for public access in favor of the Town of South Windsor in order that the Town may construct and maintain a walking pathway through The Savings Bank of Rockville property. As always, I am happy to discuss this matter with you at greater length,but I wanted to alert you to my client's concerns as soon as possible. Please feel free to contact with any questions or comments. Thank you. Very truly yours, ALTER AND SHERWOOD, LLC NJa, r cc: ayles - Fuss and O'Neill, Inc.

I am concerned that the Inland Wetlands Agency's approval may require changes to the plan which would then have to be presented to the Planning and Zoning Commission. Under the circumstances of this application it would make sense to wait until we have completed our application before the Inland Wetlands Agency. In addition, this letter shall serve as a request for an extension of the statutory period for action on the application to the extent required by law.

All erosion and sedimentation control measures are to be in place prior to earth movig�perations in each area and maintained/cleaned out during construction.
