Present: Chairman Wellington, Clerk Latham, Planners: Chavaree and Mendes Town Planner Maurer. I. The Board reviewed the Memorandum of January 26, 1972 of William May, P.E. concerning the drainage plan for the Cabot, Cabot and Forbes Industrial Park, and a memorandum from Town Planner Maurer, concerning a suggested recommendation for the Planning Board to consider presenting to the Board of Selectmen. The Board noted that the following alternatives should be considered. 1. Construct an additional box culvert at School Street having an interior dimension of 6 feet. Estimated cost $12,500 If this work were completed, there would still be a flooding problem at School Street during the 50 -year storm because the culverts under the railroad would not have the capacity to pass the volume of water that flows under School Street. Therefore, the area between School Street and the railroad would flood. 2. Install two additional 6 foot culverts under the railroad. Current rail- road regulations would require that these culverts be placed into a sleeve that is jacked under the railroad bed. The cost is estimated at $900 per foot/pipe. The estimated distance that the sleeves would have to be jacked is 70 feet for each pipe. Estimated Cost $84,000 3a. When the culverts have been jacked under the railroad, then the water would be passed down to Oak Street. In order to prevent any flooding over Oak Street then two additional 5 foot by 10 foot box culverts would have to be installed. The increased flow of water would then be passed on into Norton. Estimated cost $20,000 3b. If there is an increase in the culvert capacity at School Street and the railroad but not at Oak Street, then Oak Street will flood. The alternative is to raise Oak Street and retain water in the area between the railroad and Oak Street. This alternative could conceivably place a considerable amount of developable acreage under water during a 50 -year storm. Estimated cost $11,000 4. Retain water within the industrial park and/or in conjunction with construction of Route 25 to the extent necessary to limit the peak discharge such that the area south of School Street would not experience a flood worse than the one in the Spring of 1968. ! The Board agreed that the following recommendations be forwarded to the Board of Selectmen: 1. Approve the internal drainage plan of the industrial park subject to any modifications which may be required under the Mansfield Subdivision Rules and Regulations. 2. Said approval to be limited to the drainage system shown on the map entitled 1-95 Industrial Center at 495, Mansfield, Mass., Basic Drainage System Layout'' prepared by H. W. Moore Associates, September 10, 1971, more specifically, the drainage system on the easterly side of proposed Route 25 namely points 15 and 40. The drainage system west of these points would become part of the coordinated drainage design between the Massachusetts Department of Public Works, Cabot, Cabot and Forbes and the Town of Mansfield. The design for the relocation of Hodges Brook - Project number M®245, would not be effected by this recommendation. However, that project should still be subject to review and modifications as may be required under the coordinated design of the total drainage system. 3. That the following design criteria would be used by these three agencies in developing the final design for the drainage system. That the drainage system be so designed as to limit the downstream discharge to School Street, during a 50 -year flood design so that peak run-off conditions will not substantially exceed those that existed prior to the construction of Route 25 and the Industrial Center. 4. That a letter of agreement be obtained from Cabot, Cabot and Forbes stating that they would agree to work with the Department of Public Works and the Town of Mansfield in working out a solution to this problem, and that they would agree to conform to an equitable solution. A similar letter of agreement should be obtained from the Massachusetts Department of Public Works. Town Planner Maurer will draft letter to the Board of Selectmen concerning the alternatives and recommendations. 2.
