Town of Mashpee Conservation Commission 16 Great Neck Road North Mashpee, MA 02649 was further stated that a dry well was proposed to capture roof runoff from the new porch and that sediment controls and work limits would be maintained during construction. The property owner explained that significant termite damage and rot had been discovered between the house and the existing deck during planned repairs and replacement of exterior doors and windows. It was stated that the deteriorated deck had already been removed in order to access and repair the damaged portions of the structure. The owner further stated that no excavation or disturbance of surface soils had occurred during removal of the deck and that most remaining work would occur within the existing structure footprint. Additional explanation was provided regarding enclosure of the breezeway and modifications intended to improve the layout and appearance of the dwelling. Discussion focused on the proposed concrete walkway and restoration areas adjacent to the coastal bank. Commissioners questioned whether permeable materials and native vegetation should be used instead of concrete and lawn areas within the coastal bank buffer. The applicant and property owner indicated willingness to revise the proposal to utilize permeable materials and install native vegetation plantings in place of lawn restoration areas. Additional discussion addressed the extent of proposed disturbance within the coastal bank buffer area, flood zone delineations shown on the plans,the location of the coastal bank relative to the proposed work, and the proposed dry well system. Questions were raised regarding the amount of disturbance shown within the work limits and inconsistencies in the flood zone elevations identified on the plans. Clarification was also provided regarding the anticipated overflow route from the proposed dry well system,with explanation that overflow runoff would drain away from the waterbody based on existing site contours. Further discussion addressed restoration of the area where the deck had been removed. Commissioners expressed preference for native plantings rather than lawn in order to reduce fertilizer use and provide improved buffering to the coastal bank resource area. The applicant and property owner agreed to revise the proposal accordingly. Conservation staff stated that the overall project represented a benefit to the resource areas because the deck closest to the coastal bank would be permanently removed and replaced with native vegetation and stormwater improvements. It was further stated that installation of native plantings,permeable materials, and a new dry well system would improve site conditions relative to the existing development.

(Representative: Webby Engineering Associates, Inc.) 43- 3421 Joe Webby of Webby Engineering stated that the project involved replacement of existing deck areas with proposed additions and landings while maintaining no net increase in structural coverage on the lot. It was further stated that although there would be no increase in overall structural footprint, the project would increase impervious surfaces, which the applicant proposed to mitigate through installation of two dry wells. Mr. Webby stated that stormwater calculations had been submitted, seasonal high groundwater was estimated at elevation two, and the proposed additions would be elevated on piers in accordance with FEMA flood zone requirements. Discussion focused extensively on the location of the existing septic tank in relation to the proposed additions and structural supports. Questions were raised regarding how the additions would be supported over or near 15
