HomeMy WebLinkAboutDPW Comments1/13/26 Good afternoon Jim & Anna, We’ve completed our review of the updated ZBA application for the 40B development at 195 Phinney’s Lane, Centerville, please see below for our comments. A Road Opening Permit is required to complete work within the public right of way. Any road closures proposed to facilitate work require the submission of a traffic management plan to DPW for review and approval prior to start of construction. Note: Phinney’s Lane is under roadway moratorium through summer of 2029, coordination with DPW will be required through the road opening permit process to address post-construction restoration. The project will require a sewer connection permit be obtained from DPW prior to the start of construction. Note: Additional coordination will be required with TOB DPW and Planning and Development regarding the permitting, operations/maintenance, and ownership of the proposed sewage collection system. As part of flling for a sewer modiflcation permit, a pre-treatment questionnaire will need to be submitted to the Town of Barnstable’s Water Pollution Control Facility as part of the sewer connection permit process. Contact WPCF’s Kevin Follett (kevin.follett@barnstable.gov) for a copy of the pretreatment questionnaire. Any address changes will need to be coordinated with the COMM Fire Department and DPW Engineering department. The contact at the DPW is James Prygocki: James.Prygocki@barnstable.gov Any tree removal or plantings will need to be coordinated with the DPW Tree Warden, Andrew Bernier (Andrew.Bernier@Barnstable.gov). Any sidewalks damaged by construction activities will need to be replaced according to Town of Barnstable DPW standards. The sump pump for the elevator within the proposed 3-story multi-family building will not be permitted to discharge to the Town’s municipal sewage collection system and must be routed to the on-site stormwater management system. An additional easement will need to be created for the proposed sewer main connection to the existing collection system. All water mains/services will need to be sleeved in locations where minimum horizontal/vertical separation distance cannot be achieved between water and sewer mains/service lines. All sewer mains/services will need to be sleeved in locations where minimum horizontal/vertical separation distance cannot be achieved between stormwater and sewer mains/service lines. Depict the proposed elevation contours for the development site within the design plan set. Provide stop signs and lines the exit from the proposed development onto Great Marsh Road. Provide sight lines evaluating stopping sight distance for each direction of travel the exit from the proposed development onto Great Marsh Road. The Planning and Development Department has informed DPW that a traffic impact analysis/trip generation report is being submitted by the developer, upon receipt DPW will review and provide comment. Does the developer plan to construct sidewalks connecting the residences within the development to the proposed sidewalk extension along Phinney’s Lane/Route 28? Design plans and details depicting proposed connections to the municipal drinking water distribution system must be submitted to C.O.M.M. Water District for review and permitting. Provide ADA compliant handicap ramps with tactile warning panels at the driveway crosswalks shown along the proposed Phinney’s Lane sidewalk extension. The ZBA application package lacked sufficient information to evaluate the design of the development’s stormwater management system(s), the applicant will need to submit the following documents to DPW Engineering for their review. • The Massachusetts Stormwater Checklist completed and stamped by a Massachusetts Registered Professional Engineer (PE) • A complete Stormwater Report prepared and stamped by a Massachusetts Registered PE • Long-term Pollution Prevention Plan and Illicit Discharge Compliance Statement • Construction Period Pollution Prevention and Erosion and Sedimentation Control Plan • A narrative describing how the project will comply with standards 1 through 10 of the Massachusetts Stormwater Handbook and Stormwater Standards • Critical elevations for all proposed stormwater conveyances including swales, detention/inflltration basins, etc. • Drainage maps depicting pre and post-construction watershed boundaries, drainage areas and stormwater fiow paths, proposed analysis points and corresponding subcatchment boundaries, and off-site areas contributing to the proposed stormwater management system(s) • Calculations demonstrating the post-development peak discharge rates do not exceed the pre-development rates for the 2-yr and 10-yr 24-hour storms, and if off- site fiooding increases during the 100-year 24-hour storm, demonstrates post development peak discharge rates do not exceed pre-development rates for the 100-year 24-hour storm o THIS IS BASED ON THE MA SW HANDBOOK, DO WE WANT TO SPECIFICALLY INCLUDE THE 25-YEAR STORM? ONLY NOT INCLUDING BECAUSE THAT’S ALSO A TOWN REQUIREMENT? • Required recharge volume calculations • Soil testing documentation and soil analysis • Calculations conflrming inflltration best management practices (BMP)s will drain within 72 hours. • Calculations documenting the proposed stormwater management treatment trains meet the 80% TSS removal, and if applicable, the 44% TSS removal pretreatment requirement • Construction details and sizing for all components of the • A long-term Operations and Maintenance Plan (O&M Plan) covering all components of the proposed stormwater management system. Additional coordination will be required with TOB DPW and Planning and Development regarding the permitting, operations/maintenance, and ownership of the proposed stormwater collection system. Please let me know if either of you or the members of the board have any questions or comments related to our review. Best, Matt Wrobel, P.E.
