Matt Bearse Luke White Nate Whetten Mark Grylls Nalin Mistry Project Summary Construct swimming pool, modify existing parking layout and entrance driveway. Comments leBuilding: Modification of the parking lot that does not fully comply with all applicable sub sections of sections 301 requires a special permit per section 301.2. Parking spaces to dimensionally comply with section 301.4.2. (10'x20')Additional in lot trees required per section 301.4.6. Lighting plan not provided to indicate compliance with section 301.4.10. Construction shall comply with all applicable sections of 780 CMR and 521 CMR. In addition to 780 CMR, pool barrier to comply with MGL. Ch. 140 § 206. Pool location will require a variance from the ZBA per Zoning Bylaw section 203.5. 'C Jommunity Development and Planning: 1. Pool-Water Slides/Stone Structure: Proposed pool located in the front next to Route 28 is not ideal. Applicant has indicated this was done due to the need to locate the new septic system further into the property. 2. Landscaping: Landscape Plan should clearly depict the existing buffer trees/plantings to remain and the proposed plantings. There appears to be a symbol for a plant not included in the legend. All plantings to be native to the south coast of MA, Cape cod &the Islands. Applicant indicated plantings on top of new septic system will be in planters. a. Buffer Trees (min. 3" caliper): Existing front buffer trees should remain, add additional buffer trees along Route 28 and add tree in the front buffer on the east side of the driveway. 3. Parking: The new 18 space lot is only about 54' wide, not sufficient for perpendicular parking and does not meet bylaw. Applicant confirmed that vehicles can drive over or park on top of the septic system. 4. Pedestrian Access: Identify clear pedestrian routes from parking (including handicap parking) to front building and pool. General: There are no grades, drainage, or water services shown on the plans. Septic is shown as a very light box with no labels. Conservation: • A work limit line of silt fence or a similar erosion control method is required along the 35-foot buffer line, as the area behind it is a NO disturb zone. • No new pavement can be proposed within the 50' buffer without 2:1 mitigation plantings • Greater than 1 acre of disturbance is present on this property and therefore will require a Stormwater Management Permit Application Design Review: The project requires design review which is being scheduled. Engineering: 1. General: 4 a. What is the status of Sheet C2.1.1 (dated 3/20/22) as approved by the Health Department related to proposed drainage? Has it been installed? It is not reflected on Sheet 3 on the current submission. 2. Drainage: a. Total proposed disturbance (including portions of the site currently under construction) is greater than 1 acre. Stormwater Management Site Plan (SMSP) is required. i. As part of that submission, refer to the following comments on initial review: 1. Provide drainage calculations for the proposed stormwater infiltration systems demonstrating that the capacity of the proposed leaching chambers is sufficient for the proposed flows. 2. Provide operations and maintenance plan including existing and proposed drainage systems and pool discharge. 3. It is unclear which drainage is existing or scheduled to be replaced. Any existing drainage must be cleaned, inspected and repaired as needed. If existing drainage doesn't have adequate sumps, it should be replaced with a 4' sump. 4. Show the proposed leaching chamber layout, depth, piping connections and structural details for all components of the systems. 5. Detail illustrates the pool & patio drainage from 226 Route 28 connecting to the mechanical room below 216 Route 28. Where does this stormwater/ pool discharge end up? 6. Drainage areas are not covering the rear of the buildings. 7. Clarify where roof run off discharges to. 3. Site improvements: a. Provide pavement profile detail for new paving areas. b. Provide limits of new parking areas. c. Provide emergency vehicle turning radius for site.
