Revised Stormwater Management and Wetlands Protection MEMO-04-15-2016 \\private\dfs\ProjectData\P2011\0084\A71\NOI\NOI & SW Amendment\Revised Stormwater Management and Wetlands Protection MEMO.docx Corres. 78 Interstate Drive West Springfield, MA 01089 t 413.452.0445 800.286.2469 f 413.846.0497 www.fando.com Connecticut Massachusetts Rhode Island South Carolina April 15, 2016 Sarah LaValley City of Northampton Office of Planning and Sustainability 210 Main Street Northampton, MA 01060 RE: Village Hill Northview Lot Amendment to Notice of Intent & Stormwater Management Application Fuss & O’Neill Reference No. 2011 0084.A71 Dear Board members, On behalf of Kent Pecoy & Sons Construction, Inc., Fuss & O’Neill would like to submit an amendment to the Notice of Intent and Stormwater Management Application for the development of a 21 lot subdivision located on the former Hospital Hill Campus in Northampton, MA. The original submission was submitted on February 12, 2016. The project has been revised to remove all proposed work from the riverfront area and to reduce the wetland buffer work to adhere to the Northampton Wetlands Protection bylaws. The project was revised to remove two units from the within the 50 to 100 foot buffer to the bordering vegetated wetlands (BVW). The two units were moved to the east side of the site. A spur road was added to the east of the loop to provide access to the relocated units. In addition the large detention basin was moved northeast and regraded to remove disturbance within the 50 to 100 foot buffer to the BVW and the riverfront area. Revised Site Plans are attached. The revised project will meet stormwater standards required by the Massachusetts Stormwater Handbook and the City of Northampton Regulations. There is a slight increase in impervious area however the peak rates, ground water recharge, and water quality volume standards will still be met. Table 1 shows that peak rates for the site were reduced or maintained from existing to proposed. The Stormwater Management Report has been updated to reflect the changes made to the proposed project. The section below will replace the section in the original Notice of Intent and Stormwater Report. In addition attached figures and appendixes will replace the corresponding figures and appendices in the original Report.

This BVW is associated with a swale that follows an existing foot path. In addition there is a BVW located off-site that is associated with an unnamed perennial stream and Mill River. There is no proposed work within the existing BVWs. Per Section 337-10E (1)(a) of the Northampton Wetlands Protection, the Commission may allow the alteration of up to 20% of the area within the 50 to 100 foot buffer to the BVW. The total on site area within the 50 to 100 foot buffer is approximately 30,830 square feet. The proposed project will disturb approximately 6,069 square feet which is approximately 19.0% of disturbance. Although a large portion of the disturbance is to maintain access to a footpath and potential future multiuse path. 5.3 Riverfront There is an unnamed perennial stream located to the northwest of the project site. The mean annual high water line (MHW) was delineated by GZA GeoEnvironmental, Inc. and field surveyed by Sherman & Frydryk. Riverfront area is associated with the unnamed perennial stream. There is no proposed work within the riverfront area. 5.3.1 Riverfront Redevelopment Performance Standards This section can be removed. There is no proposed work in the riverfront area. 7.3.1 Existing Watershed Areas For the purpose of assessing pre-development hydrologic conditions the existing site was divided into three watershed areas. Figure 3 illustrating the existing conditions, existing conditions watershed areas, and the Tc paths. A schematic watershed diagram showing the discharge points and the breakdown of the ground covers characteristic for each watershed area is attached as Appendix C. Sarah LaValley April 15, 2016 Page 3 \\private\dfs\ProjectData\P2011\0084\A71\NOI\NOI & SW Amendment\Revised Stormwater Management and Wetlands Protection MEMO.docx Corres. 7.3.2 Proposed Watershed Areas For the purpose of assessing post-development hydrologic conditions the proposed site was divided into seven watershed areas. Figure 4 illustrates the proposed conditions, the proposed watershed areas, and shows the Tc paths. A schematic watershed diagram showing discharge points and the breakdown of ground cover characteristics for each watershed area can be found in the proposed hydrological calculations provided in Appendix D. The single-family building footprint sizes will vary slightly. For the purpose of the proposed model an average of 1,424 square feet was used. Standard #3: Stormwater Recharge The recharge volume is based on the existing soil conditions and the Recharge Target Depth by Hydrologic Soil Group (HSG) values provided in Volume 1 and 2 of the Massachusetts Stormwater Handbook. Total groundwater recharge required for the site is approximately 3,424 cubic feet. Groundwater recharge is provided by the proposed rain garden, the large subsurface infiltration located in the center green area and individual subsurface infiltration system for each of the single- family houses. Groundwater recharge provided by the proposed development is approximately 11,666 cubic feet. Groundwater recharge calculations are provided in Appendix F. Calculations for 72 hour drawdown are provided in Appendix F. As shown each of the stormwater infiltration BMPs will drawdown within the required 72 hours. Standard #4: Water Quality Water quality measures include a deep sump catch basin, a subsurface infiltration system and a rain garden. Each treatment train will provide the required 80% total suspended solids (TSS) removal rate. Pretreatment for each treatment train is provided as described below: • Pretreatment for the rain garden will be provided by a stone filter strip. • Pretreatment for the large subsurface infiltration system located within the center green area is provided by a deep sump catch basin. The TSS removal worksheets are located in Appendix G. A water quality depth of one inch was used. Total Required Water Quality for the site is approximately 5,707 cubic feet. Required Water Quality Volume is provided by the proposed rain garden and the subsurface infiltration system. The proposed project provides approximately 11,666 cubic feet of Required Water Quality. Required Water Quality calculations are provided in Appendix G.

Proposed improvements will occur within the buffer associated with two BVWs located on and off site. The proposed work including the access to the trail will disturb approximately 19.0% within the 50 to 100 foot buffer to the BVWs. There is no proposed alteration of the BVW. There is no work proposed within the riverfront area. The redevelopment project has been designed to meet the Massachusetts Stormwater Handbook and the Northampton Chapter 281 Stormwater Management Regulations. Sincerely, Reviewed by: Jon Allard, L.A.
