28 The Residences at Alewife Station Site Improvements

29 Site Improvements In accordance with the Massachusetts Wetlands Protection Act (WPA) 310 CMR and the Stormwater Management Handbook guidelines for Redevelopment Projects, the project analyzed the following existing and proposed conditions: Impervious & Pervious Groundcover Areas Stormwater Management & Water Quality Treatment 100 Buffer to Bordering Vegetated Wetlands Land Subject to Flooding (Resource Area)

30 Existing Site Conditions Lot Area = 3.8 acres Impervious Area = 92.9% Minimal Stormwater Treatment Small Portion of lot located within 100-foot wetland buffer Located within FEMA 100-year Floodplain

31 Impervious & Pervious Groundcover Areas Existing Site = 3.8 acres Impervious Area = 3.6 acres (93%) Proposed Impervious Area = 2.6 acres (70%) Project adds nearly one (1) acre of new pervious area

32 Stormwater Management & Water Quality Treatment The project will employ natural & structural Best Management Practices (BMPs) to manage & treat stormwater runoff: Wet Pond Rain Garden Catch Basins (Deep Sump w/ Hoods) Water Quality Treatment Units (i.e. Stormceptor or approved equal)

33 Bordering Vegetated Wetlands on Adjacent Site

34 100 Buffer to Bordering Vegetated Wetlands Existing Total Buffer Area = 13,248 sf Impervious Area = 9,630 sf (73%) M o t e l Proposed Impervious Area = 4,900 sf (37%) Proposed Building Parking Lot Wet Pond Project significantly reduces impervious surface in buffer area

35 Land Subject to Flooding Design based upon current FEMA floodplain mapping for 100-Year Storm Event AND the City of Cambridge Climate Change Vulnerability Assessment (CCVA) Projections for 2030 & year storms Recommendation to design to 2030 projection and show ability to recover from 2070 projection

36 Existing Conditions Existing 100-Year FEMA Floodplain Cambridge Gateway Inn Lanes and Games FEMA 100-year Flood Elevation = 6.8 3,748 CY of Existing Flood Storage

37 Existing Conditions Projected Year Floodplain CCVA s Estimated year Flood Elevation = 7.5 6,276 CY of Existing Available Flood Storage

38 100-Year FEMA and 2030 Floodplain Mitigation

39 Proposed Conditions 100-Year FEMA Floodplain FEMA 100-year Flood Elevation = 6.8 Underside/Bottom of Garage Slabs located at elevation 7.5 4,172 CY of Available Flood Storage Created Project provides an additional 424 CY of Available Flood Storage

40 Proposed Conditions Proposed Year Floodplain Estimated 100- year Flood Elevation = 7.46 Parking garage slabs set at 7.5 ; building lobbies set at elevation 8.5 7,174 CY of Available Flood Storage Created Project provides an additional 898 CY of Available Flood Storage

41 Proposed Conditions Proposed Year Floodplain Estimated 100-year Flood Elevation (Based upon Estimated Sea Level Rise AND Storm Surge = NAVD Key Building Elevations: Underside/Bottom of Parking garage slabs - Elevation 7.5 NAVD Building lobbies & first floor amenity space - Elevation 8.5 NAVD Residential Units Approximate Elevation 21.0 NAVD Building Ground floor space (lobby & amenities area) and Parking Garage Entries will utilize flood gates at openings during forecasted 100- Year Storm Events and other major storm events.

42 Site Improvements Summary Impervious & Pervious Groundcover Areas Replaces almost an acre of impervious area with pervious area Stormwater Management & Water Quality Treatment - Significant improvements over existing conditions; including reduction in peak flows & water quality treatment 100 Buffer to Bordering Vegetated Wetlands Impervious area in the buffer zone will be reduced by almost 50% Stormwater runoff captured and treated prior to discharge to adjacent wetlands Land Subject to Flooding Increases onsite flood storage capacity Meets the recommendations of the City s Climate Change Vulnerability Assessment Accommodates the yr flood projection and able to recover from 2070 projection
