Project Proposal Summary We are proposing an onsite and right of way project linking a private blue roof to both intensive active and passive right of way sidewalk bioswales at 92 3rd Street in the Gowanus Canal watershed in Brooklyn. To come: list all green infrastructure technologies that are being proposed [ approximate timeline budget summary Stormwater calculations summary Costs per gallon summary C. Project Details C.1 Project Description Current Stormwater Problem, CSOs and Water Quality in the Gowanus Canal The Gowanus Canal 1.5 mile long man made canal. At a low point of valley landform, is a 6-square mile watershed for surrounding areas including the Carroll Gardens, Cobble Hill and Park Slope neighborhoods. The Gowanus Canal community is one of several combined sewer overflow hotspot regions throughout the City as described by numerous reports including the GWP (2004) and most recently the EPA Remedial Investigation report released in Combined sewers (i.e., sewers that receive both sewage and stormwater flows) serve 92 percent of the Gowanus Canal watershed, storm sewers serve only 2 percent, and direct runoff drains 6 percent of the watershed (NYCDEP, 2008a). During wet weather, runoff enters the combined sewers and exceeds the capacity of the system when an appreciable rate of rainfall occurs. There are two combined sewer systems in the watershed that overflow to the canal: the Red Hook and Owls Head water pollution control plants (WPCPs). Between these systems, there are 12 permitted CSOs to the study area; 10 are active. In addition, there are three known stormwater outfalls discharging to Gowanus Canal. Some of the greatest annual CSO discharge volumes come from RH-035 at the intersection of Bond and 4th Streets, immediately proximate to our site. The 3G project covers the blockwide region bounded by Hoyt, Bond, 4th and 3rd Streets and directly treats the GC-CF-W CSO outfall. (See map below) Living City Stormwater Pilot DEP Green Infrastructure Grant Program 2

3 Largely due to the high volume of these discharges and subsequent water quality deterioration, in 2004, the Gowanus Canal was included by the NYSDEC on the New York State Section 303(d) list of impacted waters and was included within the New York State Section 305 (b) report as required by the Federal Clean Water Act because fish propagation was affected by oxygen demand that resulted from urban storm runoff and CSO discharges. The primary goal of the DEP s City-Wide Long Term CSO Control Planning Project is to reduce these CSO effects through the continued implementation of programmatic controls that can be effectively monitored. Ultimately the goal is to achieve a water quality level of saline Class D, a classification suitable for fishing and fish survival. Additionally, the Gowanus Canal has been identified by the United States Environmental Protection Agency (EPA) as one of eight Urban River Restoration Initiative (URRI) Pilot sites in the United States. The Living City Stormwater Pilot was designed as a one component of a larger 3rd Street Green Corridor plan responding to these challenges and goals. We believe the project has added impact being part of a broader landscape of water quality targets and infrastructure improvements being carried out by multiple agencies. Green Infrastructure Project Approach The proposed project seeks to reduce the volume of stormater runoff flowing to CSSs connected to the RH-035 outfall of the Gowanus Canal sewershed by implementing innovative stormwater control systems at a commercial property in the sewershed. For this project we will be directing both sidewalk stormwater runoff and metered roof water from a blue roof system to both conventional intensive sidewalk bioretention swales and controlled underdrain bioretention systems to demonstrate the positive infiltration and water quality performance increment associated the active control of a bioretention cell s underdrain pipe. For example, towards the end of a precipitation event when inflow to the system is tailing off, water level monitoring within the bioretention swale will inform autonomous system control routines to allow for closing of the underdrain valve, extending retention times to allow for enhanced water quality and more time opportunity of infiltration to surrounding soils.

4 The proposed project will demonstrate the efficacy of two important concepts: 1) the performance benefits associated with linking rooftop detention with streetscape bioretention, where runoff from roof surfaces which is typically connected to the City s combined sewer system is redirected to street-side bioretention to introduce benefits of retention/detention and water quality enhanced by the two system s integration, and 2) controlled underdrain bioretention, where the water quality and recharge benefits of typical retention/detention systems are augmented by introducing forecast-specific retention control. The integration of surface features such as bioretention with roof-top detention provides for extended time-to-concentration of storm flows from the roof, allowing for more time-distributed inflows to the bioretention system and better overall performance.

5 in the project planning. Approval to construct and operate the proposed system has been provided by Peter Moore. Property ownership documents are provided in Attachment x Third Street, situated on the south side of the street, are part of a set of five connected buildings making up a single commercial redevelopment site. The site is located in Gowanus, Brooklyn, in NYCDEP Community District 6, ith a Median HH Income of $67,538, but nearly 20,000 people living below the poverty level. The area is a dense, urban community of mixed commercial, industrial, municipal and residential land use. Current Uses of Proposed Project Area The site is a commercial property and public sidewalk. The building is being redeveloped to include community amenities including shared office spaces, artist studios, restaurant, retail, and a small boutique hotel space. The combined buildings currently houses three small businesses, but most of the square footage is vacant, including the floor below the blue roof area. Third Street is a high-trafficked corridor between Carroll Gardens and Park Slope. There is active car, bicycle and foot traffic. Description of Existing Sewer Connections and Any Active Detention Systems [phil] Expected Impacts on Current Usage The project is positioned to greatly enhance the property. The bioswale represents significant beautification of a historically industrial block that currently has struggling street trees and no other green features across [x feet of ] a double wide sidewalk. The blue roof-decking system is meant to demonstrate stormwater systems that work in concert with and enhance usable space. The roof will be an active event space. The construction will not interfere with existing work in the building and will have [xyz] impact on sidewalk traffic. Feasibility Studies/Analysis?
