GRANT PROGRAM
BY EMMA TAMLIN, ASSISTANT EDITOR

In New York City, an estimated 20 billion gallons of
sewage and polluted stormwater runoff flows into
the Hudson River and other waterways each year.

N

ew York City recognizes the value of green infrastructure and the Department of Environmental Protection (DEP) has budgeted $1.5 billion for green infrastructure to reduce
combined sewer overflows (CSOs) and improve water quality by 2030. The challenge they
face is that as much as 50 per cent of the land in priority areas where CSO's occur is owned
by the private sector and the DEP is running out of places to build bioswales.
Despite the numerous approaches to managing stormwater, green roofs have become a top
priority for the DEP and highly regarded by City Councilors. "Green roof investments pay dividends not just for building owners, but for the city and the environment as a whole," said Manhattan Borough President Gale A. Brewer. Congressman Joe Crowley (D-Queens, the Bronx),
Chairman of the House Democratic Caucus says "Our city's roofs are an untapped resource in
reducing stormwater runoff and making our homes more energy efficient".
During the CitiesAlive Conference in 2015, city officials received criticism about difficulties in
accessing funding under the existing grant program. Since then, the Natural Resources Defense
Council and NYU Stern Center for Sustainable Business conducted extensive research for the
DEP on how to better leverage the private sector for green infrastructure implementation. Catalyzing Green Infrastructure on Private Property: Recommendations for a Green, Equitable and Sustainable New York City was published in 2017. The report contains recommendations for the creation
of a new grant program that is transparent, simple and flexible, and the restructuring of water and
sewer rates to include a separate stormwater fee and create strong rules that require stormwater
management.
On Earth Day 2018, the DEP announced that the Green Infrastructure Grant Program
would now offer a streamlined funding schedule for green roof projects. The goals of the new
grant program revisions are to incentivize more private property owners to install a green roof by
streamlining the approval process. Green roof funding is now determined by green roof area and
growing media depth, where projects with 4 inches or more in growing media depth can earn up
to $30 per square foot.
CitiesAlive 2018 returns to NYC in September to further the conversation and bring the design, research and policy communities together. Melissa Enoch, the Program Manager for Private
Incentives at the NYC DEP, will be presenting "Framework for a Performance-Based Green
Roof Incentive Program in New York City" to draw attention to the need to develop a green
roof incentive framework that accounts for differences in green roof performance and maximizes
incentive cost effectiveness.
