Newtown Creek Funding Opportunity Site: Laguardia Community College. Parking Lot Redesign Proposal. Project Overview. Scope: Redesign Laguardia Community College’s parking lots 2 & 3 (19,000 sf ) in accordance with NYSDEC Stormwater BMPs. Primary Goals:
Parking Lot Redesign Proposal
Reduce stormwater runoff by:
Stormwater Runoff Calculations
Existing Runoff from Lots 2 & 3 (gallons/year) 497,241
Proposed Runoff from Lots 2 & 3 (gallons / year) 183,194
Net Proposed Captured Water for Lots 2 & 3 (gallons/year) 314,047
Combined sewer outfalls in New York City flood during half of all rainstorms, discharging approximately 27 billion gallons of wastewater in an average rainfall year.
From NYCDEP Publication: New York City’s Wastewater Treatment System
DEP devised a three-pronged approach – an immediate, an interim, and a longterm program – to administer 1,200 wet tons of sludge produced each day.
($670M) - The first facility went on line in December 1991. The other seven were finished and became operational by June 1992.
$100M/YR, ($500M) - Three contractors were hired through five-year contracts to provide land-based biosolids management. The contractors were responsible for the processing, production and shipment of biosolids as high-quality soil amendments and the application thereof.
$50M/YR, ($750M) - The long-term program currently costs, and includes three 15-year contracts that were let for the city’s entire biosolids production through June 2013.
Total Costs from 1991-2013 for Sewage Treatment: $1.92 Billion
Cost per year for Sewage Treatment: $83.5M
Cost per day for Sewage Treatment: $.23M
NYCDEP / Riverkeeper, 2005b
New York City's plants treat about 1.4 billion gallons of wastewater from homes, businesses, schools, and streets in the five boroughs every day (NYCDEP).
The total dry weather capacity of New York City’s sewage treatment plants is 1.8 billion gallons per day (Riverkeeper, 2005b).
NY Times Superfund Cleanup Costs Article
Scrubbing more than 150 years of industrial pollution in the Gowanus could cost up to $500 million, with Newtown Creek -- which is more industrialized and a mile-and-a-half longer than the Gowanus -- expected to cost still more.
Cost per gallon of sewage treatment in NYC:
$.23M/1400M gallons = $164/gallon
$.23M/1,800M gallons = $128/gallon
(164+128)/2 =AVG $146/gallon
Assuming the proposed design will reduce the amount of stormwater runoff from the site by 314,047 gallons, the amount of annual savings in terms of water treatment costs are:
314,047 gallons/year x $146/gallon = $46M/year
Pollution Externalities: devastate the ecosystem, severely affect economic value of adjacent waterway properties, reduce usage of waterways for recreation or fishing, pose direct (direct contact) or indirect (through consumption) health hazards.
Scrubbing more than 150 years of industrial pollution from Newtown Creek is expected to cost more than $500M.
