The Cornell Cooperative Extension of Suffolk County will map and catalog the stormwater structures in the Carmans River watershed area, according to the Town of Brookhaven.
Stormwater structures include catch basins, recharge basins and outfall pipes. The extension service will collect data using electronic geographic information systems to record the precise location, depth, diameter, material and structure cover of each stormwater structure.
“This is another step to our ultimate goal, which is to protect and preserve the water quality of the Carmans River,” Town Supervisor Mark Lesko said in a news release.
The town will pay $65,000 for the work.
Lesko noted that some of the structures were installed more than 50 years ago and should be checked for their working condition.
In addition, the town must map all of its stormwater structures by May 2015 as part of its state Department of Environmental Conservation permit.
The Carmans River, which runs from Middle Island to Bellport Bay, is slated for an environmental protection plan that would restrict future building near the river while allowing greater density on about 10,000 acres of commercial and industrial lands elsewhere in Brookhaven.
Property owners near the river would be able to sell so-called development credits to developers, who could use them to build elsewhere with greater density than allowed by current zoning.
