Item Christina Basin Trends, 1995-2010(2010-12-22) Kauffman, Gerald; Homsey, Andrew; Corrozi Narvaez, Martha; Chatterson, Sarah; McVey, Erin; Mack, StaceyThis report summarizes trends in the Christina Basin from 1995-2010 for (1) population, (2) land use, (3) water quality, (4) population/water quality vs. land use, (5) water temperature, and (6) streamflow. The Christina River Basin, the second largest tributary to the Delaware Estuary, lies in Chester County, Pa., and New Castle County, Del., with a small sliver in Cecil County, Md. The Christina Basin has unique interstate coordination challenges, as it is the only watershed in the entire Delaware Basin that includes more than one state. Since 1994, Delaware, Pennsylvania, the EPA, and the Delaware River Basin Commission have been working together to restore the Brandywine, Red Clay, and White Clay Creeks and Christina River to fishable, swimmable, and potable status (as per the Federal Clean Water Act) and state surface-water quality standards through a phased watershed-restoration approach.Item Economic Value of the Delaware Estuary Watershed - Summary Document(2011-06-29) Kauffman, Gerald; Homsey, Andrew; Chatterson, Sarah; McVey, Erin; Mack, StaceyWhat do Boeing, Sunoco, Campbell’s Soup, DuPont, Wawa, Starbucks, Iron Hill Brewery, the Philadelphia Eagles, Salem Nuclear Power Plant, and the United States Navy have in common? They all depend on the waters of the Delaware Estuary to sustain their business. The natural resources of the Delaware Estuary watershed provide tremendous economic value to our region. This report examines that value in three distinct ways: • Economic value directly related to the Delaware Estuary’s water resources and habitats: Using economic activity as a measure of value, the Delaware Estuary contributes over $10 billion in annual economic activity from recreation, water quality and supply, hunting and fishing, forests, agriculture and parks. • Value of the goods and services provided by the Delaware Estuary’s ecosystems: Using ecosystem goods and services as a measure of value, the ecosystems of the Delaware Estuary (such as wetlands, forests, farms, and water) provide $12 billion annually in goods and services in 2010 dollars, with a net present value of $392 billion calculated over a 100-year period. • Employment related to the Delaware Estuary’s water resources and habitats: Using employment as a measure of value, the Delaware Estuary directly and indirectly supports over 500,000 jobs with over $10 billion in wages annually. This does not include the thousands or even millions of jobs in companies and industries that rely on waters of the Delaware Estuary for their industrial and commercial processes.Item NPDES and Education on Stormwater Pollution(2012-06-27) Corrozi Narvaez, Martha; Homsey, AndrewControlling and managing stormwater that runs off roadways―impervious surfaces―into the state’s surface waters are a major part of DelDOT’s responsibilities. As authorized under the Clean Water Act, the National Pollutant Discharge Elimination System (NPDES) controls water pollution by regulating stormwater that discharges directly into surface waters. New Castle County, DelDOT, and six municipalities—Bellefonte, Delaware City, the Town of Elsmere, the City of Middletown, the City of New Castle, and the City of Wilmington—are Phase I co-permittees for the discharge of stormwater from and through all portions of the municipal separate storm-sewer system (MS4) in New Castle County as authorized under the NPDES and the laws of the State of Delaware. In order to meet the requirements of the NPDES permit, the co-permittees (named above) must meet specific education and outreach requirements outlined in the NPDES permit. This report provides guidance for DelDOT and the co-permittees for achieving the education and outreach requirements of the NPDES permit. It intends to make the education and outreach efforts more effective and meaningful for New Castle County, DelDOT and the six municipalities regulated under the permit.Item Southern New Castle County Priority Watershed Strategy(2006-09-01T18:45:16Z) Homsey, Andrew; Kauffman, Gerald; Schnick, LoriThis report provides a recommended priority watershed strategy for the streams in southern New Castle County, Delaware. This strategy is designed to be consistent with the (1) total maximum daily loads (TMDL) issued for the Appoquinimink River watershed by the USEPA and the Delaware Department of Natural Resources and Environmental Control (DNREC), (2) proposed revisions to the environmental protection articles of the New Castle County Unified Development Code (UDC), and (3) the 5-year New Castle County Comprehensive Plan Update currently underway. The priority watershed strategy concludes that the resource protection level (RPL) standards of the New Castle County UDC are adequate to protect water resources and natural resources in southern New Castle County at full build-out with current zoning in effect. The contiguous chain of watersheds lining the Chesapeake and Delaware Canal, the Delaware Bay coast, and the Blackbird forest and wetland complex with low impervious cover and large amounts of forest, wetland and riparian buffers create an emerald ring around the rapidly growing towns of Middletown, Odessa, and Townsend (MOT) in southern New Castle County. These green watersheds should be protected from over-development by acquiring more open space and conservation easements, thus creating an unbroken ring of conservation open space-a green belt-around the periphery of the MOT village core.Item Technical Summary: State of the Delaware Basin Report(2009-01-16T20:01:56Z) Kauffman, Gerald; Belden, Andrew; Homsey, AndrewFor many environmental indicators, the health of the Delaware River Basin has improved or at least remained stable in many watersheds, even in the face of an industrial legacy, increased land development, a growing population, and rising thirst for water supplies.This report defines environmental indicators for the State of the Delaware River Basin project. Indicator data were collected by a collaboration among the Delaware River Basin Commission, Partnership for the Delaware Estuary, U.S. Environmental Protection Agency (USEPA), U.S. Geological Survey, and a consortium of the four land-grant universities that represent the states in the basin—Cornell University, Pennsylvania State University, Rutgers University, and University of Delaware.Item White Clay Creek State of the Watershed Report: A Report Card on the Health of the White Clay Creek Wild and Scenic River Watershed in Delaware and Pennsylvania(2009-01-20T18:39:56Z) Corrozi, Martha; Homsey, Andrew; Kauffman, Gerald; Farris, Erika; Seymour, MaureenThe White Clay Creek watershed is rich in natural resources and history and provides numerous benefits to people. However, increasing suburbanization and legacy pollutants threaten to degrade the ecological landscape of the White Clay Creek. The University of Delaware Institute for Public Administration’s Water Resources Agency has reviewed 21 environmental indicators to assess the state of the White Clay Creek watershed. These indicators are divided into four major categories: landscape, hydrology, water quality, and habitat.
