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 Benefits and Jobs Provided by Delaware Watersheds(2012-01-31) Corrozi Narvaez, Martha; Kauffman, GeraldThe water, natural resources, and ecosystems contained in Delaware’s watersheds are an economic engine for the state. These resources provide tremendous economic value to the state and the surrounding region. This report examines that value in three distinct ways: • Economic value directly related to Delaware’s water resources and habitats—Using economic activity as a measure of value, Delaware watersheds contribute over $6 billion in annual economic activity from water quality, flood control, water supply, fishing and wildlife viewing, recreation, agriculture, ports, forests, and parks. • Value of the goods and services provided by Delaware’s ecosystems—Using ecosystem goods and services as a measure of value, the ecosystems of Delaware provide $6.7 billion annually in goods and services in 2010 dollars, with a net present value of $216.6 billion calculated over a 100-year period. • Employment related to Delaware’s water resources and habitats—Using employment as a measure of value, Delaware’s water resources and habitat directly and indirectly support over 70,000 jobs with over $2 billion in wages annually. This does not include the thousands or, perhaps, millions of jobs in companies and industries that rely on Delaware’s waters 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 Quantifying Load Reductions of Selected Pollutant Parameters Through the Use of Stormwater Best Management Practices in the Delaware Portion of the Christina Basin(2009-08-25T17:35:49Z) Homsey, Andrew R.; Corrozi Narvaez, Martha; Farris, Erika D.; Nelson, Maureen H.S.At the request of the Delaware Department of Natural Resources and Environmental Control (DNREC), the Water Resources Agency (WRA), a unit of the University of Delaware’s Institute for Public Administration, developed a process to quantify load reductions achieved through stormwater-control structures (best management practices, or BMPs) for selected pollutant parameters in the Delaware portion of the Christina Basin. This report summarizes the scope of the project and outlines the methodology, analysis, and implications.Item Restoration of Shad and Anadromous Fish to the White Clay Creek National Wild and Scenic River: A Feasibility Report(2010-12-22) Corrozi Narvaez, Martha; Kauffman, Gerald J.; Lonsdorf, Robert; Nelson, Maureen H.S.The long-term goal of the White Clay Creek watershed project is to restore shad and migratoryfish passage and habitat, increase spawning areas, and benefit the resident fish in the 107-sq.-mi. watershed. To achieve this, WRA conducted a feasibility study for restoring fish passage to the federally designated National Wild and Scenic White Clay Creek. This project is funded by the National Fish and Wildlife Foundation (NFWF) and is one of 17 projects being undertaken by a number of regional organizations that are striving to improve the environment of the Delaware Estuary— the tidal portion of the Delaware River.Item Shad in Schools Christina Basin Program Report 2010-2012(2014-05-23) Corrozi Narvaez, Martha; Lucas, TimThe intent of this report is to summarize the program and commitment to implement the Shad in Schools program in the Christina Basin. This program is part of the broader education efforts to educate students and the public on the shad restoration efforts in the White Clay and Brandywine Creeks. The Shad in Schools program provides an experiential learning opportunity to students in the Christina Basin watersheds. It brings fish and their habitat into the classroom and serves to teach students about important environmental concepts related to water quality, ecosystems, biology, chemistry, and many others. In addition, this program incorporates history, art, public speaking, and other non-science disciplines.Item Synthesis of Water Rates in Delaware and Contiguous States(2009-08-18T20:24:11Z) Corrozi Narvaez, Martha; Nelson, Maureen H.S.The University of Delaware Institute for Public Administration’s Water Resources Agency (WRA) conducted an inventory of water rates for public and investor-owned water utilities within Delaware and its bordering states—Pennsylvania, New Jersey, and Maryland. This report summarizes and compares the residential water rates for these four states and is intended to serve water purveyors, the public, and federal, state, and local decision-makers. This report is an update of the original water-rate inventory prepared in September 1996 and later reports—Economic Synthesis of Water Rates in Delaware and Surrounding River Basins (August 21, 2000) and Synthesis of Water Rates in Delaware and Contiguous States (July 2004).
