- ItemEconomic Value of the Maryland Coastal Bays Watershed(Water Resources Center, 2018-05-23) Kauffman, Gerald J.; Young, Jillian; Martin, Jordan; Homsey, Andrew R.The water, natural resources, and ecosystems in the Maryland Coastal Bays watershed contribute an economic value of $1 to $3 billion annually to the regional Delaware, Maryland, and Virginia economy. This report examines that economic value in three different ways: 1. Economic value directly related to the Maryland Coastal Bays watershed water resources and habitats. The Maryland Coastal Bays watershed contributes over $1.2 billion in annual economic activity from water quality, water supply, fish/wildlife, recreation, agriculture, forests, and public parks benefits. By state, Delaware, Maryland, and Virginia contribute $200 million, $700 million, and $300 million, respectively, to the Coastal Bays watershed annual economy. 2. Value of goods and services provided by the Maryland Coastal Bays watershed ecosystems. Using natural capital as a measure of value, habitats in the Maryland Coastal Bays watershed provide $3 billion annually in ecosystem goods and services in 2017 dollars, with a net present value (NPV) of $97 billion calculated over a 100-year period. By state, the ecosystem services value of the watershed is $248 million in Sussex County, Delaware; $1.9 billion in Worcester County, Maryland; and $807 million in Accomack County, Virginia. 3. Employment related to the Maryland Coastal Bays watershed resources and habitats. Using employment as a measure of value, natural resources within the Maryland Coastal Bays watershed directly and indirectly supports over 50,000 jobs with over $1.5 billion in annual wages. The purpose of these estimates is to demonstrate that the Maryland Coastal Bays watershed provides real and significant economic benefits to the regional economy in Delaware, Maryland, and Virginia and are worthy of investment to keep these natural resources healthy and productive. Estimates were made by taking values from existing literature and studies and applying them to the Maryland Coastal Bays watershed using ecological economics and benefits-transfer techniques described in this report. Values are converted to 2017 dollars based on the change in the Northeast Region Consumer Price Index except where noted.
- ItemShad 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.
- ItemEconomic Value of the Barnegat Bay Watershed(2012-11-21) Kauffman, Gerald J.; Cruz-Ortiz, CatherineThis report summarizes the economic value of water, natural resources, and ecosystems in the Barnegat Bay watershed in Ocean County and Monmouth County, N.J., estimated as: 1. Economic activity including market and non-market value of water quality, water supply, fish/wildlife, recreation, agriculture, forests, and public parks benefits. 2. Ecosystem goods and services (natural capital) value provided by habitat such as wetlands, beaches, open water, forests, and farms. 3. Jobs and wages directly and indirectly associated with the Barnegat Bay watershed. These estimates demonstrate that the Barnegat Bay watershed provides significant economic benefits to the regional economy and are worthy of investment to keep them healthy and productive. Value-transfer techniques were applied by selecting data from published literature and applying them to the Barnegat Bay watershed using ecological economics techniques.
- ItemNPDES 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.
- ItemEconomic 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.
