Cambridge Harbor

10,000

Cambridge is located on the Choptank River about 70 miles southeast of Baltimore, Maryland. In 1963 the Maryland Port Authority with a grant of $500,000 from the Area Redevelopment Administration provided a turning basin and a channel 25 feet deep in Cambridge Harbor. The grant did not include funds for maintenance. The study will determine the advisability of having the United States assume responsibility for maintenance of the 25-root channel and turning basin. Maintenance of the channel and turning basin will result in incremental transportation savings.

A study to determine the feasibility of modifying the existing Federal channels from the Atlantic Ocean to the Port Elizabeth-Port Newark terminals, which are located in New Jersey adjacent to Newark Bay. They are served by Federal waterways from deepwater in the Atlantic, including Ambrose Channel, Kill Van Kull and Newark Bay Channel with depths of 45 feet, 35 feet and 35 feet respectively, all at mean low water. Cargo handled at the Port Newark-Port Elizabeth terminals is expected to exceed 16 million tons in 1973. Since authorization of the project waterways serving the terminals, there has been a dramatic growth in the size of vessels being used in the container trade. Vessels expected to be placed in operation in mid-1974 at the Port Newark-Port Elizabeth complex will have lengths in excess of 940 feet, widths of 105 feet and drafts of 33 feet. Future sizes of container vessels are expected to be even greater.

A study to determine the advisability of improvements in the interest of flood control, navigation, water supply, recreation, and other allied purposes, with due consideration to preserving and enhancing the environmental values of the basin. The Schuylkill River, which drains an area of 1,916 square miles, is a major tributary of the Delaware River located in southeastern Pennsylvania. It joins the Delaware River in Philadelphia. The lower 8.6 miles in Philadelphia are navigable. The presence of natural obstacles in the river and tributaries, deterioration of locks and dams, and with few exceptions, the lack of general recreational facilities, are the major deterrents to a more active use of the river for navigation and its banks for recreational use. Industrial, commercial, and residential flood damages in the basin average over $1,400,000 annually. Severe flood damages were experienced throughout the watershed in June 1972. Damages are estimated to have approached $200,000,000. Water quality in the river has deteriorated, and there is a need for additional water supply. Poor water quality has led to the lack of widespread water use, particularly for water contact sports such as boating and swimming.

This study covers the City of Virginia Beach which is located in the southeastern corner of Virginia. The 40-mile shoreline abuts the Atlantic Ocean and Chesapeake Bay and includes a highly developed resort area along a portion of the ocean shore. The northern part of the City is being rapidly subdivided for residential purposes. The extremely low and flat topography in the City of Virginia Beach makes it susceptible to considerable flooding, particularly during heavy rains which result in large property losses and serious health hazards in newly developed residential areas. Some flooding occurs during minor storms. The study has considered a master drainage plan consisting of canals to relieve flooding conditions and to provide for recreational boating all in the interest of the rapidly growing population. The study has also considered jetty improvement or other means of preventing the rapid shoaling being experienced in the existing non-Federal navigation channel at Rudee Inlet. Interim reports will be completed during fiscal year 1974 for one drainage canal and improvements to Rudee Inlet.

This study will develop a complete water and related land resources plan for a portion of the Wilmington, Delaware, Standard
Metropolitan Statistical Area, with a total urban population of 500,000 (1970). The study area encompasses the entire
Christina River Basin including the Brandywine Creek Watershed, with a total drainage area of 565 square miles.
A plan
of study is being developed in cooperation with all concerned local, State and Federal interests so as to avoid duplication
and to take advantage of completed and on-going planning efforts. This will be a cooperative study to identify present
and future water resources needs, with particular emphasis on urban water resources needs, as well as the immediate
flood problems. The first major study effort will focus on the development of acceptable, certifiable, implementable
waste-water management solutions to carry out the intent of the Federal Water Pollution Control Act Amendments of 1972,
Public Law 92-500. Moreover, the overall study will include analysis of flood problems of both an urban and rural nature,
as well as the recreational, water supply, and water quality needs of the study area.

The problems associated with the Christina River Basin have grown with the population. The study area encompasses two
of the fastest growing counties in the area; Chester County (Pennsylvania) and New Castle County (Delaware). Flood
problems currently exist along the Christina River, Mill Creek, White Clay Creek, Red Clay Creek in the State of
Delaware, and along the Brandywine Creek in Pennsylvania and Delaware. Inadequate drainage facilities in developing
population centers have compounded the problem in the urban areas.

Presently, the water supply for the population and industries of the Christina River Basin is principally from
surface waters, supplemented in certain areas with wells. High yield aquifers are limited and isolated in the basin.
The significant water quality problems in the area result from sediment concentrations, discharges from municipal
and industrial facilities, natural inorganic contributions and agricultural pollution from fertilization and
pesticidal applications.

A study to determine the need for modifying the existing projects or adopting additional projects for flood control on
the Hoosic River. Although local flood protection projects have been constructed at Adams and North Adams, there are
still significant flood damages in the basin. It is estimated that a recurrence of the flood of December 1949 would
cause damages of about $3,300,000 in the basin. Local interests have expressed a desire for the extension of the
existing Adams project to tie in with the North Adams project, a distance of three miles. Portions of the basin in
Vermont and New York were declared a disaster area as a result of the June 1973 storm.

This study will lead to development of a complete water and related land resources plan for the Counties of Burlington,
Camden and Gloucester, New Jersey. The study area, which comprises the eastern half of the Philadelphia SMSA, had a
total population of 952,000 in 1970. By 1980 it is expected that the population of the region will grow by over
20 percent. Its strategic location coupled with large quantities of flat undeveloped farm land and a rapidly
diminishing supply of developable land in other areas of the Philadelphia SMSA indicate that growth in this area will
be rapid in the next decade. Flood problems currently exist along many of the streams in Burlington and Camden
Counties. In addition, inadequate storm water drainage facilities cause considerable damage in the urban portions of
each county in the study area. Water quality problems are also prominent throughout the study area. The significant
water quality problems in the area result from sediment concentrations, discharges from municipal and industrial
facilities, natural inorganic contributions and agricultural pollution from fertilization and pesticidal applications.
Funds for FY 1975 will assist preliminary planning in identifying specific water resource needs, developing alternative
plans to meet these needs and evaluating impacts of selected alternative plans. Major emphasis will be placed on data
collection, formulation, flood damage surveys and a public participation process. A plan of study is being developed
in cooperation with concerned local, State and Federal interests and has tentatively identified present and future
water resources needs of the area.

The lower Delaware River and Delaware Bay Shore of New Jersey lies entirely in Cape May, Cumberland and Salem Counties. In general, it is a rural and sparsely populated region with intermittent pockets of development, and is located in a low lying tidal meadowland. The area is rapidly growing with summer homes and retirement communities. The primary problems of the area are severe and increasing erosion of shoreline and an increasing flooding problem from severe

storms. area.

These continuing problems are seriously jeopardizing the security of life and property and the economy of the Local interests desire corrective measures to provide beach erosion control, hurricane protection and related works along the lower Delaware River and Delaware Bay shore. These problems exist at almost all of the communities In an effort to develop the most comprehensive plan of improvement for beach erosion along the shoreline in question. control storm protection and other allied water resources purposes, the entire Delaware Bay Shore of New Jersey and the lower portion of the Delaware River in Salem, Cumberland, and Cape May Counties will be investigated in survey scope.

Jersey Meadows, N. J. & N. Y. (Linden) The meadows are located along rivers and coastlines in northeastern New Jersey. They border the following: Passaic and Elizabeth Rivers; Arthur Kill and Kill Van Kull. Total drainage area is about 2,400 square Hackensack, Tidal and river flooding occur frequently because of the low land elevations. A major drainage problem also miles. exists.

The purpose of the study is to formulate a comprehensive plan for balanced and coordinated development of the meadows and contigious areas. Scope includes: flood control; navigation; recreation; major drainage of the meadowlands; water pollution control and water supply. An interim report was prepared on the Elizabeth River. In February 1972 an interim report was initiated to cover flood control problems at Linden, N. J. Damages in Linden result from recurring flooding on the Peach Orchard and West Brooks which join Morses Creek to flow into Arthur Kill. With the funds requested for FY 1975 this interim report for Linden, N J. will be completed.
