D. Cases alon the Calvert County and Lower Anne Arundel County shorelines This area contains the shoreline between the Patuxent River mouth and the Chesapeake Bay Rridge (Fiures 2.6 and 2.7). The sections below pres- ent a brief physical description of the shoreline and coastal processes, followed by a discussion of the case studies which were selected from this area. SHORELINE DESCRIPTIONS Calvert County The Calvert County shoreline along the Chesapeake Bay is composed mainly of large bluffs, hiher than 5O feet in many areas, which extend for several thousand feet at a stretch along the water's ede. The bluff faces are mostly exposed and eroding, hut they are covered with vines and shrubs in a few places. Sections of the bluffs are senarated by ravines and stream valleys which contain either woodlands or marsh. The beaches at the base of these bluffs are of varying widths and may contain small berms on the summer shoreline nrofiles. At Cove Point and near Long Beach, the beach is separated from the bluffs by a wide flat terrace which contains trees and open grassy areas. Most of the shorefront bluffs adjacent to the main Chesaneake Bay in Calvert County are heavily-wooded, with scattered residential develonment in among the trees. More concentrated residential development protected by shoreline structures can he found at the communities shown on the man. Houses in these areas are located both along the bluffs, and on the low berm that extends landward immediately adjacent to the beach. 2-48 WATER POLICIES FOR THE FUTURE Final Report to the President and to the Congress of the United States by the National Water Commission WASHINGTON, D.C.

Quincy Street Arlington, Virginia 22203 June 14, 1973 The President The Honorable The Honorable The White House The Speaker of the House The President of the of Representatives Senate Dear Mr. President: Dear Mr. Speaker:. Dear Mr. President: The firial report of the National Water Commission is presented herewith in accordance with the provisions of Public Law 90-515, approved September 26, 1968, which established the Commission. The report contains the Commission's conclusions and recommendations on the policies which it believes the Nation should adopt at this point in its history for the efficient, equitable, and environmentally responsible management of its water resources. The Commission has examined virtually the entire range of water resources problems facing the Nation, including the effects of water management on the Nation's economy and on its environment and how the differences between these two major objectives can be best resolved. The problems of reconciling Federal and State water law have been addressed, as have the problems of integrating ground water and surface water management. Each of the important purposes for which water is used has been studied, and appropriate policies have been drawn for improving both water-related programs and organizational arrangements. Ways in which existing water supplies can be used more efficiently and pres ent supplies can be augmented have also been examined. Standards by which interbasin transfers of water and other kinds of water projects should be judged have been developed and ways in which water management decisionmaking can be improved have been formulated. The report considers the problems of acquiring basic water data and pursuing research so that management of the Nation's water resources can be more knowledgeably and effectively based. Finally, the financing of future water programs as well as the important question of how and by whom the cost of water programs should be paid are also addressed. Accompanying the Commission's discussion and conclusions on these and other aspects of water resources are specific recommendations for action at the Federal, State, and local levels. Many of these recommendations would require enactment of new legislation. Some, however, could be accomplished by executive action alone or by action of State and local entities. The Commission has had the cooperation of and extensive review and comments from all levels of government, from private organizations, and from interested citizens. For this and for the broad range of public participation incident to the preparation of this report, the Commission is grateful. It is particularly appreciative of the cooperation of the Water Resources Council and its constituent agencies for their helpful review and comments. Finally, the Commission acknowledges with gratitude the valuable work of its staff; the research and analysis of universities, firms, public agencies, and individuals who worked for the Commission under contract; and the advice and guidance received from the experts who served the Commission as consultants. The Commission transmits its final report to you with the earnest hope that it will contribute importantly to the timely and wise solution of America's water resources problems.

The historical rate of erosion at the site was about 3 ft./yr. from 1845-1942. Revetment, on a 2:1 slope, consists of 30-300 lbs. stone in a 2 ft.-thick armor layer. A bedding layer of gravel 1 ft.-thick was placed below the armor layer. There was no filter material installed below the bedding layer. The revetment also has a concrete cap 1 ft. x 1.5 ft.-thick installed along the top. This structure is in generally fair to poor condition.

The historical rate of erosion at the site was 1.5 ft./yr. from 1847-1970. Structure consists of timber bulkhead which is angular in planform. To the south alongshore, the neighboring property has installed several 8 ft.-long concrete pipes laid out perpendicular from the shoreline to act as groins. To the north alongshore., 3 concrete rubble groins are present. The bulkhead is in generally good condition. The rubble groins are extremely effective in trapping littoral sediments, and pocket beaches are present between the groins. The concrete pipe groins have trapped some sediments to form a smaller beach, but these structures are not sand-tight. 2-74 scarce resources.

Cases along the Upper Eastern Shore of Chesapeake Bay This area of the northern Chesapeake Bay shoreline (Figure 2.10) contains portions of Cecil County and Kent County. The sections below present a brief physical description of the shoreline and coastal processes, followed by a discussion of the case studies which were selected from this area. SHORELINE DESCRIPTIONS Eastern Cecil County The Cecil County shoreline along the Elk River is composed of rollinq hills up to 80 feet in height. At most spots, the land slopes gently down to the water, but some hillsides end in exposed vertical walls of erodinq sediments. The beaches in this area are of varying width, and contain some gravel. Enough sand is present in some areas of the shoreline system to form wide sandy berms on the summer beach profiles. Marshes are found in protected coves, and in the headwaters of the Flk River. Most shorefront areas on the western side of the Elk River contain farmlands or woodlands. Houses are located in among the trees on hillsides next to the shore, on low hanks Drotected by erosion-control structures, or in open grassy areas behind a wide vegetated buffer zone. On the eastern side of the Elk River, the terrain is generally flatter, and shorefront areas contain banks ranging from 5 to 15 feet in height. Areas near the entrance to the C&D Canal contain concentrated residential shorefront development and networks of erosion-control 2-100 fishery.

Cases along Kent Island and Talbot County Shorelines This area of the northern Chesapeake Bay (Figures 2.12 and 2.13) contains portions of the shoreline in Queen Anne's and Talbot Counties. The sections below present a brief physical description of the shorelines and coastal processes, followed by a discussion of the case studies which were selected from this area. Kent Island] The Queen Anne's County shoreline on Kent Island contains farmland, a few heavily wooded areas, and many clusters of shorefront homes protected by erosion-control structures. North of the Bay Bridge, the Kent Island shoreline is composed of low rolling hills which usuallv end at the water's edge in exposed hanks from 3 to 15 feet in height. An exception is at Love Point, where the high around slones gently down to the water's edge. Shorefront areas on this reach contain mostly farmland, and the few houses that are present are separated from the water by a wide vegetated buffer strip. Below the Bay Bridge, many of the shoreline banks support residential development, and shorefront areas are often landscaped, covered with lawn grass and shrubbery, and protected hv erosion-control structures. Clusters of homes are interspersed with tidal creeks surrounded by marsh. Farther south, the shoreline contains farmlands and woodlands at the edges of eroding hanks, and the beach is nearly uninterrunted by erosion-control structures.

The historical rate of erosion at the site was 8 ft./yr. from 1847-1942. The timber bulkheads replaced sheetpile bulkheads at this site. Stone revet- ment was installed along with filter cloth. These structures are in generally good condition. The offshore profile is very deep at the base of the seawall, and no beach existed at the time of the site visit in summer of 1980. There is evidence of wave overtopping at locations along the timber bulkheads. 9 COPPER CAP WALE -6 BATTEN BOARD GRADE OF FILL, LEVEL AT + 4.0 8"x 8" WALES, BOLTED TO 20x7/8 GALV TIE ROD, W/ GALV.OGEE NUTS ACH EN -3 ASHERS a AT EACH EN PILE W/ 7/8" GALV.

The original timber bulkhead and one groin were constructed in 1973 at a cost of $63.29/ft. and $35.80/ft., respectively. In 1976, 493 ft. of timber bulkhead and two stone groins were added at a cost of $79.35/ft. and $54.91/ft., respectively, and the two existing groins were refurbished and extended at a cost of $39.92/ft. Timber bulkheads consist of tongue-in-groove sheeting. and piles are spaced on 7.5 ft. centers. Groins were constructed of 400-800 lbs. stone on a 1.5:1 slope with a 3 ft.-wide crest. These structures are in generally good condition. No beach sand was observed at the site in thesummer of 1980. There is strong wave activity in this area, and the wave crests were observed to reflect against the vertical bulkhead. Bulkheads to the north alongshore are being forced landward by waves, and backfill is being lost through the bulkhead wall. There is also evidence of wave overtopping and splashover at this site. 10- 8 6 4 2 0 TREATED CAPBOARD COPPER CAP TOP OF WHALE 6"X6" WALES BOLTED TO PILE WITH 3/4" GALV. BOLTS A 3"X1/4 GALV.

In all other cases water The danger of setting the restoration of natural quality different from that which would exist in water quality as a national goal lies not merely in its nature will adequately support the desired uses. In conceptual unsoundness, but in its potential for doing fact, natural water itself often is unfit to satisfy long-term harm to the pollution control effort. Like important uses, and a requirement that all water other oversimplified solutions to complex social discharged after use be distilled would not assure problems, this policy holds out a promise of water of useful quality.
