groins with shore ends from about 6 to 11 feet above low water datum indicate 

 that these elevations are generally adequate to impound a low protective beach 

 where a supply of sand by littoral drift is available. Along the low marshy 

 shores of the study area, dikes or barrier beaches provide the only protection 

 to the landward areas from storm-wave action of Lake Erie. Protection against 

 wave action should extend to a height of 10 feet above low water datum to 

 assure prevention of damaging overtopping. For the remainder of the study 

 area where resistant bluffs exist alongshore, no further protection is needed. 

 Ice forms a protective coating over beaches during winter months, but the 

 lifting and battering action of shifting ice floes during the spring breakup 

 must be considered in designing shore structures for structural stability. 



The District and Division Engineers developed plans for protecting and 

 improving the shores of the study area as follows: 



a. Metzger Marsh - An earth levee along the north and east sides 

 of the State-owned property with top width about 10 feet at elevation 580.5 

 feet (10 feet above low water datum) and lakeward slope covered with a 3-foot 

 layer of riprap. 



b. Crane Creek State Park - Restoring a sand barrier beach along 

 17,800 feet of State-owned property by placement of sand fill to a 50-foot 

 berm width at elevation 579.5 feet (9 feet above low water datum) sloping 

 upward to elevation 580.5 feet at the parking lot, and construction of 36 

 groins (6 of which have already been built but require landward extensions), 

 spaced at 500-foot intervals and extending lakeward about 300 feet, to retain 

 the fill. 



c. State Highway Frontage Near Port Clinton - Providing a protec- 

 tive sand beach or a stone revetment. 



The District and Division Engineers considered the jetty proposed by the State 

 of Ohio at the navigation entrance to East Harbor. They concluded that it 

 should be built to an alternative alignment, that is, northeasterly rather 

 than easterly as proposed by the State, and extended farther lakeward (to the 

 4-foot depth contour) in order to better control entrapment of littoral drift 

 and protect the entrance from storm waves from the northwest quadrant. 



The District and Division Engineers found that restoration and protection 

 of the beach at Crane Creek State Park are justified by evaluated benefits, 

 and further found that the nature and amount of benefits warrant Federal par- 

 ticipation in the construction of considered improvements at Crane Creek State 

 Park. 



The Beach Erosion Board recommended that project be adopted by the United 

 Stated authorizing Federal participation by the contribution of Federal funds 

 in amount of one-third of the first costs of measures for the restoration and 

 protection of the shore at Crane Creek State Park, Ohio, substantially in
