    SHORELINE ALTERATIONS IN HOOD CANAL AND THE EASTERN STRAIT OF JUAN DE FUCA Point No Point Treaty Council Technical Report 03-1 Copies of this report may be downloaded at the Point No Point Treaty Council website: www.pnptc.org PNPTC Technical Report 03-1 Shoreline Alterations in Hood Canal and the Eastern Strait of Juan de Fuca Prepared by Ron Hirschi, Consultant Ted Labbe, Port Gamble S’Klallam Tribe Alan Carter-Mortimer, Point No Point Treaty Council March 2003 Point No Point Treaty Council 7999 N.E. Salish Lane Kingston, Washington 98346 Project funded by Bureau of Indian Affairs “Watershed Restoration Program” Contract No. GTP00X90310 SUMMARY This report describes the results of an inventory of marine shoreline development throughout Hood Canal and the eastern Strait of Juan de Fuca. It also interprets the results on a large scale and for selected smaller areas. Shoreline features were field mapped by boat employing a Global Positioning System to mark positions. Information collected included shoreline features as points (e.g. docks, jetties, launch ramps, etc.) and as lines (bulkheads and backshore landforms) along the shoreline. Data summaries were generated by attaching point and line features to shoreline Geographic Information System layers and grouping these results by drift cells within sub-regions that were, in turn, grouped within larger regions. A total of 595 km of shoreline was mapped, extending from the Union River near Belfair in Lower Hood Canal to Dungeness Spit near Sequim in eastern Strait of Juan de Fuca. Bulkheads were found to cover approximately 18 % of the total mapped shoreline.

  • Daniel Aquilante and Kathy Aquilante
    STATE OF NEW YORK DEPARTMENT OF ENVIRONMENTAL CONSERVATION ________________________________________________________________________ In the Matter of the Alleged Violation of Article 25 of the Environmental Conservation Law (AECL@) of the State of New York and Title 6 of the Official Compilation of Codes, Rules and Regulations (A6 NYCRR@) of the State of New York, Part 661, RULING Case No. R2-20070213-73 by DANIEL AQUILANTE & KATHY AQUILANTE, Respondents. ________________________________________________________________________ PROCEEDINGS Department staff brought this enforcement matter in 2008 alleging that respondents violated the tidal wetlands regulations by constructing an addition to property they own at 60 West 17th Road, Broad Channel, New York (site) without a tidal wetlands permit. Department staff alleges that the site is located in a tidal wetlands adjacent area and the applicable regulations require a permit for such activity. Department staff previously moved for an order without hearing in 2008 and the motion was denied as a question of fact remained (see Letter Ruling, Dec. 17, 2010). The matter was adjourned in January 2011 while the parties attempted a mediated settlement. Those discussions failed to reach a resolution of the matter. Respondents now move to dismiss the proceeding alleging that because the site is not located in a tidal wetland or its adjacent area, the Department does not have jurisdiction over the site. Department staff opposes that motion and again moves for an order without hearing. Respondents served the motion to dismiss the alleged tidal wetlands regulations violations on the Department on or about March 31, 2011. Respondents support their motion with a memorandum of law and an affidavit of respondent Daniel Aquilante.

  • Detailed Report. New Construction Work Paid for out of Corporate Stock
    PART 11. DETAILED REPORT. NEW CONSTRUCTION WORK PAID FOR OUT OF CORPORATE STOCK. Shore Road. The contract for the completion of the sea wall along the Shore Road, between Latting Place and Bay Ridge Avenue, and between 92d Street and Fort Hamilton Avenue, which was begun in 1914, was practically completed during 1915. The work consisted of constructing 6,624 linear feet of granite ashlar and concrete sea wall, furnishing and placing 46,000 tons of rip-rap and 350,000 cubic yards of earth fill. The contract for the furnishing and deposit- ing of 250,000 cubic yards of earth fill along the Shore Road, between 94th Street and Fort Hamilton Avenue, was begun during June, 1915. The work of filling in has been more than 50 per cent. completed this year. Dreamland Park. The contract for the construction of seven timber groynes along the beach front of Dreamland Park was completed during May, 1915. The cost of the work was $11,688.60. The purpose has been to stop the washing away of the beach. Records show that since 1874 more than 30 acres of public beach at Coney Island has been lost in this way. At one point, near the foot of the Ocean Boulevard, the Shore line has receded 1,100 feet. Since these groynes have been completed they have protected the beach from erosion and have also reclaimed considerable beach lands. In the spring they will be built up further and more land reclaimed. The contract for the removal of the old timber steamboat pier in front of Dreamland Park was begun during May, 1915.

  • Coastal Management Element
    COASTAL MANAGEMENT ELEMENT DATA INVENTORY AND ANALYSIS PURPOSE The purpose of the Coastal Management Element is to protect human life and to limit public expenditures in areas that are subject to destruction by natural disaster. It is also to plan for, and where appropriate, restrict development activities where such activities would damage or destroy coastal resources. COASTAL PLANNING AREA Surfside is an Atlantic Ocean coastal community located on a barrier island along the southeast coast of the Florida peninsula in Miami-Dade County. The barrier island the Town is located on is separated from the mainland by the north end of the Biscayne Bay estuary. The Hurricane Storm Surge Evacuation Map prepared by the Miami-Dade County Office of Emergency Management has identified the Town and the entire barrier island as hurricane vulnerable, and classified the entire barrier island as a Zone B evacuation area. Zone B is at greatest risk for storm surge for Category 2 and higher storms., The entirety of the Town is recognized as the Coastal Planning Area (CPA). LAND USE IN THE COASTAL PLANNING AREA The existing land uses in the Town are identified on Map FLU 1 Existing Land Use. The Future Land Uses within the Town are identified on Map FLU 7 Future Land Use. The Future Land Use Element inventories and provides greater detail on these uses. The Town has no identified blighted areas in need of redevelopment, and has no Community Redevelopment Agency. NATURAL RESOURCES IN THE COASTAL AREA The natural conditions of this barrier island have been highly altered. The Town is nearly built out with only a few vacant lots.
