South Permits Branch 198302025 (IP-TA) Modification Harbour Ridge Property 12600 Northwest Harbour Palm City, FL 34990 Dear Gentlemen: Owner's Association, Inc. Ridge Boulevar(l' Reference is made to your joint permit application received April 10, 2000, in which you asked to modify Department of the Army Permit Number 198302025 issued on November 6, 1985, reissued on ll..April, 1996, and due to expirz__=:.1.1..April 2001. By letter dated 20 October 2000, submitted by Croach Engineering, you also requested a five-year permit extension for completing the riprap breakwater. The original permit authorized the construction of two multi- family docks with a total of 117 boat slips. Subsequent modifications and permit reissuance authorized minor revisions to docks 1, 2, and 3 including 118 boat sli,.p.s and the installation of 5,190 linear feet of riprap breakwat,er". This modification includes further revision of docks 1, 2 and 3 resulting iri a net reduction of 10 boat slips and an additional five years to complete the riprap breakwater. The purpose of the dock revisions is to increase mooring space for larger vessels up to 60 feet in length. The time extension is needed due to the severity of erosion and limited funds available. The impacts of.the proposed work.on navigation and the environment have been evaluated and found to be insignificant. No additional impacts to resources, water quality, submerged aquatic vegetation, or manatees will result from this modification. The permit is hereby modified in accordance with your request and will expire on 11 April 2006. You should attach this letter and the enclosed revised project plans to the permit. All conditions of the previous permits and permit modifications, including the attached manatee precautions remain in effect. Thank you for your cooperation with our permit program. If you have questions please contact Ms. Tori Agramonte at the WM letterhead address, by telephone at 561-781-8085, or fax at 561-781-8106. BY AUTHORITY OF THE SECRETARY OF THE ARMY: �. Jame G .

This letter represents the Service's view on the effects of the proposed action, in accordance with section 7 of the Endangered Species Act of 1973 (16 U.S.C., as amended, 1531 et seq.)(ESA) and the provisions of the Fish and Wildlife Coordination Act of 1958 (48 Stat. 401, as amended; 16 U.S.C. 661 et seq.). PROJECT DESCRIPTION The Army Corps of Engineers (Corps) proposes to modify a permit for an existing marina. The modification includes a reduction iti total boat slips from 118 to 108 slips. The purpose of the project is to increase mooring space for larger boats up to 60 feet in length. The project is located in the North Fork St. Lucia River, section 26, Township 37S, Range 40E, St. Lucie County, Florida. THREATENED AND ENDANCrERED SPECIES BY letter dated October 16, 2000, the consultant for the applicaftt informed us that the existing facility is fully occupied seasonally and that reducing the number of boat slips to increase mooring space for larger boats will result in a reduction of boats at the facility. According to the Public Notice, the standard precautions for the protection of the West Indian manatee (Trieheehus manatus) will be incorporated as special conditions of the permit. Thus, the Corps has determined that the project "may affect, but is not likely to adversely effect" the manatee. Based on the Corps inclusiort of the standard manatee protection measures as special conditioDs of the Department of the Army permit issued for this project, the Service concurs with this • determination, There is no designated critical habitat for this species in the vicinity of the project. site, therefore, none shall be affected. This written concurrence letter fulfills the consultation requirements of section 7 of the ESA, and no further action is required. If modifications are made in the project, if additional information involving potential effects to listed species becomes available, if a new species is listed, or if designated critical habitat may be adversely affected by the project, reinitiation of consultation may be necessary. FISH AND WILDLIFE RESOURCES A.ceotding to your letter, the lagoon bottom at the site is unvegetated. Therefore, the Service does not object to the issuance of the Department of the Army permit for the proposed action. Thank you for your cooperation in the effort to protect fish and wildlife resources. If you have any questions regarding this project, please contact Chuck Sultztrm at (561) 562-3909, extension 241.
