Contract# IRL2022-07 <br />Encumbrance# GLO1-I895/GLO1-2205 <br />V. SCOPE OF WORK (Outputs/Deliverables): <br />A. Mechanical Treatment of Non-native Vegetation: <br />As part of the IRLC Grant process, the County retained a contractor to cut survey lines throughout <br />all three islands to expedite the collection of topographic data. These survey lines traversed the <br />islands from north to south, and east to west. The lines varied in width from 12 feet to over twenty <br />feet. Equipment was barged to the islands as part of this work. <br />The contractor used for this mowing has been retained to complete the Phase I work on Duck <br />Head Island. The proposed cost for the mechanical clearing of Duck Head Island was used as an <br />estimate for completing similar work for Phase 4 of the Earman restoration project. The Duck <br />Head mowing was completed in May 2022. The machinery was barged to Earman Island in early <br />June 2022, and mowing has been initiated. The equipment used is able to do broadcast clearing, as <br />well as precision clearing in, and around, native trees and vegetation. Once complete, the area will <br />have a layer of mulch (ground to a level suitable for planting, as applicable) that will help keep <br />moisture around the base of installed plant materials. The proposed schedule for this work is <br />presented in Section VII. <br />B. Site Maintenance: <br />As shown on the proposed project schedule, there will be a period between when the mechanical <br />clearing is completed and planting is initiated. During these months, County staff will complete <br />monthly inspections to treat re -growth of opportunistic non-native vegetation. This treatment <br />period will reduce the effort required for follow-up treatments once these areas are re -vegetated <br />with native plants. <br />C. Procurement of Plant Materials: <br />The proposed planting scheme is depicted in Section II, and shows the approximate location of the <br />areas to be planted, as well as tables outlining the species, sizes, and quantities of materials to be <br />installed. The County plans to initiate the procurement of the plant material in early 2023 to allow <br />for the selected contractor to procure the required plant materials and prepare for installation.
