CMI HomehuiNer's Inc. Welland Oelinealion and installation, irrigation should be at a rata of 1/2" of water twice a week. During the second year after installation, irrigation should be at a rate of 1/2" of water once a week. However, if more than 10% of plant replacement occurs, watering rates should be maintained at a rate of 1/2" of water twice a week for the duration oF the monitoring period. To minimize the potential for plant desiccation in the mitigation areas, a soil moisture retention agent will be incorporated into the backfill of planting pits, as required, based on site conditions. 8.0 CONSTRUCTION MANAGEMENT Frior to commencement of any work on the site, the clearing and construction limits will be staked and a silt fence will be installed along these limits. Significant habitat features and vegetation to be retained or relocated will be clearly marked in the field. A pre-construction meeting will be held at the construction site to review and discuss all aspects of the mitigation project with the selected contractor, the owner, and the wetland consultant. A wetland biologist will regularly supervise plan implementation during construction to ensure that the objectives and sF�eci!iations of the mitigation plan are met. Any significant modifications to the design that may occur as a resuit of unforeseen circumstances will be approved by ihe owner, the City, and Talasaea Consultants prior to their implementation. Stormwater containment and City of Everett Best Management Practices (BMPs) wiil be implemented during construction to protect the water quality of the wetland from possible impacts. Implementing BMPs wili act to minimize erosion and sedimentation and protect water quality within the wetland during storm events. Silt fences, straw bales, and other structures wili be installed to slow runoff and remove suspended sediments during construction. BMPs to be implemented may include, but will not be fimited io: i. site runoff containment, ii. street sweeping, iii. filter fabric fences, iv. interceptor sweles, v. rock-lined swales, vi. catch basin inserts, vii. straw bales and rock and check dams, viii. rocked road entries, ix. construction practices, x. covered stockpiles Street sweeping will clean construction sediments from roads to minimize sediment-laden runoff into storm drains. Filter fabric fencing at the clearing limits will reduce over-ground stormwater sediment transport. Interceptor swales will divert construction runoff from sensitive areas to treatment facilities. Rock-lined swales will reduce the sediment loads in stormwater runoff. Catch basin inserts will act as sediment control during construction by removing sediment, oil and grease, and other pollutants adsorbed to sediments from stormwater. Straw bales placed in ditches will slow water down and catch sediment as stormwater �aaves the construction site. Rocked road entries will minimize mud and sec�iment col'�ction on roadways. Construction practices will include capping, covering, and stabilizing exposed soil before building. Other Bh1Ps will be implemented, as appropriate. 20 May 2003 Talasaea Consultanls, LLC 364C-NitRpt4(20May03).doc Page7 ,��
