Scope of Work <br />continued <br />City of Everett 13 <br />Dorn Ave. Drainage Improvements Otak <br />and determine buffer widths per Everet Municipal Code (EMC) 19.37 (Critical Areas). The OHW line on <br />any streams in the survey area will be delineated in accordance with USACE Regulatory Guidance Letter <br />05-05 (Ordinary High Water Mark Identification) and Determining the Ordinary High Water Mark for <br />Shoreline Management Act Compliance in Washington State (Ecology 2016). <br />Otak will prepare a Wetland and Stream Delineation Report in accordance with state and federal <br />standards, including special flood hazard areas, wetlands, streams, and fish and wildlife habitat <br />conservation areas (FWHCAs). <br /> <br />10.2 Alternatives Analysis and Develop Permitting Strategy <br />Design alternatives and permitting requirements will be evaluated to help support selecting a preferred <br />alternative for each of the utility outfalls, including estimated permit application review timelines for <br />comparing the alternatives to the project schedule. A permit matrix for comparing the different alternatives <br />will be prepared. <br /> <br />The projects are anticipated to be exempt from critical areas regulations per Everett Municipal Code <br />(EMC) 19.37.050.A(f) as long as the outfall replacements do not expand or encroach further into critical <br />areas (e.g., North Creek, riparian buffer, or wetlands). If designs are not consistent with the exemption <br />criteria then a critical areas permit will be required. <br /> <br />10.3 Prepare JARPA (Contingency) <br />The projects area potentially exempt from Clean Water Act (CWA) permitting requirements if they qualify <br />for the maintenance exemption. To qualify for the maintenance exemption, the maintenance action must <br />not modify the character (e.g., fill material), scope, or size of the original fill design. If the projects include <br />discharging new material in North Creek or associated wetlands then a federal permit and/or state <br />permits will be required. <br />A Joint Aquatic Resources Permit Application (JARPA) will be prepared at the 60 percent design stage. <br />The JARPA will be used to apply for the Ecology Section 401 certification; Washington State Department <br />of Fish and Wildlife (WDFW) Hydraulic Project Approval (HPA) if necessary; and a Department of the <br />Army (Section 404) permit from the Corps of Engineers. The project is anticipated to be permitted under a <br />Nationwide Permit #3 (Maintenance) or #58 for Utility Lines and not result in the conversion of wetland <br />habitat. Otak will submit the pre-filing request to Ecology for the Section 401 certification. An impacts <br />assessment and restoration plan for permanent and temporary impacts will be completed under this task. <br />Otak will prepare the JARPA figures for the project design to include with the City’s permit applications for <br />Corps, WDFW, and Ecology permitting. Otak will prepare the figures in accordance with current JARPA <br />standards, which allow 11”x17” drawings. Otak will calculate quantities and areas of impacts <br />(waterbodies, buffers, etc.) for permitting. The 60% design construction drawings will be used to prepare <br />permit applications. <br />Cultural resources review is not expected to be required by the USACE for this project, and is not <br />included in this scope of work. All temporary impacts to sensitive area vegetation will be restored in kind. <br />A restoration plan will be prepared for the JARPA application. <br />10.4 Prepare ESA Compliance (Contingency)
