EXHIBIT 1 TO ORDINANCE ATTACHMENT I SECOND AMENDMENT TO DEVELOPMENT AGREEMENT EVERETT RIVERFRONT REDEVELOPMENT (LANDFILL) FEIS MITIGATION REQUIRED Element of the Environment Action Mitigation is Where found in Resp.Party Implementation And tied to EIS Documents Time Frame Mitigation Measure Earth Resources G: Preloading can be used to mitigate settlement of the refuse Construction on DEIS 4.1.5 RC Building Permits materials at the landfill site and to mitigate settlement of soft native soils including Landfill/Tire Fire site peat,silt and organic silt. Earth Resources H: Pile foundations and stone columns may also be used in areas Construction of any DEIS 4.1.5,DEIS RC Building Permits of concern and where preloading may not alleviate settlement concerns. structures Appendix B Earth Resources I: A site-specific construction storm water plan shall be developed Any Construction DEIS 4.1.5 Responsible Grading and according to the EMC Chapter 14.28 Surface and Storm Drainage,and Washington Activity party doing the Building Permits State Department of Ecology(Ecology)requirements that can move soil work/project Earth Resources J: The construction storm water plan shall incorporate the Any Construction DEIS 4.1.5 Responsible Grading and following basic strategies and elements: a) Schedule/coordinate grading and Activity party doing the Building Permits construction activities to minimize soil exposure;b)Rapidly vegetate and/or mulch that can move soil work/project denuded areas; c) Keep runoff velocities low; d) Intercept and direct surface water to a stabilized discharge outlet; e) Prepare drainage and outlets to accommodate concentrated or increased runoff;f)Trap sediment on-site utilizing BMPs including: interceptor swales, straw bale barriers, silt fences, straw mulch among other methods;g)Inspect and maintain control measures frequently;h)Locate storm water retention and convenience systems down gradient from areas believed to have previous soil/groundwater contamination to prevent "soaking" of potentially hazardous or mobile soils; and i) Maintain and protect critical areas buffers. If possible,perform critical areas and buffer enhancements,if any are required,prior to upland construction to establish vegetation and stabilize slopes more completely. Earth Resources K: BMPs and erosion control measures will be specifically Any Construction DEIS 4.1.5 Responsible Grading and designed to address the individual causes and sources of erosion and sedimentation. Activity party doing the Building Permits The construction storm water plan shall include primary and secondary control that can move soil work/project measures to prevent over-reliance on a single design feature to control erosion and sedimentation. Monitoring and maintenance shall be conducted on a regular basis and after all large storm events by qualified personnel. Provisions for modifications to the erosion control system, based on monitoring and maintenance observations shall be included in the construction storm water plan. I-2
