Exhibit 1 13 Habitat gained from restoration: 6.0 IVA acre-points. (5) Mechanisms to insure implementation and to measure effectiveness: The project will be a condition of permits issued for the rail/barge transfer facility by the US Army Corps and WDFW. The Project includes a 20-year monitoring and adaptive management program that addresses vegetation, fish, wildlife, benthic invertebrates, beach stability, and requirements for renourishing to offset sediment losses from the restored beach. b. Public lands between the Mukilteo Tank Farm Property and the Port of Everett's South Terminal (EMU 7) - Culvert Replacement (1) Project Description: At least nine streams discharge to Port Gardner Bay through culverts under the BNSF railroad in this area. These streams include Edgewater Creek, Powder Mill Gulch Creek, Narbeck Creek, Merrill and Ring Creek, Phillips Creek, Glenwood Creek, Seahurst/Glenhaven Creek, Pigeon Creek No. 2, and Pigeon Creek No. 1. Potential restoration opportunities include replacing the existing culverts under the BNSF railroad that limit transport of sediment and woody debris from these small coastal streams to the beach. In some cases, these culverts also restrict access by anadromous salmonids to those streams. Culvert replacement would be in the form of either a bridge, or a larger, less restrictive culvert designed to allow both upstream and downstream passage of salmonids as well as free delivery of stream-born sediments and wood to the nearshore. (2) Schedule: No culvert replacement is currently scheduled. It is most likely that this activity would occur in conjunction with a large scale public project. (3) Costs/Funding Sources: Cost of culvert replacement is unknown but expected to be high. A primary factor in construction costs is the affect it could have on operating the BNSF rail line during certain portions of the work. Culvert replacement in this area has been deemed to provide only minimal habitat benefits for the cost incurred; however, in certain circumstances this action may make sense. Prospective Funding Sources: Grants and development mitigation are possibilities for funding sources. The ability to implement this project and the actual timing of any restoration is contingent on a significant public works project, securing funding for this restoration and feasibility challenges. (4) Habitat Function Benchmark Gain: A culvert replacement would theoretically improve access by anadromous fish to one of the small freshwater streams entering the sound along this beach reach.
