10. Supplemental Documentation: All National Environmental Policy Act (NEPA) and related environmental coordination will be completed during the Feasibility phase. If no unexpected concerns or issues are raised during NEPA review, a Finding of No Significant Impact (FONSI) will be executed during this phase. The City of San Marcos intends to provide cash contributions ($0), LERRD's ($900,000) and provide work -in -kind services ($400,000) during project construction. In general, the City of San Marcos will provide work -in -kind that consists of: the riverbank widening measure (labor /equipment), sediment removal measure (labor /equipment), exotic terrestrial and aquatic vegetation removal measures (labor /equipment), sediment and vegetation disposal, in -stream aquatic plantings, riparian corridor plantings, and monitoring. Specific details associated with work -in -kind will be determined during the Feasibility phase of the project. Annual O &M will consist of sediment removal from the San Marcos River, associated tributaries and storm drainage retention pools; periodic dredging of wetlands; care of riparian corridor and grassland plantings; adjustments to water control structures; manual removal of invasive aquatic and terrestrial plant species; and maintenance of the SVT. Annual O &M costs are estimated at $59,000 and are the responsibility of the City of San Marcos. Traditionally, USACE ecosystem restoration projects have construction periods ranging from one to two years depending on restoration features being implemented. The City of San Marcos has requested an extension of the construction period to approximately five years. Several factors suggest that an extension in the construction period is warranted. First, due to the existing threatened and endangered species within the San Marcos River and environmentally sensitive nature of the area, the USFWS has requested that the sediment removal, invasive plant removal, and native aquatic planting processes be conducted slowly and with extreme care. Second, additional time will be required to assess and implement various adaptive management processes as the sediment removal, invasive plant removal, and native aquatic planting measures are implemented. Third, as part of the sponsor's work -in -kind, city personnel responsible for implementing these measures will require training to properly remove sediment and establish aquatic plantings. Fourth, the sponsor will be required to. continually remove sediment and invasive aquatic plant species and establish native aquatic plantings as part of their annual O &M requirements throughout the project life. Coordination with USACE Southwestern Division (SWID) indicated that a longer construction period maybe needed to insure the above stated restoration benefits. If the Prelimanry Restoration Plan is approved, documentation will be needed during the feasibility phase to support an extended construction schedule, along with supporting letters from key natural resource agencies supporting the need for an extended construction period. 17
