Document Description
The proposed project involves a phased restoration of the Loma Alta Slough's wetland and upland habitat across seven lots, totaling approximately 5.8 acres. Habitat restoration activities would include dredging and removal of fill to expand the wetland, marsh plain grading and channelization, restoration planting and long-term biological monitoring. Removal of disturbed infill would expand the extent of the Slough to increase habitat function and size, improve water quality and provide new public recreational opportunity. A new 1,050 ft. long pedestrian nature trail would traverse the northern project boundary. In Phase 1 of the project, habitat restoration and trail construction work would occur across six City-owned parcels (APNs 153030290, 1530304800, 1530304900, 1530304100, 1530304200, 1530110600) and within a portion of the NCTD right-of-way. Phase 2 of the project includes additional habitat restoration and trail construction at an additional 1-acre lot proposed for acquisition by the City of Oceanside (APN 1530304300). The project would require a zone amendment and general plan amendment.
