○ Secondary slab-on-grade (flatwork) recommendations ○ Pavement recommendations for hot mix asphalt ○ Geotechnical recommendations associated with stormwater treatment ● The geotechnical report will include a summary of the existing conditions and proposed improvements, surface and subsurface conditions, groundwater observations, seismicity, laboratory test data, boring log data, and a site plan showing exploratory locatio ns and improvement limits. Task 2.6 – Bathymetric Survey ● Mobilization and Calibration ○ Coordination with Project Managers, field plan and HASP generation and the programming of the sonar acquisition computers and getting the vessel and crew to the site. ● Condition Multibeam Bathymetric Survey ○ Collect near 100% bottom coverage throughout the survey footprint. ○ The survey footprint includes the marina basin, and the southern, western and northern outside shorelines. ● Collect Topographic Data ○ The Bathymetric Survey Team will also collect LiDAR-based topographic data in order to supplement the bathymetric data collection effort. This will ensure a seamless surface between the bathymetry at the toe of the surrounding levee up to the top of levee bank (above MHHW). ○ Existing culverts will also be identified and surveyed. ● Raw Data Reduction, Charting and Reporting ○ Raw sonar data will be reduced to bathymetric elevations (Ft. MLLW) and the following deliverables will be submitted: ○ Plan view drawing showing contours at 1-foot intervals (in PDF and AutoCAD format) ○ Survey Report: detailed report of survey outlining equipment, calibration procedures and results amongst other important metadata. ● All elevations will be represented using NAVD88 datum. Task 2.7 – Arborist Report ● Site visit to inspect, inventory, and tag all trees on site that are greater than 6 inches DBH and along the project site’s immediate perimeter ● For each tree, data on species, tree health, DBH, and canopy (dripline) will be collected ● Following completion of the site visit, Consultant will prepare an Arborist Report, including individual tree evaluation, tree location, numbering plan, protected trees, and trees which may be suitable for transplant within the project limits. Task 2.8 - Biological Resources Technical Memorandum ● Reconnaissance-level site visit of the project area. The site visit will be conducted during low tide when subtidal communities are exposed to allow biologists to assess whether sensitive habitats, such as eelgrass beds or native Olympia oyster colonies are present and need to be considered further. ● Search relevant databases to determine which protected species and/or critical habitat have potential to occur in the vicinity of the project; these databases will include the California Department of Fish and Wildlife (CDFW) Natural Diversity Database, the California Native Plant Society database, and the U.S. Fish and Wildlife Service county list.
