Oxford Retention Basin Multiuse Enhancement (Water Resources)
Summary
The Project will mitigate localized flooding, address water quality deficiencies, enhance native habitat, improve site aesthetics, and provide passive recreation features. The proposed improvements will  reassure the community of any future flooding along Washington Boulevard and Oxford Avenue. The project will significantly revitalize the area around the retention basin by providing public access with the addition of walking paths, observation decks, and shorter ornamental fencing for public safety.
EnvISIon Quality of Life
The proposed project scored relatively high in the Quality of Life category. The surrounding community will benefit greatly with the proposed project. The restoration of the basin ecology and water quality will enhance the aesthetics of the site. Allowing public access with the construction of walking paths and observation decks will improve site accessibility and passive recreation for the community. Educational signage of the basin functions and restored native habitat will further enhance community linkage with the project site.
EnvISIon Leadership
DPW provided superior leadership and stewardship for the project's progress. Community and stakeholder outreach and input resulted in the scope modification of the original project.  Meetings with the community, stakeholders, and affected agencies provided DPW with goals to enhance the project with the public interest in mind. Public access to the site and the restoration of native habitat were successful byproducts of their input. The Oxford Basin Enhancement Project is one of several projects within the Marina Del Rey master plan for improvements in the area. Extensive coordination and collaboration between the Project Engineers and Managers was accomplished to manage these  improvement projects in order to achieve optimal and consistent workflow free of redundancies.
EnvISIon Resources Allocation
The score for Resource Allocation category was low mainly due to DPW policy and standard practices for design. For example, DPW standard contract specifications do not specify for Contractors to use regional materials, recycle their byproducts, or use products from manufacturers' that support sustainable practices. However, the Project Engineer may consider these in the Special Provisions for the project. DPW do not commission or monitor energy systems nor perform net embodied energy study as these may be cost prohibitive.
EnvISIon Natural World
The project scored highest in this category mainly because the project involves the restoration of a native habitat and water body within the site. In addition, the flood protection function and water quality will be enhanced with the removal of contaminated sediment from the basin. The reprogramming of the tide gates operation will provide an efficient management of stormwater runoff and tidal fluctuations of surface water from the marina. Increase water circulation promotes improve water quality and provides a healthier habitat for avian species and native plants.
EnvISIon Climate and Risk
The project scored relatively low for the Climate and Risk category. Comprehensive life cycle carbon analysis and climate impact assessment plan are not typical in DPW's infrastructure projects. These tasks may be considered, but are probably cost prohibitive and provide no significant changes to the project. The basin improvements include the restoration of flood protection to a 50-year storm event. The increase of basin capacity addresses and mitigates local area flooding issues. The tidal gates can also be used to isolate the basin from the harbor in case of manmade hazards such as spills.
