- Spreadsheet model for quick costing.
PROJECT GOALS, ACHIEVEMENTS, AND BENEFITS
The Better Streets Plan outlines San Francisco’s vision for aesthetic, accessible and ecological streets. Programs involving landscaping, lighting, pedestrian furnishings, and pavement are all ways identified to achieve this goal. To implement this vision, San Francisco will need to prioritize and reorganize streetscape maintenance activities. McGovern McDonald Engineers led the development of operation and maintenance (O&M) life cycle costs for implementing stormwater best management practices on streets for the San Francisco Better Streets Plan. A spreadsheet model identifying staff time, materials, inspection frequency, maintenance frequency, etc. was developed for staff to easily and quickly estimate the site-specific costs of implementing stormwater and other Better Street elements. The Better Streets Life Cycle Model is one of three models that will be used as the basis for the Triple Bottom Line Tool and will be useful in conducting watershed assessments.
Development of a Low Impact Development (LID) Life Cycle Cost Benefit model that determines the costs and benefits of stormwater measures to both the customer and for the SFPUC.
Assessed the methylation potential and bioavailability of mercury discharged from point sources for the Water Environment Research Federation (WERF).
Provided a literature review to analyze graywater treatment alternatives for the SFPUC.
Identified stormwater and recycled water cost and benefits to the customer and SFPUC with implementation of LID techniques.
Development of stormwater best management practice O&M life cycle costs for street installation as part of the San Francisco Better Streets Plan.
Provided NPDES regulatory and permitting support for treated wastewater and stormwater discharges and Combined Sewer Overflows (CSOs) to the Bay and Pacific Ocean.
Development of nutrient management strategy for the Town of Plymouth, MA.
Development of a modeling tool for States and NPDES permit holders to assist nutrient management strategies for the Water Environment Research Federation.
Reviewed NPDES stormwater documents for transfer from private to SFPUC authority and recommended future monitoring program improvements for the SFPUC’s Mission Bay Development.
