1.0 EXECUTIVE SUMMARY The University of California, San Francisco’s Campus Water Action Plan (WAP) is the blueprint for reaching a per capita 20% reduction in water consumption by 2020. The WAP fulfills the University of California Office of the President’s Sustainability Practices Policy requirement, Chapter V. Procedures, Section I. Sustainable Water Systems, Subsections 6 – 9.2 The WAP outlines the path to achieving UCSF’s contribution to UCOP President Janet Napolitano’s goal to reduce per capita water use by 20% throughout the UC system by 2020.3 The WAP is designed for flexibility and will evolve as the Campus physical environment changes, as the population grows, as demand on water resources changes, as new technologies become available, and as staff develops a better understanding of the water delivery infrastructure and consumption trends through both ongoing submetering and auditing programs. The University has made substantial progress towards reaching its goals having reduced per capita consumption 4.4% by the end of FY12-13. Initial projects that contributed to this reduction include the recycling of condensed steam and recycling excess filtered water from laboratories that previously went down the drain. Additional projects that the University is implementing include replacing older and wasteful restroom fixtures with high and ultra-high efficiency fixtures, retrofitting or replacing water consuming equipment such as walk-in boxes, sterilizers, and autoclaves, eliminating once-through cooling devices, strengthening the PM program, reducing continuous flow and addressing leaks. As the University continues to collect more water consumption data, staff will make informed choices about what projects to implement investing in projects that will strengthen our water management program and reduce overall consumption. There are many challenges to meeting the 20% target by 2020. Some of these have yet to be realized. However, through the collaborative efforts of University departments, organizations, and an engaged staff, we expect to do our share in contributing to the UCOP’s system-wide reduction goal. 2.0 CAMPUS-WIDE CONSUMPTION DATA AND CONSUMPTION REDUCTION TARGETS

UCSF Staff is using FY2007-08, FY2008-09, and FY2009-10 (FY2007-10) as the benchmark period for determining target reductions. The average

consumption during the benchmark period was 226,024,656 gallons with a weighted campus user (WCU)4 of 15,161.96 gallons. Since the benchmark period, UCSF has achieved a 4.4% reduction in per-capita water consumption through FY2012-13 (ending June 30, 2013). In FY2012-13, the WCU average consumption was 14,494.83 gallons. To achieve the 20% per capita reduction target, UCSF’s WCU average consumption will need to drop to 12,129.57 gallons by the year 2020. Table 2.0 provides the actual consumption totals and WCU average for FY2007-10 (benchmark period) and FY2012-13. For each fiscal year beyond FY2012-13, Table 2.0 shows the targeted WCU average consumption rate and the corresponding incremental reduction shown in percentages until

we reach FY2019-20 when we achieve the WCU consumption goal of 12,129.57 gallons. The projected consumption levels are extracted from

UCSF’s 2014 Long Range Development Plan, Water Supply Assessment Data, rev: January 1, 2014. As noted in Table 2.0, the total projected consumption for FY2019-20 with reduction strategies in place represents an overall decrease of 5,707,988 gallons from the benchmark period. We expect to reach this goal even as the campus population is expected to increase by approximately 8%. An asterisk (*) in the following matrices indicates that definitive data is unavailable at the time of writing but will be included when it becomes available.

Chart 2.0. In 2011-2012, UCSF CLS Facilities Services (Facilities) and an independent contractor performed an audit of water consuming devices, equipment and fixtures on the Parnassus Campus and summarized the estimated water use breakdown in Chart 1.0. With this data, Facilities addressed the largest users of potable water supply and replaced less efficient toilets and urinals with ultra- and high-efficiency fixtures. In 2013, Facilities used the same independent contractor to perform a similar audit at its other sites and buildings to help guide water conservation strategies. Facilities staff continues to perform detailed audits on an ongoing basis working with end-users to develop and implement best practices, retrofit equipment, devices and fixtures, and update the WAP benchmark.

CHART 2.0: PARNASSUS HEIGHTS CAMPUS ESTIMATED WATER USE BREAKDOWN

Chart 2.1 represents the breakdown of total water consumption at each UCSF Campus site for FY12-13. More than half of all water is consumed at the Parnassus Heights Campus. However, the Parnassus Heights Campus daily population represents almost 80% of the total daily population for UCSF. This information demonstrates the need to focus the next phase of our submetering and additional auditing programs at the Mission Bay Campus in order to develop tailored strategies to reduce consumption at this campus.

The San Francisco Public Utilities Commission provides UCSF’s potable water. Refer to ADDENDUM 5: WATER SOURCE. UCSF uses potable water for all major water consuming classifications with the exception of the Parnassus Central Utility Plant that uses RO Reject for its cooling tower makeup. At the other three campuses where the University has cooling towers, we use potable water for makeup. Table 3.0 breaks down the major water consuming classifications. As the University continues to implement our wireless submetering program, we expect to have a better understanding of the consumption amounts for each of these classifications allowing us to set specific reduction goals.

6.0 CONCLUSION

UCSF’s Commitment to Its Mission and Water Reduction

UCSF has built an international reputation on the contributions it has made to health sciences teaching and research and for advancing health

worldwide. It accepts its responsibilities as a member of the University of California system, recognizes the important role it plays in the local

community and Bay Area, and is proactively involved in addressing the issues that challenge the state of California. Following the model of

collaboration, research, innovation, and implementation that drives its four professional schools and graduate programs, UCSF continues to make

important gains in its efforts to reduce water consumption and develop a strong water management program to meet the challenges of an

uncertain future. As staff continues to implement water reduction projects, the University is learning a lot about our water infrastructure and

campus consumption trends. We are able to incorporate this knowledge on an ongoing basis into the Water Action Plan so that it serves the needs

of our customers while meeting the UCOP’s 20% reduction goal.

12

ADDENDUM 1: DESCRIPTION OF WATER REDUCTION PROJECTS 1. AUDIT, ANALYSIS, AND PLANNING Intent: To develop a detailed database of water management best practices, water-consuming systems, water reduction projects in order to coordinate targeted water reduction strategies. UCSF staff will perform audits and update the Water Action Plan database. Strategy: Conduct site visits and collect data and interview all staff with knowledge of or expertise in UCSF’s water infrastructure and water consuming systems.

Staff include: 1. Engineering & Trades Managers and Supervisors 2. Campus Chief Engineers 3. Landscape & Irrigation Supervisors 4. Building Commissioning and Controls Manager 5. Senior Associate Director and Associate Director of Engineering & Energy Services (includes utilities services) 6. Laboratory Managers Site visits include: 1. Campus Sites 2. Laboratories 3. Areas containing water consuming devices, equipment, and fixtures such as mechanical rooms, restrooms, kitchens, recreational facilities

and lawns. Status: Staff interviews have resulted in the development of projects and strategies that address water reduction efforts throughout the university. Many of these projects and strategies are included in the WAP. UCSF staff will refer to the UC Santa Barbara LABRats program as a model for research practice and water conservation. Further, site visits have yielded additional opportunities for water reduction. For example, a visit to a mechanical room resulted in the discovery of a portable water-cooled air conditioning unit that staff used to cool the room. After measuring the ACU’s continuous flow, staff calculated that the ACU discharged water to the sewage drain at a rate of one gallon per minute or 565,600 gallons/702.7 CCF per year. The impact of disconnecting this unit and insulating the HHW pipes to control the room’s temperature represents ¼% reduction in water consumption and counts towards the 2% reduction in the Additional Strategies category. As the audit discovers more opportunities for water reduction, those opportunities will be added to existing projects where appropriate and will contribute to the 20% water reduction goal. Summary: The impact of ongoing auditing is expected to be substantial and will affect the development and implementation of water reduction projects and strategies over the years. 2. SUBMETERING Intent: Used in combination with city-owned water meters, the submetering program provides both comprehensive and critical information about potable water distribution and helps guide the development of water reduction projects and strategies. Strategy: To connect submeters at critical locations to best determine water consumption trends and to locate areas to target reduction programs.

13

Status: In Progress. The Parnassus Campus has installed over 50 submeters at potable water delivery points with plans to install additional submeters to monitor RO/DI distribution from the Central Utility Plant (CUP) to the buildings, and to monitor water committed to irrigation. The submetering program is expanding to the Mission Bay Campus and other campuses and expected to produce the same level of insight as the program has done on the Parnassus Campus. Summary: The submetering program’s initial results have been very successful in providing important information about water consumption throughout the Parnassus Campus. This detailed data provides opportunities to develop targeted projects and strategies that are likely to have a tremendous impact on achieving and maintaining our water reduction goals. For example, the submetering program has verified that a substantial amount of water is devoted to continuous flow. Staff has used this information to initiate the Audit, Analyst, and Planning project to better understand the water consuming habits of end-users and their water consuming devices, equipment and fixtures. 3. PURIFIED WATER PROCESS REJECT/REUSE Intent: Because the ratio of potable water to RO water production is 4:1, there is a tremendous opportunity for savings through utilization of RO reject water for Cooling Towers makeup and for irrigation. Strategy: Divert RO reject water that is discharged into the city’s sewer system to use water in water systems that do not require ultrapure water such as Cooling Tower makeup and irrigation. Status: The Parnassus Campus Central Utility Plant implemented an RO Reject/Reuse program in 2007 that diverted reject water for use as Cooling Towers makeup water and estimates an annual savings of 3.50 millions of gallons in potable water that would otherwise drain to the city’s sewer system. The Mission Bay Campus power plant (PUP) also generates RO water and distributes it to each building. Preliminary planning is scheduled to begin in FY13-14 to determine how to implement an RO Reject/Reuse program at the Mission Bay Campus and also at the Mission Center Building and Mt. Zion Cancer Research Center. Summary: The impact of the RO Reject/Reuse program has been substantial contributing to a 2.9% reduction in potable water consumption on the Parnassus Campus during the benchmark period and annually since then. We expect to achieve similar results at the other campuses. 4. PURIFIED WATER REDUCTION Intent: Because the ratio of potable water to RO water production is 4:1, there is a tremendous opportunity for savings through reducing the amount of RO water produced on site. Strategy: Submeter RO/DI water distribution to each building to determine where demand is heaviest. Audit end-users’ RO/DI water use and determine if alternatives are available. Status: The submetering program is in the preliminary planning stage for installing submeters to measure RO/DI water distribution. The audit is in the development stage and active auditing should begin in FY13-14. Summary: Providing RO/DI is essential to the research activities of campus users. RO water production is also a major consumer of potable water. It is not clear that all systems that currently use RO/Di water require it so a submetering and audit program should determine where RO/DI distribution can be curtailed resulting in reduced RO water production.

5. FIXTURES UPGRADE Intent: Replace older, inefficient fixtures with ultra efficient or high efficient fixtures and save 2.287 millions of gallons of water annually. Strategy: UCSF CLS Facilities Services contracted with an outside vendor to perform an audit of water fixtures in 2011 for the Parnassus Campus and in 2013 for the other campuses. The audit provided an extensive database of fixture models, age, and flow rates that Facilities is using to target replacement projects at the Parnassus Campus and Mission Center Building. Facilities will replace fixtures at Mt. Zion Cancer Research Center as they fail since these already meet efficiency standards. The Mission Bay Campus already has high efficiency fixtures. Status: The fixture replacement at Parnassus Campus and Mission Center Building is complete. Summary: The fixture replacement project addresses the sanitary water system that an internal audit estimates consumes 57% of all potable water on the Parnassus Campus with similar projections expected for Mission Bay and even higher levels at Mission Center Building. The projected annual savings is about 5,000,000 gallons per year or about 2.2% of total water consumption. 6. LABORATORIES Intent: To implement best practices in sustainable laboratory processes, identify and replace or modify once-through cooling systems, identify and replace or modify autoclaves and sterilizers, replace high-volume faucets with spring-loaded faucets, and work with campus researchers to reach utility reduction goals. Strategy: Perform a detailed audit of laboratories to develop and reinforce best practices for conserving water. Status: UCSF has performed a pilot program of retrofitting autoclaves with quench kits resulting in a water consumption reduction of approximately 30% for each retrofitted autoclave. We intend to expand the program further at Mission Bay, Parnassus, and Mt. Zion campuses. UCSF staff is also working with laboratory and facilities staff to identify once-through cooling systems for retrofitting. Summary: UCSF expects to achieve substantial water reductions through retrofitting or replacing old or inefficient laboratory equipment and through laboratory staff using best practices to reach a 2.1% reduction in water consumption. 7. IRRIGATION Intent: Reduce the amount of potable water committed to irrigation needs by 4.0 millions of gallons. Strategy: Continue to monitor CalSense and other submeter data to determine the amount of water of the total consumption rate that is devoted to irrigation and develop strategies. Preliminary data shows that approximately 8.0 million gallons annually is devoted to irrigation needs. Summary: Irrigation represents great potential for potable water use reduction. Once we are able to establish definitive consumption numbers, we can take action to reach the 4.0 million gallon annual reduction through Also, at Mission Bay’s two large turf areas, irrigation water that is not absorbed into the ground drains into the city’s sewer system. Installing a water capture cistern at these drains and recirculating this water into the irrigation system could provide substantial savings. Additional alternatives include replacing the existing sprinkler systems with drip systems and replacing turf and water consuming plants with drought resistant, native or adapted species.

8. PM PROGRAM Intent: Reduce potable water consumption through a beefed up PM Program that inspects and repairs water consuming fixtures, devices, and equipment (university owned) on an annual basis to save approximately 4.5 million gallons of potable water by 2020 and .5 million gallons annually. Strategy: Inspect all university-owned water consuming devices, equipment and fixtures and make minor repairs. Generate database of conditions and repair work completed or recommended for medium to major repairs. Status: A pilot PM Program is in progress at the Mission Bay Campus. Inspections and minor repairs are in progress at Mission Center Building, Laurel Heights Campus, and Mt. Zion Cancer Research Center. A PM Program is under development at the Parnassus Campus. Summary: Preventive Maintenance programs have already proved their value in providing promoting asset management and providing cost savings over the long term. Strengthening the PM program for water consuming devices, fixtures and equipment requires an additional investment in resources, but the long-term impact should be considerable. 9. RECYCLE WATER FROM DISTRIBUTION AND RETURN SYSTEMS Intent: To recycle water from the water distribution and return infrastructure focusing on continuously improving steam, condensate return, heating hot water, chilled water and domestic water. Status: Continue the efforts begun at the Parnassus Central Utility Plant and apply to Mission Bay and other campuses. Summary: The Parnassus Central Utility Plant reduced consumption by millions of gallons annually during the benchmark period by improving the various distribution and return systems. 10. LEAKS AND CONTINUOUS FLOW Intent: Eliminate leaks and reduce continuous flow. Status: Submetering has provided clarification where leaks and continuous flow are occurring. The next step is to find the sources and address. Summary: Now that we can quantify how much water is lost to leaks and how much continuous flow occurs during off-hours, we can target those areas where these events are happening and either eliminate them altogether or reduce their impact potentially saving millions of gallons of water per year. 11. ADDITIONAL STRATEGIES Intent: To explore and implement alternative strategies for additional savings in water consumption. Strategy: Strengthen the water management program, explore and incorporate new technologies in our water consuming systems, study examples of water-saving projects executed at other institutions and organizations, and continue to evolve our approach to reducing water consumption as needs change. Summary: The following are examples of water-saving projects that UCSF is considering or is implementing. Examples:

A. Work with Capital Programs to minimize water used during construction. B. Review water consumption in animal care facilities and develop efficiency programs.

16

C. Remove, replace, or retrofit all once-through water consuming devices and equipment. This part extends beyond equipment and devices located in laboratories to other areas such as mechanical rooms and kitchens.

D. Continue to analyze cooling tower cycles of concentration to achieve the highest level of efficiency while maintaining the longevity of equipment.

E. Replace fixtures in campus housing. F. Reduce the frequency that Transportation Services washes its fleet of vehicles. G. Rainwater Harvesting: UCSF staff is investigating the option of installing rainwater collection devices on the roofs of buildings at Mission Bay

and Parnassus to use in cooling tower makeup and/or irrigation. H. Audit Animal Labs: Perform a detailed audit of animal labs to address any additional potential reduction in potable water consumption. I. Mission Bay Campus is included in the SFPUC’s Eastside Recycled Water Project that is in the planning stage. Water from this project will be

diverted to meeting irrigation needs. SFPUC is still developing this program so a timeline is uncertain. J. Wastewater Treatment and Recycling: The San Francisco Public Utilities Commission headquarters incorporates a Living Machine that treats

blackwater and greywater that comes from the building’s toilets, urinals, and sinks. The SFPUC headquarters is located in the very dense Civic Center neighborhood with the Living Machine incorporated into the building design, extending under the building and surrounding sidewalks. The Living Machine treats 5,000 gallons of wastewater per day and satisfies 100% of the demand from the building’s low-flow toilets and urinals in a 277,500 sf building with over 900 occupants. UCSF

10. OUTREACH AND ENGAGEMENT Intent: To raise awareness and encourage engagement of staff, students, faculty, and researchers to reduce water consumption an additional 2-3 million gallons of water annually by 2020. Strategy: A collaborative and coordinated effort between UCSF’s sustainability committees and programs, Campus Life Services, CLS Facilities Services, Capital Programs and other organizations to raise awareness and engagement through multiple efforts such as:

Provide live consumption data and progress reports to campus users with digital displays in key public areas

Easy access to consumption data for building and lab managers

Distribute and install print media in key areas to raise awareness and to provide instructions on reporting leaks and offering best practices tips

Engage campus members in challenges to take an active role in reducing per capita consumption Summary: Outreach and Engagement has the great potential to generate results that are continuous, long-term and that provide substantial cost-effective water reduction savings.

ADDENDUM 2: REGULATORY CONTEXT State Level

Recognizing the need to address a “growing population, climate change and the need to protect and grow California’s economy while protecting and

restoring our fish and wildlife habitats,” California’s legislature amended the state’s water code, Division 6, and with the Governor’s signature enacted

Senate Bill SBX7-7 in 2009. SBX7-7 requires the state to achieve a 20% reduction in urban per capita water use by December 31, 2020.9 Additionally,

CALGreen also referred to as the California Green Building Standards Code (Part 11 of the California Code of Regulations, Title 24 or the aka California

Building Standards Code) includes provisions that apply “to the planning, design, operation, construction, use and occupancy of every newly constructed

building or structure . . . throughout the State of California . . . and to the extent permitted by California law, buildings designed and constructed by the

Regents of the University of California and regulated by the Building Standards Commission.”10 The 2013 California Plumbing Code provides minimum

water efficiency requirements for non-residential and residential buildings in the State of California.

UC System-Wide Level

The University of California Office of the President adopted the Sustainable Practices Policy. Chapter III, Section I, subsection 1 specifically addresses

sustainable water policies, and asks each campus to strive to reduce potable water consumption adjusted for population growth by 20% by the year

2020.11 UCSF began initiating programs in 2007 to meet this goal.

Local Level

UCSF works with the San Francisco Public Utilities Commission (SFPUC) on water use and conservation issues. The collaboration has been a tremendous

benefit to UCSF with respect to planning and implementing water conservation programs, and in some cases, UCSF is able to take advantage of incentive

and rebate programs that the SFPUC offers.

ADDENDUM 3: CLIMATE AND GEOGRAPHY Regional Climate and Geographic Context

Located at 37.7833° N, 122.4167° W in a land area of 46.87 square miles at the north end of the San Francisco Peninsula12, the American Meteorological

Society characterizes San Francisco as a mesothermal climate with moderate temperatures.13 The Koppen-Geiger climate system classifies San

Francisco’s climate as Csb or Mediterrean with dry, mild summers and wet, mild winters.14

Relying on a single source location for San Francisco’s climate data may not be the best approach to developing water conservation strategies since

multiple microclimates and sub-microclimates exist within city limits.15 The combination of a heavier, prevailing summer marine layer that rushes in to

replace rising, hot inland air and an undulating topography contribute to temperatures that “can vary as much as 9°F (5°C) from block to block.”16 The

phenomenon of the marine layer is a result of warm, moist air masses that drift over the colder waters of the coast creating fog that typically moves a

short distance inland before evaporating.17 In addition, topography plays an important role in determining the vertical path of air as it moves through

the city affecting both relative humidity and air circulation differently in small geographic areas.18

UCSF addresses climate’s affect on building systems and water consumption locally at each campus

site. For instance, the cooler conditions at Parnassus Campus may lead to lower demand on cooling

towers that translates to less makeup water needed to operate the tower. The SFPUC provides a

microclimate map that the WAP refers to in the site-specific descriptions.19

The Parnassus Campus, the most populated of the five UCSF campuses, resides in Zone 1, Laurel

Heights Campus and Mt. Zion Cancer Research Center both reside in Zone 2, and Hunter’s Point,

Mission Bay Campus and Mission Center Building reside in Zone 3.

Zone 1: COASTAL (Fog Belt)

Cool temperatures, dense summer fog, salty air, prevailing westerly winds west of the

mountain slopes.

Marine influence strongest along coastline (Zone 1A). Diminishes inland (Zone 1B).

Potentially, less evaporation at Cooling Towers.

Zone 2: TRANSITION

Cool to moderate temperatures.

Light fog to clear, sunny skies.

Winds diminish east of the mountain slopes.

Zone 3: BAY (Sun Beltl)

Warm temperatures, notable in the mission district. (Mission Center Building and Mission Bay)

Dry, clear, sunny skies.

Light to high winds.

Higher evaporation rate, greater irrigation needs,

What are some ways that UCSF more accurately accounts for the possibility of climate’s impact on building systems and water consumption? At the

Parnassus Campus where conditions often vary substantially from official readings at SFO 20 nearly miles away, Central Utility Plant staff constructed a

climate monitor on top of the plant to obtain more accurate climate data to develop historic trends and compare that to energy and water consumption

on the campus. The expectation is that over time, staff will be in a better position to anticipate utilities consumption, both energy and water. Although

the verdict is still out, UCSF is addressing the possible impact of climate conditions at system-wide and local levels with remedies tailored to each

campus sites unique environment.

ADDENDUM 4: PHYSICAL DESCRIPTION

UCSF includes two major campuses and several additional sites in the city of San Francisco. The Parnassus Heights Campus is the older of the two major

campuses by far and has an average daily population of 16,000 people.20 The Parnassus Campus also contains the UCSF Medical Center, Ambulatory Care

Center, and Benioff Children’s Hospital facilities that are not part of this report. UCSF Parnassus Campus includes research, teaching, recreational, clinical,

administrative, and conference facilities. Mission Bay, the newer of the two major campuses, has an average daily population of 4,000 people.21 This will

increase to 9,000 when buildout is finished in 2020. Smaller sites include the Mt. Zion Cancer Research Center, Mission Center Building, and Laurel

Heights Campus.

The combined area of all buildings considered for this report is approximately 6.115 million sf. The oldest building in this survey opened on the Parnassus

Campus in 1917. Additionally, nearly 70% of all space has crossed major capital thresholds and await component system replacement. An additional 18%

of space will reach the 50 year mark within the next 10 years. The age of a majority of UCSF’s structures presents hurdles for implementing major

renovations that could dramatically improve water conservation efforts. The WAP will address the specific physical context of each campus in Addendum

6 of this report.

ADDENDUM 5: WATER SOURCE The SFPUC provides water to UCSF and another 2.6 million residential, commercial and industrial customers via a complex water supply network of

reservoirs, tunnels, pipelines, and treatment systems stretching from the Sierras through Alameda and Santa Clara counties to the San Francisco

Peninsula. “Two unique features of this system stand out: the drinking water provided is among the purest in the world; and the system for delivering

that water is almost entirely gravity fed, requiring almost no fossil fuel consumption to move water from the mountains” to customers. “The Hetch

Hetchy watershed, located in Yosemite National Park, provides approximately 85% of the total water supply.” The remaining water is sourced mostly

from the Alameda and Peninsula watersheds.22

ADDENDUM 6: SITE SPECIFIC DATA

6.1 LAUREL HEIGHTS CAMPUS, 3333 California Street

Site Description: In Zone 2 of SFPUC’s microclimate map, Laurel Heights Campus includes two buildings containing a total of 470,135 square feet

and an enclosed parking structure all of which are contained within a turf lawn of 138,168 sf.

Water Infrastructure: Three mains deliver potable water to the campus.

Challenges: The planned sale of Laurel Heights Campus to a private developer is impacting the water reduction strategy options. Irrigation is a

large consumer of water (potentially 80% of all potable water consumed) with a lot of this water going directly to the drain. CLS Facilities staff

has engaged SFPUC to perform a survey and provide recommendations for improving landscaping and irrigation, however, the payback extended

well beyond a feasible timeframe so CLS Facilities staff is considering other options with the greatest impact in the shortest term and low cost.

Facilities staff recently has installed one irrigation meter that should provide actual consumption data that we can use as we assess our options.

ADDENDUM 7: STORMWATER MANAGEMENT San Francisco is the only city in California that relies on a combined sewer system where both sewage and stormwater collect in the same piping network, travels to one of three treatment plants, and then discharges into the San Francisco Bay or Pacific Ocean.

UCSF construction projects are required to implement stormwater control measures, but only those projects at Mission Bay have reporting requirements per the California Environmental Protection Agency State Water Resources Control Board.23 The UCSF Office of Research: Environment, Health and Safety coordinates the approval and permitting process for projects that disturb >1 acre of soil.
