,�',UBJECT: REVIEW OF THE GRAND JURY REPORT "FLOODING AIIEAD: PLANNING
FOR SEA LEVEL RISE"
It is recommended that the Environmental Subcommittee of the City Council review the
Civil Grand Jury report titled "FLOODING AHEAD: PLANNING FOR SEA LEVEL
RISE" and the draft response from staff and provide input on changes to be incorporated
for full City Council consideration at the August 26, 2015 meeting.
BACKGROUND/DISC US SION
A Civil Grand Jury issued a report (Attachment 1) on June 4, 2015 entitled "Flooding Ahead:
Planning for Sea Level Rise," The report includes 12 findings along with 7 recommendations to
address the effects of sea level rise (SLR) over the remainder of this century. The report generally
finds that San Mateo County is at severe risk for SLR and that a coordinated countywide approach
does not exist to address associated flooding,
The Grand Jury requires a response from the governing body of every municipality within San
Mateo County, the County of San Mateo, the City/County Association of Governments of San
Mateo County, and the San Francisquito Creek Joint Powers Authority. The City Council must
respond to the findings and recommendations in the report by September 3, 2015 (see Attachment
2 beginning on page 31). Staff has reviewed the findings and recommendations and has prepared a
response letter for your consideration (see Attachment 3 beginning on page 33). In general, the
response letter indicates the City agrees with most findings and disagrees partially with a few, and
that many of the recommendations require coordination with other agencies and cannot be
implemented within the six months required by the Grand Jury.
There would be no fiscal impact associated with responding to the Grand Jury. Future funding
considerations will be brought to the City Council in conjunction with implementation of any of
the recommendations of the Grand Jury.

CONCLUSION
The Grand Jury report on SLR places this regional concern before all agencies within San Mateo
County. Staff will incorporate any recommended changes to the draft response to the Grand Jury
and present the revised letter to the full City Council at the August 26, 2015 regular City Council
meeting. This will allow sufficient time to submit the final response from the City by the
September 3, 2015 deadline established by the Superior Court of San Mateo County.

ISSUE
What actions can the County of San Mateo, and the 20 cities and two relevant local special
agencies within the county, take now to plan for sea level rise?
SUMMARY
San Mateo County is at severe risk for sea level rise (SLR) over the period 2015 -2100. The
County, and the 20 cities and two relevant local special agencies within the county, I do not have
a coordinated approach to address existing problems related to flooding and are not prepared for
the added challenge of SLR. This investigation documents the countywide risk that SLR poses to
people, property, and critical infrastructure. For example, wastewater treatment plants are highly
vulnerable to SLR and this vulnerability presents significant problems for all cities, not just those
along the coast and bay.
This Grand Jury report discusses ways to get organized to plan for SLR, as well as alternative
sources of funding for SLR-related projects, Based on this investigation, the Grand Jury
recommends that a single organization undertake SLR planning on a countywide basis. This
report also examines ways to address SLR as part of local land use planning and recommends
including SLR-related policies in local General Plans. It also recommends implementation of a
coordinated program to raise public awareness of SLR, particularly as to how it may impact this
county. Finally, the report highlights the need for effective and coordinated advocacy at the
regional, State, and federal levels.
The Grand Jury strongly urges action now to undertake countywide planning for SLR. By acting
now, SMC may be able to reduce future costs by integrating SLR-related projects with other
programmed levee projects, such as those that may be triggered by new FEMA flood hazard
maps. By acting now, San Mateo County jurisdictions may apply land use planning measures to
mitigate future exposure to SLR. Finally, by acting now to address SLR, San Mateo County can
also address the lack of coordination among jurisdictions that is evident in existing flood
prevention efforts. Notably, this lack of coordination places the county at a severe disadvantage
when applying for federal or State monies for flood protection.

BACKGROUND
San Mateo County (SMC) residents are at severe risk for flooding due to projected sea level rise
(SLR) over the period 2015-2100. In fact, SLR is already occurring. Measurements at the San
Francisco Tide Station at the Golden Gate show eight inches of SLR between 1897 and 2006,
consistent with figures from around the world.3
The precise amount and rate of SLR are unknown, but State agencies have consistently advised
that seas are rising at "accelerating rates," and project SLR ranging up to 65 inches (167
centimeters) by the year 2100.4 One scientist advised SMC officials of the possibility of even
greater SLR, nearly 15 feet, during this Century.5
2 A "100-year-storm" is used to define a rainfall event that statistically has a one percent chance of occurring in any given year.
However, it is riot the storm that will occur once every 100 years. Rather, it is the rainfall totals that have a one percent chance of
being equaled or exceeded each year.

Commission (BCDC), Living with a Rising Bay: Vulnerability and Adaptation in San Francisco Bay and on Its Shoreline, Staff
Report, October 6, 2011, p. 18.
4 in 2008, Governor Schwarzenegger issued an executive order requiring State agencies to prepare SLR scenarios for the years
2050 and 2 100 to "assess project vulnerability, reduce expected risks, and increase resilience to sea level rise," In response, the
Coastal and Ocean Working Group of the California Climate Action Team (CO-CAT), representing 17 State agencies, proposed
interim SLR projections for the year 2 100 ranging from 31 to 69 inches, grouped into "low." "medium, " and "big])" models
(based on a 2009 CEC study). For some planning purposes, agencies such as BCDC focused on 55 inches of SLR, the average
projection in the "high" model. However, CO-CAT urged agencies to "select SLR values based on agency and context-specific
considerations of risk tolerance and adaptive capacity," (See BCDC, Living with a Rising Bay, pp, 9, 2022.) In 2012, the
National Research Council (NRC) issued a report Sea Level Rise for the Coasts of California, Oregon and Washington: Fast,
Present and Fulare. The report projects SLR ranging from about 16 inches to 65 inches (42 to 167 centimeters) by the year 2100.
The NRC report was commissioned by California, Oregon, and Washington State agencies, by the National Oceanic and
Atmospheric Administration (NOAA), the U.S. Army Corps of Engineers, and the U.S, Geological Survey. CO-CAT now
considers the NRC report to be the "best available science" on SLR for this state, but allows State agencies to use the projections
"in a flexible manner" in their assessments or decisions. (See CO-CAT, Sea-Level Rise Guidance Docinnent, March 2013, p, 1,
and California Coastal Commission (CCC), Draft Sea Level Rise Poliqy Guidance, October 14, 2013, p. 4.)

In
Scientists have identified the major sources of SLR: an increase in water temperature causing
expansion of the oceans, plus the addition of water from melting glaciers.6 Based on scientific
studies, State agencies warn that additional SLR is now inevitable.?
Most discussions of SLR focus on the cause (climate change) and means of prevention (such as
reducing carbon emissions). This Grand ,fury report is not about preventing SLR, but rather about
adaptation to SLR. Adaptation includes measures such as constructing or modifying levees,
elevating structures, restoring wetlands, or abandoning low - lying areas.
This report addresses SLR that is projected to gradually increase through the year 2100,
Although this may seem to stretch far into the future, it is within the Iifespan of younger
residents and the useful life of many existing buildings and infrastructure. Substantial areas of
the county are already within existing FEMA flood insurance rate maps, Unless better protected,
these areas could feel the first impact of SLR at any time.
Over the last 20 years, there have been incidents of severe flooding in SMC. In December 2014,
low -lying basins and levee over - topping were contributing factors when a moderate "five- year "s
storm left hundreds of residents homeless.9 If the County, cities, and two relevant local special
agencies are struggling to address existing flood conditions, how will they handle worse
conditions in the future? 10

6 The risk is not just SLR alone, that is, a slow rise in sea level until one day the levees are topped. For one think, SLR can
undermine the integrity of existing levees. Even more, the risk lies in the combination of SLR., plus the yearly high tides ( "king"
tides), plus a l 00 -year storm that causes a storm surge and crave action in the Bay, plus heavy rainwater runoff in creeks. Other
factors that influence the risk of hooding due to SLR include changes in land elevation due to earthquakes, and the subsidence, or
sinking, of land such as that caused by excess pumping of groundwater. See BCDC, Living with a Rising Bay, p. 4; and see

millennia." BCDC, Giving with a Rising Bay, p, 9.

Interviews
In conducting this investigation, the jury interviewed 14 individuals including two elected
officials; four city managers or assistant city managers; four executive directors, general
managers, or assistant general managers of three joint powers authorities; and four County of
San Mateo appointed officials.
San Mateo County's Exposure to Sea Level Rise
As noted earlier, State agencies project SLR within a range of up to 65 inches by 2100. A 2012
report, prepared by the Pacific Institute for the California Energy Commission (CEC), documents
the potential impacts on areas around San Francisco Bay of sea level rise of 16 inches by 2050
and 55 inches by 2100.1'
The results of the CEC study are startling. Of all the counties in California, SMC is by far the
most exposed to SLR, in terms of both the residents and economic value at risk. Assuming 55
inches of SLR, the replacement value of buildings and contents at risk of flooding along the bay
is estimated to exceed $23 billion, while that along the coast is valued at $910 million (land
value is not included in these figures), 12 This is about one-quarter of the statewide total and
nearly 40% of the Bay Area total. The dollar figure only hints at the threat to the people and
structures within SMC due to SLR:
120,000 residents at risk of losing their homes to flooding (also nearly one-quarter of the
statewide and 40 percent of the Bay Area totals) 13
a 110,000 employees at job locations at risk
I I Hebergeret al., The Impacts of Sea Level Rise, pp. 6-21. As noted in the discussion in footnote 4 of this Grand Jury report, 55
inches is the average of "high" model projections. Thus, it represents a close-to-worst-case scenario (excluding catastrophic SLR
discussed elsewhere in this report).

The Grand Jury reviewed SLR flood maps prepared by the Pacific Institute, which show the
impact of 55 inches of SLR, 14 These maps are included in the Appendix. All of Foster City and
substantial areas of Redwood City and San Mateo could be inundated. Serious flooding could
also occur in East Palo Alto, Menlo Park, San Carlos, Belmont, Burlingame, Millbrae, San
Bruno, and South San Francisco.
The 55-inch SLR flood zone covers important commercial centers including part of South San
Francisco's biotech industrial area, the hotels along Burlingame's shoreline, numerous shopping
areas, business parks, and recreational spaces. Within this floodplain are the headquarters of Visa
International in Foster City, Franklin Templeton Investments in San Mateo, Oracle in Redwood
Shores, and Facebook in Menlo Park.
Fifty -five inches of SLR waters would flood San Francisco International Airport and the
County's Half Moon Bay and San Carlos Airports, Other County facilities at risk include the
new jail under construction and the Government Center, both in Redwood City, The Caltrain line
in San Mateo, Burlingame, and Millbrae is threatened. The Port of Redwood City and marinas
operated by the County Harbor District at Pillar Point on the coast and at Oyster Point in South
San Francisco could be flooded.
The new Kaiser Foundation hospital in Redwood City, the Kaiser Foundation medical office
building in San Mateo, the new Palo Alto Medical Foundation medical office building in San
Carlos, and the Stanford Health Care medical office buildings in Redwood City are all within the
55-inch SLR flood zone.
On the coast, parts of Half Moon Bay and Peseadero could be flooded. In Pacifica, the potential
for SLR has "very serious implications ... areas of the Sharp Park Golf Course, the Rockaway
Beach district, and the West Linda Mar and West Sharp Park neighborhoods could be
inundated." 15 Further, "coastal erosion processes that have caused damage along the high bluffs
of Pacifica's northern neighborhoods would very likely increase in magnitude . . . while there

could be new risks of erosion along the length of Pacifica's coastline in areas that are not
currently exposed to wave action erosion.... "16
CountMide Impact—Tax Revenue
Although no exact figure has been calculated, it is evident that the impacts identified above
would also have a severe effect on tax revenues from a variety of sources. In particular, a
reduction in property tax revenue from SLR flood zones would affect all taxing entities in the
county. This might affect the provision of County and city services throughout the county.
!Countywide Impact—Wastewater Treatment Plants
The impact of SLR is not limited to jurisdictions touching the ocean or bay. Inundation of
wastewater treatment plants would pose severe countywide environmental and health threats.
Since sewer systems rely on gravity, treatment plants are often located at sea level, with outflow
of treated wastewater into the bay or ocean. The CEC report identified the following plants in
SMC as vulnerable with 55 inches of SLR: 17
• Mid-Coast Sewer Authority (includes the city of Half Moon Bay)
• City of Millbrae
• San Francisco International Airport
• City of San Mateo (includes the city of Foster City and part of the town of Hillshorough)
• South Bayside System Authority (now Silicon Valley Clean Water) (includes the cities
and towns of Atherton, Belmont, East Palo Alto, Menlo Park, Portola Valley, Redwood
City, San Carlos, and Woodside)
• South San Francisco/San Bruno (includes the town of Colma)
In addition to the threat of flooding, it is likely that these plants, and others that pump their
treated water into the bay or ocean, will also need to install stronger pumps in order to deal with
the increased water pressure at depths That will have increased due to SLR, Is
The State CO-CAT advises that shoreline wastewater treatment plants with no space to relocate
inland have "low adaptive capacity and high potential impacts from flooding." For such
facilities, preparing for a higher projected SLR would be prudent, 19

components have been elevated to protect against possible levee failure. However, this does not
take into account SLR. Also, staff noted that the treatment plant receives wastewater from four
pumping stations, all of which are in the SLR flood plain,20
Catastrophic Sea Level Rise
A 2013 National Geographic Magazine article described potential SLR of 212 feet, over many
centuries. 2 1 In a presentation to SMC officials, oceanographer John Englander said that a I0 -foot
rise over just 10-15 years is possible this century if two west Antarctic glaciers break loose into
the ocean. 22 This would be in addition to the SLR already projected by State agencies. This
Grand Jury report looks at the local planning required for up to about 55 inches of SLR. At this
level, SLR impacts SMC to a much greater extent than other Bay Area counties, and it makes
sense to look at this county separately. However, SLR on the order of 15 feet or more would
severely impact the entire Bay Area and planning may need to be addressed primarily at the
regional level.
SLR Is a Countywide Issue
A key question is whether SLR should be viewed as a countywide threat or only as a risk to areas
threatened with actual inundation. The answer to this question has important implications for
how the problem is addressed—and who pays for it.
Currently, flood control, whether along creeks or shorelines, is the responsibility of each city, as
cities have responsibility for public safety and for land use. In fact, exposure to SLR is partly the
result of land use decisions by cities to develop tidal wetlands and other low-lying areas.
However, as detailed above, the impact of SLR will fall on all county residents. In particular, the
exposure of wastewater treatment plants and the loss of countywide tax revenue are serious
countywide threats.
Public Awareness of the Threat
Developing a plan to adapt to SLR will require broad support arnong, elected officials and other
government policymakers and, most importantly, the general public. This, in turn, requires
greater public awareness of the issue.
Two forums on SLR sponsored by Congresswoman Jackie Speier, Assemblyman Rich Gordon,
and Supervisor Dave Pine have served to educate many local elected officials and government

model of "living with water": see also Larry Golftband (Executive Director of BCDC), Conference Speech at Speier, Gordon,
and Pine, "Meeting the Challenge of'Sea Level Rise." He noted the possibility of addressing SLR at the Golden Gate, rather than
along the entire length of the bay shoreline.

staff 23 However, as one city manager noted, continuing education is necessary as elected
officials rotate off their councils.
Moreover, despite some press coverage of the two forums, it appears that the public at large is
not well informed on the issue. At present, the Grand Jury is not aware of any on-going
educational efforts by local governments to inform county residents about SLR, particularly as it
may impact SMC.
Preparing for SLR
Existing Flood Protection in San Mateo County
Cities and two special local agencies are responsible for construction and maintenance of levees
within their jurisdictions, 24 Often, they pay the entire cost of levee projects. They work closely
with various regional, State, and federal permitting agencies to meet design standards, both for
the structures themselves and the adjacent shoreline enviromnent.25
Presently, there is a chain of levees along the bay. Each link in the chain is the responsibility of a
different city or special agency. However, flood risk is based on topography, not political
boundaries. Thus, the safety of properties in any given city often depends on levee projects
undertaken by its neighboring cities. The public is protected only so long as the "weakest link" in
the chain of levees is able to meet the threat. Officials interviewed by the Grand Jury identified a
number of existing "weak links."
Currently, no countywide agency has oversight of the levees as a whole. No agency provides
countywide planning, coordinates cities' construction and maintenance efforts, or assists with
grant applications related to existing flood problems, much less preparing for SLR. Cities do not
contribute money to pay for projects outside their jurisdiction, even though their own residents
may benefit.
The San Mateo County Flood Control District is "countywide" on paper but its tax base is
limited by the California Water Code to certain "subzones," which were specified prior to the
voters' adoption in 1978 of Proposition 13. The District's revenue strearn is small and limited to
funding flood control along the Colma, San Bruno, and San Francisquito Creeks. The District
has no staff of its own, contracting with the County's Public Works Department on all as-needed
basis for necessary staffing.

Current Efforts in San Mateo County to Plan for SLR2-1
The County has taken the lead in trying to jump-start the process of planning for SLR. Along
with working groups of elected officials, city staff, and special district personnel, the County has
commenced (a) conducting a vulnerability assessment, (b) exploring options for a countywide
governance organization to address flood control and SLR, and (c) identifying sources of
funding. In January 2015, the County's Office of Sustainability received a grant from the State
Coastal Conservancy (SCC) to jointly manage an SLR vulnerability assessment for SC. The
study will cover the entire bayside and the coast from Half Moon Bay north,27 VAfile there is
currently no guarantee, staff is confident that the Office of Sustainability will continue working
on SLR beyond the period of the grant.
Characteristics of a Possible Orizanization to Address SLR Plannin
Almost every local official interviewed by the Grand Jury acknowledged the need for greater
coordination among jurisdictions to address SLR. Each person was asked about options for
"getting organized" to address SLR. Sorne of the characteristics identified by many of those
interviewed include:
• The organization should be countywide, including upland and coastal communities.
• The cities should participate in decision-making by the organization.
• The organization should have afiocus on SLR and have a staff with expertise in the
subject.
• The organization must be sustainably funded.
Interviewees also identified a number of existing needs related to planning for SLR that should
be met.
® Identify consistent SLR-related projections and flood control project standards for all
jurisdictions
* Help coordinate jurisdictions regarding SLR-related flood control projects and seek a
commitment by Jurisdictions to implement projects in a timely fashion
26 Other important SLR-related efforts in SMC include the "SFO/San Bruno Creek/Colma Creek Resilience Study," a joint effort
of the airport, affected cities, and the County to assess SLR impacts in the vicinity of San Francisco International Airport
(Brendan P. Bartholomew.. "Peninsula Sea-Level Study to Focus on Flood Threats Surrounding SFO," San FralWiSCO Examiner,
February 13, 2014). The San Francisquito Creek JPA is undertaking two SLR- related projects: the SAFER Bay project will
protect property within the cities of East Palo Alto and Menlo Park from Bay 1017 -year tides with up to three feet of SLR and
enhance and create Bay marshes; and the San Francisco Bay to Highway 101 project along San Francisquito Creek that will
protect the tidally influenced areas of East Palo Alto and Palo Alto from a 100 -year creek flow coincident with an extreme tide
and 26 inches of SLR (http: 'sfcjpa.org/projects). In addition, the SCC is funding Local Coastal Plan updates for Half Moon Bay

However, several city managers and others questioned whether the cities are ready for a new
organization to assume direct control of levees, since such an organization might impinge on city
authority regarding public safety, land use, and use of eminent domain.
Organizational Options
The Grand Jury discussed the following organizational options for SLR planning with the
interviewees:
• Expanding the role of the County Flood Control District (SMCFCD) and/or the County
Office of Sustainability
• Creating a new independent special district with an elected board (such as the Santa Clara
Valley Water District)
• Expanding the role of the City/County Association of Governments (C/CAG)
• Creating a new joint powers authority (JPA) with an appointed board of elected officials
from the cities and County (and possibly- relevant special agencies)
The County option (first bullet point) offers advantages. As an existing agency, the Flood
Control District would not need to be created anew (although legislative action would be
required to expand its role). Its existing jurisdiction extends countywide, at least on paper.
County staff already has expertise in matters relating to flood control. Although separate, the
SMC Office of Sustainability is also developing staff with knowledge about SLR. The relevant
functions of the Office of Sustainability and County's Public Works Department (which staffs
the County Flood Control District) could easily be coordinated or merged. Both the Flood
Control District and the Office of Sustainability are responsible to the County Board of '
Supervisors. Therefore, a way would need to be found to ensure that cities may participate in
decision-making. Given its other responsibilities, some interviewees were also concerned that the
County Board of Supervisors might not be able to give SLR the focus it requires.
In the case of an independent special district with its own elected board (second bullet point),
neither the cities nor the County Board of Supervisors would have decision-making authority. It
is not a near-term option, since it would require voter approval, hiring of staff and acquisition of
office space, among other things. The Grand Jury's investigation also suggests that the creation
of a new district would be an expensive choice, particularly if the district's responsibilities are
limited to SLR planning. An independent special district might be a more appropriate option if
responsibilities included actual levee construction and maintenance,
The Grand Jury inquired as to whether C/CAG, which already has committees on several
environmental subjects, could expand its role to include planning for SLR. However, local
officials felt that C/CAG is strongly focused on congestion management and does not have
2014-2015 San Mateo County Civil Grand Jury
ago
expertise in SLR/flood control. C/CAG staff has not proposed to the agency's Board of Directors
that the agency take on S LR. 28
Creating a new JPA (fourth bullet point) would allow the cities (and County) to have a voice. A
JPA for SLR could hire staff with expertise in the field and, as a single-purpose agency, could
stay focused on SLR. One negative factor is the need to create a brand new governmental
structure and the added expense to do so. However, it is possible that the JPA could contract for
administrative services and staffing with another agency, such as the County. A second concern
expressed by local officials is the need to structure the JPA so that a membership that includes
the County, 20 cities, and possibly other relevant local agencies does not become unwieldy.
Based on this analysis, the Grand Jury concludes that, under current circumstances, there is no
perfect choice for an organization to undertake countywide SLR planning. However, it appears
that either enlarging the role of the County Flood Control District or creating a new JPA would
be viable options. What is critical is that a coordinated countywide approach be agreed upon
soon.
The costs of an organization that only focuses onplanning-type functions such as coordinating
local jurisdictions, conducting studies, developing standards and timelines, and preparing grant
applications would be much less than the cost of actual construction of levees. It could be funded
by member contributions, grants, and contributions from industry and wastewater treatment
agencies. This would be similar to the general fiend revenues that C/CAG currently collects from
member contributions and grants.
Funding of Projects to Protect against SLR
At the Grand Jury's first interview, a local official posed the following question regarding SLR,
"how are we going to pay for it?" Levee construction is extremely expensive. Projects recently
completed or proposed in the county, just to address existing needs, have run into the tens of
millions of dollars.29
Current Funding for Levee Protection in San Mateo Count
Currently, funding for levee projects comes mainly from local general funds or capital
improvement funds, plus, in some cases, an assessment on property owners who directly benefit
from such projects. Where relatively few properties are involved, the assessment per parcel can
be prohibitive.
28 Sour= Interview.
29 For example, in 2012 the City of San Mateo completed $22.7 million in levee improvements to protect 8,000 properties and
faces raising another $22.35 million for levee improvements to protect 1,500 properties that remain in FEMA flood insurance rate
maps (Larry Patterson, Conference Speech at Speller, Gordon, and Pine, "Meeting the Challenge of Sea Level Rise"). The San
Francisquito Creek JPA has secured State and local funding for its $37.5 million project for the portion of that creek between the
Day and Highway 101 (Germady Sbeyner, "San Frzncisquito Creek Project Sees Breakthrough after Permit Stall.."Pa/0 Alto
Online, November 3, 2014„ and interview).
2014-2015 San Mateo County Civil Grand Jury 12
NN
The cost of flood insurance to property owners is also expensive. As a result, cities focus on
projects that remove residents from FEMA flood zones (which determine the need for
insurance). Savings on insurance helps offset the cost of a property assessment.
Potential Countywide Sources of Funding for SLR Proiects
City general funds and assessments on properties that directly benefit may also be used for SLR-
related projects. However, since SLR has countywide impacts, spreading part of the cost
countywide appears justified, Some potential sources of countywide revenue include: 30
* Wastewater agencies may impose fees on customers within their service area to help pay
for levee projects that protect wastewater treatment plants and pumping stations
threatened by SLR.
* Officials interviewed doubt that, at present, SLR levee projects could secure the 66,7%
voter approval required under Proposition 218 for a special tax (i.e., a tax imposed to
raise revenue for a specific purpose). However, this could be a source of funds in the
future, when the threat of SLR becomes more evident,
* The County and cities may raise funds through general taxes, such as County Measure A
(2012), which require approval of a simple majority of voters, and distribute aportion of
such revenues to protect against SLR, so long as the measure does not include a specific
commitment to fund SLR projects.
* C/CAG used the simple majority voter threshold to win approval for County Measure M
(2010), a vehicle registration fee used for a variety of transportation projects and for
mitigation of transportation-related stormwater pollution.31 Any organization, such as the
County Flood Control District or a new JPA, that addresses SLR and other related issues
such as groundwater management and water pollution, might be able to use a similar
approach.
* State law (SB 628, 2014) allows for the formation of Enhanced Infrastructure Financing
Districts within cities and counties with the authority to issue bonds, with 55% voter
approval, for purposes such as "flood control levees and dams, retention basins, and
drainage channelS."32 In certain circumstances, such districts may be formed within SMC
jurisdictions to serve as a source of funding for SLR projects.
* Contributions may be solicited from business parks or agencies responsible for facilities
such as airports or highways that are within SLR flood plains. For example, the Facebook
headquarters campus in Menlo Park will benefit from the San Francisquito Creek JPA's
SAFER project, and the company has contributed $275,000 toward its design and EIR. 33
* Mitigation fees may be imposed on new developments in areas subject to SLR.

Potential Regional, State and Federal Sources of Funding for SLR Projects
To date, local cities have received little federal or State funding for levee projeCtS.34 Several
officials advised that granting agencies typically prefer projects that show multi-jurisdictional
cooperation, placing the local government entities in San Mateo County at a significant
competitive disadvantage in securing such funds. However, even for a multi-Jurisdictional
project, grants are highly competitive. SLR-related projects face a further difficulty if the
granting agency does not yet recognize the risk of SLR.. Finally, since SMC is by far the county
most vulnerable to SLR, it may be difficult to find other counties With similar needs with which
to collaborate on a regional basis. However, there is one new source of funding:
a The State of California's Climate Resilience Account, created in 2014, is a source of
grant funding directed specifically at SLR. Although only $2.5 million has been allocated
statewide in the first year, it may be enlarged in the future.
Reducing Costs by Integrating SLR-Related Projects with Other Levee Projects
Given that the amount and rate of SLR are uncertain, local officials may be reluctant to spend
large amounts of money for projects that may never be needed. Possible cost-saving options that
cities and relevant special agencies may examine on a case-by-case basis include: 35
• Integrating SLR-related protection with existing planned or proposed levee projectS36
• Developing SLR-related projects in stages, with specific "triggers" required before
undertaking each stage of construction
In order to take advantage of these cost-saving options, however, SLR planning should begin
now. For instance, a FEMA representative has advised county officials that new FEMA flood
hazard maps will be forthcoming in the near future. These maps will reflect a new higher
calculation of bay wave action during storms. This new calculation, which is independent of any
SLR effect, may trigger the need for new levee projects to keep properties in SMC from being
subject to flood insurance requirements. Incorporating consideration of future SLR in these new
projects may result in cost-savings later. 37
SLR Is a Land Use Issue
Levee projects are a common solution to SLR. However, they may not be feasible everywhere,
due to financial, environmental, or technical reasons. If the risk of flooding due to SLR cannot be
completely eliminated, the County and cities will need to examine land use measures to help
mitigate the threat of SLR.38 Possible land use measures include the following:
34 Notably, San Francisquito Creek JPA has received an $8 million State Water Resources Board grant for a multi - jurisdictional
project. (Source: Interview.)
35 Craig CODDef-_ U.S. Aimy Corps of Engineers.. Conference Speech at Speier, Gordon, and Pine, "Meeting the Challenge of Sea

I 00-year creek flow coincident with an extreme tide and 26 inches of SLR, (Source: Interview.)
37 Kathleen Schaefer, FEMA, Conference Speech at Speier, Gordon, and Pine, "Meeting the Challenge of Sea Level Rise.'"
38 Flood control levees themselves are local land uses, sometimes offering public trails, and vista points, and other recreational
options.

* Jurisdictions can include adaptation to SLR in the Safety Element of their General Plans.
While not required by State Guidelines,39 several cities in the county do mention SLR in
their Safety Elements and/or Climate Action Plans.40
* Jurisdictions may restrict new development or types of land use in areas subject to SLR.
* Jurisdictions may use building codes to mitigate SLR flood risk. For instance, they could
require habitable areas and key building equipment be placed above flood level,
* Jurisdictions may identify areas suitable for environmental resource protection and
habitat enhancement, in light, of the threat of SLR.
* Jurisdictions may need to identify certain areas to be abandoned to SLR.
* Jurisdictions may impose SLR mitigation fees as a condition of approval on major
residential or commercial projects in undeveloped areas subject to future SLR.
* Jurisdictions may use the CEQA environmental review process to ensure that exposure to
SLR is considered, and mitigation measures identified, when major residential or
commercial projects are proposed within a SLR flood plain.
Actions Needed at the Regional, State, and Federal Levels
While focused on SMC, this investigation points to the need for action on SLR at other levels of
government. The County, cities, and relevant local special districts, through their representation
at regional agencies, memberships in state associations, lobbyists, and elected State and federal
legislators, could advocate on our behalf. Some examples include:
0 Federal agencies, such as the U.S. Army Corps of Engineers, do not currently recognize
SLR in their flood control mapping and/or fanding.41
a Federal and State funding is extremely limited for all stages of adaptation to SLR:
studies, planning, and actual levee projects.
39 California Govemor's Office of Planning and Research, State of Cal General' flan Guidelines, 2003.
40 The City of Pacifica's draft Safety Element has a particularly comprehensive discussion related to SLR. However, the City
will wait for "an adequate model with sufficient local detail" to project specific impacts of SLR (see Dyett & 13hatia, City of
Pacifica Draft General Plan, March 2014, pp. 8-11 – 8 -10). The City of San Carlos approved a Climate Action Plan (CAP) as a
component of the City's General Plan update. The CAP includes a BCDC map of the city showing SI.R of 16 and 55 inches. The
City's approach to SLR is to cooperate with regional agencies, such as BCDC. (See City of San Carlos, Climate Action Plan,
October 12, 2009, pp. 2, 87 -91.) The City of Sari Mateo commissioned a report that includes a description of the potential effects
of SLR on that city and has appended the report to the City's General Plan. However, the General Plan states that "considering
that there is no definitive estimate and that sea level rise will occur slowly overtime, the City will continue to address FEMA's
current certification standards" (see City of Saar Alateo 2030 General Plan, 2010, pp. VII-6 and Appendix V, Schaaf & Wheeler,
Climate Change In7pactsfir San Mateo, Califoi-iiia).
41 This may change. "In accord with the Biggert-Water Flood Insurance Reform Act of 2012, FEMA is to establish a Technical
Mapping Advisory Council that will provide recommendations to FEMA on flood hazard mapping guidelines— including ... the
impacts of sea level rise.. , , FEMA will be required to incorporate future risk assessment in accordance with the
recommendations of the Council," (See FEMA. http://www.fema.gov'coasta1-ftequcntly-asked-

0 With just $2.5 million in this year's budget for statewide use, funding of the California
Climate Resilience Account, dedicated to SLR, is inadequate.
0 California General Plan Guidelines (2003), prepared by the Governor's Office of
Planning and Research, do not require that SLR be addressed in the Safety Element or
elsewhere in local general plans,
a, Regional agencies, such as BCDC, could provide a forum for discussing SLR, including
alternatives for addressing catastrophic SLR greater than 10 feet.
While these and other actions at the regional, State, and federal levels are important, it must be
emphasized that San Mateo County cannot afford to wait for planning and resources to appear
from outside the county. They may never come.
F1. SMC is at severe risk for flooding due to the gradual rise in sea level, projected at up to 65
inches (167 centimeters) by the year 2100. Catastrophic SLR of nearly 15 feet is a
possibility this century.
F2. SLR is a threat counom4de, including the upland areas. All residents depend on public
infrastructure, especially wastewater treatment plants. Also, a significant portion of the
countywide property tax base is within the area threatened by SLR.
F3. Although many local officials are now familiar with and concerned about the threat of
SLR, there is inadequate public awareness of SLR's potential impacts on this county.
F4. Levees, including their financing, are currently the responsibility of each individual city or
special agency with jurisdiction along streams, bay, and coast (the County is responsible
for unincorporated areas).
F5. Flood risk is based on topography, not political boundaries. The safety of properties in one
jurisdiction often depends on levee projects undertaken by another jurisdiction.
F6. Currently, no countywide agency exists to provide planning, facilitate coordination among
jurisdictions, or to assist with securing funding for existing flood control projects. The
same is true for future SLR-related projects.
F7. To the Grand Jury's knowledge, no local jurisdiction has adopted SLR projections or maps
for specific local land use planning purposes.42 No consistent SLR projection has been
adopted countywide by the County and cities.
F8. There is a recognized need for a countywide approach to SLR planning and coordination
among jurisdictions,
F9. Several city managers and others interviewed did not support having a new countywide
organization assume direct control of levee projects at this time.
F10. The County and cities can address SLR in their General Plans and Climate Action Plans,
can map the threat, and can adopt relevant policies,
42 See discussion of SLR planning in several San Mateo County cities in footnote 39.

Fl 1. Many actions to address SLR are within the authority of regional, State, and federal
agencies.
F12. By acting now, SMC may be able to reduce future costs by integrating SLR-related projects
with other programmed levee projects, and by using land use planning measures to mitigate
future exposure to SLR.
The Grand Jury recommends increased public education about SLR:
RI, The County, each city in the county and relevant local special agencieS43 should conduct a
public education effort to increase awareness of SLR and its potential effects on this
county,
The Grand Jury recommends identifying a single organization to undertake SLR planning:
RI The County, each city in the county and relevant local special agencieS44 should identify a
single organization, such as a new joint powers authority or an expanded SMC Flood
Control District, to undertake countywide SLR planning. It should be structured to ensure
that:
0 The organization is countywide in scope
0 The organization is able to.focus on SLR
Both the County and cities (and possibly relevant local agencies) are able to
participate in the organization's decision-making45
0 The organization is sustainably funded
R3. The organization's responsibilities should include:
a Adopt consistent SLR projections for use in levee planning countywide
• Conduct and/or evaluate vulnerability assessmentS46
• Provide a forum for inter-jurisdictional coordination and exchange of information
related to SLR
• Undertake grant applications for SLR - related planning and projects
• Facilitate raising funds on a countywide basis for SLR-related projects, to be passed
through to agencies with direct responsibility for project construction
43 San Mateo County Flood Control District and San Francisquito Creek Joint Powers Authority,
44 Ibid.
45 The organization could also create a technical advisory committee with representatives of departments responsible for levee
construction and management, as well as representatives of public facilities at risk, such as airports and wastewater treatment
plants.
46 A vulnerability assessment could (a) inventory areas at risk f!).r SLR (commercial, residential, public facilities, and
infrastructure), (b) detennine the adequacy of existing levee protection, and (c) identify and prioritize the projects that will be
needed to adapt to SLR,
2014-2015 San Mateo County Civil Grand Jury 17
M
• Monitor actual SLR over time and any changes in SLR projections, based upon the
latest federal, State, or regional government reports and scientific studies
• Through the CEQA environmental review process, comment on major new
developments proposed in the SLR floodplain
• Advocate on behalf of the member jurisdictions with federal, State, and regional
agencies regarding SLR issues
• Assist the County and cities in public awareness efforts, as described in RI
R4. The County, cities and two relevant local special agencieS47 should consider expanding the
role of the organization beyond SLR to include planning and coordination of efforts to
address existing flooding problems along the Bay, coast, and creeks that are subject to tidal
action. It may be cost-effective to integrate SLR protection with other levee-improvement
programs.
The County and cities may also consider expanding the role of the new organization to
include potentially compatible functions such as the National Pollution Discharge
Elimination System (NPDES), currently managed by C/CAG, and the new (2014) State
requirements for local sustainable groundwater planning.
R5. The organization—its administration, staffing, and program expenses—should be funded
on a sustainable basis by:
• Member contributions
• Contributions solicited from parties threatened by SLR, including corporations and
agencies that operate public facilities such as wastewater treatment plants
• Grants solicited from available potential sources such as the California Climate
Resilience Account
• Reducing administrative costs by contracting for services with the County or another
agency
The Grand Jury recommends that SLR be addressed in local land use planning:
R6. The County and each city should amend its General Plan, as needed, to address the risk for
SLR. The Safety Flement48 should include a map of any areas vulnerable to SLR, as
determined by measurements in the countywide Vulnerability Assessment [R3]. Further, it
should identify policies that apply to areas threatened by SLR.
47 San Mateo County Flood Control District and San Francisquito Creek Joint Powers Authority.
48 As an alternative, the City of San Carlos has addressed SLR in its Climate Action Plan (CAP). The City states that the CAP
was developed as a "component of the 2009 General Plan update . , . a legally defensible approach to ensuring that the Climate
Action Plan is implemented'" (see City of San Carlos, Climate Action Plan, 2009, p. 2).

The Grand Jury recommends that local governments champion SLR issues before regional,
State, and federal governments and agencies:
R7. The County, cities, and relevant local special agencies, through their representatives on
regional agencies, membership in state associations, lobbyists, and elected State and federal
legislators, should pursue SLR-related issues with government bodies outside SMC.

Sea level rise inundation maps for selected areas of San Mateo County are presented below. The
turquoise-colored zones represent the "current area at risk" to flooding during a 100 -year storm,
without consideration of existing flood protection levees. The magenta-colored zones represent
the area at risk during a I00 -year storm with 1.4 meters of SLR (140 centimeters or about 55
inches). The green - colored zones represent areas at risk of erosion from 1.4 meters of SLR, but
are not clearly distinguishable at the scale used in this Appendix. These maps were prepared by
the Pacific Institute, with specific infrastructure and major government and commercial facilities
identified by the Grand Jury with an *,symbol.

Subject: "Flooding Ahead: Planning for, Sea Level Rise"
Dear Judge Etezadi:
The City of South San Francisco (City) has reviewed the above referenced
Grand Jury Report filed on June 4, 2015. The following is the City's response to
the findings and recommendations of the report. Submission of this response
was authorized by the City Council at the August 26, 2015 meeting.
Fl. SIVIC is at severe risk for flooding due to the gradual rise in sea level,
projected at up to 65 inches (167 centimeters) by the year 2100.
Catastrophic SLR of nearly 15 feet is a possibility this century.
The City partially disagrees with this finding. The City acknowledges that there
have been numerous studies on projected sea level rise. The reports vary in
projections but consistently indicate future sea level rise, so the City cannot
confirm the specific figures Cited. The City agrees that areas of San Mateo
County are at severe risk for flooding due to gradual rise in sea level,
F2. SLR is a threat countywide, including the upland areas. All residents
depend on public infrastructure, especially wastewater treatment plants.
Also, a significant portion of the countywide property tax base is within the
area threatened by SLR.
The City agrees with this finding. In addition to the public infrastructure and
property tax base, the affected areas also generate a large number of jobs and
economic activity that benefit the entire county.
-33-
F3. Although many local officials are now familiar with and concerned
about the threat of SLR, there is inadequate public awareness of SLR's
potential impacts on this county.
The City agrees with this finding.
F4. Levees, including their financing, are currently the responsibility of
each individual city or special agency with jurisdiction along streams, bay,
and coast (the County is responsible for unincorporated areas).
The City agrees with this finding. The City does not currently have any levees.
Under the current jurisdictional responsibilities, any future levee construction
would be the responsibility of the City or the Colmadreel�' Flood Control District.
F5. Floodl risk is based on topography, not political boundaries. The safety
of properties in one jurisdiction often depends on levee projects
undertaken by another jurisdiction.
The City agrees with this finding.
F6,. Currently, no countywide agency exists to provide planning, facilitate
coordination among jurisdictions, or to assist with securing funding for
existing flood control projects. The same is true for future SLR-related
projects.
The City agrees with this finding
conMtent OL 1,
cities.
The City agrees with this finding with regards to South San Francisco.
F8. There is a recognized need for a countywide approach to S,LR planning
7nd coordination among jurisdictions.
The City agrees with this finding.
F9. Several city managers and others interviewed did not support having
new countywide organization assume direct contro,l of levee projects
ihis time.
The City was not a party to those discussions, so it cannot comment on them,
-34-
FIO. The County and cities can address SLR in their General Plans, and
Climate Action Plans, can map the threat, and can adopt relevant policies.
The City partially disagrees with this finding. As indicated in finding number 5,
the problem of sea level rise crosses political boundaries. While the City agrees
that it imakes sense to address SLR in its General Plan, policies will need to be
coordinated with neighboring agencies to be effective.
F11. Many actions to address SLR are within the authority of regional,
State, and federal agencies.
The City agrees with this finding.
F'12. By acting now, SIVIC may be able to red ' uce future costs by integrating
SLR - related projects with other programmed levee projects, and by using
land use planning measures to mitigate future exposure to SLR.
The City agrees with this finding.
Response to Grand Jury Recommendations:
R1. The County, each city in the county and relevant local special agencies
should conduct a public education effort to increase awareness of SLR and
its potential effects on this county.
The recommendation has not yet been implemented by the City, The City
agrees that more public education is needed. There has to be a consistent
message about sea level rise or education efforts will be dismissed by a
significant number of the community members. Education efforts should be
coordinated on a county or regional level and are contingent upon R2 and R3.
The Grand Jury recommends identifying a single organization to underta
SLR planning: i
-35-
The recommendation has not yet been implemented and cannot be implemented
by the City without the cooperation of other agencies. The City is supportive of
an evaluation of the various governance options to address sea level rise, but
does not control the timing of when the study would be complete, Besides the
options that the Grand Jury mentions above, another possibility is the
City/County Association of Governments (C/CAG).
R3. The organization's responsibilities should include:
• Adopt consistent SLR projections for use in levee planning countywide
• Conduct and/or evaluate vulnerability assessments
• Provide a forum for inter jurisdictional coordinati'din and exchange of
information, related to SLR
a ry
- Undertake grant applications for SLR- related pla'anrithng and projects
• Facilitate raising funds on a countywide basi, '4or SORm"re late d projects, to
be passed through to agencies with direct respon't , foility for project
construction
• Monitor actual SLR over time and any changes in SLR projections, based
upon the latest federal, State, or regional government reports and scientific
studies
• Through the CEQA environmental review process, comment on major new
developments proposed in the SLR floodplain,
• Advocate on behalf of the m I )q mb'er-Ju'risdictions with federal, State, and
regional agencies regarding SI-R,,"issues,
• Assist the County and cities in public awareness efforts, as described in
RI
The recommendation has not yet been implemented and cannot be implemented
by the City without the cooperation of other agencies. The City is supportive of
an evaluation of the various governance options to address sea level rise, but
does not control the timing of when the study would be complete.
R• . The County, cities and two relevant local special agencies should
cons,ider expanding the role of the organization beyond SLR to include
planning and coordination • efforts to address existing flooding problems
21ong the Bay, coast, and creeks that are subject to tidal action., It may be
cost-effective to integrate SLR protection with other levee-improveiment
programs.
'The County and cities may also consider expanding the role of the new
organiization to include potentially compatible functions such as the
National Pollution Discharge Elimination System (NPDES), currently
managed • C/CAG, and the new (2014) State requirements for local
sustainable groundwater planning.
The recommendation has not yet been implemented and cannot be implemented
by the City without the cooperation of other agencies. The City is supportive of
M.
an evaluation of the various governance options to address sea level rise, but
does not control the timing of when the study would be complete. The City
agrees that these responsibilities should be considered in a countywide entity's
scope.
R5. The organization –its administration, staffing, and program expenses—
should be funded on a sustainable basis by:
• Member contributions
• Contributions solicited from parties threatened by SLR, including
corporations and agencies that operate public facilities, such as wastewater
treatment plants
• Grants solicited from available potential source such as the California
Climate Resilience Account
• Reducing administrative costs by contracting"'11"If r services with the County
or another agency
The recommendation has not yet been implemented and cannot be implemented
by the City without the cooperation of other. agencies. The City is supportive of
an evaluation of the various governance options to address sea level rise, but
does not control the timing of when the study would be complete. Funding
sources should not be limited to those identified. Alternative and new funding
sources should be an addition to the list of funding sources. The City agrees that
a sustainable source of funding and'staffihg","is critical to its success.
The Grand Jury recommends that SLR be addressed in local land use
planning:
R6. The County and each city should amend its General Plan, as needed, to
address the risk for SLR. The Safety Element should include a map of any
areas vulnerable to SLR, as determined by measurements in the
countywide Vulnerability Assessment [R3]. Further, it should identify
policies that apply to areas threatened by SLR.
The City agrees with this concept, but does not believe it can be implemented
within the timeframe allowed by the Grand Jury. Many of the studies to map
vulnerable areas and draw a nexus for mitigation fees will take considerable time.
The studies should be conducted on a regional basis and are tied to R2, R3, R4,
and R5. The City is supportive of an evaluation of the various governance
options to address sea level rise, but does not control the timing of when the
study would be complete.
The Grand Jury recommends that local governments champion SLR issu
before regional, State, and federal governments and agencies: i
• �County, cities, and relevant local special agencies, through their
representatives on regional agencies, membership in state associations,
-37-
lobbyists, and elected State and federal legislators, should pursue SLR-
related issues with government bodies outside SIVIC.
The City has implemented the recommendation through involvement on the Bay
Conservation and Development Commission Board of Directors as well as
involvement of staff on previous sea level rise studies. The City will continue in
these efforts.
The City of South San Francisco appreciates the opportunity to respond to the
Grand Jury report. The City will continue in the regional effort to address the
effects of sea level rise.
Sincerely,
Richard A. Garbarino,
Mayor.
