5 MITIGATION STRATEGY

Sacramento County 5.1 Local Hazard Mitigation Plan Update September 2011

Requirement §201.6(c)(3): [The plan shall include] a mitigation strategy that provides the

jurisdiction’s blueprint for reducing the potential losses identified in the risk assessment,

based on existing authorities, policies, programs and resources, and its ability to expand on

and improve these existing tools.

This section describes the mitigation strategy process and mitigation action plan for the

Sacramento County Local Hazard Mitigation Plan. It describes how the County and

participating jurisdictions met the following requirements from the 10-step planning process:

Planning Step 6: Set Goals

Planning Step 7: Review Possible Activities

Planning Step 8: Draft an Action Plan

5.1 Mitigation Strategy: Overview

The results of the planning process, the risk assessment, the goal setting, the identification of

mitigation actions, and the hard work of the HMPC led to the mitigation strategy and mitigation

action plan for this LHMP update. As part of the plan update process, a comprehensive review

and update of the mitigation strategy portion of the plan was conducted by the HMPC. Some of

the initial goals and objectives from the 2005 plan were refined and reaffirmed, some goals were

deleted, and others were added. The end result was a new set of goals, reorganized to reflect the

completion of 2005 actions, the updated risk assessment and the new priorities of this plan

update. To support the new LHMP goals, the mitigation actions from 2005 were reviewed and

assessed for their value in reducing risk and vulnerability to the planning area from identified

hazards and evaluated for their inclusion in this plan update (See Section 2.0 What’s New).

Section 5.2 below identifies the new goals and objectives of this plan update and Section 5.4

details the new mitigation action plan.

Taking all of the above into consideration, the HMPC developed the following umbrella

mitigation strategy for this LHMP update:

Communicate the hazard information collected and analyzed through this planning process as

well as HMPC success stories so that the community better understands what can happen

where and what they themselves can do to be better prepared.

Implement the action plan recommendations of this plan.

Use existing rules, regulations, policies, and procedures already in existence.

Monitor multi-objective management opportunities so that funding opportunities may be

shared and packaged and broader constituent support may be garnered.

Sacramento County 5.2 Local Hazard Mitigation Plan Update September 2011

5.1.1 Continued Compliance with NFIP

Given the flood hazard in the planning area, an emphasis will be placed on continued compliance

with the National Flood Insurance Program (NFIP) and participation by Sacramento County and

the City of Sacramento in the Community Rating System. Other cities are encouraged to begin

participating in the CRS. Detailed below is a description of the County’s flood management

program to ensure continued compliance with the NFIP. Also to be considered are the numerous

flood mitigation actions contained in this LHMP that support the ongoing efforts by the county

to minimize the risk and vulnerability of the community to the flood hazard and to enhance their

overall floodplain management program.

Sacramento County’s Flood Management Program

Sacramento County has participated in the Regular Phase1 of the NFIP since 1979. Since then,

the County has administered floodplain management regulations that meet the minimum

requirements of the NFIP. Under that arrangement, residents and businesses paid the same flood

insurance premium rates as most other communities in the country.

Sacramento County has participated in CRS since 1992, shortly after its 1990 launch. The CRS

program is designed to recognize floodplain management activities that go above and beyond the

NFIP’s minimum requirements. CRS is designed to reward a community for implementing

public information, mapping, regulatory, loss reduction and/or flood preparedness activities. On

a scale of 10 to 1, Sacramento County is currently ranked Class 4 putting it in the top eleven in

the nation and second best in California.

The activities credited by the CRS provide direct benefits to Sacramento County and its

residents, including:

Enhanced public safety;

A reduction in damage to property and public infrastructure;

Avoidance of economic disruption and losses;

Reduction of human suffering; and

Protection of the environment.

The activities that Sacramento County implements and receives CRS credits for include:

Activity 310 – Elevation Certificates: The Water Resources Department maintains

elevation certificates for new and substantially improved buildings. Copies of elevation

1 There are two phases for a community’s participation in the NFIP. The Emergency Program is the initial phase of

a community’s participation in the NFIP. Limited amounts of insurance coverage are provided. The Regular

Program is the final phase of a community’s participation in the NFIP. In this phase, a FIRM is in effect and full

limits of coverage are available.

Page 3: 5.1 Mitigation Strategy: Overview · with the National Flood Insurance Program (NFIP) and participation by Sacramento County and the City of Sacramento in the Community Rating System

Sacramento County 5.3 Local Hazard Mitigation Plan Update September 2011

certificates are made available upon request. Elevation Certificates are also kept for post-

FIRM and pre-FIRM buildings and maintained in computer format. Elevation Certificates,

plans, regulations and other records are maintained in a secure location away from the permit

office.

Activity 320 – Map Information Service: Credit is provided for furnishing inquirers with

flood zone information from the community's latest Flood Insurance Rate Map (FIRM),

publicizing the service annually and maintaining records.

Activity 330 – Outreach Projects: A community brochure is mailed to all properties in the

community on an annual basis. An outreach brochure is mailed annually to all properties in

the community's Special Flood Hazard Area (SFHA). The community also provides flood

information through displays at public buildings and community events.

Activity 340 – Hazard Disclosure: Credit is provided for state and community regulations

requiring disclosure of flood hazards.

Activity 350 – Flood Protection Information: Documents relating to floodplain

management are available in the reference section of the Sacramento Public Library. Credit

is also provided for floodplain information displayed on the community's website.

Activity 360 – Flood Protection Assistance: The community provides technical advice and

assistance to interested property owners and annually publicizes the service.

Activity 410 – Additional Flood Data: Credit is provided for conducting and adopting

flood studies for areas not included on the flood insurance rate maps and that exceed

minimum mapping standards. Credit is also provided for a cooperating technical partnership

agreement with FEMA.

Activity 420 – Open Space Preservation: Credit is provided for preserving approximately

5 acres in the Special Flood Hazard Area (SFHA) as open space. Credit is also provided for

open space land that is deed restricted.

Activity 430 – Higher Regulatory Standards: Credit is provided for enforcing regulations

that require freeboard for new and substantial improvement construction, protection of

floodplain storage capacity, natural and beneficial functions, enclosure limits, other higher

regulatory standards, land development criteria and state mandated regulatory standards.

Credit is also provided for a Building Code Effectiveness Grading Schedule (BCEGS)

Classification of 3/3, for certification as a floodplain manager and the adoption of the

International Building Codes.

Activity 440 – Flood Data Maintenance: Credit is provided for maintaining and using

digitized maps in the day to day management of the floodplain. Credit is also provided for

maintaining copies of all previous FIRMs and Flood Insurance Study Reports.

Activity 450 – Stormwater Management: The community enforces regulations for

stormwater management, freeboard in non-SFHA zones, soil and erosion control, and water

quality. Credit is also provided for watershed management master planning.

Activity 510 – Floodplain Management Planning: Based on the updates made to the NFIP

Report of Repetitive Losses as of June 30, 2008, Sacramento County has 102 repetitive loss

properties and is a Category C community for CRS purposes. All requirements for the 2009

cycle have been met. The County continuously tracks repetitive loss properties, and the

Page 4: 5.1 Mitigation Strategy: Overview · with the National Flood Insurance Program (NFIP) and participation by Sacramento County and the City of Sacramento in the Community Rating System

Sacramento County 5.4 Local Hazard Mitigation Plan Update September 2011

current repetitive loss status of the County is included in Appendix H to this plan. Credit is

provided for the adoption and implementation of the Floodplain Management Plan. Since

Sacramento County is a Category C2 community with an approved Floodplain Management

Plan, a progress report must be submitted on an annual basis. In addition, as detailed in the

Section 3.0, Planning Process, this LHMP is being developed to maximize CRS credits for

Activity 510.

Activity 520 – Acquisition and Relocation: Credit is provided for acquiring and relocating

buildings from the community's flood hazard area.

Activity 530 – Flood Protection: Credit is provided for buildings that have been flood

proofed, elevated or otherwise modified to protect them from flood damage.

Activity 540 – Drainage System Maintenance: Portions of the community's drainage

system are inspected regularly throughout the year and maintenance is performed as needed

by the Department of Water Resources. Records are being maintained for both inspections

and required maintenance. Credit is also provided for an ongoing Capital Improvements

Program. The community also enforces a regulation prohibiting dumping in the drainage

system.

Activity 610 – Flood Warning Program: Credit is provided for a program that provides

timely identification of impending flood threats, disseminates warnings to appropriate

floodplain residents, and coordinates flood response activities.

Activity 630 – Dam Safety: All California communities currently receive CRS credit for the

state's dam safety program.

The 300-series CRS activities are continued as a regular part of the County’s floodplain

management program. In addition, Activity 330 in the 2012 manual prompted Sacramento

County to collaborate with the City of Sacramento to participate as pilot communities to assist in

developing and testing proposed revisions to the 2012 CRS public information program.

The 2012 CRS Public Information Series is being revised to credit CRS communities for

developing programs for public information specifically tailored to their particular hazards,

natural resources, and audiences. Such a program would be like an existing public information

strategy but using more creative approaches to communicate with target audiences. The revision

will also include measurement techniques to assess outcomes and redirect programs as needed to

achieve desired outcomes.

2 The CRS classifies communities into three categories. Each category of community must deal with repetitive flood

problems in different ways, depending on the severity of the repetitive-loss problem. Class A: A community with

no unmitigated repetitive loss properties. No special requirements from the CRS. Class B: A community with at

least one, but fewer than 10, unmitigated repetitive loss properties. Class B communities are required by the CRS to

research and describe their repetitive loss problem, create a map showing the location of all repetitive loss properties

and complete an annual outreach activity directed to the repetitive loss addresses. Class C: A community with 10 or

more unmitigated repetitive loss properties. The CRS requires Class C communities to do everything a Class B

community does as well as prepare a floodplain management plan and repetitive loss area analysis for all areas.

Sacramento County 5.5 Local Hazard Mitigation Plan Update September 2011

The pilot program includes establishing a committee to include non-government stakeholders

who are involved in flood concerns or flood-related public information activities.

The CRS identified six messages of primary importance to the program. The committee will

evaluate each of six messages for applicability to the local situation, and develop public

information projects for each relevant message. The CRS public information program will be

implemented over a strategic time phase. More information on this pilot program is provided in

Mitigation Action #2 of this LHMP.

Additional work in the 400-series – The County is mapping local flood hazards, to be posted on a

web-based system (activity 410) in an effort to provide the public with flood hazard information

in addition to the FEMA flood insurance rate maps. The (activity 450) watershed management

plan, a section herein, will be kept current collaborating with the cooperative technical partner

cities and the county.

Additional work in the 500-series - The County will continue to work with repetitive loss

property owners to mitigate future loss potential reporting on an annual basis. Additionally,

there are two homes scheduled to be elevated subject to grant application currently in the queue.

Meanwhile the drainage maintenance team is maintaining GIS based call logs and prioritizing

drainage improvement projects.

Additional work in the 600-series - a committee will consider how public outreach might better

describe various flood hazards.

5.2 Goals and Objectives

Requirement §201.6(c)(3)(i): [The hazard mitigation strategy shall include a] description of

mitigation goals to reduce or avoid long-term vulnerabilities to the identified hazards.

Up to this point in the planning process, the HMPC has organized resources, assessed hazards

and risks, and documented mitigation capabilities. The resulting goals, objectives, and

mitigation actions were developed based on these tasks. The HMPC held a series of meetings

and exercises designed to achieve a collaborative mitigation strategy as described further

throughout this section.

During the initial goal-setting meeting, the HMPC reviewed the results of the hazard

identification, vulnerability assessment, and capability assessment. This analysis of the risk

assessment identified areas where improvements could be made and provided the framework for

the HMPC to formulate planning goals and objectives and to develop the mitigation strategy for

the Sacramento County Planning Area.

Goals were defined for the purpose of this mitigation plan as broad-based public policy

statements that:

Page 6: 5.1 Mitigation Strategy: Overview · with the National Flood Insurance Program (NFIP) and participation by Sacramento County and the City of Sacramento in the Community Rating System

Sacramento County 5.6 Local Hazard Mitigation Plan Update September 2011

Represent basic desires of the community;

Encompass all aspects of community, public and private;

Are nonspecific, in that they refer to the quality (not the quantity) of the outcome;

Are future-oriented, in that they are achievable in the future; and

Are time-independent, in that they are not scheduled events.

Goals are stated without regard to implementation. Implementation cost, schedule, and means

are not considered. Goals are defined before considering how to accomplish them so that they

are not dependent on the means of achievement. Goal statements form the basis for objectives

and actions that will be used as means to achieve the goals. Objectives define strategies to attain

the goals and are more specific and measurable.

HMPC members were provided with the list of goals from the 2005 plan as well as a list of other

sample goals to consider. They were told that they could use, combine, or revise the statements

provided or develop new ones, keeping the risk assessment in mind. Each member was given

three index cards and asked to write a goal statement on each. Goal statements were collected

and grouped into similar themes and displayed on the wall of the meeting room. The goal

statements were then grouped into similar topics. New goals from the HMPC were discussed

until the team came to consensus. Some of the statements were determined to be better suited as

objectives or actual mitigation actions and were set aside for later use. Next, the HMPC

developed objectives that summarized strategies to achieve each goal.

Based on the risk assessment review and goal setting process, the HMPC identified the following

goals and objectives, which provide the direction for reducing future hazard-related losses within

the Sacramento County Planning Area.

GOAL 1: Minimize the loss of life, injury, and property damage from natural hazards

timelines, and processes

5.3 Identification and Analysis of Mitigation Actions

Requirement §201.6(c)(3)(ii): [The mitigation strategy shall include a] section that

identifies and analyzes a comprehensive range of specific mitigation actions and projects

being considered to reduce the effects of each hazard, with particular emphasis on new and

existing buildings and infrastructure.

In order to identify and select mitigation actions to support the mitigation goals, each hazard

identified in Section 4.1 Identifying Hazards: Natural Hazards was evaluated. Only those

hazards that were determined to be a priority hazard were considered further in the development

of hazard-specific mitigation actions.

These priority hazards (in alphabetical order) are:

Bird Strike

Dam Failure

Drought

Earthquake

Earthquake Liquefaction

Flood: 100/200/500–year

Flood: Localized/Stormwater

Levee Failure

River/Stream/Creek Bank Erosion

Severe Weather: Heavy Rains and Storms

Subsidence

Wildfire

The HMPC eliminated the hazards identified below from further consideration in the

development of mitigation actions because the risk of a hazard event in the County is unlikely or

nonexistent, the vulnerability of the County is low, or capabilities are already in place to mitigate

negative impacts. The eliminated hazards are:

Page 9: 5.1 Mitigation Strategy: Overview · with the National Flood Insurance Program (NFIP) and participation by Sacramento County and the City of Sacramento in the Community Rating System

Sacramento County 5.9 Local Hazard Mitigation Plan Update September 2011

Ag Hazards: Insect Pest

Landslide

Severe Weather: Extreme Heat

Severe Weather: Fog

Severe Weather: Freeze

Severe Weather: Tornadoes

Volcano

It is important to note, however, that all the hazards addressed in this plan are included in the

countywide multi-hazard public awareness mitigation action as well as in other multi-hazard,

emergency management actions.

Once it was determined which hazards warranted the development of specific mitigation actions,

the HMPC analyzed viable mitigation options that supported the identified goals and objectives.

The HMPC was provided with the following list of categories of mitigation actions, which

originate from the Community Rating System:

Prevention

Property protection

Structural projects

Natural resource protection

Emergency services

Public information

The HMPC was also provided with examples of potential mitigation action alternatives for each

of the above categories. The HMPC was also instructed to consider both future and existing

buildings in considering possible mitigation actions. A facilitated discussion then took place to

examine and analyze the options. Appendix C, Mitigation Strategy, provides a detailed

discussion by CRS mitigation category to assist in the review and identification of possible

mitigation activities. Also utilized in the review of possible mitigation measures is FEMA’s

publication on Mitigation Ideas, by hazard type. This was followed by a brainstorming session

that generated a list of preferred mitigation actions by hazard.

5.3.1 Prioritization Process

Once the mitigation actions were identified, the HMPC was provided with several decision-

making tools, including FEMA’s recommended prioritization criteria, STAPLEE sustainable

disaster recovery criteria; Smart Growth principles; and others, to assist in deciding why one

recommended action might be more important, more effective, or more likely to be implemented

than another. STAPLEE stands for the following:

Social: Does the measure treat people fairly? (e.g., different groups, different generations)

Technical: Is the action technically feasible? Does it solve the problem?

Page 10: 5.1 Mitigation Strategy: Overview · with the National Flood Insurance Program (NFIP) and participation by Sacramento County and the City of Sacramento in the Community Rating System

Sacramento County 5.10 Local Hazard Mitigation Plan Update September 2011

Administrative: Are there adequate staffing, funding, and other capabilities to implement the

project?

Political: Who are the stakeholders? Will there be adequate political and public support for

the project?

Legal: Does the jurisdiction have the legal authority to implement the action? Is it legal?

Economic: Is the action cost-beneficial? Is there funding available? Will the action

contribute to the local economy?

Environmental: Does the action comply with environmental regulations? Will there be

negative environmental consequences from the action?

In accordance with the DMA requirements, an emphasis was placed on the importance of a

benefit-cost analysis in determining action priority. Other criteria used to assist in evaluating the

benefit-cost of a mitigation action includes:

Does the action address hazards or areas with the highest risk?

Does the action protect lives?

Does the action protect infrastructure, community assets or critical facilities?

Does the action meet multiple objectives (Multiple Objective Management)?

What will the action cost?

What is the timing of available funding?

The mitigation categories, multi-hazard actions, and criteria are included in Appendix C:

Mitigation Categories, Alternatives, and Selection Criteria.

With these criteria in mind, HMPC members were each given a set of eighteen colored dots, six

each of red, blue, and yellow. The dots were assigned red for high priority (worth five points),

blue for medium priority (worth three points), and yellow for low priority (worth one point). The

team was asked to use the dots to prioritize actions with the above criteria in mind. The point

score for each action was totaled. Appendix C contains the total score given to each identified

mitigation action.

The process of identification and analysis of mitigation alternatives allowed the HMPC to come

to consensus and to prioritize recommended mitigation actions. During the voting process,

emphasis was placed on the importance of a benefit-cost review in determining project priority;

however, this was not a quantitative analysis. After completing the prioritization exercise, some

team members expressed concern that prioritizing all the actions as a group is not very effective,

since many of the actions are jurisdiction- or department-specific. However, the team agreed

that prioritizing the actions collectively enabled the actions to be ranked in order of relative

importance and helped steer the development of additional actions that meet the more important

objectives while eliminating some of the actions which did not garner much support.

Benefit-cost was also considered in greater detail in the development of the Mitigation Action

Plan detailed below in Section 5.3. Specifically, each action developed for this plan contains a

Page 11: 5.1 Mitigation Strategy: Overview · with the National Flood Insurance Program (NFIP) and participation by Sacramento County and the City of Sacramento in the Community Rating System

Sacramento County 5.11 Local Hazard Mitigation Plan Update September 2011

description of the problem and proposed project, the entity with primary responsibility for

implementation, any other alternatives considered, a cost estimate, expected project benefits,

potential funding sources, and a schedule for implementation. Development of these project

details for each action led to the determination of a High, Medium, or Low priority for each.

Recognizing the limitations in prioritizing actions from multiple jurisdictions and departments

and the regulatory requirement to prioritize by benefit-cost to ensure cost-effectiveness, the

HMPC decided to pursue:

mitigation action strategy development and implementation according to the nature and

extent of damages;

the level of protection and benefits each action provides;

political support;

project cost;

available funding; and

individual jurisdiction and department priority.

This process drove the development of a prioritized action plan for the Sacramento County

Planning Area. Cost-effectiveness will be considered in greater detail through performing

benefit-cost project analyses when seeking FEMA mitigation grant funding for eligible actions

associated with this plan.

5.4 Mitigation Action Plan

Requirement §201.6(c)(3)(iii): [The mitigation strategy section shall include] an action plan

describing how the actions identified in section (c)(3)(ii) will be prioritized, implemented,

and administered by the local jurisdiction. Prioritization shall include a special emphasis

on the extent to which benefits are maximized according to a cost benefit review of the

proposed projects and their associated costs.

This action plan was developed to present the recommendations developed by the HMPC for

how the Sacramento County Planning Area can reduce the risk and vulnerability of people,

property, infrastructure, and natural and cultural resources to future disaster losses. Emphasis

was placed on both future and existing development. The action plan summarizes who is

responsible for implementing each of the prioritized actions as well as when and how the actions

will be implemented. Each action summary also includes a discussion of the benefit-cost review

conducted to meet the regulatory requirements of the Disaster Mitigation Act. Table 5.1

identifies the mitigation actions and lead jurisdiction for each action. Only those actions where

the County is the lead jurisdiction are detailed further in this section. Actions specific to other

participating jurisdictions, or where other jurisdictions are taking the lead, are detailed in each

respective jurisdictional annex to this plan.

Page 12: 5.1 Mitigation Strategy: Overview · with the National Flood Insurance Program (NFIP) and participation by Sacramento County and the City of Sacramento in the Community Rating System

Sacramento County 5.12 Local Hazard Mitigation Plan Update September 2011

The action plan detailed below contains both new action items developed for this plan update as

well as old actions that were yet to be completed from the 2005 plan. Table 5.1 indicates

whether the action is new or from the 2005 plan and Section 2.0 contains the details for each

2005 mitigation action item indicating whether a given action item has been completed, deleted,

or deferred.

It is important to note that Sacramento County and the participating jurisdictions have numerous

existing, detailed action descriptions, which include benefit-cost estimates, in other planning

documents, such as watershed plans, stormwater plans, community wildfire protection plans, and

capital improvement budgets and reports. These actions are considered to be part of this plan,

and the details, to avoid duplication, should be referenced in their original source document. The

HMPC also realizes that new needs and priorities may arise as a result of a disaster or other

circumstances and reserves the right to support new actions, as necessary, as long as they

conform to the overall goals of this plan.

Further, it should be clarified that the actions included in this mitigation strategy are subject to

further review and refinement; alternatives analyses; and reprioritization due to funding

availability and/or other criteria. The participating communities are not obligated by this

document to implement any or all of these projects. Rather this mitigation strategy represents the

desires of the community to mitigate the risks and vulnerabilities from identified hazards. The

actual selection, prioritization, and implementation of these actions will also be further evaluated

in accordance with the CRS mitigation categories and criteria contained in Appendix C.

Also, many of the action items included in this plan are a collaborative effort among

participating jurisdictions and other local, state, and federal agencies and stakeholders in the

Sacramento County planning area. Table 5.1 identifies the lead jurisdiction. The individual

worksheets for each mitigation action item identify other mitigation partners. In addition, many

of the more regional actions where the county or other jurisdictions are identified as the lead,

such as the Enhance Public Awareness of the Affects of Natural Hazards and Public

Understanding of Disaster Preparedness, will provide a mitigation benefit to all participating

jurisdictions.

Issue/Background: There are a total of 17 jurisdictions participating in the Sacramento-area

Local Hazard Mitigation Plan. Each jurisdiction is responsible for their own outreach/education

program for hazards in their community. The level of effort varies by jurisdiction. All

jurisdictions contend with limited resources; some must sacrifice educational outreach

campaigns to direct their limited resources to the most critical projects. A single unified outreach

program will ascertain both broad and targeted educational needs. Resources will be leveraged

by consolidating messaging where appropriate and reaching across jurisdictional lines.

Other Alternatives: Status quo.

Existing Planning Mechanism(s) through which Action Will Be Implemented: Existing

outreach programs will be reviewed for effectiveness. Successful components will be expanded

across the broader region.

Benefits (Losses Avoided): Increase residents’ knowledge of potential hazards and activities

required to mitigate hazards.

Potential Funding: HMGP Grant

Schedule: 2012/13

2. CRS Public Information Pilot Program

Hazards Addressed: Flood, Dam Failure, Levee Failure

Issue/Background: The 2012 CRS Public Information Series is being revised to credit CRS

three types of Outreach Projects: 1.) Program for Public Information; 2.) Stakeholder

Implementation; and, 3.) Action Resulting from Outreach.

The County of Sacramento is a pilot community, in partnership with the City of Sacramento, to

―field test‖ the expanded CRS outreach opportunities and will develop recommendations for the

CRS Program Directors’ consideration as they finalize the 2012 CRS Program modifications.

The pilot program involves establishing a committee to include non-government stakeholders

who are involved in flood concerns or flood-related public information activities. In addition to

government participants, the PPI committee members include a representative from the flood

insurance community, a non-profit dedicated to community safety and security, and

representatives from local broadcast media. The committee also includes county and city elected

officials or members of their immediate staffs.

Program for Public Information

The CRS identified six messages of primary importance to the program. The PPI allows up to

four addition messages of local targeted interest. The committee will evaluate each of the

messages for applicability to the regional situation, and develop public information projects for

each relevant message.

For each message, the committee will:

Identify target areas and target audiences

Conduct effectiveness assessments of current public information programs

Identify similar public information efforts from other department programs or other regional

agencies

Page 29: 5.1 Mitigation Strategy: Overview · with the National Flood Insurance Program (NFIP) and participation by Sacramento County and the City of Sacramento in the Community Rating System

Sacramento County 5.29 Local Hazard Mitigation Plan Update September 2011

Develop desired outcomes for each message, i.e.: financially protect homeowners from flood

losses

Develop an public information strategy/project for each desired outcome

Establish measurement criteria for each project

Conduct an annual evaluation of the effectiveness of each project with respect to its outreach

goal.

Outreach projects the commit will consider for each message can include:

Informational Materials,

Traditional Media: Television, Radio, Newspaper

Outdoor advertising: Billboard, Transit, Signage

Presentations to organizations, such as homeowners, civic and business associations

Classroom Presentations

Social Media: Twitter, Facebook

Stakeholder Implementation

Projects components will be developed for stakeholders to manage. The PPI committee will

monitor the progress of stakeholder implemented projects and conduct an annual effectiveness

evaluation.

Action Resulting from Outreach

Annually, the committee will review each project to determin the project’s effectiveness in

reaching the outreach goal. Projects that are not achieving the goal will be modified or dropped

in favor of a project that is more likely to achieve a given outreach goal.

Other Alternatives: Continue with existing public information program for CRS

Existing Planning Mechanism(s) through which Action Will Be Implemented: CRS program

Schedule: 2011 - ongoing

3. Integrate Local Hazard Mitigation Plan into Safety Element of General Plan

Hazards Addressed: All

Issue/Background: Local jurisdiction reimbursement for mitigation projects and cost recovery

after a disaster is guided by Government Code Section 8685.9. Specifically, this section requires

that the County must adopt a local hazard mitigation plan (LHMP) in accordance with the federal

Disaster Mitigation Act of 2000 as part of the safety element of its general plan adopted pursuant

to subdivision (g) of Section 65302. It is important for Sacramento County to incorporate the

County’s LHMP into the safety element as part of the next general plan update.

Other Alternatives: No feasible alternatives

Existing Planning Mechanisms through which Action will be Implemented:

Responsible Office: Department of Water Resources

Priority (High, Medium, Low): High

Cost Estimate: $8,000-10,000 application fees

Potential Funding: State and/or Federal Grant

Benefits (avoided Losses): Planning documents will help the City maximize potential for state

reimbursement

Schedule: As soon as possible

4. Flood Insurance Promotion

Hazards Addressed: Flood, Dam Failure, Levee Failure

Issue/Background: This new CRS activity credits communities that take an active role in

encouraging residents and businesses to purchase and maintain adequate flood insurance

coverage. It credits a four-step process that allows communities to assess their own needs and

receive credit for improving their coverage.

Assessment of flood insurance coverage: Perform the CRS self-assessment and conduct a review

of existing flood insurance policies, by type for the total community and by specific community

flood hazard areas.

Page 31: 5.1 Mitigation Strategy: Overview · with the National Flood Insurance Program (NFIP) and participation by Sacramento County and the City of Sacramento in the Community Rating System

Sacramento County 5.31 Local Hazard Mitigation Plan Update September 2011

Flood Insurance Outreach Plan: Design an outreach plan to educate the community, by

demographic target, of the importance of having flood insurance protection. The Flood Insurance

Promotion Plan will be reviewed and approved by the Program for Public Information (PPI)

committee.

Outreach Plan Implementation: Implement the various components of the outreach plan.

Coverage Improvement: Conduct an annual review of the effectiveness of the outreach plan. A

likely measurement of success would be an increase in flood insurance policies.

Other Alternatives: Continue with existing public information program for flood insurance.

Existing Planning Mechanism(s) through which Action Will Be Implemented: CRS program

Responsible Office: DWR Drainage Development section and Communications and Media

Office

Priority (H, M, L): High

Cost Estimate: $20,000 annually

Benefits (Losses Avoided): Life Safety, Property Protection

Potential Funding: HMGP Grant

Schedule: 2011 – ongoing

5. Evaluation and Mitigation of Critical Facilities in Identified Hazard Areas

Hazards Addressed: Flood, Dam Inundation, Levee Failure, Wildfire

Issue/Background: Based on the critical facility analysis completed for this plan, over 3,000

critical facilities have been identified within the Sacramento County Planning Area. This

number is anticipated to go up based on additional mapping of critical facilities as the GIS

mapping effort is completed. For Sacramento County, 52 mapped critical facilities have been

identified within the 100 year floodplain and another 164 (81-city) in the 500-year floodplain. A

detailed list of those affected critical facilities are included in Appendix E. Due to the significant

number of critical facilities identified within the flood and other hazard areas, additional

evaluation of each affected facility is required in order to determine which facilities should be

potentially relocated and/or protected. This project addresses the additional evaluation of

identified critical facilities to determine options for mitigation. The initial focus will be on those

facilities within the flood hazard areas, with other hazard-prone facilities to follow. The end

result of this analysis will be a list of facilities within the 100- and 500-year floodplain and their

mitigation recommendations and priorities.

Page 32: 5.1 Mitigation Strategy: Overview · with the National Flood Insurance Program (NFIP) and participation by Sacramento County and the City of Sacramento in the Community Rating System

Sacramento County 5.32 Local Hazard Mitigation Plan Update September 2011

Other Alternatives: No action, remove all critical facilities from the floodplain.

Existing Planning Mechanism(s) through which Action Will Be Implemented: This will be

implemented through the County floodplain management program

Responsible Office: County DWR

Cost Estimate: Analysis and recommendations should involve staff time; resulting mitigation

measures will be cost on an individual facility basis.

Priority (H, M, L): High

Benefits (Losses Avoided): Analyzing mitigation measures for critical facilities will increase

both property protection and life safety for County residents.

Potential Funding: Existing budgets.

Schedule: Within five years

6. Finalize and Implement the Actions of the South Sacrament Habitat Conservation

Plan (SSHCP)

Hazards Addressed: Flood, wildfire, severe storms

Issue/Background: The South Sacramento Habitat Conservation Plan (SSHCP or Plan)

provides a regional approach to balancing development against conservation and protection of

habitat, open space, and agricultural lands. The SSHCP protects 30 species of plants and wildlife

including 10 that are listed as threatened or endangered under either the federal Endangered

Species Act (ESA), the California Endangered Species Act (CESA), or both. The SSHCP also

protects vernal pool, wetland, and stream habitats that are subject to the federal Clean Water Act

(CWA) and California's Porter-Cologne Water Quality Control Act. The SSHCP also seeks a

programmatic Streambed Alteration Agreement under Fish and Game Code Sections 1600, et

seq.

The primary mechanism for conservation established under the Plan is the SSHCP Reserve

System, which will conserve habitat that will be managed and monitored to achieve the

biological goals and objectives for the covered species. Draft objectives are listed below.

Landscape Objective 1.1: Establish a 41,923-acre Reserve System that provides habitat for

covered species and other native biota.

Landscape Objective 2.1: Restore and/or create 1,786 acres of habitat within the Reserve

System to support covered species.

Landscape Objective 3.1: Ensure that preserves are designed to capture some portion of each

habitat type and establish preserves across different environmental gradients.

Page 33: 5.1 Mitigation Strategy: Overview · with the National Flood Insurance Program (NFIP) and participation by Sacramento County and the City of Sacramento in the Community Rating System

Sacramento County 5.33 Local Hazard Mitigation Plan Update September 2011

Landscape Objective 4.1: Implement best management practices (BMPs), low impact

developments (LIDs), and other avoidance and minimization measures as outlined in Chapter

6 and Appendices N and O. Employ the standards of the SSHCP Preserve Design Principles

as described in Appendix R when assembling preserves into the Reserve System.

Landscape Objective 5.1: Establish an average 50-foot buffer for covered activities at the

perimeter of each preserve within the UDA.

Landscape Objective 6.1: Establish linkages that connect preserves.

Landscape Objective 7.1: Management plans for each preserve will be developed within 1

year of acquisition.

Landscape Objective 7.2: Preserve documentation reports will be prepared for each preserve

prior to acquisition.

Landscape Objective 7.3: Create invasive species control plans for each vernal pool preserve.

Other Alternatives: Do not implement the objectives proposed in the plan and continue the

disjointed, confusing, and ineffective current process.

Existing Planning Mechanism(s) through which Action Will Be Implemented: The Plan

itself is the mechanism through which this action will be implemented.

Responsible Office: Sacramento County, City of Elk Grove, City of Galt, City of Rancho

Cordova, Sacramento Regional County Sanitation District, Sacramento County Water Agency,

Southeastern Connector

Cost Estimate: Since the plan is still in draft stages, cost estimates are still to be determined.

Priority (H, M, L): High

Benefits (Losses Avoided): Currently, individual project proponents must work with the

Wildlife Agencies to obtain permits required by wetland and species laws and regulations. The

resulting process can be disjointed, confusing, and potentially contradictory and ineffective.

Years of negotiation can result in not only costly expenses, lost time, and conflicting regulatory

requirements, but also small, fragmented, and isolated habitats that are difficult to manage

efficiently and typically not conducive to long-term species protection. The SSHCP will change

the existing regulatory regime, which will offer numerous benefits. First, the SSHCP will

provide Sacramento County residents with a comprehensive Reserve System that promotes

healthy, balanced communities, preserves floodplains, buffers agricultural/urban interfaces,

increases recreational opportunities, and protects biological resources and open space for future

generations.

Potential Funding: To be determined

Schedule: Since the plan is in draft state, the schedule for each objective is yet to be determined.

Wildfire

Issue/Background: Although the nation has experienced several horrific disasters during the

past ten years, research shows that individuals and families are still not sufficiently prepared for

disasters. Even the most optimistic reports have found a little more than half of individuals and

families nationally have made any substantive preparations for disasters, and many of these

precautions would prove to be inadequate in the event of a real disaster. Research further

indicates that the situation is no better for individuals with disabilities or other access and

functional needs, and this population is particularly vulnerable during disasters.

SAFELY OUT™, a groundbreaking neighbor-helping-neighbor approach to evacuation, was

developed with technical assistance from the American Red Cross Capital Region Chapter, to

help ensure that our most vulnerable citizens -- including people with disabilities, frail seniors,

young children and others with access and functional needs -- are protected during disasters.

Utilizing neighbors who agree - prior to a disaster - to assist their vulnerable neighbors was

clearly seen as a straightforward, cost effective approach to help accomplish the goal of getting

all of our citizens to safety. Recognizing that we all need to be "first responders" after a disaster,

the SAFELY OUT™ Kit represents a unique alert and helper system, so that a vulnerable person

knows at least three of his or her neighbors have agreed that they will assist them to safety.

SAFELY OUT™ Kits are the foundation of the project. The SAFELY OUT™ Kit consists of a

two-sided door hanger indicating if someone needs help or is ―safely out,‖ a refrigerator magnet

and wallet card for recording essential evacuation and contact information, and information

sheets including a simple how-to-guide and helper details. The kit also contains an erasable pen

for use on the refrigerator magnet, a permanent marker for the door hanger, and adhesive strips

for securing the door hanger to another surface, if necessary. A storage bag which can be placed

in a refrigerator, cabinet, or closet, is included as part of the kit for storing medications and

additional critical medical or insurance information.

Sacramento County 5.35 Local Hazard Mitigation Plan Update September 2011

The completeness of the SAFELY OUT™ approach is what really sets it apart. SAFELY OUT™

is alone in providing a comprehensive kit and program that includes public education, media

outreach, and partnership and sponsorship development. Another unique aspect of the program is

that SAFELY OUT™ Kits are assembled by PRIDE Industries, which delivers first-rate

manufacturing and service solutions to businesses and government agencies nationwide, while

creating meaningful jobs for people with disabilities. The significant benefit of the SAFELY

OUT™ Project approach was recently recognized as a best practice by the RAND Corporation in

its Enhancing Public Health Emergency Preparedness for Special Needs Populations: A Tool kit

for State and Local Planning and Response, based on criteria including overall effectiveness,

comprehensiveness, and ease of implementation.

SAFELY OUT™ has been embraced by emergency responders, leading officials, and

organizations representing the vulnerable—frail seniors, people with disabilities, families with

young children, and more. The SAFELY OUT™ Kit provides a simple, affordable, and very

cost effective and complete solution to evacuation preparedness. The SAFELY OUT™ Project

approach yields an immediate ―street-level‖ impact, by providing the most vulnerable with a

tangible tool to assist them in becoming more prepared. The project exemplifies an almost

unprecedented level of public-private partnership, by bringing together state and local

government agencies, the business community, philanthropic groups, and community and faith-

based organizations, resulting in the distribution of more than 75,000 kits, including more than

50,000 kits in the Sacramento Area.

The SAFELY OUT™ kit is not intended to supplant other preparedness efforts, such as

preparing a comprehensive family preparedness plan, or assembling supplies for sheltering in

place or evacuation. Rather, the SAFELY OUT™ Kit was developed specifically to address

issues having to do with safe evacuation, particularly for those individuals with access and

functional needs. This multi-year, comprehensive HMP project will support the annual

distribution of 5,000 SAFELY OUT™ Kits to the most vulnerable in Sacramento County for

each of the next five years, for a total of 25,000 kits.

Other Alternatives: Some jurisdictions have tried to implement a disaster registry to collect the

names and locations of people who require special assistance, for use by fire and police

personnel, and rescue workers when disaster strikes. This approach has limited effectiveness as

there can be no guarantee that individuals with access and functional needs will get help first

during a disaster, since first responders simply cannot help everyone at once. Further, this

centralized approach shifts the responsibility to the registering agency and to already

overburdened first responders, instead of working with individuals, families, neighbors, and

caretakers to become better prepared and more individually responsible for their own situations

and safety.

While the County certainly should continue to emphasize personal preparedness as part of its

natural hazards public awareness campaign, such campaigns have had limited success in

Page 36: 5.1 Mitigation Strategy: Overview · with the National Flood Insurance Program (NFIP) and participation by Sacramento County and the City of Sacramento in the Community Rating System

Sacramento County 5.36 Local Hazard Mitigation Plan Update September 2011

improving the preparedness of those individuals with access and functional needs, particularly

those with disabilities.

Existing Planning Mechanism(s) through which Action Will Be Implemented: Messaging

supporting SAFELY OUT™ and the preparedness needs of individuals with disabilities and

other access and functional needs should be incorporated into the public awareness campaign

project included in the HMP, as well as evacuation plans developed by the county and other

jurisdictions covered by this plan.

Responsible Office: Sacramento County Department of Water Resources, in partnership with

Citizen Voice, has the lead responsibility for the program. Distribution and outreach efforts will

also be coordinated with additional partner agencies, particularly those directly serving the

vulnerable.

Priority (H, M, L): High

Cost Estimate: $50,000 each year for a five year project period total of $250,000. This will

result in the production and deployment of 5,000 SAFELY OUT™ Kits annually for a total of

25,000 SAFELY OUT™ Kits over the duration of the project.

Benefits (Losses Avoided): This project is designed to save lives by ensuring that the most

vulnerable are evacuated safely, or to enable the quick identification of people requiring

assistance.

Potential Funding: County utility assessment funds

Schedule: Under this project, 5,000 SAFELY OUT™ kits would be distributed annually for five

years.

Bird Strike Mitigation Actions

8. Wildlife Hazard Management Plan

Hazards Addressed: Bird Strike

Issue/Background Statement: The Federal Aviation Administration (FAA) directed that a

year-long Wildlife Hazard Assessment (WHA) be conducted. This is a scientific study to

determine the nature of potential hazardous wildlife attractants on or near the airport. The

Sacramento County Airport System is in the end stages of data collection, which will then be

followed by data analysis. After submittal of the WHA to the FAA, it is anticipate that FAA will

determine that an update is needed to the Sacramento International Airport (SMF) Wildlife

Hazard Management Plan (WHMP). That document, which will probably take another year to

complete, will describe the tools and methods by which hazardous wildlife will be managed at

SMF.

And Rain Gages

Hazards Addressed: Flooding

Issue/Background Statement: The County’s ALERT system has been in operation since 1985.

The collection and dissemination of real time stream and rain data through the Internet provides

County staff, as well as local agencies and the public, with real time rainfall amounts and stream

levels. This information is used to warn of imminent and/or in progress flooding. Archived data

is also used in support of studies on a variety of floodplain and watershed issues. Currently, the

County’s ALERT network is thin within undeveloped portions of the unincorporated area. As

development occurs, there will be a need to augment the ALERT network to provide the public

and emergency responders with timely rain and stream data in these areas. Areas that are

expected to develop within the next 20 years include: Elder Creek, Gerber Creek, Florin Creek,

Unionhouse Creek, Upper Laguna Creek, Upper Morrison Reach, and Deer Creek.

39. Determine Cause and Mitigate Mercury and Methyl Mercury Coming from Tributaries

of American River

Hazards Addressed: Human consumption of sport-fish contaminated with mercury

Issue/Background Statement: As a result of historical releases of mercury associated with gold

mining in Sacramento County, as well as in areas throughout watersheds upstream of

Sacramento County, mercury contamination is a significant hazard to County residents and

visitors, as well as wildlife. The State Resources agency, as well as Cal EPA and US EPA, have

recognized this contamination. The Sacramento-San Joaquin Delta, the American River, Lake

Natomas, and numerous water bodies that are tributary to them, are designated through the Clean

Water Act 303d listing process as impaired water bodies due to mercury levels found in fish that

so high that they are hazardous both to the human population and to wildlife. Additional water

bodies in and near Sacramento are likely to be added to the 303d list in the future due to mercury

contamination. Fish consumption advisories developed by the State Dept. of Public Health and

the Office of Environmental and Health Hazard Assessment warn people not to eat certain types

of fish caught in these waters.

Page 57: 5.1 Mitigation Strategy: Overview · with the National Flood Insurance Program (NFIP) and participation by Sacramento County and the City of Sacramento in the Community Rating System

Sacramento County 5.57 Local Hazard Mitigation Plan Update September 2011

The mitigation of this hazard will address some of the various factors in the Sacramento region

can affect the amount of mercury that enters the food chain and poses a hazard to human health

and the environment. Some of these factors may be subject to some level of influence by human

activity. Monitoring will be necessary to identify and prioritize key factors. Factors that affect

the hazards caused by mercury and may be addressed in the TMDL implementation plan include,

but are not limited to, nutrient levels, sediment transport, streambed modification, food chain and

ecological effects, fish consumption practices, management of water levels, water exports and

diversions, irrigation practices, salinity, oxygen concentrations, wetland restoration and

management practices, flooding of Delta islands, dredging, reservoir management, stormwater

and wastewater discharges and treatment processes, source control and pollution prevention

activities, and levels of mercury in sediments, water bodies, and discharges.

Other Alternatives: No action

Existing Planning Mechanisms through which Action will be Implemented: Delta Mercury

TMDL (adopted by Central Valley RWQCB); American River Mercury TMDL (in process)

Responsible Office: County Dept of Water Resources Stormwater Quality Section

Priority (H, M, L): Medium

40. Pump Stations

Hazards Addressed: Flooding

Issue/Background Statement: The County of Sacramento, Department of Water Resources

(County) recently completed a partial assessment of its most critical storm water pump stations.

The underlying finding of this assessment was that while the equipment has been well

maintained, the pump stations are plagued with aged and obsolete electrical equipment, code

deficiencies, power supply and transformer issues, and maintenance concerns related to outdated

equipment for which spare parts are no longer available.

According to the EPA report, Taking Stock of Your Water System, (October 2004), the typical

useful life of electrical equipment is shown as the following:

Motor Controls/Variable Frequency Drives -- 10 years

Page 58: 5.1 Mitigation Strategy: Overview · with the National Flood Insurance Program (NFIP) and participation by Sacramento County and the City of Sacramento in the Community Rating System

Sacramento County 5.58 Local Hazard Mitigation Plan Update September 2011

Transformer/Switchgear/Wiring -- 20 years

Computer Equipment and Software -- 5 years

While these numbers are conservative and would likely be used in worst case scenarios such as

in dirty environments, salt spray, or where 100% reliability is critical, they still indicate that

County pump stations are likely to be prone to failure as their service life now exceeds 60 years

at multiple locations. To emphasize the severity of this problem, the following list summarizes

the construction dates of several of the County’s most critical pump stations:

Priority Station Name Date of Construction

1) Pump Station D05 1957

2) Pump Station D02 1959

3) Pump Station D09 1957

4) Pump Station D45 1967

5) Pump Station D11 1961

6) Pump Station D06 1960

7) Pump Station D24 1964

8) Pump Station D33 1969

9) Pump Station D01 1976

10) Pump Station D07 1978

Using this list it can be reasonably deduced that the electrical components at each station exceed

the EPA’s useful life recommendations. In addition, the design guidelines used at the time of

construction did not require redundant power sources such as generator facilities. The sites also

utilize sheet metal buildings which are improperly sized in some locations and are also nearing

the end of their useful lives.

In order to mitigate the potential of future pump station failures, the County is prioritizing pump

station upgrades in an effort to budget for planned civil and electrical work. Planned civil work

includes building replacement and repairs, regrading and repaving existing pump station and

work areas, and fencing and security repairs and upgrades. Planned electrical work includes the

replacement of existing motor control centers, transformers, circuit disconnects, solid state pump

controllers, and wiring, and the placement of generators or automatic transfer switches to

accommodate power supply redundancy.

Planning for these pump station improvements now can help mitigate large scale flooding and

property damage by reducing the risk of catastrophic system failures. Improvements will also

help to maximize County resource allocations during and after large scale natural disasters.

Issue/Background Statement: The focus of this proposal is fire fuel reduction along the

American River Parkway. This particular site is a State Recognized Fire Hazard according to

Sacramento Metropolitan Fire District, one of three partners in this proposal. According to the

Parks Department, this location is in critical need of a large-scale hand crew ―assault‖ to control

the fire fuel at, what is deemed, this urban-wild lands interface. The Parkway features canyons

and bluffs that are excellent breeding areas for wild fires.

Fire fuels come in two classes: invasive species that allow fire to spread quickly and burn

rapaciously, and native vegetation that, under more natural conditions should burn periodically,

now requires thinning or the creation of firebreaks because wild fires are not an appropriate

thinning tool. The following fire fuels must be removed or managed to have a successful fire

fuel reduction project:

Centaurea solstitialis (yellow star thistle) – Introduced unintentionally in the 19th

century

through contaminated seed stock, this noxious invasive plant is poisonous to horses and

crowds out native thistles and other important plants. It comes from Eurasia and requires a

significant amount of person power to remove every piece of the plant. It will burn, spread

and regenerate.

Cortaderia selloana (pampas grass) – This South American natives is lovely to look at, but

spreads quickly. It does not provide natural habitat for indigenous bird populations but it

does encourage non-native and scavenger bird populations. Its wispy tufts are flammable,

sending sparks far and wide.

Spartium junceum (Spanish broom) – Intentionally planted in California for its quick growth

and beautiful yellow flowers in the mid-19th century, brooms are little incendiary devices

that are hard to eradicate, can grow in very hard to reach locales and spread through the air

by wind and birds, in water and by their constant availability at local nurseries.

Arundo donax (giant reed) – ―Imported‖ carelessly from Southern California (where it also

poses a significant fire and invasive problem), giant reed clogs waterways and crowds native

habitat. Burning is not a tool for eradicating this pest, however, because Arundo spreads

from its root ball (fire rarely penetrates that deep) though it will burn if ignited and cause a

fire to spread quickly.

Rubus discolor and Rubus procerus (Himalayan blackberry and Himalyan blackberry,

respectively) thrive in riparian zones, even those that remain parched for most of the year.

These thorny and fruit-bearing bushes grow to enormous thickets. In late summer they

become fire fuel, and yet fire won’t kill it. This plant must be cut severely and then removed

at the root.

Vinca minor (periwinkle) – A lovely-to-look-at water-loving ground cover from western

Europe, periwinkle is pernicious in that it is a perennial that dries and looks dead for most of

the year (summer through autumn) and then comes back robustly. During summer, it would

be a likely candidate for helping wildfire to spread, especially at the suburban-wild lands

interface where it commonly is used, though not contained, in landscaping.

Generally speaking, invasive plant species are the leading cause of degradation of open space

anywhere both from the perspective of damaged habitat and potential fire fuel load; this is

particularly true in California. That said, they are not alone is posing a serious threat of wild fire

within the American River Parkway. Native species also pose threats of fire because they are not

allowed to burn naturally and yet grow into limb-touching arcs and ladder fuel ground cover that

could turn a natural phenomenon into a natural disaster in a flash. The primary fuel species that

will be trimmed or protected by a firebreak include the following:

Quercus virginiana (live oak) – Live oak trees are natural wonders because it is, for lack of a

better term, an evergreen (non-deciduous) oak. Live oaks grow from sturdy bases, sending

many shoots and small branches just above ground level, making them a classic fuel ladder

species.

Cercis occidentalis (western red bud) – This lovely ―blooming tree‖ has a bold spring

presence followed by a drying season into the summer. More shrub than actual tree, this

low-to-the-ground species sends out numerous competing trunks from its roots rather than a

primary trunk. Mature western red buds bloom tall enough off the ground to pose less of a

fuel ladder combustion problem than some of the younger/smaller versions.

Vitis sylvestris (wild grape) – The mammoth woody vines reaching from ground to canopy

can serve as wild fire wands. Like their domesticated siblings, wild grape vines enjoy cool

wet springs and early summer, but the dry heat of late summer and early autumn turn these

plants into fire fuel of a dynamic sort. Selective cutting and removal will be required for our

project.

Both County Parks and Metro Fire are responsible for responding to wild fire and its subsequent

damage, but owing to a host of issues including reduced budgets, small staffs and the

unpredictable natural of natural disasters, neither has the budget or person-power to be proactive

to prevent a wild fire. The two agencies look forward to partnering with the Sacramento

Regional Conservation Corps (SRCC) to make this project happen as soon as possible.

SRCC is excited about the opportunity to be an integral part of this important public safety

project while also having the opportunity to learn about and work within one of our region’s

incredible natural treasures. Corps members will learn to identify various species (beneficial and

invasive), removal and restoration techniques, and firebreak construction skills to help maintain

the integrity and ethereal beauty that is the American River Parkway.

Other Alternatives: No Action

Existing Planning Mechanisms through which Action will be Implemented: The

Sacramento Regional Conservation Corps is currently working on a fuels reduction program in

specific areas of the Parkway. This proposal would extend that work to other areas within the

Parkway using their existing crews and equipment.

Responsible Office: Sacramento Metropolitan Fire District
