I. Discovery and Risk Map The FEMA Risk Mapping, Assessment, and Planning, or Risk MAP program helps communities identify, assess, and reduce natural hazard risks. Through Risk MAP, FEMA provides information to enhance local mitigation plans, improve community outreach, and increase local resilience to hazards.
During Discovery, FEMA
gathers information about local hazards and hazard risks;
reviews mitigation plans to understand local mitigation capabilities, hazard risk assessments, and current or futures mitigation activities;
supports communities within the watershed or county to develop a vision for its future;
collects information from communities about their hazard history, development plans, daily operations, and hazard management activities; and
uses all information gathered to determine which areas of the watershed require mapping, risk assessment, or mitigation planning assistance through a Risk MAP project.
II. Community Descriptions
Clallam County Clallam County is located on the Olympic Peninsula, an area situated on the northwestern portion of Washington State. The county has a total landmass of 1,739 square miles. It is bordered by the Pacific Ocean on the west, the Strait of Juan de Fuca on the north, and Jefferson County on its eastern and southern borders. As of 2010, the county had a population of 71,404 people. Approximately one quarter of Clallam County’s residents live in Port Angeles, the county’s most populous city and the county seat. The most prominent industries in the county are educational services, health care, or social assistance. Approximately twenty percent of the total work labor force in Clallam County work in these industries. The majority of the county’s population resides within cities or near cities along the coast. Much of Clallam County’s interior is home to a portion of Olympic National Park. Most jurisdictions in Clallam County participate in the National Flood Insurance Program (NFIP). All participating jurisdictions have regular participation status in the NFIP.
Jefferson County Jefferson County is also located on the Olympic Peninsula. The county has a total landmass of 1,814 square miles. The county is bordered by the Pacific Ocean on its west, Clallam County on its north, the Salish Sea on its east, and Greys Harbor and Mason Counties on its southern border. As of 2010, the county had a population of 29, 872. Approximately one third of county residents live in Port Townsend. Port Townsend is the only incorporated community in Jefferson County. Like Clallam County, the most prominent industries in the county are educational services, health care, or social assistance. Approximately twenty percent of the work force in Jefferson County work in these industries. Traveling east and west in Jefferson County is hindered by the mountainous terrain of Olympic National Park. In order to most efficiently travel from Western Jefferson County to Eastern Jefferson County and vice versa, one needs to take US Route 101 through Clallam County.
JEFFERSON AND CLALLAM COUNTIES DISCOVERY REPORT – JULY 2013 4 4
All jurisdictions in Jefferson County participate in the NFIP. Jefferson County’s Unincorporated Areas and Port Townsend have regular participation status in the NFIP.
Hoh Tribe The Hoh Tribe is located in Western Jefferson County. The Hoh Reservation is bordered by the Pacific Ocean to its west and the Hoh River to its north. Tribal lands are also surrounded by Olympic National Park. Many tribal members make their living through fishing. The Hoh Reservation is currently participating in the NFIP under emergency participation status.
Jamestown S’Klallam Tribe The Jamestown S’Klallam Tribe is located in Eastern Clallam County. Most of the tribe’s land is located near U.S. Route 101, and their commercial and administrative centers are located adjacent to Sequim Bay. Many of the tribal members live in Clallam County near the Jamestown Cemetery. The Jamestown S’Klallam Tribe is currently not participating in FEMA’s NFIP.
Lower Elwha Klallam Tribe The Lower Elwha Klallam Tribe is located in Clallam County and is located approximately 3 miles west of Port Angeles. The Salish Sea touches the Reservation’s northern boundary. Reservation lands total approximately 2.8 square miles, and the tribe currently has close to 1,000 members. The Lower Elwha Klallam Tribe currently is participating in FEMA’s NFIP.
Makah Tribe The Makah Tribe is located in the northwestern Corner of Clallam County. The Makah Reservation is bordered by both the Salish Sea and the Pacific Ocean. The main highway leading to the Makah Reservation is State Route 112. Fishing, forestry, and tourism are major economic industries of the Makah people. The Makah Tribe is currently not participating in the NFIP.
Quileute Tribe The Quileute Tribe is located in Southwestern Clallam County. The Pacific Ocean is located on its western boundary, and the reservation is surrounded by Olympic National Park. Tourism is a significant part of the tribe’s economy. Washington State Route 110 provides easy access to and from the Quileute Reservation. The Quileute Tribe is currently participating in the NFIP under emergency participation status.

III. Project Description and Methodology Discovery is the process of data collection, including information exchange between all governmental levels of stakeholders, spatial data presentation, and cooperative discussion with stakeholders to better understand the area, decide whether a flood risk project is appropriate, and if so, to collaborate on the project planning in detail. The Discovery process and requirements are defined in Appendix I – Discovery (June 2012), and Operating Guidance No. 04-11, Risk MAP Meetings Guidance (July 2011). In addition, there are several tools that were used to support the efforts. Region X initiated this Discovery effort in the fall of 2012, with data collection, community interviews, a meeting with stakeholders in the watershed, and development of recommendations based on an analysis of data and information gathered throughout the process. Collected data sources are shown in Table 2. Figure 2. Data Sources for Region X Discovery (project-specific data sources in Appendix)

The Region X Discovery data collection entailed a massive collection of tabular and spatial data for all communities from Federal and State sources, as well as information collected through interviews with each community. Data was used primarily in two ways – tabular data was documented on a Community Fact Sheet, and spatial data was included in the Discovery Geodatabase, and is displayed on the Discovery maps, where appropriate. Full-sized Discovery maps are included in the appendix. The second phase of the Region X Discovery effort involved a review of the collected data with community officials through a phone interview, and a request for additional information. Prior to the interview, community officials received information about the Discovery process, and a Fact Sheet and Interview Reference Map for their community. Communities were asked to identify “Areas of Concern” (AOC) based on their local knowledge and analysis of the data shown on the
JEFFERSON AND CLALLAM COUNTIES DISCOVERY REPORT – JULY 2013 9 9
map. The Areas and Points of Concern (mapping needs, desired mitigation projects, etc.) were documented in the Discovery Geodatabase and discussed during the Discovery Meeting. Figure 3. Example of a Factsheet Provided Prior to Community Interview (All Community Factsheets are located in the Appendix B)

Figure 4. Example of a Reference Map used at the Discovery Interviews (All Community Reference Maps can be found in the Appendix B)
JEFFERSON AND CLALLAM COUNTIES DISCOVERY REPORT – JULY 2013 11
The third step in the Discovery effort was to hold community-specific Discovery Meetings to facilitate discussion and data analysis of study needs, mitigation project needs, desired compliance support, and local flood risk awareness efforts. During these Discovery Meetings, FEMA and STARR, FEMA’s contractor, collaborated with each of the communities that are participating in this effort. The purpose of these meetings was to meet the community officials involved in the Discovery effort, continue the discussions that were started during the community interview, and collect additional community data that will aid in the Discovery effort. The fourth phase of the Discovery effort involves an analysis of the data and information collected during the interviews and subsequent community visits and also may include recommendations as to the future relationship and activities between FEMA and the communities. The Final Discovery Map indicates desired study areas and mitigation project locations, and the Discovery Report documents the results of data collection and conversation. If a Risk MAP project is to be initiated in this watershed, Discovery will be concluded with the finalization of a project scope and signed Partnership Agreements, which indicate that all affected stakeholders agree to the terms of a funded project, including communication and data responsibilities. The basis for deciding if a Risk MAP project will be initiated depends upon FEMA Regional priority, funding and/or available resources.

IV. Risk MAP Needs The results of the data collection and interviews were thoroughly discussed at the Discovery Meetings. The following sections include issues and conditions that exist in Jefferson and Clallam Counties that can be considered Risk MAP needs, to be addressed with Risk MAP projects. Details and background on all issues can be found in the interview notes, meeting notes, Hazard Mitigation Plans (HMPs), and other files included in the appendix.
i. Current Studies and Plans
Hazard Mitigation The Disaster Mitigation Act of 2000 (P.L. 106-300; 42 USC 5131 ff.) and the Federal Emergency Management Agency’s subsequent Interim Final Rule, 44 CFR Part 201, requires all states and communities to develop natural hazard mitigation plans in order to be eligible for federal Pre-Disaster Mitigation Grant funds and/or post-disaster Hazard Mitigation Grant Program funds. Hazard mitigation plans attained through Discovery are identified in the table below:

Floodplain Studies Production of county-wide Flood Insurance Rate Maps (FIRMs) and a Flood Insurance Study (FIS) for Clallam County began during Map Modernization; however, complications arose due to issues concerning a levee policy within the county, and production of these materials was put on hold. Updated flood maps will be issued once the levee policy is finalized, which will replace the current effective maps. The current status for effective flood maps within Clallam County can be found in the table below. In late 2012, Clallam County received funding to update current GIS data and perform HAZUS analyses. This data should help the county with making more effective hazard mitigation decisions and identifying specific hazard mitigation needs in the county. Table 3.

Effective FIRMs and FISs within Jefferson County are over thirty years old. Jefferson County’s study went effective on March 15, 1982 and Port Townsend’s study went effective on July 19, 1982. The Hoh Tribe has not been mapped. FEMA’s Coordinated Needs Management Strategy (CNMS) database was created in 2011 for Region X to coordinate the management of future floodplain mapping needs. This database tracks and identifies the status and needs of existing floodplain studies based on change indicators that may have occurred since the date of the analysis to help prioritize future floodplain study needs. Currently validation for streams in Jefferson and Clallam Counties are unknown. CNMS data can be viewed on the FINAL Discovery Maps.
ii. Hazard Events
Wildfires Wildfire risk within communities depends on land use and development. Some communities don’t have significantly forested areas and therefore report their wildfire threat as minimal. Others state that wildfires are a great concern to them and much property and infrastructure are vulnerable to this natural hazard. The table below is a compilation of wildfire data attained from local governments and state and federal agencies.
Table 4. Clallam County and Jefferson County Wildfire Risk
Community County Notes

Earthquakes Clallam and Jefferson Counties have experienced historic earthquakes and have several fault lines. A common concern for almost every community is that many of their critical buildings are not retrofitted to withstand the impact of an earthquake. Information on fault lines, earthquake events, and specific details on earthquake awareness was collected from each community and is shown in the table below. A much larger area of earthquake risk is created by the Cascadia subduction zone which extends from Vancouver Island to Northern California. If rupture occurs, the Cascadia subduction zone can produce very large earthquakes (9.0 or greater).
JEFFERSON AND CLALLAM COUNTIES DISCOVERY REPORT – JULY 2013 18 18
Table 5. Clallam County and Jefferson County Earthquake Risk
Community County Notes
Clallam County
Clallam
• Trenched Lake Creek fault has recently been determined to be active. • Most Powerful modern earthquake to hit the area was in 1909. Caused damage to many areas within the county. • Many significant buildings need retrofitting in the county. They include hospitals and public buildings. Grant proposals have been submitted to retrofit many of these buildings.

Flooding A plethora of issues were addressed that concerned flooding. They included inaccuracies of floodplain representation on effective FIRMs, areas were flooding could damage public and private property, and mitigation projects undertaken to limit flooding. Table 7 identifies flooding concerns as they pertain to each individual community. There have been a total of 103 flood insurance claims made in Clallam County and 42 flood insurance claims made in Jefferson County since 1978. A total of 20 repetitive losses have been identified in both counties, 6 in Jefferson County and 14 in Clallam County. There have been some Letters of Map Change (LOMC) issued across these counties with many near the Bogachiel River and Sequim Bay. Locations of LOMCs in each county can be found on the Final Discovery Maps.

county from Jefferson County. • The county recommended that the Dungeness river be restudied. • Several areas have been identified as being prone in the county.
See AOC layer on Final Discovery Map.
City of Forks Clallam
• The city disagrees with a flood hazard area on the preliminary
SFHA on the Discovery Map. See “Area of Concern” layer on Final Discovery Map. • Flooding near schools beside a Baptist church is caused by flooding
from culverts. See AOC layer on Final Discovery Map. • Culverts have been repaired in the city and city claims they
eliminated flood risk. • The city wants to take a gravel pit that is shown in a floodplain and
use it for stormwater management. • City identified as having high vulnerability to flooding in HMP.
Jamestown S’Klallam Tribe
• Jimmy Come Lately Creek flow direction has changed (area was restored). One side of the creek no longer floods. • A project has been initiated as a result of flooding on Hwy 101. • Dean Creek has a new flow direction and has been restored. • Increased flows from stream to shoreline are causing additional
erosion and stormwater flooding. • Majority of tribal properties are classified as being highly
vulnerable to flooding. See Jamestown HMP.
Lower Elwha Klallam Tribe
• Tribe claims that the east side of the levee in reservation should be zone X. Certification of the levee is in question. • Tidal flooding has been increasing in frequency and magnitude.
USACE has expanded storage facilities in an effort to offset. • Charles road can get inundated with flooding. • According to Tribe’s HMP, all homes and tribal facilities in the
lower valley are potentially vulnerable to flooding. • Lower Elwha River identified as being a flooding concern. See
AOC layer on Final Discovery Map.
Makah Tribe • Suez River is subject to flooding. • Biggest flooding event was a culvert blockage a few years ago.
JEFFERSON AND CLALLAM COUNTIES DISCOVERY REPORT – JULY 2013 24 24
Community County Notes
City of Port Angeles
Clallam
• Significant changes at the Valley Creek area since the release of the current effective FIRMs: Estuary has been moved, a log pond has been removed. Area looks correct on the Discovery Map. • Water runs down street, backs up sewer system and stormwater
outlets at the mouth of valley creek. See AOC Layer. • Two culverts that are subject to blockage and flooding are being
treated. Issue is being treated as a maintenance issue and isn’t in HM Plan. • Downtown area can become flooded by various sources: high tides,
creeks, and stormwater flow. Many of these areas are classified in the AOC layer. • RR with Riprap protects most of the bluffs. Often armoring is
damaged, and projects are implemented to repair as needed. • City maintains a stretch outside of City limits where the protection
is eroded by storm surges. • Severe erosion or run-up is occurring on the inside of Ediz Hook. • Identified as having medium vulnerability to flooding in HMP.
City of Sequim
Clallam
• Culvert south of the marina replaced with a bridge. • Areas flood but ponding dissipates quickly. • Sequim does not have a storm drain system. It relies on a filtration
system. During a heavy rain event there is a lot of minor localized
flooding that impacts roads.
• Identified as having low vulnerability to landslides/erosion in
HMP.
• See AOC layer for areas in the city that are prone to flooding.
• Undersized culverts along Bell Creek have caused some flooding.
See AOC layer.
Hoh Tribe
• Log jams on the Hoh River can cause severe flooding at various locations • The northern area of the Hoh Reservation is susceptible to
flooding. Some homes are at this location • Roads have been resurfaced, no hydraulic changes
Jefferson County
Jefferson
• Some of the population of Jefferson County disagrees with the current effective NFIP maps. • Overall the county feels the floodplains are accurate with a few
areas possibly not correct, such as the shoreline. • Stormwater flooding occurs in northern Port Ludlow. Having
difficulty getting a drainage ditch approved by local environmentalists. See AOC layer. • The county is identified as being at low risk and low vulnerability
to flooding according to its HMP. • Several areas have been identified as being flood prone at the
Discovery Meeting. These areas are identified in the AOC layer.
City of Port Townsend
Jefferson
• City requested that we more closely examine flooding in the area around the marina. See AOC layer on Final Discovery Map.
• No known significant areas of development that might be impacted by the floodplain.
• Severe erosion along the coast. Seawall doesn’t flood but wave action overtops into buildings.
• Around Gaines Street area – water can back up during high tides because storm drains cannot drain.
• No known significant areas of new or proposed development are anticipated to impact the floodplain.

iii. Mitigation Projects and Other Relevant Data
Mitigation Projects There were several potential, desired, and in progress mitigation projects that were identified throughout the Discovery process. Most of these projects were identified through researching Hazard Mitigation Plans or speaking to community offices. Several of these projects are identified in figure 9 below. More information of mitigation projects can be found in the appendix of this report. Figure 9. Listing of Various Projects in Clallam and Jefferson Counties *

*No mapping data was provided for these items. Areas of Concern As determined through correspondence with local community officials, the areas of concern list is displayed below by community. Some communities did identify areas outside of their jurisdiction that were a concern to them. The concerns are labeled with ID numbers corresponding to the specific concern’s location on the Final Discovery Map. Areas of concern were identified during both the Discovery Interviews and Discovery Meetings. AOCs identified at the Discovery Meeting will have “(Meeting)” at the end of their description. Much of these areas were identified at a scale much larger than the scale of the Final Discovery Map, many AOCs were identified at a scale of less than 1:1,000. Therefore, some areas on the Final Discovery Map are difficult to individually identify. It is recommended that one examine the “Areas of Concern” feature class in ArcMap. This feature class is located in the Discovery Geodatabase and the Appendix D folder. Viewing the AOC feature class in ArcMap will allow one to examine each AOC at a scale that is easily discernible.

Rather than identifying all of their AOCs during Discovery Meetings and Interviews, some communities opted to additionally provide us GIS data that already has information pertaining to areas of concern. Some of the data that was provided is spatially complex and contains extensive amounts of data. The Figure below provides a listing of GIS data that communities provided to help identify AOCs. GIS data that communities provided for this report can be found in Appendix D under “Additional Resources”. Figure 10. Areas of Concern as Identified by Community Attained GIS data

LiDAR Data LiDAR data was acquired from the Puget Sound LiDAR Consortium. Through the Puget Sound LiDAR Consortium website (http://pugetsoundlidar.org/), one can download LiDAR data that covers much of the study area. LiDAR data is very useful in producing accurate, high-quality regulatory and non-regulatory NFIP projects. The map and table below provides some details about the LiDAR data one can attain from the website. For further information, please visit the Puget Sound Consortium website.

In addition to the LiDAR data mentioned above, the Jamestown S’Klallam tribe informed FEMA and STARR that it possesses LiDAR data of the lower 12 miles of the Dungeness River, which was completed in 2008. It also has LiDAR data of the Grey Wolf and Upper Dungeness Watersheds. This dataset was completed in 2011. Both datasets have a resolution of 1 meter. One can view boundary feature class shapefiles of these datasets in Appendix D under the “Additional Resources” and “Community Attained GIS Data” folders.

V. Compliance Data collected from CIS indicated that none of the communities in Jefferson and Clallam Counties had any variances to their floodplain management ordinances, so it may be assumed that the communities are regulating to at least the minimum criteria required by the NFIP.
VI. Communications During Discovery Interviews and Discovery Meetings, communities indicated that they were interested in learning more about Risk MAP’s communications support, and were open to a future meeting with FEMA to learn about how they can improve their flood risk communications program. Varying forms of communication strategies are currently in use throughout the counties for the purpose of reaching out to citizens in cases of emergency. These forms of communication include but are not limited to:
Reverse 911 (Port Angeles & Clallam County)
Social Media (Sequim & Jefferson County)
JEFFERSON AND CLALLAM COUNTIES DISCOVERY REPORT – JULY 2013 37 37
Town Newsletters & Daily Newspapers (Jefferson County, Port Townsend & Sequim)
Nixel – web based text messaging alert system (Jamestown S’Klallam & Port Townsend)
Local Television and Radio (Jefferson County, Port Townsend & Port Angeles)
Siren Systems (Lower Elwha, Port Townsend & Makah)
Open House Meeting – educational outreach (Clallam County)
All compiled information on communication forms that communities use can be found in the Meeting Minutes in Appendix B of this report. To help communities improve their abilities in effectively communicating risks to the public, FEMA has offered to assist communities with this process through a variety of means such as providing HAZUS training and other information relating to HAZUS and providing outreach materials and regional newsletters on current FEMA activities. Some communities have also expressed interest in being involved in future FEMA activities. For example, the city of Port Angeles would like to be involved in any future LiDAR projects that FEMA may undertake in the future.
VII. Close Local officials in the communities were very interested in the Risk MAP Discovery process and are open to learning more about how they can begin to develop resilience to all hazard events. Natural hazards cannot be avoided fully. Through Discovery and the Risk MAP process, communities can begin to develop resilience by increasing the desire to promote action to reduce the impacts of hazards and facilitate recovery. They identified several areas for FIRM updates and areas in which they could use additional FEMA support. It is recommended that FEMA review and evaluate the guidance document outlining Mitigation Planning Technical Support with communities, once finalized. The local officials in Clallam and Jefferson Counties would benefit from the implementation of future Risk MAP projects.
