The overall population has increased only.825% since Population growth after the 2010 Census has increased with the City s population growing 3.1% from 2010 to Location and Description Located just about 10 miles north of downtown Seattle, and about 3 miles east of the Puget Sound in south-most Snohomish County, the City has a balanced mix of residential homes, commercial properties, parks, and Lake Ballinger all within its 4-square-mile limits. Brief History The residential community of Mountlake Terrace began with the speculative construction of homes for returning World War II veterans and their young families. A bustling town center formed during the early decades that included a department store, pharmacy, grocery store, dry cleaners, beauty shop, and restaurants. The opening of Alderwood Mall in neighboring Lynnwood as well as two fires in the Mountlake Terrace town center in the 1980s resulted in a downturn for some local businesses. The Town Center has now begun revitalization through subarea planning and a Main Street project that runs through its core. Climate Mountlake Terrace has a typical Western Washington climate with mild temperatures year round. Winter average is in the low 40s and summer average is in the low 60s. The average precipitation range for the city is about 1.5 inches of rain in the summer to an average high of 5 inches in the late fall/early winter. Governing Body Format Mountlake Terrace is governed by an elected seven-member City Council. The Council oversees various boards and commissions and appoints a City Manager to oversee and manage all the departments of the City: Community Relations, Administrative Services, Police, 15-1

2 Community & Economic Development, Recreation and Parks, Public Works, and Engineering Services. The City contracts out for Fire/EMS and Court/Jail Services. The City also provides water, sewer, and stormwater utility services. Development Trends With the vision of having a revitalized downtown, the City Council adopted (in 2007) a Town Center Planned Action Ordinance (PAO) for its 68-acre downtown. And in 2013, a second PAO was adopted for an adjacent Freeway/Tourist zoning district. As a result of these two plans, several larger scale mixed-use developments have been developed or are being planned for in the Town Center and Freeway/Tourist areas. Development in the city is largely infill due to the limited amount of vacant land, and future development will most likely remain being focused in the Town Center and Freeway/Tourist areas. One of the attractive features of these two planning areas is that they are located walking distance to an existing Transit Center and freeway station as well as a future Link light rail station JURISDICTION/DISTRICT-SPECIFIC NATURAL HAZARD EVENT HISTORY Table 15-1 lists all past occurrences of natural hazards within the jurisdiction. Repetitive loss records are as follows: Number of FEMA Identified Repetitive Flood Loss Properties: 1 Number of Repetitive Flood Loss Properties that have been mitigated: The area around the repetitive loss property has been mitigated by the Hall Creek culvert removal project HAZARD RISK RANKING Table 15-2 presents the ranking of the hazards of concern CAPABILITY ASSESSMENT The assessment of the jurisdiction s/district s legal and regulatory capabilities is presented in Table The assessment of the jurisdiction s/district s administrative and technical capabilities is presented in Table The assessment of the jurisdiction s/district s fiscal capabilities is presented in Table Classifications under various community mitigation programs are presented in Table HAZARD MITIGATION ACTION PLAN AND EVALUATION OF RECOMMENDED INITIATIVES Table 15-7 lists the initiatives that make up the jurisdiction s/district s hazard mitigation plan. Table 15-8 identifies the priority for each initiative. Table 15-9 summarizes the mitigation initiatives by hazard of concern and the six mitigation types. 15-2

3 15.7 STATUS OF PREVIOUS PLAN INITIATIVES Table summarizes the initiatives that were recommended in the previous version of the hazard mitigation plan and their implementation status at the time this update was prepared FUTURE NEEDS TO BETTER UNDE RSTAND RISK/VULNERABILITY Updating our stormwater Comprehensive Plan to include information/analysis about flooding will be useful in understanding future risk related to flooding. We may also want to explore using HAZUS mapping and analysis at a local level to explore our community s risk in greater detail INTERNAL PLANNING PROCESS The internal planning process is described in Appendix E of this document ADDITIONAL COMMENTS N/A 15-3

5 TABLE HAZARD RISK RANKING Rank Hazard Type Risk Rating Score (Probability x Impact) Description of Risk (Describe the community impacts) 1 Earthquake 54 Majority of single family residential buildings are made of unreinforced masonry and comprise 12.5% of housing stock. Damage to infrastructure such as broken pipes (such as water, sewer, gas) and collapse of bridges across I-5 (220 th, 228 th and 236 th St W) and road damage impeding emergency services, relief and recover efforts. 2 Severe Storm 42 Large quantity of mature evergreen trees are located in single family residential areas which can cause structural and property damage and life endangerment from falling limbs and downed trees due to wind, rain, snow or ice storms. Citywide power outages affecting homeowners and businesses, flooding. 3 Climate Change 36 Increase intensity and frequency of severe storms; reduction in available resources for energy and potable water; loss of vegetation; increased wildfire potential; decline in air quality. 3 Flood 36 Property, structure and ecological damage along Hall and Lyon Creek drainages. Health hazard from sewer system overflow and associated health risks. Impact transportation systems by blocking east/west routes (216th, 220th St SW, 226th Pl SW and 228th /Lakeview Drive) 4 Dam Failure 12 Lyon Creek - Downstream stream impacts to stream channel and property, fish habitat destroyed up- and down- stream of dam. Dam failure outside City, such as Spada Lake would affect source of city s water supply. 4 Landslide 12 Soil, rock and tree debris would block Hall and Lyon Creek (and tributaries) damming water behind debris, or along I-5 corridor in a cut bank through the City impacting regional transportation. 5 Volcano/Lahar 11 Air quality impacts on human health from smoke and ash outfall from a regional event; impede use of roadway; damage to vehicles and generators air filters (backup power system from ash). 6 Tsunami 6 Lake Ballinger has potential to develop a seiche from high winds or earthquake that would affect the Ballinger Park clubhouse, parking lot and other site improvements, residences and docks on the lake, and damage to residents upstream along Hall Creek. 15-5
