VILLAGE OF WILMETTE ANNEX HAZARD MITIGATION PLAN POINT OF CONTACT Primary Point of Contact Brian King, Police Chief 710 Ridge Road Wilmette, IL Telephone: Address: Alternate Point of Contact Alejandra (Alex) Cease, Asst. to the Chief of Police 710 Ridge Road Wilmette, IL Telephone: Address: JURISDICTION PROFILE The following is a summary of key information about the jurisdiction and its history: Date of Incorporation: 172 Current Population: 27,087 as of 2010 Census Population Growth: Based on the 2010 census, the Village of Wilmette experienced a decrease of 2.04% in population from Wilmette sustained a population size of 27,651 in 2000 compared to the 2010 Census which depicts a population size of 27,087. Location and Description: Wilmette is located approximately 15 miles north of downtown Chicago in New Trier Township, in Cook County. The Village extends approximately five miles west from Lake Michigan and is approximately one mile wide (its area is 5.4 square miles). Its municipal neighbors include Evanston and Skokie to the south, Glenview to the west and Kenilworth and Northfield on the north. The eastern border of Wilmette is Lake Michigan. The Village of Winnetka and part of the western boundary of Wilmette are separated by an unincorporated, residential area. Brief History: The present Village of Wilmette is distinct among North Shore communities because it was created by the 1924 merger of two older villages, Wilmette and Gross Point. The origins and development of these two communities differed, and this difference is still visible on the landscape. On the east, Wilmette developed on a wooded tract bordering Lake Michigan. On the west, Gross Point was the center of a German immigrant, farming community that spread across the open fields west of what is now Ridge Road. Native Americans were the first people to inhabit this region. European contact began with the arrival of French explorers three centuries ago. At that time, Potawatomi people were living in this area. In 1953, a prominent Wilmette landmark, the Baha i House of Worship, was completed forty years after its construction began. The population grew from 1,162 in 1950 to 32,134 by When the Village celebrated its centennial in 1972, there remained little vacant land. Wilmette had become a mature suburb, one whose coming challenges would be more of preservation and revitalization than of growth. Climate: The climate is warm during summer when temperatures tend to be in the 70s and very cold during winter when temperatures tend to be in the 20s. The warmest month of the year is July with an average maximum temperature of 3.20 degrees Fahrenheit, while the coldest month of the year is January with an average minimum temperature of degrees 114-1

2 Cook County Multi-Jurisdictional Hazard Mitigation Plan; Volume 2: Planning Partner Annexes Fahrenheit. Temperature variations between night and day tend to be moderate during summer with a difference that can reach 20 degrees Fahrenheit, and fairly limited during winter with an average difference of 17 degrees Fahrenheit. The annual average precipitation at Wilmette is 36.0 Inches. Rainfall in is fairly evenly distributed throughout the year. The wettest month of the year is August with an average rainfall of 4.4 Inches. Governing Body Format: The Village of Wilmette is governed by a Board of Trustees and a Village President (Mayor). This form of government combines the political leadership of elected officials with the professional administrative experience of an appointed Village Manager. This body of Government will assume the responsibility for the adoption and implementation of this plan. The six members of the Village Board of Trustees are elected atlarge for staggered, four-year terms. By serving at-large, each trustee represents the entire Village. There is a two-term limit for members of the Village Board and the Village President. Wilmette operates 12 Village departments including: Cable Department, Community Development Department, Engineering Department, Finance Department, Fire Department, Health Department, Historical Museum, Law Department, Police Department, Public Works Department, Water Plant, and Village Manager s Office. Development Trends: Over the past several years, the Village has conducted several business development studies to ensure a business development strategy that is successful over time. The Village applied for and received planning assistance from an Urban Land Institute (ULI) Technical Assistance Panel. The goal was to create a plan to revitalize and reinvigorate Wilmette s Village Center and West Village Center. The ULI Technical Assistance Panel consisted of a group of real estate development experts, urban planning and design professionals, and community development leaders. This group evaluated qualitative and quantitative information related to the community s vision and statement of need and offered objective recommendations to help the Village reach its goal CAPABILITY ASSESSMENT The assessment of the jurisdiction s legal and regulatory capabilities is presented in Table The assessment of the jurisdiction s fiscal capabilities is presented in Table The assessment of the jurisdiction s administrative and technical capabilities is presented in Table Information on the community s National Flood Insurance Program (NFIP) compliance is presented in Table Classifications under various community mitigation programs are presented in Table

Central U.S. Earthquake Consortium (CUSEC) State Geologists used the entire column of soil material down to bedrock and did not include any bedrock in the calculation of the average shear wave velocity for the column, since it is the soil column and the difference in shear wave velocity of the soils in comparison to the bedrock which influences much of the amplification. «58 41 GROSS POINT RD GOLF RD CRAWFORD AVE NORTH SHORE CHANNEL DEMPSTER ST Base Map Data Sources: Cook County, U.S. Geological Survey. ^ Miles
