Boulder Hazard Mitigation Plan <br />Community Profile <br />2.0 Community Profile <br />2.1 Geography and Climate <br />Our unique geography and climate help shape the hazards we face in Boulder County. We live in <br />environments ranging from the rolling prairies in the eastern part of the County to the rugged mountains <br />and alpine forests in the western regions. We live at elevations climbing from 5,000 feet on the high plains <br />to more than 12,000 feet at the Continental Divide which forms our western border. <br />Our climate is as varied as our topography. In winter we endure frequent snowstorms and temperatures as <br />low as minus 30 degrees Fahrenheit. But, as those of us who live here know snow today does not mean <br />temperatures in the 60s tomorrow. With gusts of 120 miles per hour or more, we also experience some of <br />the strongest winds in the continental United States. Summer typically brings us temperatures reaching the <br />upper 90s and low levels of humidity. We receive an average of 18.17 inches of moisture each year which <br />means that we enjoy at least some sunshine most days. <br />2.2 Population <br />At the 2010 census our County had a population of 294,571. According to the State Demography Office, <br />population estimates as of 2020 for Boulder County is 330,860 residents.
