- November 12, 2019: Applied Ecological initiated the watershed plan for the Crystal Creek Watershed. Creation of this plan will continue into 2020.
- November 2019: The culvert project at all five locations was substantially complete.
- September 3, 2019: The City Council selected Applied Ecological Services to develop a watershed plan for the Crystal Creek Watershed.
- Summer 2018: The City continues the engineering and permitting process for the culvert replacements along Crystal Creek at Broadway Avenue, Country Club Road, Barlina Avenue, McHenry Avenue, and Dartmoor Drive.
- February 22, 2018: City staff met with the Country Club Area residents for a final check-in. View the presentation
- January 22, 2018: The City mailed letters to all residents in the study area and invited them to the Open House.
- August 31, 2017: City staff met with residents of the Country Club Area. Meeting minutes are available here.
- July 31, 2017: The City mailed letters to all residents in the study area and invited them to the Open House.
- July 18, 2017: A City Council Presentation occurred to review the stakeholder engagement process, review and refine improvements, and reduce the risk of flooding.
- June/July 2017: The City experienced successive and excessive rain events, which led to June-July's total rainfall of almost 20 inches, over double the normal average.
- 2014-2016: The City’s stormwater consultant further evaluated the conceptual design, outlined in the 2010 Crystal Creek Flooding Analysis. The cost-benefit of the improvement is very low and other ideas were explored.
- 2013-2014: A FEMA regulatory hydrology model was created. Unfortunately, the model did not show favorable results for removing residents from the FEMA floodplain as originally anticipated. A review of the leakage from the Lake was extensively explored and determined to not be factual.
- July 20, 2010: The Crystal Creek Flooding Analysis was completed. To review the study, see below under completed studies.
- March 2009: A flooding study was completed which helped determine the causes of the flooding and conceptual solutions. Due to the complex nature of the Country Club area, a separate study was initiated for this area.
- August 2007: Successive rain events led to Crystal Lake receiving between 11 and 12 inches of rainfall which produced the highest lake level ever recorded and areas around the lake experienced significant flooding.
This area was annexed into the City in 1929. Many of these homes were initially built in the 1920s and 1930s as summer cottages and three-season homes. As the demand for year-round homes in Crystal Lake grew, these homes were converted to year-round residences. Flooding in this area occurs in the FEMA floodplain, along Crystal Creek. Flooding also occurs due to pocketed areas (low spots with no outlet), which may or may not receive stormwater from adjacent roadways and the duration of the flooding (length of standing water) varies by location.
