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 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.
Road and parkway flooding also occurs which subsides after the event.
