1930s and 1940s

Historical-West-Colfax-Avenue.png
As the West Colfax Avenue corridor developed over time beginning in the 1930s and booming in the 1940s, the natural drainage channel was obliterated and replaced with paved streets, parking lots and other hard surfaces incapable of absorbing water and aggravating conveyance of runoff in a major storm event. A variety of smaller pipes were installed in places, some of which still exist.

 

 

 

 

 

1977

Drainage-Map.png
Mile High Flood District (MHFD) and Lakewood published the Dry Gulch and Tributaries Flood Hazard Area Delineation (FHAD), which mapped the 100-year floodplain along North Dry Gulch. At the time, the only open channel segments remaining were between Wadsworth and Vance Street and a short stretch west of Lamar Street.

 

 

 

 

 

 

1996

Lakewood acquired property between Newland and Lamar and constructed the Lamar Detention Pond to help reduce flooding downstream.

Whitlock-Recreation-Center-Detention-Pond-site.png

Lakewood completed construction of the Whitlock Recreation Center at the northwest corner of Colfax and Dover, reserving the southern end of the property for a future detention pond to help reduce flooding downstream. This detention pond will be included with the North Dry Gulch Improvements.
