Dibble provided survey and civil engineering services to the Durango Jail, a 14-acre, 179,881-sf site at the southeast corner of 35th Avenue and Durango Street.

The site consists of buildings, asphalt parking lots/drive aisles, landscaping and unimproved dirt/gravel areas. Retention was not provided within the 14-acres and there was no clearly defined drainage patterns for the site. This project designed drainage improvements consisting of surface drainage features such as curb and gutter, valley gutter, storm drain systems, and on-site retention basins. The parking lots and drive aisles were not reconstructed; drainage improvements were implemented to convey the runoff to new retention basins.
