Site work and paving for a mixed-use development in Denver, Colorado. Completed plans call for site work for a road / highway; for paving for a road / highway; sidewalk / parking lot; sidewalk / parking lot; and water / sewer project.

The storm drain system improvements in the Marson Lake North Drainageway aim to separate stormwater flows from the Bowles Lateral, improve drainage and alleviate high ground water near the properties adjacent to the Bowles Lateral at Saratoga Place, and improve the overall drainage and reduce street flow through the project area. The new system will collect and convey flows from West Wagon Trail and South Field Way to the existing storm drain system downstream of the Glenbrook Pond. Storm flows will be separated from the Bowles Lateral with the improvements. All work on the Bowles Lateral will be completed in the off-season of the ditch. The project will be completed in two phases. Phase I is from the Glenbrook Pond outfall to upstream of the Bowles Lateral and includes installing 42- and 48-inch storm drain trunk line with laterals and inlets in West Garrison Street and South Garland Street, then crossing the Bowles Lateral to West Saratoga Place. Sanitary sewer and water lines will be adjusted as well as the Bowles Lateral which will be piped via 60-inch pipe. A headwall and wingwalls will be constructed at the culvert entrance. An 8-inch French drain will be installed along the new Bowles Lateral pipe in the vicinity of the ditch to collect groundwater. Curb Ramps, curb, gutter, and sidewalk replacement, as well as street restoration are also included.
