ENVIRONMENTAL SERVICES
Statement of Purpose
The Environmental Services Program assures proper conveyance of storm water, management of single family solid
waste, and protection of air and water quality.
Description
The Environmental Services Program is responsible for managing approximately 49 miles of storm sewer pipe, 11 wet
ponds, 26 water quality facilities, seven miles of master drainage ways, and the Colorado Discharge Permit System
(CDPS) Municipal Separate Storm Sewer System (MS4) permit. The program is also responsible for the concrete
replacement program. The Sweeping Program assures that the 224 lane miles of paved roadways are swept in
compliance with Village requirements. The program is also responsible for the residential trash and recycling program,
large item pick-up, and household hazardous waste services.
Accomplishments
In 2017, the program completed construction of the Westlands Park (Parkside Pond) outlet repairs, the emergency
sinkhole repair at Syracuse and Greenwood Plaza Boulevard, and continued maintenance activities at Greenwood
Gulch from Holly to the Highline Canal. Dissolution of the Greenwood Village Sewer General Improvement District No.
1 (GID) was finalized, with all GID assets and maintenance responsibilities being transferred to Southgate Sanitation
District. Staff oversaw the undergrounding of utilities along Orchard Road in partnership with Centennial, and formalized
the scope of the Cherry Creek Village North utility undergrounding project. Design of the Goldsmith Gulch – Orchard
Road at Silo Park Culvert Replacement Project commenced, and design for Greenwood Gulch – Holly to High Line
Canal Drainage Improvement Project, and the Bridgewater Ponds Improvement Projects were completed. Design of
the Belleview Avenue and Clarkson Street Drainage Improvements Project was also completed after a delay due to
utility conflicts. Due to CDOT permitting requirements, construction of the project will be delayed until 2018. Staff
continued to implement changes associated with the new MS4 permit and implemented the first phase of a new asset
management system for Public Works and Parks, Trails and Recreation. Staff continued to evaluate the benefits of the
automatic vehicle locating system for sweeping operations. The Goldsmith Gulch Master Drainage Plan and Flood
Hazard Area Delineation (FHAD) Update was started during 2017, in partnership with the Urban Drainage & Flood
Control District UDFCD).
Goals/Objectives
In 2018, the program plans to complete the following:
Construction of the Greenwood Gulch – Holly to High Line Canal Drainage Improvements (in partnership with
UDFCD). This includes removal and replacement of the low-flow trail crossing located near the midpoint of
Greenwood Gulch between Holly and the High Line Canal and reestablishing the low-flow channel through the
reach.
Complete design of Goldsmith Gulch – Orchard Road at Silo Park Culvert Replacement Project (in partnership
with UDFCD). The project will improve drainage under Orchard Road to prevent overtopping in extreme
weather events.
Construction of the Bridgewater Ponds Improvement Project. The project will increase the conveyance of the
channel between the two ponds, remove two buildings from the floodplain, and provide water quality facilities
for a portion of the Arapahoe and I-25 construction project.
Construction of the Belleview Avenue and Clarkson Street Drainage Improvements.
Completion of the Goldsmith Gulch Master Drainage Plan and FHAD Update (in partnership with UDFCD).
