Review of the Coryell Ranch Site Application for
expansion of a lift station
Coryell Ranch Company, LLC
PROJECT INFORMATION AND STAFF COMMENTS
il.
A.
The applicants are proposing to build the Coryell Ranch Lift Station to meet the Coryell
Ranch PUD sewage treatment needs. The lift station will provide access to the sewage
lines in the Aspen Glen PUD and ultimately, the Roaring Fork Water and Sanitation
District treatment facilities. Coryell Ranch PUD is projected to have population
equivalent of 288 people or 72 EQR's. At build out, the lift station is projected to have
a loading of 28,800 gpd at average daily flow andl2,000 gpd at maximum daily flow'
The lift station will be located at the northerly edge of the Coryell Ranch PUD, with a 4'
force main crossing under the Roaring Fork River and tie into an exiting manhole within
the Aspen Glen PUD. The lift station will consist of a wet welUdry well configuration,
with two sewage pumps, each producing a flow of 150 gpm. All of the sewage from the
Coryell Ranch PIID will be via gravity flow to the lift station.
Issues and Concerns
Legal Process: To build a new lift station, an applicant is required to submit an
Application for Site Approval for Waste Water Treatment Facilities to the Colorado
Department of Public Health and Environment (CDPHE). The site application is
required to be reviewed by the County Board of Health, Board of County Commissioners
and Planning Authority. These entities are given three recommendation options;
approval, disapproval and no comment. The recommendation is to address the following
questions:
"Are the proposed facilities consistent with the comprehensive plan and any other plans
for the area, including the 201 Facility Plan or 208 Water Quality Management Plan, as
they affect water quality?"

The recommendations made by local governments are considered by the CDPFIE in their
approval or denial of the site application. If the CDPfm recommends denial of the
proposed site application, it can be appealed to the Colorado Water Quality Control
Commission.
B. Garfield County Comprehensive Plan: The Roaring Fork Water and Sanitation District
wastewater treatment facility is located in an area shown as 'oExisting Subdivision" on the
Garfield County Comprehensive Plan of 1995 - Study Area I, Proposed Land Use
Districts Map. This designation is acknowledgment of the approval of the Aspen Glen
PUD. The following are some relevant Comprehensive Plan goals, objectives and
policies.
Water and Sewer Services
Goal: To ensure the provision of legal, adequate, dependable, cost effective and
environmentally sound sewer and water service for new developments.
Objective 7.5: Garfield County will strongly discourage the unnecessary
proliferation of private water and sewer systems.
Policy 7.1: All development proposals in rural areas without existing central
water and./or sewer systems will be required to show legal, adequate, dependable
and environmentally sound water and sewage disposal facilities can be provided
before proj ect approval.
Policy I .2: Where logical, legal and economic extension of service lines from an
existing water and/or sewage system can occur, the will require development
adjacent to or within a reasonable distance to enter into the appropriate agreement
to receive service. The burden of proof regarding logical, legal and economic
constraints will be on the developer.
Policy 7.4: Where I.S.D.S. is not feasible, Garfield will require a sewage disposal
system approved by the State of Colorado.
Comment: The Roaring Fork Water and Sanitation District was designated as a
regional sewage treatment service provider when the system was originally
approved. The Coryell Ranch property was included in the original service area
of the RFWSD and service to the property would be consistent with the Water and
Sewer Services goals and policies.
Natural Environment
Goal: Garfield County will encourage a land use patten which recognizes the
environmental sensitivity of the land, does not overburden the physical capacity
of the land and is in the best interest of the health, safety and welfare of Garfield
County.
.,
Objective 8.4: River-fronts and riparian areas are fragile components of the
ecosystem and these areas require careful review in the planning process.
Policy 8.4: The County will require development with river frontage to address
the issue through physical design in a way which will protect fragile wetlands and
scenic resources and protect flood plains from encroachment.
Comment: The entire project is within the boundaries of the Roaring Fork River
flood plain. It will be necessary for the applicants to obtain a Flood plain Special
Use permit, prior to construction of the new facility. If construction of the facility
is very clearly designed to prevent any flooding potential, the application can be
found to be consistent with the Natural Environment goal and policies.
III. CONCLUSION
The Board of County Commissioners and the Board of Health recommended approval of
the proposed site application with the following comment:
1. That a special use permit for the facility be approved for the placement of the
facility in the flood plain.
