About the Project
The City of Commerce City is proposing improvements to E. 88th Avenue between I-76 and Highway 2. The City has conducted an Environmental Assessment (EA) along this 1.6-mile stretch.
The purpose of the E. 88th Avenue project is to improve traffic operations and accommodate current and future general vehicular traffic, heavy trucks, bicycles, and pedestrians on E. 88th Avenue between I-76 and Highway 2.
Need 1: Improve roadway operations
Need 2: Accomodate all users
What is an Environmental Assessment?
An Environmental Assessment, required by the National Environmental Policy Act (NEPA), is a concise document prepared to identify both positive and negative impacts related to a project. During NEPA, impacts to community and natural resources are assessed. Impacts to the community focus on land use patterns, the socioeconomics of those affected, noise, effects to historic resources, and more. Natural resources include wetlands, air quality, wildlife, water quality, and others. Impacts to these environmental resources are assessed to avoid, minimize and mitigate possible negative impacts.

Project Study Area
Under the National Environmental Policy Act (NEPA), an Environmental Assessment determines the impacts of a project. The project study area includes areas of both permanent (direct and indirect) impacts from the completed project and temporary impacts during construction. The No-Action and Proposed Action Alternatives were evaluated for impacts to environmental resources within the project study area.
What is the Project (Proposed Action)?
Multiple design options were developed and evaluated for six design elements within the project study area. Stakeholder and public input was considered during this evaluation process. Additional information regarding the Design Options Evaluation Process can be found in the Design Options Screening Report.
The Proposed Action is the alternative that resulted from combining the selected design options. The Proposed Action was evaluated through Preliminary Design and the Environmental Assessment.

- Improved Jolene Court approach to Brighton Road.
- Permitted U-turn at E. 88th Avenue and Brighton Road.
- Improved access at the Mile High Flea Market with a signalized intersection, dedicated left-turn and U-turn movements, and dynamic lane (left-turn lane during events and travel lane during normal roadway operations).
Proposed Action & Preliminary Design
Based on our research of existing conditions and feedback we received from the community, we have developed the preliminary design below. The preliminary design is available in Appendix D of the Environmental Assessment.

Impacts caused by the Proposed Action can occur on a temporary basis, during construction, or they can occur on a permanent basis, during operation. Impacts can have a negative effect on a resource or a beneficial effect on a resource. Summary information about impacts and mitigation can be accessed by clicking on each resource, below. Additional information about impacts and mitigation can be found in the Environmental Assessment.
