Penn Avenue/Eastwood Drive Improvements Prescott Civil Engineering Project

Engineering Community Connections: Upgrading Penn Avenue and Eastwood Drive

Civil engineering firm granite basin working on Penn Ave., Eastwood Drive project

As part of historic Prescott, the Penn Avenue/Eastwood Drive Improvements project is an example of Granite Basin Engineering's expertise in urban infrastructure rehabilitation. This $11 million capital improvement project showcases our ability to solve complex drainage issues while enhancing transportation infrastructure. The project transformed an area with aging infrastructure into a thriving community destination utilizing the Acker Park recreation area.

The Challenge

Prescott's historic Penn Avenue and Eastwood Drive had deteriorated roadways and significant drainage problems, leading to flooding and safety concerns for both pedestrians and motorists. Our task was to overhaul the area's infrastructure while preserving its character and minimizing disruption to residents.

Our Approach


Granite Basin Engineering developed a comprehensive solution:

  • Drainage Overhaul: We designed a 16 acre-foot multi-use regional detention basin to manage stormwater effectively.
  • Road Improvements: The project included upgrading the roadways to enhance safety and traffic flow.
  • Utility Updates: We coordinated the modernization of underground utilities.
  • Recreational Improvements: We developed a new trailhead with access to Acker Park.
  • Community Engagement: Our team worked closely with over 100 property owners to secure necessary easements.

Technical Highlights

  • 16 acre-foot regional detention basin
  • Installation of large culvert crossings
  • Implementation of curbed roadways with storm drains
  • Design of open channels for improved water flow
  • Implementation of new recreational facilities and walking trails

The Result

The completed Penn Avenue/Eastwood Drive project has dramatically improved flood control in the area while providing smoother, safer roads for Prescott residents. The multi-use detention basin not only manages stormwater but also serves as a community asset, including walking paths and trailheads.


This project demonstrates Granite Basin Engineering's ability to tackle urban infrastructure challenges, balancing technical requirements with community needs. It's a testament to our commitment to creating lasting, multi-functional solutions that serve the community for years to come.
