Romtec Utilities designed and supplied a development stormwater pump station for a new mixed-use development in Gresham, Oregon. The low-flow pump station manages site runoff, supports construction sequencing, and provides permanent drainage infrastructure for the Cedarline Apartments project.

Located near the Gresham Central Transit Center, the pump station serves a mixed-use development associated with Level Development’s Cedarline Apartments project. The development includes multifamily housing and ground-floor commercial space, so the site needed a drainage solution that could support active construction and long-term operation.

Downtown Gresham continues to see investment in housing and mixed-use projects that take advantage of transit access and walkable neighborhoods. The project site is adjacent to the MAX light rail line and within walking distance of retail, restaurants, schools, and community services.

The Cedarline Apartments development combines multifamily housing with ground-floor commercial space, adding new residential and commercial activity to the downtown area. Like many urban infill projects, the site required carefully planned drainage infrastructure before construction could move forward.

Installing the stormwater pump station early allowed other phases of the development to proceed.

Urban development increases stormwater runoff from impervious surfaces such as roofs, sidewalks, parking areas, and drive aisles. A reliable development stormwater pump station collects and conveys this runoff when gravity drainage cannot move water effectively.

For the Cedarline Apartments project, site conditions made gravity drainage impractical. The development team needed a dedicated stormwater pumping system that could move runoff from the site and meet the hydraulic requirements established by the project engineers.

The design requirements included:

• Peak inflow of approximately 88 gallons per minute
• Low-flow discharge conditions
• Limited available site space
• Coordination with future building foundations
• Connection to the planned drainage system

Because the pump station would be installed within an active development site, the drainage solution needed to be coordinated with the overall construction sequence.

Romtec Utilities worked with BKF Engineers during early planning to develop a stormwater pump station design that matched the site’s drainage needs, available space, and construction timeline.

The completed system uses a compact wet well and pump configuration designed for the Cedarline Apartments development. Instead of serving a broad municipal drainage area, this low-flow stormwater pump station manages runoff for one mixed-use development.

Key design features include:

• Low-flow stormwater pumping configuration
• Compact wet well design
• Dual force main arrangement
• Stormwater discharge piping
• Three-phase electrical service
• Site-specific hydraulic design

By providing design information early in the project, Romtec Utilities helped incorporate the pump station requirements into the construction documents and coordinate the system with the larger development plan.

The stormwater pump station also played an important role in the project’s construction sequence.

Because portions of the development depended on completed drainage infrastructure, installation of the pump station became an early project milestone. Completing this work allowed construction of other site improvements and building foundations to move forward.

This type of coordination is common on urban infill projects where utilities, buildings, and limited site space must be carefully planned.

Once construction is complete, the station will manage runoff generated by the finished development and remain part of the site’s permanent drainage system.

The project advanced quickly as the development team worked to meet an aggressive construction schedule.

BKF Engineers contacted Romtec Utilities during early design for stormwater pump station support. Romtec Utilities developed preliminary engineering information on an accelerated timeline so the team could include the pump station in the construction documents. After bidding, Romtec Utilities partnered with Konell Construction to deliver the system.

Throughout the process, close coordination between the design and construction teams helped keep the project moving forward.

Several organizations collaborated on this project:

• End Owner: Level Development
• Civil Engineer: BKF Engineers
• General Contractor: Lease Crutcher Lewis
• Installing Contractor: Konell Construction
• Stormwater Pump Station Provider: Romtec Utilities

Together, these organizations coordinated the design and construction of the stormwater pump station serving the Cedarline Apartments development.

The development stormwater pump station for the Cedarline Apartments project provides essential drainage infrastructure for one of downtown Gresham’s new mixed-use developments. Romtec Utilities engineered the system for low-flow stormwater conditions, a compact site footprint, and the project’s construction schedule.

By working with Level Development, BKF Engineers, Lease Crutcher Lewis, and Konell Construction, Romtec Utilities delivered a site-specific stormwater pump station that supports construction and long-term operation. For developers, engineers, and contractors planning urban stormwater infrastructure, Romtec Utilities can design and supply a pump station that fits the site, schedule, and hydraulic requirements.
