E Avenue Drainage Improvements

Project Scope/Background

E Avenue currently has little to no stormwater infrastructure or treatment facilities to reduce the amount of runoff experienced in the area. This project will provide the beginnings of a public stormwater system, provide treatment of stormwater, and improve drainage in the area of E Avenue, between 2nd and 4th Street.

The project will focus on installing new public rain gardens or stormwater planters where feasible in the right-of-way.


  • Design – 2024
  • Construction – spring – summer 2025

These schedules are subject to change.

April 2024: Preliminary Work Starting Soon

In the coming weeks, underground utilities will be marked in the City’s right-of-way so the design team can begin with their initial survey, infiltration testing, and geotechnical investigation efforts. Crews may be taking photos, surveying the area for elevation and locations of utilities, mapping and assessing the health of trees, undertaking geotechnical investigations, and gathering other information to inform the early stages of design work and future construction. Most of the preliminary work is expected to take a few months to complete, although some follow-up visits throughout 2024 may be needed.

Neighbors may notice the following:

  • Survey crews will be conducting field work predominantly in the public right-of-way, but at times, may need to verify property corners and monument markers.
  • A few intermittent lane closures may occur during the daytime while crews conduct infiltration testing and surveying. Flaggers or signage will direct drivers or assist local neighbors with access.
  • Trees may be flagged during survey work. We will be looking at how to minimize impact to trees and will have an arborist working with the team.
  • Underground utilities will be marked on the street with paint. Paint marks will disappear over time.
  • Wooden stakes with flags might be left at some places along the project area. These may indicate the public right-of-way, drainage issues, or other considerations. Please do not remove or adjust the stakes.
