Lower Lakeview and Hunter/Rosewood Drainage Improvements

Project Scope/Background

This project includes stormwater drainage improvements on the following streets:

  • Lakeview Boulevard (between approximately 6077 Lakeview Blvd to 6333 Lakeview Blvd),
  • A one (1)-block area at 17607 Pilkington Road,
  • Hunter Court, and
  • Rosewood Street, from Hunter Court to Mandi Lane.

The project will focus on decommissioning drywells, constructing new public rain gardens or stormwater planters where feasible in the right-of-way, and installing stormwater pipe.

  • Lower Lakeview Boulevard currently has little to no stormwater infrastructure or treatment facilities to reduce the amount of runoff experienced in the area. This project will decommission three drywells and provide the beginnings of a public stormwater system, treat stormwater, and improve drainage in the area of Lakeview Boulevard, between 6077 Lakeview Blvd and 6333 Lakeview Blvd. This project is required for compliance with the City's Underground Injection Control (UIC) Stormwater Permit. 
  • The Hunter Court/Rosewood Street area currently has infiltration trenches, which are planned to be removed and replaced with new public rain gardens or stormwater planters where feasible in the right-of-way.
  • The Pilkington Road portion of this project involves decommissioning a drywell and connection to the public stormwater system in Pilkington Road.

Schedule

  • Design – 2024
  • Construction – summer 2025

These schedules are subject to change.

Project Updates

August 2024

Starting the week of August 5, underground utilities will be marked in the City’s right-of-way so the design team can begin their work which will consist of a topographic survey, arborist report, infiltration testing, drilling boreholes, and geotechnical investigation efforts. Crews may be taking photos, surveying elevations of the area, and locating utilities, mapping and assessing tree health, conducting soil sampling, and gathering other information to inform design and future construction. Most of the preliminary work is expected to take a few months to complete, although some follow-up visits through the fall may be needed.

Neighbors may notice the following:

  • Underground utilities will be marked on the street with paint. Paint marks will disappear over time.
  • Survey crews will be conducting field work predominantly in the public right-of-way but may need to verify property corners and monument markers at times.
  • A few intermittent lane closures may occur during the daytime while crews conduct infiltration testing, soil sampling, and surveying. Flaggers or signage will direct drivers or assist local neighbors with access.  Please watch for drilling equipment and workers.
  • Trees may be flagged during survey work. We will minimize the impact to large trees when feasible and have an arborist on the design team.
  • Wooden stakes with flags may remain in the project area until construction begins in summer 2025. They are left to indicate the public right-of-way, utility conflicts, or other construction considerations. Please do not remove or adjust the stakes.
