Berkshire Creek

The Project

It's a quiet little canyon in the southwest corner of Hahamongna Watershed Park that has been degraded over the years by flooding and erosion. The Berkshire Creek Area Improvement Project is an Urban Streams Restoration program that will upgrade habitat, improve public safety and restore more natural hydrology to Berkshire Creek.

The Arroyo Seco Foundation is pleased to co-sponsor this program with the City of Pasadena. Psomas is the Environmental Consultant.

March 18, 2020 — Pasadena has now filed the notice of completion for the Berkshire Creek restoration project in Hahamongna Watershed Park. Design, permitting and construction have all been completed in a whirlwind 15 month period, a tribute to project manager Brent Maue and all the community support for the program.

The recent rains have demonstrated how remarkably well the project works to restore the stream and to provide improved flood protection and recreational opportunity while preventing erosion.

It's a sign of good things to come for Hahamongna and the Arroyo Seco.
