County "Overlap" Prompts Pasadena to Launch New Hahamongna Restoration Projects

Change in description creates additional restoration areas outside of Los Angeles County sediment removal project area

A portion of the Los Angeles County Devil's Gate Reservoir Sediment Removal work area now encompasses a previously planned Pasadena restoration project area. Pasadena's City Council approved moving municipal work to new areas.

The Oak Grove Area of Hahamongna will likely see an increased amount of habitat restoration over the next few months after Pasadena’s City Council approved a Public Works proposal Monday.

This outcome resulted from recognizing some areas in Hahamongna Watershed which were part of Pasadena’s “Oak Grove Improvement Project” are now contained within the scope of the Los Angeles County Devil’s Gate Reservoir Sediment Removal project.

Essentially, the County’s plan overlaps the City’s work, so the Pasadena’s Public Works will create a series of additional, new habitat restoration areas to the north of the County project.

The City of Pasadena decided to move restoration projects now inside the Los Angeles County Devil's Gate Reservoir Sediment Removal work area to new locations not previously slated for habitat restoration.'

The new project will remove the non-native and invasive species and plants, and replace them with local native species, as well as provide additional maintenance and management, Pluth explained.

“This will give the native species a toehold,” explained Pluth, “and an opportunity to thrive and compete against the non-native species.”

“This is good news,” said Mayor Terry Tornek. “This is additional restoration work.”

In order to accurately reflect the changes, the Department of Public Works proposed a revision Monday to the Habitat Restoration Capital Improvements Project description to reflect the new immediate habitat restoration effort.

This would allow the implementation of the habitat restoration project and the related expenditure of grant funds to proceed.

The County’s mitigation work removes the ability for the City to perform restoration inside the Devil’s Gate Reservoir Sediment Removal project area, the staff report said.

The new recommended revision to the adopted habitat restoration project description will now read:

‘This project provides for riparian and woodland habitat restoration associated with the improvements to the east of the West Rim Trail and the ramped trails connecting the West Rim Trail to the Basin Perimeter Trail and habitat restoration associated with adjacent to the Berkshire Creek project. “

As Public Works Director Ara Maloyan noted, the habitat restoration project is funded by a State Proposition 12 grant, and due to a June 30, 2019 project grant deadline, must be implemented by March 31, 2019.

In order to comply with that schedule, the City must proceed with the habitat restoration project “independent of the Berkshire Creek and Trail Development projects, and in areas outside those project footprints and the County’s restoration area,” said Loren Pluth, the City’s project manager for parks and landscaping,
