New Phase of Improvements to Begin at Colorado Lagoon
2016-09-19 · By Editor
The improvements at Colorado Lagoon will continue next week with a new phase to create additional ecological resources for aquatic life as well as birds.
“The Colorado Lagoon is a huge success story,” said Mayor Robert Garcia. “We have greatly improved the water quality, and we are continuing to restore it as a unique natural gem in Long Beach.”
Crews will dredge and move sediment from the central basin to the north arm of the lagoon, near Monrovia Avenue, where the water will become shallower. This will facilitate the hydrological conditions for eelgrass, salt marsh, sage scrub and freshwater plants to grow, which will greatly enhance the ecological value of the Lagoon. The creation of new intertidal and shallow subtidal habitat and eelgrass beds will provide foraging for local birds at one of Southern California’s last remaining coastal lagoons.
“This phase of the restoration will build on years of hard work and continue to help realize the community’s vision for a clean, healthy, and accessible Lagoon that will support a diverse range of aquatic plants and animal communities,” said Councilwoman Suzie Price.
Construction activities will begin on Monday, September 19. The playgrounds and picnic areas at the Colorado Lagoon will remain open, but access to the water will be closed during construction, which is expected to last until early 2017.
Other improvements will include:
- Replacing the asphalt road with a vegetated bioswale and pedestrian trail
- Extending the floating pier and footbridge to span the expanded subtidal areas
- Adding 16 new piles to support the structure
- Repainting the pier replacing the stairs with ADA-compliant ramps
- Installing pedestrian amenities such as log seating, benches, bike racks and interpretative signage
Previous restoration activities have vastly improved the water quality. Low flow diversion systems and trash capture devices continue to prevent new contaminants and debris from entering the Colorado Lagoon, and contamination has been removed from the Lagoon bottom.
The transformation of the Colorado Lagoon has been possible thanks to the support of local residents, and the partnership and collaboration with the Friends of Colorado Lagoon, and State and Federal agencies.
