Echo Park Lake Project Concepts

During the project’s early stages, some preliminary design concepts and approaches are being explored. These will be refined as more data is received during site research.

In-Lake Basin Improvements

Removing contaminated sediments after draining the lake, replacing the lake liner, re-configuring storm drain inlets, and a variety of improvements ranging from filters to aeration.

In-Lake Vegetation and Habitat Improvements

Reconditioning the famous lotus beds, as well as making improvements to existing floating wetland islands and shorelines of the lake.

Parkland Structural Best Management Practices (BMPs)

Adding grassy swales, porous pavement, weather-based irrigation systems, and educational signage and kiosks.

Project Concepts
Roll your mouse over the targets in the photo below to see some of the concepts that are being evaluated.

Under drainage directed into the lake will improve water quality and reduce peak flows while enhancing aesthetics. Vehicular access, sweeping and sub-drainage will be addressed early.
A treatment train consisting of below grade trash removal devices followed by a constructed wetland treatment area is proposed to not only provide pollutant reduction but to significantly improve the aesthetics of the area.
The beds are very important to the community. The restoration plan will be developed by a recognized expert and special attention will be paid to timing, storage and protecting the tubers during construction and requirements for post construction monitoring.
By lining the lake and providing significant water quality improvements to the inflows draining into the lake, potable water use will be minimized.
In lake water quality improvements will be evaluated on a review modeling results, a clear understanding of lake management practices and the recommended treatment regimes for flows into the lake.
The performance of the existing floating islands will be evaluated in conjunction with the plans for waterfowl management before concepts are developed for the new floating islands.
Proper management of the sediment is critical to project success. Sampling is the first step in this process..
The existing outlet area will be evaluated to better assess its condition.
In areas of grade separation, retaining walls will be utilized in conjunction with grassy swales and infiltration strips to reduce sediment and nutrient loads from local runoff. Opportunities for enhancing public enjoyment will be developed.
Neighbor friendly options for lining the lake will be considered that will save potable water use and save over $18 million in construction costs.
