1.1 Master Plan Scope of Work

Chapter 1 – Executive SummarySLRCMP: Stakeholder Working Group Meeting #8

The Silver Lake Reservoir Complex was removed from the City’s drinking water supply system in 2008 and is being repurposed as a passive public park.

The Silver Lake Reservoir Complex Master Plan (herein referred to as the “Master Plan”) provides a bold vision for a new 116-acre park that will blend urban wilderness with community park amenities.

1.3 Project Overview


The Master Plan initiative was undertaken to allow the Silver Lake community and City of Los Angeles to consider repurposing this major piece of urban infrastructure for public use. The Master Plan project originated March 29, 2018, when the City Council approved a Memorandum of Agreement between the Bureau of Engineering (BOE) and the LADWP where BOE began the SLRCMP processes funded by LADWP.

The agreement included LADWP continuing their operational responsibilities, such as the maintaining integrity of the dams and LADWP onsite facilities.

1.4 Vision & Goals


As wildlife habitat continues to disappear in our increasingly urbanized world, introducing wildlife habitat back into cities is becoming ever more important. Early in the community engagement process, enhancing and expanding habitat for wildlife was identified as a primary goal for the Master Plan. The Park is envisioned as a hybrid space that unleashes the power of natural processes and human connection.

The Design Team’s goals listed below guided the development of the Master Plan:

• Create a clear, bold design that repurposes the Silver Lake Reservoir Complex to a public park• Preserve and enhance the unique character of the Silver Lake Reservoir Complex• Create a public amenity with safe and varied access• Balance active and passive uses• Balance wildlife habitat with human uses • Create a design that is implementable and can be partially funded through grants• Allow for continued LADWP on-going operations and future use and access

A year-long community process included five large community workshops and eight focused meetings with the Stakeholder Working Group to garner public feedback at all critical stages in the planning process: analysis, visioning and programming, Master Plan Alternatives, and Preferred Master Plan

The Master Plan reflects the vision and interests of the community who live near the Complex and visit it frequently.

Community Workshops were attended by 1,570 community members and generated more than 7,500 questionnaire responses.

1.5 Community-Based Planning Process


ROUP PURPOSES ONLY

26


The Silver Lake Reservoir Complex is conceived as a hybrid infrastructure that amplifies the use of a water body to attract and sustain wildlife, connect with nature and neighbors, and educate.

The Park will feature two flexible lawns with shade trees, a picnic grove and ornamental gardens with informal play area, and an education center along the east edge of Silver Lake Reservoir. At the intersection between the lawns and the water, stepped seating terraces give way to wetland terraces interwoven with small footpaths. Extending from the woodland habitats of the Knoll and Eucalyptus Grove is a new ecosystem that reintroduces coastal scrub and wetland habitat to the Complex for the first time in over 100 years. This rich tapestry of spaces is stitched together by the Promenade, a 2.5-mile loop around the inside of the reservoirs.

1.6 Master Plan Overview


ROUP PURPOSES ONLY

27


The Master Plan design is founded on principals of sustainability, interweaving systems of ecology, water, and education cohesively. These visible forms of sustainability make the Silver Lake neighborhood and the City of Los Angeles leaders in freshwater resource management and stewards of urban wildlife.

The design of the Silver Lake Reservoir Complex incorporates habitat enhancement and expansion that emphasizes re-establishing wetlands at the site, a water management strategy that supports a healthy aquatic ecosystem, and an education facility with features that engage the community and teach residents, especially youth, about wildlife stewardship and climate adaptation.

Key Indicators:Too much causes algae to grow faster than ecosystems can handle.

Too much causes algae to grow faster than ecosystems can handle.

The concentration of chlorophyll a present in the water is directly related to the amount of algae living in the water.

Excessive growth of these organisms, in turn, can clog water intakes, use up dissolved oxygen as they decompose, block light to deeper waters, and can cause water to become toxic.
