A true Conservationist is a man who knows that the world is not given by his fathers, but borrowed from his children.

Program EIR for the updated Los Peñasquitos Lagoon Enhancement Plan

A program-level Environmental Impact Report (EIR) has been prepared for the updated Los Peñasquitos Lagoon Enhancement Plan (Lagoon Enhancement Plan) for compliance under the California Environmental Quality Act (CEQA).  The EIR is the first step in environmental review of key project concepts identified in the Lagoon Enhancement Plan and provides preliminary impact analysis, development of impact avoidance strategies, and identification of mitigation measures where impacts cannot be avoided.  With certification under CEQA expected by the end of 2020, this EIR will serve as a framework to guide and expedite project-level design and environmental review for large-scale restoration and enhancement of the Lagoon’s native habitats, as well as improvements to public access and vector management.

A Notice of Availability (NOA) and the Draft EIR are currently available for public review and comment for a 45-day period.  Please look at the NOA for pertinent information that includes: identification of the Lead Agency, start and end dates of the public comment period, how and where to submit comments, and the date/time for a virtual public meeting to present the EIR and address questions related to the EIR and CEQA process.  Once comments are received, a Final EIR will be prepared, completed and certified with the State of California.

An open meeting will be held via Zoom on December 12 from 10:00 am – 11:30 pm to provide members of the public an opportunity to get a better understanding of the Draft Los Peñasquitos Lagoon Program EIR during the comment period that ends December 28, 2020.  A presentation will be given that will provide a summary of the project background, proposed project, summary of impact threshold analysis, how to submit formal comments and expected release of the of the Final EIR.   Please note that formal comments will not be taken at this meeting and must be submitted directly to California State Parks (Lead Agency) in writing as described in the NOA (see previous paragraph).  Meeting agenda with Zoom information can be downloaded by clicking the following link:  PEIR Public Meeting Agenda (12.12.2020)


  • Los Peñasquitos Lagoon is a dedicated State Marsh Natural Preserve, affording it the highest level of protection within California.
  • Los Peñasquitos Lagoon is a 565-acre coastal estuary that evolved from a large, depositional river valley with fringing marsh. The Lagoon receives drainage from an approximately 59,212-acre watershed comprised of three primary sub-drainages: Carmel Valley, Los Peñasquitos Canyon and Carroll Canyon.
  • Los Peñasquitos Lagoon and its adjacent uplands are home to at least 48 sensitive species that include 35 plants, 1 insect, 5 reptiles, and 7 birds.
  • Los Peñasquitos Lagoon also serves as an important refuge for migratory birds using the Pacific Flyway and is the closest coastal estuary providing essential fish habitat to support the La Jolla State Marine Conservation Area (ASBS #29) and San Diego-Scripps State Marine Conservation Area (ASBS #31) located just south of the Lagoon.
