Malibu Lagoon State Beach
Coastal Geomorphology and
Hydrology Study
Date Issued: July 19, 2019
Date Due: September 5, 2019
Malibu Lagoon State Beach Coastal Geomorphology and Hydrology Study
1. Introduction
The City of Malibu is seeking proposals from qualified firms to develop a coastal geomorphology
and hydrology model, and to prepare a study of sediment, erosion, and water resource management
alternatives for public lands at Malibu Lagoon State Beach and the surrounding coastline.
1.1 City Information
The City of Malibu (City) is a coastal city located in the northwestern portion of Los Angeles
County, California with a population of approximately 13,000. The City was incorporated in
1991, operates under the Council-Manager form of government and is considered a contract
city. The five members of the City Council are elected at-large and serve staggered four-year
terms, with the Mayor being selected from among the Councilmembers.
The City covers approximately 21 miles along the coast and offers a full range of municipal
services. The City has 83 full-time employees and 13.5 full-time equivalent part-time
employees. The City’s seven (7) departments provide a number of in-house services, including
management and administrative services, building safety, community services, environmental
sustainability, planning, public works and engineering. Police and fire services are provided
via contract with the County of Los Angeles (County). Other services, such as the City
Attorney, water, street maintenance and garbage collection services are also provided via
contract or by the County. The City’s Adopted Fiscal Year 2019-2020 General Fund Budget
is $37.4 million and the City’s Overall Budget is $55.1 million.
The City is home to several popular public beaches all owned and operated by either the
County Department of Beaches and Harbors (DBH) or the California Department of Parks
and Recreation (DPR).
1.2 Malibu Lagoon State Beach
Malibu Lagoon State Beach is located where Malibu Creek meets the Pacific Ocean in the
City of Malibu and is owned and operated by DPR. Malibu Lagoon State Beach includes the
Adamson House, Malibu Lagoon and Malibu Pier. County DBH owns and operates Surfrider
Beach.
Malibu Lagoon is a 31-acre shallow water embayment occurring at the terminus of the Malibu
Creek Watershed, the second largest watershed draining into the Santa Monica Bay. Malibu
Lagoon is a resting and feeding estuary for more than 200 species of migrating and native
birds, including California least tern and western snowy plover, both federally-listed
Recycled Paper
endangered species. Federally endangered tidewater goby and southern steelhead trout also
inhabit the lagoon, which receives year-round freshwater from sources upstream. Historically,
the lagoon has periodically breached in a number of locations. Malibu Creek and Lagoon
empty into the Pacific Ocean at Malibu Lagoon State Beach and Surfrider Beach, home to
iconic surf breaks and popularized by surfing movies in the 1950s and 1960s. Surfrider Beach
is a popular surfing and recreational destination operated by DBH that receives millions of
visitors every year.
The Adamson House at Malibu Lagoon State Beach overlooks the Malibu Pier and Surfrider
Beach. This Spanish colonial revival home was designed by Stiles O. Clements in 1929 for
Merritt Huntley Adamson and Rhoda Rindge Adamson and is operated as a museum
showcasing historical Malibu artifacts. The Adamson House is a California Historical
Landmark and is also listed on the National Register of Historic Places. The Malibu Lagoon
Museum, which adjoins the Adamson House, displays the history of the area from the days of
the Chumash tribe, to the gentlemen ranchers, and finally to the birth of the surfing era. On
the east side of Malibu Creek Bridge, the famous Malibu Pier allows for excellent saltwater
fishing. On the west side of Malibu Creek Bridge, visitors will find picnic tables and a nature
area, excellent for birdwatching and the study of a unique eco-system, one of few remaining
examples in Southern California of a seasonally closed estuary (bar-built estuary).
In 2010, Surfrider Beach was declared the first-ever World Surfing Reserve by the non-
governmental organization Save the Waves Coalition aimed at protecting global surf habitats.
In 2018, a 160-acre area composed of public property, including the First Point, Second Point,
and Third Point surf breaks, Malibu Pier, and portions of Surfrider Beach and Malibu Lagoon
State Beach, was designated as the Malibu Historic District and listed on the National Register
of Historic Places.
Currently, this area of eastern Malibu has three periods of California's cultural history
represented in the National Register: the Chumash Humaliwo village site, Stiles O. Clements'
Adamson House, and the Malibu Historic District.
1.3 Malibu Lagoon Restoration
In 2013, DPR completed an extensive restoration and enhancement project of Malibu Lagoon.
The project involved excavation and reconfiguration of previously manufactured channels on
12 acres in the western half of the Lagoon and the subsequent planting of native wetland
vegetation. Post-construction monitoring was conducted by The Bay Foundation in
accordance with the “Malibu Lagoon Restoration and Enhancement Plan, Hydrologic and
Biological Monitoring Plan” and the “Malibu Lagoon Plant Communities Restoration,
Monitoring, and Reporting Plan,” which each specify hydrologic and biological monitoring

protocols and procedures for conducting monitoring before, during, and after the Project.
Copies of the reports are available on The Bay Foundation website at:
https://www.santamonicabay.org/explore/library/reports/.
1.4 Project Objective
In recent years, Surfrider Beach and the Adamson House property have experienced
significant sand erosion. The specific cause of the sand erosion is unknown; however, the sand
erosion has been particularly pronounced over the past year. As a result, the City is seeking
proposals to develop a model to inform alternatives and management actions that address
water resources, coastal erosion, sediment deposition and beach nourishment.
The City is seeking a qualified consulting firm to develop a coastal geomorphology and
hydrology model, and to prepare a study of sediment erosion and water resource management
alternatives that will increase public land managers’ understanding and potential responses to
the hydrology/sedimentation/geomorphic processes affecting Malibu Lagoon State Beach and
the surrounding coastline. The model will provide new capabilities to evaluate the
effectiveness of various alternative management actions for coastal resources at Malibu
Lagoon State Beach. The selected firm will also prepare a Coastal Geomorphology and
Hydrology Study. The primary objective to be served by the model and study is to develop
management alternatives to address coastal erosion, sediment deposition, and beach
nourishment at Malibu Lagoon State Beach and the nearby coastline. One or more preferred
management alternatives could eventually be incorporated into a Lagoon Management Plan,
which is not a part of this scope of work.
The City is located within the California coastal zone and, as such, is subject to the regulations
of the City’s Local Coastal Program (LCP). The Malibu LCP was certified by the California
Coastal Commission (CCC) in 2002. Section 9.32 of the LCP Land Use Plan states that the
City can establish a Lagoon Management Plan through a Local Coastal Program Amendment
(LCPA). All LCPAs must first be certified by the CCC before taking effect. In order for the
City to develop a Lagoon Management Plan, DPR, DBH and the State Historic Preservation
Officer would have to be consulted regarding any potential management techniques that might
be proposed for Malibu Lagoon.
1.5 Minimum Firm Qualifications
The City is seeking a consulting firm (or team of consultants) who has:
A working knowledge of the requirements of the California Coastal Act related to
the preparation of LCP’s

coastline, and prepare a coastal geomorphology and hydrology study to inform alternatives for
potential management actions to address local coastal erosion, sediment deposition and beach
nourishment. Project tasks and deliverables are described below. [Note: In the proposal, consultant
may reorganize these tasks and deliverables to suit a preferred approach to performing the work.]
Task 1 – Existing and Historical Conditions Assessment
As a basis for developing the modeling tools, the consultant shall provide an assessment of
existing and historical conditions, including: sediment transport and movement within the
littoral cell; sediment movement restrictions along the coastline (e.g., jetties, seawalls); and
upstream barriers. For the Existing Conditions Assessment, the consultant will:
Study historical coastline, lagoon configurations, upcoast sediment input to the
Malibu coastline littoral cell, and how those have changed over time
