Santa Clara River and Tributaries Physical Map Revision

Description:
BakerAECOM will update the Special Flood Hazard Area associated with the Santa Clara River and select tributaries.
 
In an effort to assist Los Angeles County and incorporated areas in circulating the preliminary data, digital copies of the revised FIRM panels, FIS report, and Digital FIRM database can be accessed on the following website: www.fema.gov/preliminaryfloodhazarddata. For more information on FEMA's Appeal Process and the Summary of Map Actions, please refer to the following hyperlinked resources in FEMA's library:


Open Pacific Coast Study

Description:
The Federal Emergency Management Agency (FEMA) is performing detailed coastal engineering analyses and mapping of the Pacific coast of California. The analysis and mapping will revise and update the flood and wave data for the Los Angeles County Flood Insurance Study report and Flood Insurance Rate Map panels along the open coast. A kick-off meeting was conducted on December 6 and 7, 2011. Materials from this meeting are available from the Project Documents below.


Santa Monica Bay Watershed Discovery

Description:
The Discovery process is the first step in determining whether a RiskMAP project is needed within the Santa Monica Bay Watershed.  The goal of the Discovery process is for FEMA to work more closely with communities and stakeholders to better understand the local flood risk and mitigation efforts and to encourage watershed-wide discussions about increasing resilience to flooding. The information exchanged between FEMA and the community during Discovery will improve our understanding of your flood hazard mapping, flood risk, mitigation planning, and communication needs.
Discovery Meetings for the Santa Monica Bay Watershed were held on the following dates:
  • September 25, 2012 - Calabasas, California
  • September 26, 2012 - Wilmington, California
  • September 26, 2012 - Lawndale, California
  • September 27, 2012 - Los Angeles, California
The final Discovery Report is available in the project documents listed below.

Ballona Creek Physical Map Revision

Description:
BakerAECOM will perform a 2-D flood risk study in the southeastern area of the Ballona Creek watershed, which includes the Park Mesa Heights study area.  The study will incorporate local hydrology data and local storm sewer data.  Preliminary products will be prepared and released for the SE portion of the watershed only.


Las Virgenes Creek and Palos Verdes Estates Map Revision

Description:
This Physical Map Revision (PMR) included updated Zone AE study (without floodway) for Las Virgenes Creek in Calabasas, CA, using locally-available rain gage data.  The PMR also incorporated Zone AE (with floodway) study for 2 miles of unnamed streams within Palos Verdes Estates.

The Letter of Final Determination (LFD) for this PMR was issued on July 6, 2015. The PMR will become effective on January 6, 2016.



Santa Monica Bay Watershed Non-Regulatory Product Development

Description:

​Santa Monica Bay Watershed non-regulatory products include the Flood Risk Database (FRD), Flood Risk Map (FRM), and Flood Risk Report (FRR).  Flooding sources included in the initial version of the Santa Monica Bay Watershed non-regulatory products include the Ballona Creek Watershed, Las Virgenes Creek and Medea Creek.  Products include depth and analysis grids, risk assessment data using the average annualized loss (AAL), areas of mitigation interest (AOMI), and changes since last FIRM (CSLF).

 Flooding sources from the Lake Sherwood and Triunfo Creek PMRs will be included the second version of the Santa Monica Bay Watershed non-regulatory products.



Santa Clara River Watershed Non-Regulatory Product Development

Description:

​​Santa Clara River Watershed non-regulatory products include the Flood Risk Database (FRD), Flood Risk Map (FRM), and Flood Risk Report (FRR).  Flooding sources included in the initial version of the Santa Clara River Watershed non-regulatory products include the Santa Clara River and tributaries.  Products include depth and analysis grids, risk assessment data using the average annualized loss (AAL), areas of mitigation interest (AOMI), and changes since last FIRM (CSLF).
