Welcome to RMA

The Resource Management Agency strives to ensure that its customer service standards are consistent with the Agency’s Mission Statement:

The mission of the Resource Management Agency, in cooperation with the public and our partner agencies, is to protect the consumer and community’s health, safety, and environment by carrying out adopted laws and policies, and educating, assisting, and empowering Ventura County residents and businesses to be good stewards of the land and our resources.


In addition, RMA has identified those core values which will guide us in carrying out our mission. These values are directly related to our customer service and include:

  • Honesty, hard work, and ethical behavior

  • Transparency and accountability

  • Equitable treatment and respect of all constituents

  • Excellence in service delivery

The purpose of the Pre-Submittal Analysis is to provide you with information regarding County policies, regulations and constraints that may have a major effect upon a contemplated project. A Pre-Submittal Analysis is recommended when the Ventura County Ordinance Code Zoning Matrix cannot readily categorize a proposed project or when the contemplated project is “extraordinary” in its scope, type or potential impacts on the environment. A Pre-Submittal Analysis is required prior to filing an application for a Tract Map and recommended for Parcel Map applications.

  • Preliminary Legal Lot Determination

For a more formal determination of legal lot status, an application must be submitted to the Public Works Agency, County Surveyor Division, for a Certificate of Compliance (“legal lot certificate”).

For application forms and further information, please contact:
County Surveyor’s Office (805) 654-2067
