DOMINGUEZ WATERSHED MANAGEMENT PLAN
WATERSHED MANAGEMENT
WATER RESOURCES QUESTIONNAIRE
Purpose of Questionnaire:
The Dominguez Watershed Management Plan is being prepared to help guide management decisions to protect, enhance, and restore beneficial uses (water quality, biological resources, recreation) of the watershed in balance with economic impacts. In order to prepare the
Dominguez Watershed Management Plan in a manner that will be useful to the variety of stakeholders in the watershed, it is necessary to have an understanding of existing watershed management procedures, watershed problems, unmet needs, enhancement and restoration opportunities, and stakeholder goals. The purpose of this questionnaire is to gather this type of relevant information, which is not easily available from reports or maps.
How the Questionnaire will be Used:
Provided information will be used to identify sources of information that will contribute to accurate description of existing watershed conditions, understanding of watershed issues, focus planning efforts on relevant issues, and to formulate recommendations for watershed management actions.
Your Time is Valuable:
Thank you for your time in filling out the questionnaire.
How to Fill Out the Questionnaire:
Most questions are multiple choice or require a “yes” or “no” answer. However, most “yes” answers will require additional information in the form of a brief explanation. If more room is needed for the explanation than the space provided, extra blank pages are provided at the end of the questionnaire for that purpose. Some information may require personal follow-up for details too complicated to be provided in a brief response. In that case, please provide contact information (name, telephone number, e-mail address).
The attached map should be used to show locations of specific problems. An extra copy of the map is provided if you would like to make copies of the map to identify more than one type of problem.
Contact Us:
The questionnaire should not be considered all encompassing. We welcome any additional input you may consider relevant to the development of a responsive watershed management plan. The extra blank pages can be used for that purpose or please contact the following individuals to further discuss watershed issues. Please return completed questionnaires to David Rydman.
