BEST MANAGEMENT PRACTICESBest Management Practices (BMP's) consist of sustainable approaches to land planning and management that protect soil and water resources against degradation. Resource management agencies, groups and educators identify and promote BMP's in varying ways. This appendix provides information on BMP's recommended by the Natural Resource Conservation Service (NRCS). The NRCS defines Best Management Practices in their Field Office Technical Guides according to the following criteria:
Conservation Practice -- A structural measure, a vegetative measure or a management activity used to protect, enhance or manage, soil, water, air, plant or animal resources
Conservation Practice Standard -- A set of statements that defines a practice; identifies the purposes and applicability of the practice; establishes criteria to support each purpose; lists special concerns useful in planning, designing, and constructing the practice; and establishes installation, operation and maintenance requirements.
Conservation Practice Specifications -- Site specific documents that establish the technical details and workmanship required to install the practices in accordance with the requirements of the practice standard.
The following is a partial list of current NRCS practices that apply to San Juan County. The definitions given are summaries taken from the Conservation Practice Standard pages for each practice in Field Office Technical Guide 4. In creating conservation plans, planners recommend that combinations of these practices be implemented in concert to achieve desired results and improve water quality.
