1.0 SUBJECT TITLE: Farm Management Plans

2.1 The purpose of this administrative rule is to implement K.C.C. chapters 21A.24 (Critical Areas), 16.82 (Clearing and Grading), and 9.04 (Stormwater Management), by describing how landowners may obtain and use King Conservation District (KCD) approved Farm Management Plans to meet compliance as allowed by these codes. The intent is to protect critical areas by allowing agricultural landowners to undertake a specified set of activities using the proven standards, best management practices and planning systems developed by the Natural Resources Conservation Service (NRCS). The goal of the federally designed NRCS system is parallel to that of the Critical Areas Ordinance: to sustain the five resource systems on any property - soil, water, air, plant and animal - while also providing viability for agricultural operations. These practices are tailored to northwest Washington and applied by the local staff at the NRCS and KCD to meet the site characteristics and needs of the landowner. The NRCS practices include those that protect wetlands, wildlife and aquatic areas; those that enhance these resources; and those that manage drainage, groundwater and soils for sustainability, based on site slope, soils, precipitation and irrigation.

3.1 Rural landowners who are:

1. predominantly engaged in the practice of agriculture as determined through discussions between the landowner and staff of the King Conservation District or King County and including a site visit if needed, or

2. developing a property for multiple use that includes a Farm Management Component of a Rural Stewardship Plan (PUT- 8-20 PR)

3.2 Applicants for PBRS current use taxation farm and agricultural conservation land category.

5.1 Best Management Practice. A practice determined appropriate for existing or proposed farm site conditions and related agricultural activities, and that is consistent with the NRCS Field Office Technical Guide or with specific practices that have been mutually developed by the KCD and the County as documented in the Best Management Practices Supplement to this rule.

5.2 Dairy Nutrient Management Plan. A Farm Management Plan developed according to R.C.W. Chapter 90.64 guidance for dairy nutrient management.

5.3 DDES. Department of Development and Environmental Services. The County department, or its successor, that issues permits through which development activities are conditioned to meet county development regulations and standards.

5.4 Farm Management Plan. A long-term plan developed under the conservation planning process of the Natural Resources Conservation Service (NRCS) and including the standards in the Field Office Technical Guide as adapted for the Pacific Northwest Region and used by the King Conservation District. In order to be used for purposes of this rule, the plan shall contain the elements described in K.C.C. 21A.24.51.E (Section 138 E Ordinance 15051) and include an overall plan for the entire site including existing and anticipated agricultural uses and appropriate best management practices assembled from one or more of the following NRCS planning elements:

a. livestock management system;

b. horticultural management system;

c. site development plan (agricultural construction plan, for purposes of this rule);

d. agricultural drainage system;

e. fish and wildlife system; and

f. dairy nutrient management plan.

The plan may also include best management practices as agreed upon by the KCD, WLRD, and DDES such as those for installing field access roads, livestock bridges, manure lagoons, livestock flood sanctuaries, covered manure compost bins, and maintaining agricultural ditches with salmonids.

5.5 Field Office Technical Guide (FOTG). Guide developed and maintained by the United States Department of Agriculture Natural Resources Conservation Service, or its successor, and where applicable, the modified FOTG adapted to Northwest Washington pursuant to the Agriculture, Fish and Water statewide process.

5.6 Forested. A site that has been cleared under a class I, II, III, IV-S, or IV-G forest practice permit or that exceeds 10,000 square feet with a uniform density of tree cover totaling more than ninety trees per acre and with an average stem diameter at least 4 inches at breast height, not including areas that are actively managed as agricultural crops for pulpwood, Christmas trees or ornamental nursery stock.

5.7 KCD. The King Conservation District (KCD) is a state authorized special purpose district. For purposes of this rule, the King Conservation District refers not only to the managers and staff of the district, but also to the local employees of the federal Natural Resource Conservation Service whose expertise, standards and work are reflected in the work of the District.

a. building a residential structure within a grazed or tilled wed meadow.

b. building or expanding a non-residential agricultural structure within the buffer of a critical area or within a grazedor tilled wet meadow, wildlife habitat conservation area, critical aquifer recharge area, or coal mine, seismic, or flood hazard area;

c. construction of a farm field access road or livestock bridge that
