STATE OF WASHINGTON County of Jefferson IN THE MATTER OF DELAYING } IMPLEMENTATION OF AMENDMENTS TO } UDC SECTION 6.7, SAID AMENDMENTS } HAVING BEEN PREVIOUSLY ENACTED } AS PART OF ORDINANCE #21-1220-02 } ORDINANCE NO. 02-0210-03 WHEREAS, the Board of Jefferson County Commissioners ("the Board") has, as required by the Growth Management Act, state law codified at RCW 36.70A.010 et seq., set in motion and completed the process for proper professional review and public notice and comment with respect to any and all proposed amendments to the County's Comprehensive Plan (the "Plan"), a Plan that was originally adopted by Resolution No. 72-98 on August 28, 1998 and subsequently amended, and; WHEREAS, one of the adopted amendments to the County's Comprehensive Plan (MLA #02-241) changed the boundary for the rural commercial district known formally as the Glen Cove LAMIRD; and WHEREAS, the change in the Glen Cove LAMIRD boundary also required changes, revisions and additions to certain portions of this County's GMA-driven development regulations, which are known as the Unified Development Code or "UDC;" and WHEREAS, the changes to the UDC necessitated by the changes to the boundary of the Glen Cove LAMIRD were submitted as MLA #02-329, i.e., a separate amendment document for consideration by staff, outside agencies and the public; and WHEREAS, MLA #02-329 contained a copy of the proposed "line-in, line-out" changes, revisions; that would be made to the UDC if MLA #02-329 were approved by the Board; and 02-0210-03 Ordinance No. _ Delaying Implementation of Amendments to UDC Section 6.7 WHEREAS, those proposed "line-in, line-out" changes, revisions and additions included changes to UDC §6.7, entitled "Stormwater Management Standards," specifically changes that would make the most current Washington State Department of Ecology [or "DOE"] Stormwater Management Manual, also known as the "2001 Manual," the controlling document for any future application [at any location in the unincorporated County] for a County-issued stormwater management permit; and WHEREAS, adoption by the County of the more stringent standards described and laid out within the "2001 Manual" was expressly included at page 2-62 [last bullet on the page] of the Draft SEIS issued in late August 2002; and WHEREAS, a decision to expressly state in the UDC that the County will impose upon any applicant for a County-issued stormwater management permit the standards described and listed in the 2001 Manual conforms with the adopted Comprehensive Plan or "CP" Land Use Policy (or "LNP") 26.1 because that LNP [added to the CP in November 1999 as part of a Hearings Board Compliance Order] states the County will require new development "to comply with the latest edition of the DOE's Stormwater Manual for the Puget Sound Basin;" and WHEREAS, Ordinance #14-1213-02, which enacted and approved Mineral Resource Overlay designations for Fred Hill Materials, Inc. and W. E. Seton, expressly refers to the concept that the County will use the "2001 Manual" when it evaluates any requests for mining or excavating permits on the parcels that have been newly designated as Mineral Resource Lands; and WHEREAS, Condition #3 imposed on Fred Hill Materials within Ordinance #14- 1213-02 expressly states that the operations there shall be subject to the standards found in the "latest edition of the [DOE] Stormwater Management Manual for Western Washington;" and WHEREAS, the above statements prove the clear intent of this Board, as the elected legislature of this County, to adopt and utilize the most current version of the DOE Stormwater Managemel}t Manual for Western Washington; and Page 2 --~- Ordinance No. 02-02f9eI~Ýing Implementation of Amendments to UDC Section 6.7 WHEREAS, the omission from Exhibit "C" to Ordinance #18-1213-02 of any language that adopts and enacts the "2001 Manual" as the official Manual that controls the application process for any stormwater management permit that relates to real property located within the unincorporated portions of Jefferson County was clearly a clerical error rather than an intentional policy decision of the Board; and WHEREAS, the County has stated since at least May 1, 2002 its intent to make adoption of the "200 I Manual" a part of what it accomplishes during this CP amendment cycle; however WHEREAS, the transition to reliance upon the "2001 Manual" is, in reality, fraught with more consequences and obstacles than originally thought; and WHEREAS, the "2001 Manual" has lower thresholds that establish the bright-line between a "de minimus" activity [an activity not requiring the applicant to utilize and comply with the "200 I Manual"] and those which will require oversight through the "2001 Manual," which inevitably leads to the conclusion that more activities will be regulated pursuant to the "2001 Manual" than would be regulated under the earlier version of the relevant Stormwater Management Manual; and WHEREAS, County staff, specifically the planners from Community Development and personnel from Public Works, have determined that it simply is not possible to quickly transition (literally overnight) from understanding, explaining and utilizing the earlier Stormwater Management Manual one day to understanding, explaining and utilizing the "2001 Manual" the next day; and WHEREAS, County staff is not sufficiently familiar with the procedural and substantive components of the "200 I Manual" to adequately explain the rules that would be controlling if the "2001 Manual" were applied to a specific application; and WHEREAS, the County staff will need training and experience with hypothetical applications and/or enforcement situations in order to become acquainted with the new rules detailed in the "2001 Manual," and WHEREAS, having County staff attempt to utilize, explain and understand the "2001 Manual" in real-world situations that are of importance to any particular applicant Page 3 02-0210-03 Ordinance No. _ Delaying Implementation of Amendments to UDC Section 6.7 when they do not feel comfortable with the provisions of the "2001 Manual" would only invite error, repetition of tasks and citizen discontent; and WHEREAS, County staff has previously sought estimates relating to the cost of obtaining the training they would need to "get up to speed" on the "2001 Manual;" and WHEREAS, the County would rather, when it comes to using, understanding and explaining the "2001 Manual," do it right than do it quickly; and WHEREAS, an immediate implementation date for the "2001 Manual" was a wiser step in theory than it was in fact; WHEREAS, County staff has stated that they will need several months to "get up to speed" on the procedural and substantive sections of the "2001 Manual," and WHEREAS, the County Commission is no less committed to adoption and use of the "2001 Manual" than it was when it approved Ordinance #21-1220-02 in December 2002; and WHEREAS, this Ordinance has been the subject of a public hearing before the elected County Commissioners. NOW, THEREFORE, BE IT ORDAINED by the Jefferson County Board of County Commissioners as follows: Section One: The attached document entitled Exhibit "A" shall be the adopted and effective language ofUDC Section 6.7 from the date of adoption of this Ordinance until the close of business on June 30,2003.

Common impervious surfaces include roofs, driveways, patios, packed earth. and oiled surfaces. Open, uncovered retention! detention facilities shall not be considered as impervious surfaces. e. A "land-disturbing activity" results in a change in the existing soil cover (both vegetative and nonvegetative) or the existing topography, and include but are not limited to demolition, construction, clearing, grading, filling, and excavation. 2. Exemptions. Commercial agriculture, and forest practices regulated under WAC 222, 'except for Class IV General forest practices and COHPs (see Section 4.16 of this Code), are exempt from the provisions of the minimum requirements. 3.

Open, uncovered retention/detention facilities shall be considered impervious surfaces for purposes of runoff modeling. d. "Land-disturbing activity" is any activity that results in movement of earth, or a change in the existing soil cover (both vegetative and non-vegetative) and/or the existing soil topography. Land disturbing activities include, but are not limited to clearing, grading, filling, and excavation.
