An access permit must be applied for and issued prior to beginning any work within the county right of way. Access must be completed prior to issuance of any building permits. 6.2 The Subject property has a federally owned bridge (United States Bureau of Reclamation) and requires a replacement of the bridge and transfer of ownership to privately owned and maintained bridge. 6.3 Kittitas Reclamation District requires a crossing license to be obtained to cross the KRD owned canal prior to construction. 6.4 Bonneville Power Administration (BPA) requires that any activity in parcels 20-14- 29000-0019, 20-14-290000-0017, 20-14-32000-0001, 20-14-32000-0003, & 20-14- 32000-0004 that occurs in the right of way needs to be permitted by BPA prior to installation or construction and acquire a Land Use Agreement for any portion of the development plans that lie within the BPA's right of way. 7. Water 7.1 Activities such as road widening, stump pulling and clearing, grading and fill work and utility placements may require a NPDES Construction Stormwater Permit issued by the Department of Ecology prior to start of construction. This permit requires the preparation of a Stormwater Pollution Prevention Plan (Erosion Sediment Control Plan). It is the applicant's responsibility to contact the Department of Ecology. 7.2 On-site stormwater management that conforms to the specifications of the most current version of the Stormwater management Manual for Eastern Washington is required of this development. Stormwater systems shall be designed to store stormwater generated by a 24-hour, 25 -year storm event. Stormwater system designs shall be prepared and stamped by a civil engineer licensed in the State of Washington. The stormwater system design shall be presented to Public Works and reviewed by the County Engineer prior to issuance of a building permit. The stormwater system construction shall be certified by a licensed engineer prior to issuance of an occupancy permit. 7.3 All water proposed to be used must be obtained from a water budget neutral source meeting conditions of Kittitas County Code Chapter 13.35. 7.4 Withdrawals of groundwater on the subject property are subject to the rules and regulations adopted and administrated by the Washington State Department of Ecology; this includes the use of water for irrigation. Legally obtained water must be used on-site. 7.5 Chapter 173-150 WAC provides for the protection of existing rights against impairment, i.e. interruption or interference in the availability of water. If water supply in an area becomes limited, use could be curtailed by those with senior water rights. Department of RZ-15-00001 Big Creek Trails Page I 1 of 13
