(1) Intent. The intent of the public use district is to protect public facilities such as parks, schools, and wastewater treatment facilities from pressure of alternative development. Public use zoning is applied to those areas deemed necessary for the long-term use and enjoyment of the town and its citizens; and to provide for and protect public institutional facilities within the town, including public utility installations.

(2) Uses Allowed. Uses allowed in the PU district are shown in the district use chart in Appendix A of this title.

(3) Special Provisions in the Public Use Zone. The Methow Valley School District property, formerly the Twisp High School, shall be allowed to include uses compatible with C-1 commercial zone through the issuance of an administrative permit.

(4) Dimensional Requirements. Lot sizes, allowable densities, lot coverage, height and setbacks in the PU district shall be as set forth in Table 7 – Public Use and Airport Development Districts.

(5) All uses shall comply with all applicable basic provisions in Chapter 18.15 TMC, including requirements related to performance standards. (Ord. 632 § 1, 2011; Ord. 620 § 7(1), 2010)

18.35.020 Airport development district.

(1) Intent. The airport development (AIR) district, pursuant to RCW Title 14, is a specialized public use area designed to allow for the location and development of a wide range of uses that are compatible with the primary use of the site as an airport. The district is intended to provide uses that complement the airport, in a location that insulates the major residential areas from the noise, traffic, and aesthetic impacts of such uses. Allowed uses within the AIR district are intended to be limited to those uses shown in the district use chart in Appendix A of this title that can be operated without threatening the integrity of the airport’s operation. Uses that can be conditioned to meet those goals but that, uncontrolled, could threaten the utility of the airport, should be allowed only after thorough review of the intended project and imposition of protective conditions and limitations thereon. Development within the AIR district should be consistent with Okanogan County’s airport development district provisions.

(2) Uses Allowed. Uses allowed in the AIR district are shown in the district use chart in Appendix A of this title.

(3) Dimensional Requirements. Lot sizes, allowable densities, lot coverage, height and setbacks in the AIR district shall be as set forth in Table 7.

(4) All uses shall comply with all applicable basic provisions in Chapter 18.15 TMC, including requirements related to performance standards.

(5) Special Regulations.

(a) All service, processing or storage on property within 50 feet of a residential district shall be wholly within an enclosed building or screened from view from the residential district by an approved Type V buffer, as described in TMC 18.20.160(9)(e).

(b) Access from a public street to properties in an airport development district shall be so located as to minimize traffic congestion and avoid directing airport district traffic onto residential streets.

(c) Building entrances or other openings adjacent to a residential or commercial district shall be designed to minimize the cause of glare, excessive noise, or otherwise adversely affect the use or value of the adjacent property.

(d) The storage, treatment, processing and manufacture of hazardous materials and/or waste shall only be allowed if such activities are appurtenant to an existing or proposed permitted use. The development of a use specifically for these purposes shall be prohibited. (Ord. 620 § 7(2), 2010)
