18.76.080 Public infrastructure requirements.
The applicant for the PUD must provide all necessary public facilities to include, as a minimum, the following:
A. Dedication of Public Utilities. Public utilities being provided by the city must be dedicated to the city unless allowed to be private by the city.
B. Water, Sewer and Drainage Facilities. All water, sanitary sewer and drainage facilities must be constructed and installed in accordance with applicable city codes and standards, including design criteria, construction specifications, operational criteria, and approved engineering submittals.
C. Underground Facilities. All public utilities must be placed underground except those that by their nature must be on or above ground, such as streets, fire hydrants, power vaults, telephone pedestals and open watercourses. The applicant is responsible for making the necessary arrangements with the appropriate entities for the installation of such services.
D. Streets.
1. All streets must be constructed to the city’s standards. Variations from minimum standards for pavement and right-of-way widths or other dimensional or construction standards may be permitted when special design features of the PUD or topographic considerations warrant the variation. The applicant must submit a written justification for any proposed variation along with evidence that the minimal functional requirements of the proposed street improvements are being met. The city engineer shall review the proposed variation and shall determine if the minimal functional requirements are being met and shall make a recommendation to the city council whether the variation should be approved. The city council shall act upon the request and may require conditions of approval to ensure the minimal functional requirements are being met.
2. Private streets may be permitted within the PUD, provided they meet the following criteria:
a. Use of the private street is limited to those accessing property within the planning area or immediately adjacent to the planning area and is not needed by non-PUD residents to travel from one public street to another. The design of the private street shall be such that it will discourage any through traffic that is not related to the planning area itself.
b. The minimum pavement width for private streets shall be 28 feet; provided, that on-street parking is allowed only on one side of the street or 20 feet for alleys. The roadway section pavement depth for asphalt, crushed rock, and gravel base and the material specifications of these materials shall be the same as Auburn standards for public streets. Additional width may be required if determined to be needed to provide adequate circulation for the residents of the PUD. Factors to be considered include but are not limited to providing emergency equipment access, preventing conflicts between pedestrians and vehicle traffic, on-street parking, number of units, the need for sidewalks and bike paths. The pavement width and construction standards, to include but not limited to, illumination, signing, storm drainage, curbs, gutters, channelization, e.g., shall be determined by the city engineer at the time of preliminary plat or site plan approval. Private streets and/or access tracts and shared driveways that provide a second or additional access to lots/units shall be constructed to standards, as determined by the city engineer, considered to be appropriate for the situation. Factors to be considered include the number of units served, emergency access and traffic circulation.
c. All sites served by a private street greater than 600 feet in length shall have at least two access connections to a public street and provide for adequate emergency equipment access.
d. A legally incorporated property owners’ association assumes the responsibility and cost to repair and maintain the proposed private streets. If the association fails to maintain the street, the by-laws of the association give the city the right to maintain the street and charge the cost of the maintenance, including any administrative costs, to the association members.
e. The by-laws establishing the association must state that if future owners should request that private streets be changed to public streets, then the owners fully agree that, before acceptance of such streets by the city, the owners will bear full expense of reconstruction or any other action necessary to make the streets substantially consistent to the requirements of public streets, applicable at that time. (Ord. 6532 § 31, 2014; Ord. 5092 § 1, 1998.)
