21A.40.010 Purpose. Repealed Ord. O2021-540 SeeTitle 21: Sammamish Development Code

The purpose of this chapter is to provide adequate parking for all uses allowed in this title, to reduce demand for parking by encouraging alternative means of transportation including public transit, rideshare and bicycles, and to increase pedestrian mobility in urban areas by:

(1) Setting minimum off-street parking standards for different land uses that assure safe, convenient and adequately sized parking facilities within activity centers;

(2) Providing incentives to rideshare through preferred parking arrangements;

(3) Providing for parking and storage of bicycles;

(4) Providing safe direct pedestrian access from public rights-of-way to structures and between developments; and

(5) Requiring uses that attract large numbers of employees or customers to provide transit stops. (Ord. O99-29 § 1)

21A.40.020 Authority and application. Repealed Ord. O2021-540 SeeTitle 21: Sammamish Development Code

(1) Before an occupancy permit may be granted for any new or enlarged building or for a change of use in any existing building, the use shall be required to meet the provisions of this chapter.

(2) If this chapter does not specify a parking requirement for a land use, the director shall establish the minimum requirement based on a study of anticipated parking demand. Transportation demand management actions taken at the site shall be considered in determining anticipated demand. If the site is located in an activity center or community business center, the minimum requirement shall be set at a level less than the anticipated demand, but at no less than 75 percent of the anticipated demand. In the study the applicant shall provide sufficient information to demonstrate that the parking demand for a specific land use will be satisfied. Parking studies shall be prepared by a professional engineer with expertise in traffic and parking analyses, or an equally qualified individual as authorized by the director.

(3) If the required amount of off-street parking has been proposed to be provided off-site, the applicant shall provide written contracts with affected landowners showing that required off-street parking shall be provided in a manner consistent with the provisions of this chapter. The contracts shall be reviewed by the director for compliance with this chapter, and if approved, the contracts shall be recorded with the King County records and elections division as a deed restriction on the title to all applicable properties. These deed restrictions may not be revoked or modified without authorization by the director. (Ord. O99-29 § 1)
