Concurrency | Public Works and Buildings

5. A concurrency test, and any resulting certificate of concurrency, shall be administrative actions of the City that are categorically exempt from the State Environmental Policy Act.

level of service standards for intersections, corridors and segments shall be achieved and maintained, no later than six years from the date of the development. 5. In the event that the applicant is required to construct a public facility, the development cannot be occupied until the public facility is completed, or the applicant provides the City with a performance bond that is acceptable to the City. 6. The City shall determine which additional public facilities are needed to be included in the Capital Facilities Plan Element of the Comprehensive Plan to achieve the adopted level of service standards. Such additional public facilities shall be underwritten by a financial commitment.

E. Level of service standards

1. In conducting the concurrency test in accord with this chapter, the intersection LOS standards adopted in the Transportation Element of the Comprehensive Plan are LOS D for intersections that include principal arterials and LOS C for intersections that include minor arterials or collector arterials. The LOS for intersections with principal arterials may be reduced to E for intersections that require more than three approach lanes in any direction. The intersection standards shall be applied to both the morning and afternoon peak hours. The LOS standard for the higher road classification shall be the standard applied.

F. Certificate of concurrency

1. A certificate of concurrency shall be issued by the public works director or his/her designee after the concurrency test is passed. 2. Upon issuance of a certificate of concurrency, the City shall reserve capacity on behalf of the applicant, and indicate the reservation on the certificate of concurrency. 3. A certificate of concurrency shall expire if the development permit for which the concurrency is reserved is not applied for within 180 days of issuance of the certificate of concurrency. 4. A certificate of concurrency shall be valid for the development permit application period and subsequently for the same period of time as the development permit for which it was issued.

2. Repealed by Ord. O2020-524.

3. In conducting the concurrency test in accord with this chapter, the City shall apply the level of service standards for the concurrency intersections as designated in subsection 1. of this section. If any intersection operates at or better than the level of service standards, the concurrency certificate shall be granted. If any concurrency intersection operates worse than the level of service standards, the concurrency certificate will be denied, or the applicant may select one of the options described in SDC 21.08.020D.3. 4. In conducting the concurrency test, the City shall find that the impact of development occurs, and therefore the
