18.30.170 Setbacks – From regional utility corridors.
(1) In subdivisions and short subdivisions, areas used as regional utility corridors shall be contained in separate tracts.
(2) In other types of land development permits, easements shall be used to delineate regional utility corridors.
(3) All structures shall maintain a minimum distance of five feet from property or easement lines delineating the boundary of regional utility corridors, except for utility structures necessary to the operation of the utility corridor or when structures are allowed by mutual agreement in the utility corridor.
(4) Any structure designed for human occupancy, except for utility structures not normally occupied that are necessary for the operation of the pipeline or a minor communication facility, shall maintain a minimum distance of 100 feet from a hazardous liquid or gas transmission pipeline located within a regional utility corridor. The setback distance may be modified if the applicant demonstrates the following:
(a) A 100-foot setback would deny all reasonable use of the property; or
(b) That the structure would be protected from radiant heat of an explosion by berming or other physical barriers; or
(c) That a 100-foot setback would be impractical or unnecessary due to existing geographical features, streets, lot lines, or easements; or
(d) That no other practical alternative exists to meet the demand for service; and
(e) That the applicant will construct a hazardous liquid or gas transmission containment system or other mitigating actions if the City finds that leakage could accumulate within 100 feet of the pipeline. Any containment system or other mitigating actions required by this section shall meet all applicable Federal, State and local regulations. (Ord. 42-02 § 2 (21A.12.140))
