Chapter 18.70
GENERAL PROVISIONS
Sections:
18.70.040 Development defined.
18.70.010 General provisions.
The provisions of the overlay district do not change the base zoning or range of uses permitted on a property. However, the overlay may restrict the placement of a use on a property to reflect natural constraints such as steep slopes, known geologic hazards, floodplains and creekbeds, and to protect the public health, safety and welfare. (Ord. 974 § 4 (Exh. A.2 § 4.1), 1998)
18.70.020 Applicability.
The geologic hazard overlay, flood hazard overlay and creek greenway overlay apply to specific properties as designated on the Rainier comprehensive plan and Rainier zoning map.
A. The geologic hazard overlay includes areas of known geologic hazard and areas with slopes over 20 percent.
B. The flood hazard overlay applies to the floodway and 100-year floodplain as mapped by the Federal Emergency Management Agency (FEMA).
C. The creek greenway overlay is applied to lands adjacent to Beaver Creek, Nice Creek, Fox Creek and Owl Creek. (Ord. 974 § 4 (Exh. A.2 § 4.2), 1998)
18.70.030 Development review.
Any proposed development on lands designated with the geologic hazard overlay or flood hazard overlay shall be considered through development review as required by Chapter 18.75 RMC. (Ord. 974 § 4 (Exh. A.2 § 4.2), 1998)
18.70.040 Development defined.

B. Any modification to an existing structure which substantially changes the structure (addition, expansion, structural modification);
C. Any proposed earthwork which will change the existing soil, drainage, slope, or load (cutting, filling, adding load), including leveling, whether for a subdivision or a parking lot;
D. Substantial changes in use; and/or
E. Other proposals deemed “development” by the reviewing staff. (Ord. 974 § 4 (Exh. A.2 § 4.1), 1998)
