The following development and redevelopment projects, termed “planning priority projects,” shall comply with the requirements of § 16.36.050:
(A) All development projects equal to 1 acre or greater of disturbed area that adds more than 10,000 square feet of impervious surface area.
(B) Industrial parks 10,000 square feet or more of surface area.
(C) Commercial malls 10,000 square feet or more of surface area.
(D) Retail gasoline outlets with 5,000 square feet or more of surface area.
(E) Restaurants (Standard Industrial Classification (SIC) of 5812) with 5,000 square feet or more of surface area.
(F) Parking lots with 5,000 square feet or more of impervious surface area, or with 25 or more parking spaces.
(G) Streets and roads construction of 10,000 square feet or more of impervious surface area.
(H) Automotive service facilities (Standard Industrial Classification (SIC) of 5013, 5014, 5511, 5541, 7532-7534 and 7536-7539) 5,000 square feet or more of surface area.
(I) Projects located in or directly adjacent to, or discharging directly to an environmentally sensitive area (ESA), where the development will:
(1) Discharge stormwater runoff that is likely to impact a sensitive biological species or habitat; and
(2) Create 2,500 square feet or more of impervious surface area.
(J) Single-family hillside homes.
(K) Redevelopment projects.
(1) Land disturbing activity that results in the creation or addition or replacement of 5,000 square feet or more of impervious surface area on an already developed site on planning priority project categories.
(2) Where redevelopment results in an alteration to more than fifty percent of impervious surfaces of a previously existing development, and the existing development was not subject to post-construction stormwater quality control requirements, the entire project must be mitigated.
(3) Where redevelopment results in an alteration of less than fifty percent of impervious surfaces of a previously existing development, and the existing development was not subject to post-construction stormwater quality control requirements, only the alteration must be mitigated, and not the entire development.
(4) Redevelopment does not include routine maintenance activities that are conducted to maintain original line and grade, hydraulic capacity, original purpose of facility or emergency redevelopment activity required to protect public health and safety. Impervious surface replacement, such as the reconstruction of parking lots and roadways which does not disturb additional area and maintains the original grade and alignment, is considered a routine maintenance activity. Redevelopment does not include the repaving of existing roads to maintain original line and grade.
(5) Existing single-family dwelling and accessory structures are exempt from the Redevelopment requirements unless such projects create, add, or replace 10,000 square feet of impervious surface area.
(L) Any other project as deemed appropriate by the Director.
