Initial Applicability Checklist
Applicant Name: Esdras & Julia Ruelas
I989
Project Name: Ruelas Guest Unit
Does the proposed project incorporate any of the following categories? Yes No
(All questions must be answered)
I New Developments -This category applies to commercial, industrial, residential, mixed-use, and public projects
that meet or exceed 10,000 square feet of impervious surface collectively over the entire project. X
Modifications to Existing Developments—This category applies to projects that create, add, extend, or replace
5,000 square feet or more of impervious surface on an already developed site. Note: If modifications create less
2 than 50% of the impervious surface of a previously existing development, and the existing development was not X
originally subject to WQMP/SSMP requirements,a WQMP/SSMP shall be required only for the addition, and not
to the entire development.
3 One Acre Threshold Projects—This category applies to projects that result in the disturbance of one acre or more X
of land,regardless of impervious surface coverage.
Automotive Shops —This category applies to projects that service motor vehicles (including but not limited to
4 wholesale/retail supplies, tires and tubes, body and upholstery repair, painting, exhaust system repair, tire X I
retreading,glass replacement,transmission repair,general maintenance,general repairs). b
Restaurants-This category applies to establishments that prepare and sell foods and drinks and will exceed 5,0W
square feet of land development. Restaurants where land development is 5,000 square feet or less must meet all
5 SSMP/WQMP requirements except for conventional structural treatment BMPs,hydromodification,and sizing X
requirements for LID BMPs.
I
Hillside Developments—This category applies to projects that create 5,000 square feet of impervious surface,and
6 are located in an area with known erosive soil conditions,and will include grading on a natural slope that is 25%or X
steeper.
Environmentally Sensitive Areas(ESAs)—This category applies to projects located within or directly adjacent
to or discharge directly to an ESA,or to receiving waters within an ESA,and are expected to meet or exceed 2,500
square feet of impervious surface, or increase the area of imperviousness to 10% or more of their naturally
7 occurring condition. Note: "Directly adjacent" means within 200 feet of the ESA. "Discharging directly to" X
means outflow from a drainage conveyance system that is composed entirely of flows from the project, and not
commingled with flows from adjacent lands.
Parking Lots—This category applies to projects that meet or exceed S,ODO square feet of impervious surface for
8 temporary parking or storage of motor vehicles. This category includes parking areas associated with any of the X
categories listed above.
9 New Streets, Roads, Highways and Freeways —This category applies to projects that meet or exceed 5,000
square feet of impervious surface for the transportation of automobiles,trucks,motorcycles,and other vehicles. X
10 Retail Gasoline Outlets — This category applies to projects that meet or exceed 5,000 square feet of land X
development,or if an 'Average Daily Traffic' (ADT)count of 100 or more vehicles per day is projected.
If you answered"YES"to any of these questions,a WQMP/SSMP must be prepared and submitted.
TMC 8.28.500(C)(3): A WQMP/SSMP shall be required if the city engineer determines that the development may
result in the discharge of significant levels of a pollutant into any tributary to any storm drain system.
TMC 8.28.500 (C)(2): Projects not requiring a WQMP/SSMP will be required to implement equivalent BMPs
designated by the city according to conditions and requirements established by the city engineer.
