The project's Site Classification will dictate the specific stormwater management - —.11
requirements applicable to your site. Completing this worksheet will help determine the amount of
regulated impervious surface and whetheryour project falls into the classification of a Small Site
(Category I or Category 2), or a Mnor Site. Please refe mce ie GlossM 10-1 ures D and
. 8-9). and Ex (pp. L—ILF—ig
E. (pp a=les (10D. 11-12). to as;ist with co ipletion of this worksheet.
1) is Permeable Pavement' I't-o—posed For Use on this Site?
— Refer to Stormwater Supplement Chapter 5.1 El Yes No
If YES, the subject area is to be considered impervious for initial site classification purposes. Include total
permeable pavement area in the calculation of Non- ' mulated, Replaced and/or New impervious surface
areas in the table below.
2) Determine the Amount and Type of Existing & Proposed Impervious —Surface for the Site
Refer to Stormwater Su lement Chapter 2 and Fig. C
Line 1: Identify the Non -Regulated Impervious Surface Area.
Line 2: Identify the Replaced Impervious Surface Area, dividing the total between Exempt and Eggglated; either or both
may be zero. Note: For project classification purposes, Replaced Impervious may only be considered exempt
under certain conditions. Refer to the Glossary and Figure D.
Line 3: Identify the New Impervious Surface Area for your project. All impervious areas created post -July 7, 1977 or
after the date of annexation into the City are regulated & should be included in this total unless they can be
categorized separately as a Replaced -Regulated area.
Line 4: Enter the sum of the total plus the total New impervious areas.
Line 5: Identify the total area currently mitigated by an existing city -approved stormwater management system.
Line 6: Enter the sum of the value in Line 4 less the value in Line 5 to identify the total Regulated area in which
stormwater controls have not yet been applied.
Line 7: Identify the total a rea proposed to be mitigated through the use of Low Impact Development Techniques.
Line 8: Identify the total area proposed to be* mitigated through conventional Stormwater Management Techniques.
