The project's Site Classification will dictate the specific stormwvtMt&
requirements applicable to your site. Completing this worksheet will help etermine the amount of
regulated impervious surfaceand whether your project falls into the classification of a Small Site
(Category I or Category 2), or a Minor Site. Please reference the Glossary (pp. 10-11), Figures D and
E, (pp. 8-9), and Examples (no. 11-12), to assist with completion of this worksheet.
1) Is Permeable Pavement' Proposed For Use on this Site? El Yes No
Refer to Stormwater Supplement Chapter 5.1 X
If YES, the subject area is to be considered impervious for initial site classification purposes. Include total
permeable pavement area in flae calculation of Non -Regulated, 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 Supplement Chapter 2 and Fig. C
Line 1: Identify the Non-Regulatfd Impervious Surface Area.
Line 2: Identify the Replaced Impervious Surface Area, dividing the total between Exempt and Regulated; 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 keplaced-Regulated 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 -.ot yet been applied.
Line 7: Identify the total area 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.
