The following tables, Table 1 and Table 2, set forth the basic parcel area, open space and bulk regulations which apply to all districts. These basic regulations are further defined and supplemented by additional requirements and exceptions in subsequent chapters. For convenience, the numbers of these chapters are set forth in column headings in the tables.

TABLE NO. 1
BASIC AREA, OPEN SPACE, BULK AND DENSITY REGULATIONS FOR
RESIDENTIAL DENSITY COMBINING DISTRICTS

* See Section 18.54.020 (B)
 a) To determine the maximum amount of floor area or impervious surface permitted on a parcel, the figures from Table 1 must be inserted in Tables 1A and 1B to determine the Adjusted Maximum Floor Area and Adjusted Maximum Impervious surface. The Adjusted Maximum Floor Area and Adjusted Maximum Impervious Surface figures then supersede the Maximum Floor Area and Maximum Impervious Surface figures from Table 1.
 b) For parcels over 7-1/2 acres and up to 10 acres, the floor area can be increased at the rate of 216 square feet per acre to a maximum of 10,121 square feet, and the impervious surface can be increased at the rate of 794 square feet per acre to a maximum of 21,807 square feet. For parcels 10 acres and larger, floor areas and impervious surfaces may exceed these limitations when a conditional use permit is granted therefor as provided in Chapter 18.72. The resultant floor area and impervious surface figures are to be inserted in Tables 1A and 1B to determine the Adjusted Maximum Floor Area and Adjusted Maximum Impervious Surface.

^a When the town engineer finds that a flood hazard map appears inaccurate, the engineer may modify said map for the purposes of the administration of Table 1A and Table 1B of the zoning ordinance and such modification shall be used in calculating the area utilized in line 4.

;sup\sup;In all combining districts, the 85% limitation shall also include any detached garage or carport required by Title 18 "Zoning" of this Code. See Sections 18.48.020 for exceptions to the 85% limitation.

BASIC AREA, OPEN SPACE, BULK AND DENSITY REGULATIONS
FOR SPECIAL AND COMMERCIAL DISTRICTS

(Ord. 2010-387 § 6, 2010; Ord. 1998-312 § 2, 1998; Ord. 1995-285 § 1 Exh. A (part), 1995; Ord. 1989-244 § 1 (Exh. A) (part), 1989; Ord. 1988-242 § 2 (Exh.

The architectural and site control commission may allow the eighty-five percent figure stipulated in Line 7 of Table 1A to be increased up to a maximum of one hundred percent when it can make all of the findings set forth below:

A.

Any one of the following:

1.

The larger building will result in a superior design for the property in terms of grading, tree removal and use of the property than would be possible without the requested increase.

2.

The larger building is appropriate because steep slopes, areas of unstable geology or areas subject to flooding so limit development of the property that in order to develop a reasonable plan for the property it is necessary to concentrate more than eighty-five percent of the floor area in a single building.

3.

The larger building is appropriate because the reduction in permitted floor area caused by steep slopes, unstable geology and/or areas subject to flooding so reduces the floor area permitted for any single building that in order to develop a reasonable plan for the property it is necessary to concentrate more than eighty-five percent of the floor area in a single building.

B.

The building will not impact significant views enjoyed by neighboring properties to any greater extent than would a design for the project without the increased floor area.

C.

The building will not in any substantial way negatively affect neighboring properties to any greater extent than would a design for the project without the increased floor area.

D.

The building will be in keeping with the character and quality of the neighborhood.

(Ord. 1998-312 § 3, 1998; Ord. 1995-285 § 1 Exh. A (part), 1995)

Any single-family residential building or related accessory building existing on October 25, 1995, may be increased one time up to a total of five percent of the existing floor area or one hundred fifty square feet, whichever is smaller, regardless of whether such increase exceeds the floor area limit that applies to the property. This provision shall not be applied to accessory dwelling unit maximums as described in subsections (i.) and (ii.) of Section 18.36.040.A.4.b.
