22.84.010 Density calculations.

A. Calculations for Determining Maximum Density, Where Expressed in Dwelling Units Per Acre. The entire site area may be used in the calculation of the maximum allowed residential density.

B. How to Calculate Density. Maximum density for an individual site shall be calculated by multiplying the site area (in acres) by the maximum dwelling units/acre in the applicable zone. When calculation results in a fraction, the fraction shall be rounded to the nearest whole number as follows:

1. Fractions of 0.50 and above are rounded up.

2. Fractions below 0.50 are rounded down. (Ord. 1190-21 § 2, 2021).

22.84.020 Lot coverage calculations.

Lot coverage refers to the area of a lot which is covered/occupied by a roofed building or buildings, usually expressed in square feet or percentage of land on the lot.

1. The area measured horizontally at the outside of external walls or supporting members of all primary and accessory structures.

2. The roof overhang shall not be included in the lot coverage unless it exceeds two feet, in which case only the outer two feet is excluded from the calculation of lot coverage.

3. Open beams and lattice work without a roof are not considered part of the lot coverage.

4. Minor appurtenances such as bay windows, chimneys and trim not extending more than two feet from the primary wall, and not extending the enclosed floor area, do not count in lot coverage.

5. Covered porches or decks that are not enclosed, are less than one hundred twenty square feet in footprint and are less than forty-two inches above grade do not count as lot coverage.

6. For lots which share an access easement (e.g., for a shared drive) the easement may be counted as lot area for the purpose of lot coverage calculation for the lot on which the easement is placed. (Ord. 1190-21 § 2, 2021).

22.84.030 Screening of exterior mechanical devices.

Air conditioners, heating, cooling, ventilating equipment, swimming pool pumps and heaters and all other mechanical devices shall be screened from surrounding properties and streets and shall be so operated that they do not disturb the peace. (Ord. 1190-21 § 2, 2021).

22.84.040 Screening of exterior mechanical devices.

Except on trash pickup days, all trash receptacles shall be screened from neighboring properties and public rights-of-way by an opaque visual barrier no lower than the maximum height of the receptacles. Provision of recycling bins shall be made. These shall be located near the trash receptacles and screened as required above. (Ord. 1190-21 § 2, 2021).

22.84.050 Yard projections and permitted intrusions into required yards.

Every required front, rear and side yard shall be open and unobstructed from the ground to the sky unless otherwise provided:

A. Fences and walls as specified and limited may project into the front, rear and side yards.

B. Cornices, sills, eave projections and awnings without enclosing walls or screening may project into a required yard by not more than thirty inches, provided the width of any required interior side yard is not reduced to less than two feet, six inches, and any yard abutting a street is not reduced to less than five feet.

C. Open, unenclosed, unroofed decks may project into any required rear or interior side yard; providing, however, that the decks are constructed at grade elevations, or in no event exceed thirty inches above adjoining grade.

D. Bay windows and garden windows which do not require a foundation may project into a required front, rear, or street side yard by not more than thirty inches; provided, that the width of any yard abutting a street is not reduced to less than five feet.

E. Stairs, balconies, covered or uncovered porches may project no more than one hundred twenty square feet into a required front or rear yard, provided lot coverage is not exceeded.

(Ord. 1190-21 § 2, 2021).
