3.3.06: RESIDENTIAL ZONE LOT COVERAGE OF IMPROVEMENTS:
The maximum permitted lot coverage varies with lot size. Figure 3.3.06 of this section establishes the maximum permitted lot coverage for all uses in all residential zones.
To determine the lot coverage for a proposed development, calculate the following values and add to determine the total coverage. (Ord. 821, 2-23-2006, eff. 3-16-2006)

 Building/house footprint 100 percent of footprint area = A Decks, patios, walkways, plazas, etc. 50 percent of covered area = B Driveways, surface parking, etc. 35 percent of covered area = C Total = A+B+C
(Ord. 864, 2-12-2009)
Determine the maximum permitted lot coverage (A+B+C) for home sites by using figure 3.3.06 of this section. For example:

 Home sites equal to or less than 5,000 square feet 50 percent Home sites of 8,000 square feet 33 percent Home sites of 10,000 square feet 30 percent Home sites of 20,000 square feet 24 percent Home sites of 90,000 square feet 15 percent Home sites of 200,000 square feet and above 10 percent

Some examples:
(A)   Lot Size = 7,000 square feet.
House plus garage footprint = 1,800 square feet x 1.00 = 1,800 (A).
Patio = 200 square feet x 0.50 = 100 (B).
Driveway and walk = 300 square feet x 0.35 = 105 (C).
A + B + C = 1,800 + 100 + 105 = 2005.
Lot size = 7,000; from figure 3.3.06 of this section, maximum value for A + B + C = 36%, or 2,520.
So this example meets the coverage requirement.
(B)   Lot Size = 15,000 square feet.
House plus garage footprint = 3,500 square feet x 1.00 = 3,500 (A).
Patio and deck = 800 square feet x 0.50 = 400 (B).
Driveway and walk = 600 square feet x 0.35 = 210 (C).
A + B + C = 3,500 + 400 + 210 = 4,110.
Lot size = 15,000; from figure 3.3.06 of this section, maximum value for A + B + C = 26%, or 3,900.
So in this example, something will have to be reduced to bring the total to 3,900.
