Lake County Zoning Code Art. 7

• 7.11 Maximum permitted density: The number of lots which can be created from a parcel in this district shall be determined through Table 20. Unless modified by any “B” district, maximum permitted density is the sum of all values derived from Categories 1 through 4, but in no case shall the density exceed one (1) unit per twenty (20) acres. The maximum permitted density may be calculated based on the entire parcel or each proposed lot as long as all parcels conform to the density of Table 20. (Ord. 1749, 7/7/1988; Ord. No. 2402, 7/12/1997)

Table 20. Land Capacity/Capability

(Note: All numbers on the chart are in acres)

• (a) Category 1: The average cross slope of the parcel shall be determined by plotting the parcel on the appropriate U.S.G.S. quad sheet or other topographical map with a reliable scale prepared by a registered civil engineer or surveyor. The combined length of the contour lines, in scale feet, will be measured within the plotted area. The average cross slope is calculated utilizing the following formula:

S = .0023(I)(L)

A

where: S = Average cross slope in percent .0023 = Converts square feet to acres I = Contour interval in feet L = The combined length of the contour lines in linear feet A = The gross area in acres of the parcel

The result of the above formula will be rounded down to the nearest whole percentage point.

• (b) Category 2: The fuel loading for the parcel shall be determined using the Lake County General Plan Wildfire Hazard Map on file at the Lake County Planning

Department or any updated map indicating fuel load and/or fire hazard as approved by the Planning Commission. The maximum density shall be adjusted according to the parcel’s average cross slope and the corresponding line of Category 2 if the map indicates either a “high” or “extreme” rating for more than fifty (50) percent of the parcel. Alternative data establishing fuel load and wildfire hazard may be prepared by a registered forester.

• (c) Category 3: The landslide risk for the parcel shall be determined using the Lake County General Plan Landslide Risk Map on file at the Lake County Planning Department, or any updated map indicating geologic hazards and slope stability as approved by the Planning Commission. The maximum density shall be adjusted according to the parcel’s average cross slope and corresponding line of Category 3 if the map indicates either an “unstable” or “existing unconsolidated to moderately consolidated landslide debris” rating for more than fifty (50) percent of the parcel. Alternative data establishing land stability may be prepared by a registered geologist with professional training in structural geology, or a certified engineering geologist.

• (d) Category 4: The distance shall be measured in air miles between the edge of the parcel and the location, on the effective date of this Ordinance, of the fire station of the nearest community designated in the 1981 Lake County General Plan’s Rural Lands policy and from the Hidden Valley substation of the South Lake Fire Protection District. The maximum density shall be adjusted according to Category 4 if the parcel is over five (5) air miles from a designated community. (Ord. 1749, 7/7/1988; Ord. No. 2402, 7/12/1997)

• (e) The maximum permitted density shall be determined by adding any assigned values in Categories 1, 2, 3, or 4. To determine the number of lots which can be created, divide the parcel’s gross acreage by the calculated maximum permitted density. The maximum permitted density may be calculated based on the entire parcel or each proposed lot as long as all parcels meet the minimum required density. (Ord. No. 2402, 7/12/1997)

• (f) Alternative data sources may be substituted for data sources identified in Categories 1 through 4 above, subject to approval by the Planning Commission. (Ord. No. 2402, 7/12/1997)

• (g) The Review Authority may increase the maximum permitted density permitted by Table 20 by up to fifty (50) percent when the Review Authority finds all of the following: (Ord. 1749, 7/7/1988)

  1. Surrounding parcel sizes are substantially similar in size to those proposed.

  2. All parcels to be created front on or will front on a publicly-maintained road, or all parcels front on or will front on a privately-maintained road where maintenance is insured by a homeowner’s association(s) declaration of conditions, covenants and restrictions (CC&R’s) or legal, binding road maintenance agreements across the subdivision site and to a countymaintained road.

7-5

3. All proposed parcels front on maintained roads without utilizing flag lot design.

4. The proposed density is not more than one (1) unit per twenty (20) acres.

5. The site is not adjacent to any “TPZ”, “APZ”, “A” or “AI” zoning district.

6. The site does not contain any area identified in the Lake County General Plan as “Wetlands Protected”, Figure V-13; or “Natural Areas”, Figure V-5; or “Critical Resource and Conservation Areas”, Figure V-6.

7. The proposed density increase will not conflict with any specific policy or objective of the Lake County General Plan.

8. Any subdivision approval pursuant to this Subsection has been conditioned so that a building envelope(s) is located on each parcel meeting the following criteria:

   • i. Is one (1) acre in size or larger.

   • ii. Will accommodate a typical dwelling, access road, and leach field with one hundred (100) percent expansion area.

   • iii. Has a cross slope of less than fifteen (15) percent.

   • iv. Can be served by an access road or driveway of less than fifteen (15) percent grade.

   • v. Is rated as low or moderate fire hazard.

   • vi. Construction within the building envelope and along the access route will not adversely affect geological stability. (Ord. 1749, 7/7/1988)
