§ 22.344

The Twin Lakes Community Standards District ("CSD") is established to preserve the character of the Twin Lakes community and to encourage the provision of essential improvements appropriate for its unique rural character, as defined in the Community Plan. This CSD is one means of implementing the goals and objectives of the Twin Lakes Community Plan. The Twin Lakes Community Plan was developed primarily to address severe problems involving sewage disposal and circulation in a small-lot subdivision.

22.344.060 - Community Wide Development Standards.

A.

Parking and Driveway Requirements.

1.

On-street parking shall observe posted signage.

2.

A minimum driveway length of 20 feet, as measured from a line parallel to and a minimum of 10 feet from the centerline of the driven roadway, is required in order to ensure adequate off-street parking. If two standard size vehicle parking spaces are provided on site and not within the required yard setbacks, this provision may be waived.

B.

On-site and Off-site Improvements. All new homes or improvements to existing homes which exceed 25 percent of the current market value of the existing home must satisfy the following:

1.

All roads or access easements on site, as well as segments of all roads abutting the parcel must be improved with a minimum of 20 foot width of paving, to be approved by Public Works.

2.

Fire hydrants must be accessible to the site, and comply with current standards of the Fire Department.

3.

Sewage disposal facilities must be sized to serve the requested use, based on current Department of Public Health's standards.

4.

The construction of improvements needed to comply with Subsection B.1 through B.3, above, shall be the full responsibility of the project applicant.

5.

The County shall impose as a condition of its approval of any affected development a requirement for construction of the necessary improvements.

(Ord. 2019-0004 § 1, 2019.)

22.344.070 - Zone Specific Development Standards.

(Reserved)

22.344.080 - Area Specific Development Standards.

A.

Area 1 (Small Lot Subdivisions)—All Property Located Within the Following Records of Survey: 24-25, 2544, 25-46, 26-42, 28-23.

1.

Slope Intensity Formula. Construction of residential units or any improvements to residential units on a lot of less than 6,000 square feet shall be subject to the following:

a.

The maximum allowable gross structural area of a residential unit to be constructed on a building site shall be determined by the following formula:

GSA = (A/5) × [(50-S/35] + 800

Where: GSA = The allowable gross structural area of the permitted development in square feet. The GSA includes the total floor area of all enclosed residential and storage areas but does not include vent shafts, garages or carports designed for the storage of autos.

A = The area of the building site in square feet. The building site is defined by the applicant and may consist of all or a designated portion of the one or more lots comprising the project location. All permitted structures must be located within the designated building site; and

S = The average slope of the building site in percent as calculated by the formula: S = I × L/A × 100;

Where: S = Average natural slope in percent;

I = Contour interval in feet, at not greater than 25-foot intervals, resulting in at least five contour lines;

L = Total accumulated length in feet of all contour intervals (I); and

A = The area of the building site in square feet.

b.

All slope calculations shall be based on natural, ungraded conditions. Maps of a scale generally not less than one inch equals 10 feet (1" = 10'), showing the building site and natural slopes, prepared by a licensed surveyor or registered professional civil engineer, shall be submitted with the application. If slope is greater than 50 percent, enter 50 for S in the GSA formula.

c.

The maximum allowable GSA as calculated above may be increased as follows:

i.

Add 500 square feet or 12.5 percent of the total lot area, whichever is less, for each lot which is contiguous to the designated building site, provided that such lot is combined with the building site and all potential for residential development on such lot is extinguished or removed.

2.

Procedural Requirements.

a.

Any development requiring a building permit on a lot having a net area less than 6,000 square feet shall be subject to a Ministerial Site Plan Review (Chapter 22.186) application.

b.

Any modification of development standards shall be considered only through a Variance (Chapter 22.194) application. The maximum gross structural area as determined by the slope intensity formula shall not be subject to modification.
