§ 13-525. Design.

(a)

Block standards. The following standards shall be observed for the design of blocks (lot grouping) in non-exempt subdivisions.

(1)

General considerations. The lengths, widths and shapes of blocks shall be determined with due regard to:

a.

Provision of adequate building sites suitable to the special needs of the type of use proposed.

b.

Zoning requirements as to required lot areas and dimensions.

c.

Need for convenient access, circulation, control and safety of street traffic.

d.

Opportunities and limitations of topography.

(2)

Residential block length. In general, intersecting streets which determine block length shall be provided at such intervals as necessary to meet existing street patterns, topography, and requirements for safe and convenient vehicular and pedestrian circulation. Generally, blocks should not be less than two hundred (200) feet, or more than two thousand (2,000) feet, in length, unless no other practicable alternative is available.

(3)

Non-residential block length. Blocks intended for non-residential uses shall be of such length, width and other design as the commission finds necessary for the proposed use, including adequate provisions for off-street parking, loading and unloading, and limitations and control of vehicular access points to adjacent streets.

(4)

Recreational vehicle parks. Blocks, sections or areas within the RV parks shall contain only one (1) class of RV sites.

(b)

General lot/parcel standards.

(1)

Minimum lot/parcel size. The following standards shall be adhered to for the design of lots in subdivisions.

a.

Minimum area. Subject to other provisions of this chapter, all lots or parcels in the respective land use zones shall have at least the amount of acreage or square footage indicated in Tables 13-423A and 425A.

b.

Minimum width. Tables 13-423A and 425A indicate the minimum lot widths, at the front setback line, that are required in each land use zone. Notwithstanding the lot width at the setback line, no lot shall be less than twenty-five (25) feet in width at the street or easement right-of-way line.

(2)

Subdivision of non-residential land.

a.

Commercial/industrial/institutional parcels with or without shared infrastructure shall be subdivided in accordance with section 13-350.

b.

Each such parcel created must comply with all relevant requirements of this chapter, such as location, size, access requirements and setbacks.

c.

A development agreement for maintenance and construction of necessary infrastructure may be required at time of engineering plan review.

d.

A two (2) year performance guarantee, acceptable to the board for one hundred (100) percent of the cost of any improvements to be constructed within county road rights-of-way or easements if required of applicants other than government and quasi-government entities.

e.

Plans for development permits for each parcel must be submitted in accordance with relevant provisions of this chapter.

(c)

Lot/tract standards in non-exempt subdivisions:

(1)

Street access. Each lot created and intended for occupancy shall either abut on a road in the county or state system of maintained roads, or abut on a private road, constructed and maintained to county standards, which connects to such county or state roads. The access shall be of such a nature as to permit reasonable means of ingress and egress for emergency vehicles as well as for all those likely to need or desire access to the property in its intended use.

(2)

Usable width. No parcel may be created that is so narrow or otherwise so irregularly shaped that it would be impracticable to construct on it a building that 1) could be used for purposes that are permissible in that land use zone, and 2) could satisfy any applicable setback requirements for that district.

(3)

Separation. Consideration shall be given to lot orientation with respect to the separation of incompatible land uses. Residential lots which face commercial or industrial areas, or which face major streets shall be avoided if practicable. Mixed uses within a town center or RPUD are encouraged.

(4)

Corner lots. Corner lots shall be of sufficient size to permit compliance with the required minimum setbacks from all property lines which abut streets or easements.

(5)

Lot lines. When possible, side lot lines shall be at right angles to straight street center lines and radial to curved center lines. When possible, rear lot lines shall be straight lines. Each lot/site property line shall be clearly defined by permanent visible markers.

(6)

Double lot frontage. Double lot frontage shall only be permitted where it shall be found necessary to separate a development from arterial streets or collectors or to overcome specific disadvantages of topography, orientation and property size. Access will be provided via the roadway of lesser classification.

(7)

Minimum buildable depth. Lots created after the effective date of this chapter shall, as a minimum, conform to lot area and width requirements set forth for the land use zone in which the development is located. Except for PUDs, no lot shall have a buildable area of less than thirty (30) feet between the front and rear, and side setback lines.

(8)

Remnants. All portions of the property being subdivided shall be placed in lots, streets or tracts so that remnants and landlocked areas are not created. If remnants of land do appear during the design process, and have no apparent future use which can be properly controlled, they shall be incorporated into the lots of the proposed design.

(9)

Area above high water. As a minimum, the proposed subdivision design shall provide for all lots to have a contiguous natural ground area, above the seasonal high-water elevation, of one-half (½) acre or the minimum lot size required by the applicable land use zone, whichever is less.

(10)

Useable area. All lots/parcels/sites shall provide stable and dry structure and parking areas of sufficient size to accommodate the proposed use.

(11)

RVPUD. All Class A RV sites shall be located on a park roadway constructed and maintained to minor local road standards.
