(Ord. 496 § 7.0, 1999: Ord. 462 § 7.0, 1998)
16.12.020 - Lot and block design standards.
A. Block Dimensions. The lengths, widths and shapes of blocks shall be determined with regard given to: (1) provision of adequate
building sites suitable to the special needs of the type of use contemplated; (2) needs for convenient access, circulation,
control and safety of street traffic; and (3) limitations and opportunities of topography.
1. Block lengths shall not exceed one thousand (1,000) feet.
2. Pedestrian crosswalks, not less than ten (10) feet wide, may be required where deemed essential to provide circulation or
access to schools, playgrounds, shopping centers, transportation and other community facilities. Such crosswalks may be required
to be marked and maintained annually.
B. Lot Dimensions. Lot size, width, depth, shape and orientation shall conform to the zoning standards applicable to the area
within which the property is located. Sufficient area for the proposed use, setbacks and other area requirements shall be
accommodated.
1. Through Lot, also known as Double Frontage Lot.
a. No residential lots shall have road frontage along two opposite boundaries unless justified by topographical features or the
need to provide separation of the lots from arterials, railways, commercial activities or similar uses.
b. An easement of at least ten (10) feet, and across which there shall be no right of access, shall be provided along the line
of lots abutting the arterial or other area of disadvantageous use.
2. Flag Lots. Flag lots, as defined in Section 16.04.100, may be permitted to accommodate buildable area which does not have
standard frontage on a public street and where access to the buildable area is not feasible by any other standard land division
method or lot design. In general, flag lots are only allowed to encourage infill development, preserve natural areas or to
allow development of land-locked (buildable) areas. The narrow (access) portion of the flag lot shall not be used to grant
access to other property not having frontage on a public street.
3. Lot Access/Frontage
a. Every lot shall be provided with frontage on a public street or approved private lane as provided in Section 16.12.060 connecting
to an existing public street.
b. The lot frontage of a flag lot as provided in subsection (D)(2) of this section, shall be at least twenty (20) feet in width.
The building site portion of the flag lot shall meet the dimensional standards of the applicable zone. The length, width and
improvement of the access to the building site shall comply with the requirements of Yakima County Fire District No. 3.
c. Developments abutting principal arterial streets shall be designed to provide access from interior streets. Access to arterial
streets by individual lots shall only be permitted with specific findings demonstrating compelling need based on lot size,
shape, topography or other property characteristics and addressing public safety.
d. Corner lots for residential use shall have extra width to permit appropriate building setback from and orientation to both
streets.
4. Cul-de-sac (Turnaround) Lots.
a. No more than four lots may be located exclusively on the turnaround of a cul-de-sac.
b. The minimum lot width for lots on cul-de-sac turnarounds shall be fifty (50) feet measured at the required setback line.
5. Parks and Recreation Areas. Pursuant to RCW 58.17.110 and related statutes, the town council may require subdivisions to designate
up to five percent of their land area exclusive of streets, as either private or public parks and recreational areas, the
nature of which shall be clearly indicated on the plat; provided, not less than a contiguous minimum of ten thousand (10,000)
square feet shall be so allocated. The acquisition of land required by the town for public parks or recreational areas, other
than streets and alleys, shall be obtained by deed from the developer prior to final approval of the plat. As an alternative
to dedication of public parks and recreational areas, the developer may be required to contribute to the town for park purposes
to benefit the area up to five percent of the developed value of the lots to be sold in the plat. Payment of cash in lieu
of land for park purposes in the area shall be made by the developer to the town before final approval is given. The moneys
to be exclusively used for park development purposes, shall be deposited in a special park fund to be dedicated by the town
to benefit the area platted.
