Any street plan requirements, water system, irrigation system, sewer system, or stormwater system shall be designed in accordance with the adopted city design and construction standards and specifications for public work improvements. Any alleys, easements, blocks, lots, building materials, roof pitch, public sites and open spaces within any proposed plat or development shall be designed in accordance with the following provisions:
A. Alleys shall be provided in commercial and industrial districts, except that the city may waive this requirement where other definite and assured provision is made for service access, such as off-street loading, unloading and parking consistent with and adequate for the uses proposed:
1. The minimum width of an alley shall be 20 feet;
2. Alley intersections and sharp changes in alignment shall be avoided, but where necessary corners shall be cut off sufficiently to permit safe vehicular movement; and
3. Dead-end alleys shall be avoided where possible, but, if unavoidable, may be approved with adequate emergency vehicle turnaround facilities at the dead-end.
B. Easements across lots or centered on rear or side lot lines shall be provided for utilities on an as needed basis:
1. Where a subdivision is traversed by a watercourse, drainage way, channel or stream, there shall be shown a stormwater or drainage easement conforming substantially to the lines of such watercourse, and such further width for construction, or maintenance, or both, as will be adequate for the purpose. Parallel streets or parkways may be required in connection therewith; and
2. A 10-foot pedestrian walking easement, parallel and adjacent to the water's edge at any given time, shall be provided on natural streams and creeks along or within a proposed subdivision. If a stream or creek traverses the interior of a subdivision, walk easements shall be provided on both sides of the natural stream or creek.
C. Block lengths and widths shall conform to the most advantageous development of adjoining areas and the entire neighborhood; provide conformity with the comprehensive plan; consider topographic constraints, lot size, critical areas, proposed land use, traffic flow; and the following standards:
The lengths, widths and shapes of blocks shall be determined with due regard 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;
3. Limitations and opportunities of topography;
4. Block length shall not exceed 1,000 feet; and
5. Pedestrian crosswalks, not less than 10 feet wide, may be required where deemed essential to provide circulation or access to schools, playgrounds, shopping centers, transportation and other commercial and community facilities.
a. Block lengths shall not exceed a maximum of 1,000 feet and a minimum of 200 feet between street lines. The public works director is vested with the authority to vary these standards if circumstances such as topographic conditions or present lot configurations exist that prevent the use of these standards. The public works director shall determine that varying these standards would not adversely affect adjacent properties.
b. The width of blocks shall be sufficient to allow for two tiers of lots with depths consistent with the type of land use proposed. The width shall not be less than 140 feet or the sum of two lot depths, except one tier of lots is encouraged between a residential street and an arterial street. The public works director is vested with the authority to vary these standards if circumstances such as topographic conditions or present lot configurations exist that prevent the use of these standards. The public works director shall determine that varying these standards would not adversely affect adjacent properties.
c. For lots with access provided by cul-de-sacs or looped streets, the standards noted in this section may be modified by the public works director to require block lengths and widths that lend themselves to later resubdivide in accordance with the standards prescribed in this chapter, ZMC Title
15 and the Zillah comprehensive plan.
D. The lot size, width, depth, shape and orientation shall be in accordance with the applicable zoning laws:
1. Corner lots for residential use shall have extra width to permit appropriate building setback from and orientation to both streets;
2. The subdividing of the land shall be such as to provide, by means of a public street, or approved private street, each lot with satisfactory access to an existing public street; and
3. Double frontage and reverse frontage lots should be avoided except where essential to provide separation of residential development from traffic arteries or to overcome specific disadvantages of topography and orientation. An easement of at least eight feet shall be provided along the line of lots abutting such a traffic artery.
E. City park facilities shall be centralized in a few locations and should not be located in locations throughout the city. Numerous small locations are inefficient in providing the care and maintenance of the parks. As part of Chapter
13.38 ZMC, or herein amended, funds shall be collected at the same time as the purchase of a city building permit. The monies received as a result of said developer fees shall be utilized by the city of Zillah for the acquisition of or improvement to park grounds and open spaces within the city limits of Zillah. Said fees imposed shall be collected prior to the issuance of a building permit.
F. Metal or aluminum siding buildings meeting the design requirements and spirit of the Old World design standards will be allowed in the commercial (C-1) or commercial-tourism (C-T) zones located within the boundaries designated on the design district maps 1 and 2 of the city adopted Old World design standards.
G. Except for multifamily structures, the following design standards shall apply to all newly constructed or newly placed dwellings in the R-1 and SR zones:
1. The main roof of all dwellings shall have a minimum 5:12 pitch; except dwellings with less than a 5:12 pitch legally established as of the effective date of the zoning code shall be permitted to be rebuilt, altered, enlarged or remodeled without the roof being changed to a 5:12 pitch.
