§ 174-21. Street system layout.

A. 

General.

(1) 

Streets shall be constructed to provide adequate means of access to each lot of a subdivision, § 220-9D of the Town Code.

(2) 

Design and construction of streets and related improvements shall be in accordance with the standards and specifications described in the Town of Canandaigua Site Design and Development Criteria, which are incorporated herein by reference.

(3) 

Streets and alleys shall be graded, surfaced and improved to the grades and dimensions shown on plats, profiles and cross-sections submitted by the applicant and approved by the Planning Board, Town Engineer and Town Highway and Water Superintendent.

(4) 

The location of all major streets in the proposed subdivision shall conform in general alignment to the adopted plans of the Town of Canandaigua.

(5) 

Where a subdivision abuts or contains a major traffic street, the Planning Board may require intermediate access streets, reverse-frontage lots or other treatments that will provide a reduction in the number of intersections with the major street and reasonable separation of local and through traffic.

(6) 

Minor streets shall be laid out to discourage through traffic, although provisions for street connections into and from adjacent areas will generally be required.

(7) 

Proposed street layouts shall generally provide for the continuation or projection of existing streets in the surrounding area and for access to adjoining properties unless the Planning Board finds such extension undesirable for specific reasons of topography or design.

(8) 

Adequate street rights-of-way providing future points of access shall be provided as necessary where lots in the proposal are large enough to permit resubdivision or if a portion of the tract is not subdivided.

(9) 

Streets shall be so related to the topography as to produce usable lots and reasonable grades.

(10) 

Where a subdivision abuts or contains an existing or proposed major traffic street, the Planning Board may require marginal access streets, rear service alleys, reverse-frontage lots or such other design elements as will provide protection for abutting properties, reduction in the number of intersections with the major street and separation of local and through traffic.

(11) 

New half or partial streets will not be permitted.

(12) 

Wherever a tract to be subdivided borders an existing or approved half or partial street, the balance of the street shall be plotted within such tract.

(13) 

New reserve strips, including those controlling access to streets, shall be avoided.

(14) 

Unless future extension is clearly impractical or found otherwise undesirable by the Planning Board, a street right-of-way of the same width as the street extend property lines of surrounding properties in such a way as to permit access into adjoining tracts.

(15) 

Street signs. Permanent street signs, of the same specifications as those of the Town Highway Department, shall be erected at each intersection by the Highway Department and paid for by the developer. The last word in the name of a private road shall be "drive."

B. 

Intersections.

(1) 

Streets shall be laid out to intersect as nearly as possible at right angles. No street shall intersect another at an angle of less than 75°.

(2) 

Multiple intersections involving a junction of more than two streets shall be avoided.

(3) 

Streets entering opposite sides of another street shall be laid out either directly opposite one another or with a minimum offset of 250 feet between their center lines.

(4) 

Where a subdivision abuts or contains an existing street of inadequate right-of-way width, additional right-of-way width will be required.

C. 

Alleys, culs-de-sac and dead-end streets.

(1) 

Alleys are prohibited in residential developments. In commercial or industrial districts, alleys shall be a minimum width of 22 feet. Where such alleys dead-end, they shall be provided with a turnaround having an outside roadway diameter to allow emergency vehicle access.

(2) 

Cul-de-sac streets, permanently designed as such, should not exceed 1,000 feet in length and shall be designed as noted in Appendixes G, H, H — 2 and H — 3 of the Site Design and Development Criteria.

Editor's Note: The Site Design and Development Criteria are available in the Town offices or through the Town's online version of the Code (eCode360®).

(3) 

Dead-end streets shall not be approved except when designed as stubs, with temporary "K" turnarounds to permit future street extension into adjoining tracts, or when designed as a cul-de-sac.

(4) 

Temporary hammerhead turnarounds shall be constructed to Town road specifications.

D. 

Haul roads. Haul roads may be required by the Planning Board, when applicable upon review with the Town Highway Superintendent, Town Board and Town Engineer. Performance bonds may also be considered as an option in lieu of construction of a haul road for necessary repair and maintenance of existing public roads.
