Subdivisions should be planned to take advantage of the topography of the land, to economize in the construction of drainage facilities, to reduce the amount of grading and to minimize the destruction of trees and topsoil.
If any portion of the land within the subdivision is subject to flooding or other hazards, due consideration shall be given to such problems in the design of the subdivision. Land subject to flooding and land otherwise uninhabitable shall not be planned for residential occupancy nor for such other uses that may increase danger to health, life or property or may aggravate the flood hazard.

A. 
Arrangement. The arrangement, character, extent, width and location of all roads shall conform to adopted land use and road plans and standards as established by the Town Engineer or Highway Superintendent. The design of proposed roads shall provide for both the continuation of existing roads and access to adjacent unplanned lands to that the entire area can be served with a coordinated road system.
B. 
Road classifications.
(1) 
Arterial roads shall be planned for continuation of movement of fast traffic between points of heavy traffic generation and from one section of the community to the other. They shall contain as few intersections with minor roads as possible. Such roads should traverse the community and should be spaced approximately one mile apart.
(2) 
Collector roads shall provide a traffic route from minor roads to arterial roads. Collector roads normally contain a relatively large number of intersections with minor roads and few intersections with arterial roads. These roads should be spaced at least 1/4 mile part.
(3) 
Minor roads shall provide direct access to each lot and shall be laid out so that their use by through traffic will be discouraged.
(4) 
Marginal access roads and reverse-frontage lots may be required to provide adequate and safe access to lots along such arterial roads.
C. 
Road right-of-way widths and grades.
(1) 
Widths and grades shall be as follows:

When roads are under the jurisdiction of the New York State Department of Public Works or the Cayuga County Highway Department, the respective agency will determine the width.
D. 
Half roads. Half roads shall be prohibited.
E. 
Cul-de-sac roads. Roads designed to be permanently cul-de-sac roads shall not be longer than 1,000 feet and shall be provided at the closed end with a turnaround having an outside pavement diameter of at least 150 feet.[1]

Editor's Note: Amended at time of adoption of Code; see Ch. 1, General Provisions, Art. I.
F. 
Corner radii. Property lines at road intersections shall be rounded with a radius of not less than 50 feet for arterial roads, 25 feet for collector roads and 15 feet for minor roads. Chords or cutoffs may be permitted in place of rounded corners.
G. 
Horizontal and vertical curves. Angles in the alignment of road lines shall be connected by a curve with a radius on the center line of not less than 200 feet for minor roads, 300 feet for collector roads and 500 feet for arterial roads.
H. 
Intersections. Roads shall be laid out to intersect as nearly as possible at right angles, and no road shall intersect any other road at an angle of less than 60°. Three-way stop intersections are encouraged, but in no event shall an intersection in excess of four roads be approved.
I. 
Road jogs. Road jogs with center-line offsets of less than 125 feet shall be prohibited.
A. 
Public utility easements. Public utility lines shall be buried wherever possible. The use of a common trench for public utilities is encouraged.
B. 
Drainage easements. Where a subdivision is traversed by a drainageway, a stormwater or drainage easement conforming substantially with the lines of such drainageway shall be provided. The easement shall be 20 feet wide and shall generally follow but not be centered upon rear and side lot lines.
A. 
Residential block lengths. The long dimension of a residential block shall not exceed 1,500 feet or less than 800 feet.
B. 
Pedestrian walkways. Pedestrian walkways not less than 10 feet wide shall be required across blocks where the Planning Board deems that pedestrian access to schools, playgrounds, shopping centers, transportation and other community facilities is necessary.
C. 
Commercial or industrial blocks. Blocks intended to be used for commercial or industrial purposes shall be designed specifically for such uses, with adequate space set aside for parking and loading facilities.
A. 
Land Use Ordinance conformance. The lot size, width, depth and minimum building setback lines shall conform to the regulations of the Town of Cato Land Use Ordinance.[1]
[1]
Editor's Note: See Ch. 76, Land Use.
B. 
Corner lots. Corner lots shall have extra width to permit appropriate building setback from and orientation to both roads.
C. 
Access to public roads. The subdividing of land shall provide each lot with access to an existing public road.
D. 
Double-frontage lots. Lots shall not be so laid out that they have frontage on more than one road except where the lots are adjacent to the intersection of two roads or where it is necessary to separate residential lots from arterial roads. Where double-frontage lots are created adjacent to arterial roads, a reserve strip along the arterial roads shall be deeded to the town. The plan shall state that there shall be no right of access across such reserve strip. The Planning Board may require that a six-foot-high, solid-board fence or masonry wall be constructed or that a ten-foot-wide planting screen be provided.
E. 
Lot lines. Lot lines shall be substantially at right angles or radial to road lines.
A. 
Public facilities. The design of the subdivision shall provide for parks, playgrounds, schools and other sites for public use as provided in § 98-28 of these regulations. Such public facilities shall conform to the Land Use Ordinance of the Town of Cato, New York.[1]

Editor's Note: See Ch. 76, Land Use.
B. 
Natural features. Due consideration shall be given to preserving outstanding natural features, such as scenic spots, water bodies or groves of trees. Dedication to and acceptance by a public agency is usually the best means of assuring their preservation.
