[Ord. No. 99-1 §1(24-26), 1-11-1999]
The quality of design of the urban area is dependent on the quality of design of the individual plats and subdivisions that compose it. Therefore, the design of each plat shall be prepared in accordance with the objectives established by the adopted City plan for land use, traffic circulation and utility services. The arrangement of lots and blocks and the street system shall be designated to make the most advantageous use of existing topography and natural physical features including tree masses and large individual trees. Adjacent properties should be considered in the plat design and shall not be landlocked.
[CC 1999 §23-11; Ord. No. 76-8 §2, 2-23-1976]
Prior to the acceptance by the City of new streets constructed within the corporate limits of the City or in adjacent areas anticipated or proposed to be annexed to the corporate limits of the City, the new streets, when constructed, shall meet certain minimum requirements as set forth in this Chapter.
[Ord. No. 99-1 §1(24-27), 1-11-1999]
A. 
Length. Intersecting streets, which determine block lengths, shall be provided at such intervals as to provide adequate access and to meet existing streets in the neighborhood. In residential districts where no existing plats are recorded, the blocks shall not exceed one thousand two hundred (1,200) feet in length except where topography or other conditions justify a departure from this maximum. In blocks longer than eight hundred (800) feet, pedestrian ways or easements through the block may be required near the center of the block by the Planning and Zoning Commission. Such pedestrian ways or easements shall have minimum width of ten (10) feet. Blocks for business use should normally not exceed six hundred (600) feet in length.
B. 
Widths. Residential plats, interior blocks shall have sufficient width to provide for two (2) tiers of lots of appropriate depths. Exceptions to this prescribed block width shall be permitted for exterior blocks which border the plat boundary or blocks adjacent to major streets, railroads or waterways. Blocks intended for commercial or industrial use shall be of such width and depth as may be considered most suitable for the prospective business.
C. 
Large Blocks. When a tract is platted for subdividing into larger than normal building lots and blocks, such parcels shall be so arranged as to permit the logical platting with provisions for adequate easements for streets and utilities.
[Ord. No. 99-1 §1(24-28), 1-11-1999]
A. 
Major Streets. Arterial and collector streets through plats shall conform with the City's major street plan. Wherever a plat abuts or is divided by a major street designated by the City plan, whether any part thereof has or has not been dedicated or used by the public, the developer shall dedicate any lands within such plat which are necessary to provide conformity with the major street plan. Such dedication shall be shown on the plat and the developer shall receive no compensation for such dedication.
B. 
Local Streets. Local streets shall be so designated to provide access to each lot or parcel of land and in a manner that will discourage use by through or non-local traffic.
C. 
Cul-de-sacs. Cul-de-sacs shall normally be no longer than five hundred (500) feet and shall terminate in circular paved space having a minimum radius of thirty-seven and one-half (37½) feet to outside of pavement or curb.
D. 
Right Angle Intersections. Under normal conditions, streets shall be laid out to intersect, as nearly as possible, at right angles. Where topography or other conditions justify a variation from the right angle intersection, the minimum angle shall be seventy degrees (70°).
E. 
Frontage Roads. Whenever a plat abuts or contains an existing or proposed major street, railroad or non-residential land use, the Planning and Zoning Commission may require frontage roads, screen plantings, deep lots or such other treatment as may be necessary for adequate protection of residential properties and to afford separation of through and local traffic.
F. 
Half-Streets. Dedication of half-streets will not be approved, except where it is in conformity with the approved major street plan and is essential to the reasonable development of the plat.
G. 
Minimum Dimensions. All streets included in any plat, hereafter dedicated and accepted, shall not be less than the minimum dimensions for each classifications as follows:

H. 
Street Alignment. Minimum horizontal and vertical alignment on all streets, except in unusual cases, shall be as follows:
1. 
Horizontal alignment. Radii at the centerline:
Major streets - 300 feet
Local streets - 100 feet
A tangent shall be provided between all reversed curves to provide for a smooth flow of traffic.
2. 
Vertical alignment. All changes in street grade shall be connected by vertical curves of such length as to provide for desirable sight distance.
I. 
Street Jogs. Streets with centerline offsets of less than one hundred fifty (150) feet shall be avoided.
J. 
Street Names. Street names shall not duplicate or be similar so as to be confused with the names of existing streets. Streets that are obviously in alignment with existing streets shall bear the same names. Street names shall not be the last name of living persons.
K. 
Adjoining Street System. If where the plat to be submitted includes only part of the tract owned or intended for development by the developer, a tentative plan of a proposed future street system for unplatted portion shall be prepared and submitted by the developer. Where it is obvious a street from another development should or could continue across the planned development, the plan shall provide for continuation of this street through the development.

All work must be done in a workmanlike manner and must be approved in writing by the City Engineer prior to acceptance by the City Council.

[Ord. No. 99-1 §1(24-29), 1-11-1999]
Alleys shall be provided in commercial and industrial districts, except that the requirements may be waived where other definite and assured provisions are made for service access to off-street loading and unloading areas and to off-street parking area consistent with and adequate for the uses proposed. Dead-end alleys shall be avoided wherever possible. Alleys may be required in certain residential areas. Alleys shall have a minimum width of twenty (20) feet.
[Ord. No. 99-1 §1(24-30), 1-11-1999]
Permanent utility easements acceptable to the City shall be provided, along streets and in such other areas as necessary to serve the area being developed and for future developments or needs of the City, through each block to logically serve every future lot or parcel. When utility easements cross streets, they shall align for at least fifty (50) feet on either side of the street right-of-way. All utility easements shall be at least fifteen (15) feet wide. Utility easement requirements may be waived by the Planning and Zoning Commission with concurrence of Chillicothe Municipal Utilities when alleys are provided for the placement of utility services.
[Ord. No. 99-1 §1(24-31), 1-11-1999]
Drainage easements shall be required in addition to other easements where a plat is crossed by a watercourse, drainage channel, stream or where required by the City Engineer to provide adequate drainage. All storm drainage shall be in accordance with the City's storm drainage management ordinance.
[Ord. No. 99-1 §1(24-32), 1-11-1999]
All developers are urged to consider the dedication of land for park, recreation and public use. When the City plan indicates a park, playground or school in a proposed plat, the developer shall duly consider the public needs and reserve such sites until the appropriate public boards have had an opportunity to negotiate terms of purchase, trade, dedication or any combination thereof with the developer.
[Ord. No. 99-1 §1(24-33), 1-11-1999]
A. 
Every lot shall be designed to provide a satisfactory and desirable building site and shall abut on a street and a utility easement.

C. 
The minimum lot depth shall be one hundred (100) feet, except where additional depth is required either by the zoning regulations or the lack of public utilities, water or sewer.
D. 
Minimum area shall be subject to the zoning regulations of the district in which the subdivision is located.

All side lot lines shall bear sixty degrees (60°) to ninety degrees (90°) from the street right-of-way line on a straight street or from a perpendicular of the tangent of a curved street.
F. 
Corner lots, in residential subdivisions, shall have additional width or depth in order that the same setback on both streets may be observed.
G. 
Double frontage lots shall be avoided unless, in the opinion of the Planning and Zoning Commission, a variation to this rule will give better street alignment and lot arrangement.
H. 
Residential lots shall front upon local streets or frontage roads rather than major streets whenever possible.
I.
