(a) General Street Design.
(1) The arrangement, character, width, grade, construction and location of all streets shall conform to the comprehensive land use plan, or other applicable street plans, for the Village that are in effect at the time of final plat submission.
(2) The street layout shall provide access to all lots and parcels of land within the subdivision.
(3) The applicant shall provide within the boundaries of the subdivision plat the necessary right-of-way for the widening, continuance or alignment of such streets in conformity with the comprehensive plan or other applicable street plans.
(4) Offset street intersections shall be avoided whenever possible.
(5) Where practical, the arrangement of streets in new subdivisions shall make provision for the continuation of existing streets in adjoining areas.
(6) A street that is not constructed to Village standards will not be accepted by the Village for dedication as a public street.
(7) Proposed streets shall be adjusted to the contour of the land so as to produce usable lots and streets of reasonable gradient.
(8) A street that is not constructed to Village standards will not be accepted by the Village for dedication as a public street.
(9) Streets within a subdivision which are reasonably expected to be subject to flooding shall not be accepted by the Village. All streets must be located at elevations which will make them flood-free, in order that no portion of the subdivision would become isolated by floods.
(10) In the interest of public safety, and as a matter of policy, all points of ingress and egress shall be located as far as possible from the intersection of two or more major arterial streets or highways.
(b) Traffic Control Devices. The applicant shall provide all traffic control devices for the proposed development, including, but not limited to, traffic signals, signs, pavement markings and the like. Refer to the Ohio Manual of Uniform Traffic Control Devices (OMUTC) for details of the devices to be used, and, in some cases, warrants for their use.
(c) Street Signage. All new subdivisions shall be required to install the street signage within each phase on all public and private streets. The signage shall be installed prior to acceptance by the Village, and the road being open to vehicular traffic. The signage must be shown on the improvement plans/site plans as submitted for review by the Planning Commission.
(d) Street Names and Numbering.
(1) Street names shall be selected that will not duplicate or be confused with the names of existing streets in the Village of Centerburg and Knox County, irrespective of modifying terms such as street, avenue, boulevard, etc. Streets that are or will eventually be continuations of existing or platted streets shall be named the same. Street names shall be included on the preliminary plat and final plat.
(2) Street names shall not be confusing, offensive, or otherwise named in such a manner as to hinder safe or efficient travel.
(3) When a new street is a direct extension of an existing street, the name shall remain the same.
(4) Address numbers shall be assigned by the Village in accordance with the current numbering system.
(e) General Street and Right-of-Way Design Standards.
(1) Proposed street classifications shall be designated (i.e., local, principal collector, arterial, etc.) on all plats, based on their proposed functions and the recommendation of any approved street plans. The physical and geometric design of streets shall be based upon these designations in adapting the proposed streets to the existing terrain and soils.
(2) The standards of the American Association of State Highway and Transportation Officials (AASHTO), as published in A Policy on Geometric Design of Highways and Streets, 1984; A Policy on Design Standards for Stopping Sight Distances, 1971; and subsequent publications modifying those standards by AASHTO, in effect at the time of final plat submission, shall govern the design of subdivision streets and abutting Village, county and township roads. The "Desirable Sight Distance Values" will govern in all but the most unusual instances, and any lesser values must be recommended by the Village Administrator before the preliminary design plan is approved by the Planning Commission.
(3) The pavement design shall be calculated and submitted by an Ohio registered engineer with the preliminary plat approval.
(4) The applicant shall be responsible for all required improvements, including the required pavement width measured from back-to-back of curbs on an undivided street.
(5) When developing along one side of an existing street or roadway which is included in any approved street plans, the applicant shall be responsible for one curb, the pavement widening to thoroughfare width of his or her side, all necessary adjustments to existing pavement, and storm drainage for the street in accordance with an agreement with the Village Administrator. Where sight distances or other engineering requirements make it imperative, the pavement adjustment responsibility shall include the replacement of up to the entire existing pavement, also in accordance with an agreement with the Village Administrator.

All Other Local Streets | 50 | 33 | 30 | Not Applicable | 8 | 0.5 |
NOTES: [1] Pavement width is measured back of curb to back of curb. [2] Where marginal access streets are used to provide access to existing or proposed arterials, improvements on those thoroughfares may be waived by the Village Administrator | ||||||
(6) Table 1119-2 establishes the standards for horizontal curves, reverse curves, sight distances for each street type.
Table 1119-2: Street Curve and Sight Distance Standards | |||
Type of Street | Horizontal Curve | Reverse Curve | Sight Distance |
Minimum Radius (Feet) | Required Tangent (Feet) | Minimum (Feet) | |
Major Arterial Street | 400 | 250 | 450 |
Minor Arterial Street | 400 | 150 | 350 |
Collector Street | 300 | 100 | 275 |
Local Street | 200 | 50 | 200 |
(7) Vertical Alignment.
A. All changes in grades shall be connected by vertical curves of a minimum length in feet equal to thirty (30) times the algebraic difference in the rate of change of grade expressed in feet per 100 feet. Longer vertical curves shall be used when needed for sight distances as determined by the design engineer and approved by the Village Administrator.
B. No street grade shall be less than 0.4 percent and on stop streets, the grade shall not exceed two percent positive or three percent negative within 100 feet of an intersection with local streets or 150 feet for all other intersections, unless otherwise approved by the Village Administrator. The positive is considered going up from the intersection and the negative is going down from the intersection.
C. Whenever the applicant changes the grade of an existing street outside the limits of the development, and the grade change requires adjustment to meet existing improvements (streets, driveways, walks, and the like), such adjustments shall be the responsibility of the applicant, as approved by the Village Administrator.
(f) Special Street Types and Street Requirements. The following requirements shall apply to special street types or under the specified circumstances:
(1) Temporary Dead-End Streets.
A. Temporary dead-end streets shall be permitted only where there are future plans to continue the street into another phase of the subdivision or into an adjacent, future subdivision. In such cases, a temporary turnaround shall be provided with a design approved by the Village Administrator.
B. Provisions for maintenance and the removal of the temporary dead-end street shall be required of any additional plat approvals.
C. Temporary dead-end streets longer than 600 feet are prohibited.
D. A "T" turnaround (temporary only) may be permitted in-lieu of a cul-de-sac that is required for permanent dead-end streets. Such turnarounds shall be designed to allow vehicles to turn around with only one backing-up movement. See Figure 1119-A. The turnaround area shall be the same width as the street it abuts and shall be at least seventy-five (75) feet long.
Figure 1119-A: Illustrative example of a temporary "T" turnaround.
E. If a dead-end street extends one lot depth or less past a street intersection, a "T" turnaround will not be required.
(2) Permanent Dead-End Streets.
A. Permanent dead-end streets are prohibited unless they include a turnaround (cul-de-sac) in accordance with this subsection.
B. Permanent dead-end streets shall not exceed 600 feet in length as measured from the centerline of the intersecting street to the center of the turn-around. Permanent dead-end streets may be longer where unique topographic or other physical conditions exist making a through street impractical.
C. All permanent dead-end streets shall be designed with a turning circle having an outside pavement diameter (curb face to curb face) of at least eighty (80) feet.
(3) Streets for Nonresidential Subdivisions.
A. Streets serving nonresidential developments (e.g., commercial or industrial) and accessory parking areas shall be planned to connect with collector or arterial streets so as not to generate traffic on local access streets.
B. The Village Administrator may require local access streets (frontage streets) that run parallel to an arterial or collector street to provide maximum safety and convenience.
(4) Half-Streets. The dedication of new half-streets shall not be permitted. Where a dedicated or platted half-street exists adjacent to the tract being subdivided, the other half shall be platted.
(5) Private Streets.
A. Private streets are discouraged.
B. Where constructed, a private street shall be constructed to the minimum standard of a public street in accordance with this code.
C. The Village shall not be responsible for maintenance, snow plowing, cleaning, or provision of similar public street services for private streets.
D. Property owners abutting a private street may request that the Village accept the street as a public street dedication at a later date, but the Village shall not be required to accept such dedication.
E. In no instance shall the Village accept a private street as a public dedication until such street is shown to meet all applicable street design standards required for public streets in this code.
