A. General Provisions:
1. The subdivision of land, including the arrangement, character, extent, width, grade and location of all streets, alleys, or other land to be dedicated for public use, shall conform to the standards of this title and shall be considered in their relation to existing and planned streets, topographical conditions, to public convenience and safety, and in their appropriate relation to the proposed uses and densities of the land to be served by such streets. No extension of any existing streets or alleys shall be blocked or offset within the village or within one and one-half (11/2) miles of its corporate limits. Streets shall conform to the official plan of the village where possible, and shall not be planned so as to overburden existing streets by channeling excessive traffic onto existing streets. Private streets shall not be permitted unless approved as part of a planned unit development by the village board of trustees. Private streets shall be covered by a special service area (SSA) taxing authority or homeowners' association (HOA), which shall be structured to cover all maintenance costs.
2. Wherever the tract to be subdivided and/or developed borders on and will utilize existing street frontage, then said existing street frontage, including the existing pavement, should be fully improved by the developer in accordance with the requirements as specified in this title or by the village board. When a proposed subdivision utilizes an existing village of Winfield street, that proposed subdivision shall upgrade the existing street to meet the subdivision control ordinance provisions outlined herein.
3. Street alignment should respect the natural features of the site, should avoid excessive cuts or fills, and should preserve wooded areas, large trees, and wetlands wherever possible.
4. All streets shall be provided to afford convenient access to all lots within the subdivision, and shall front all lots, tracts and parcels.
5. If the tract of land proposed to be subdivided, or any part thereof, lies adjacent to a roadway over which the Illinois department of transportation, DuPage County highway department, or a township highway department has jurisdiction with respect to maintenance and upkeep thereof, and an entrance or entrances are desired from such street to lots, streets, roadways or alleys, in such proposed subdivision, the developer shall prepare and submit the appropriate permit application to said highway department. The permit application granting permission to obtain and construct such an entrance or entrances shall be submitted to the village engineer and reviewed prior to the submittal to the proper highway departments by the developer.
6. On primary and collector streets where traffic volume and safety considerations warrant or where required by other government authority having jurisdiction, paved acceleration, deceleration, passing and turning lanes shall be provided by the developer.
7. Residential streets shall be laid out so that their use by through traffic will be discouraged. When a traffic signal is warranted and required, each development shall escrow its proportionate share of that future signal cost, based upon traffic impact.
8. No street names may be used which will duplicate or be confused with the names of existing streets. The village retains the right to name all streets which shall be approved by the planning commission and the village board. Proposed streets which are obviously in alignment with or continuations of existing streets already named shall bear the name of such existing streets provided the continuation is in the same general direction. Street name signs of a type approved by the village board shall be provided by the developer/subdivider at all street intersections in accordance with detailed standards within this title.
9. Separation of entrances, as well as ingress/egress specific geometrics shall be per direction of the plan commission and village board, as recommended by the village engineer.

Standard Specifications: All new streets within the corporate limits of the Village of Winfield, dedicated or platted after the effective date of this title, shall be improved with roadway pavement including subgrade, subbase, base course, surface course, curb and gutter, and all other related work in accordance with this title and the latest edition of the "Standard Specifications for Road and Bridge Construction", Illinois Department of Transportation.
C. Location: Streets shall be located per the direction of the Village Board, with the recommendation of the staff and Plan Commission. Wherever such a planned street is located within a proposed subdivision, the street shall be designed and located in the place and with the width indicated for that street classification as shown on the Comprehensive Plan, or as defined by the Village Engineer. Where the street is not shown on the official Street Plan, the arrangement of streets in the subdivision shall:
1. Extend to existing adjoining streets, unless extension thereof would not be practical, and shall be located to coordinate with other proposed developments;
2. Provide for the continuation or appropriate projection of existing principal streets in surrounding area;
3. Conform to a plan for the area or neighborhood approved or adopted by the Village Board to meet a particular situation where topographical or other conditions make continuance or conformance to existing streets impracticable.
D. Abutting Planned Or Existing Highway Or Railroad:
1. Where a subdivision borders on or contains an existing or proposed primary street or railroad, the Village Board, upon recommendation of the Planning Commission, may require a frontage or reversed frontage road with screen planting contained in a nonaccess reservation, which shall have a minimum width of ten feet (10'), but actual width may increase if determined by recommendation of the Planning Commission and approved by the Village Board in order to provide adequate separation and screening from the primary street or railroad.
2.

If precipitation occurs and the subgrade becomes saturated before the base course is constructed, then said proof rolling shall be repeated.
If the subgrade compaction testing and proof rolling indicate unsuitable or unstable subgrade areas, then said unsuitable or unstable areas shall be removed and replaced with acceptable compacted granular material. Upon direction of the village engineer, designated areas of unstable subgrade shall be stabilized by installing the lime stabilization as approved by the village engineer.
