In laying out a subdivision, the subdivider shall comply with the following general principles and requirements:
1. The layout must conform to a transportation plan adopted by the village, other parts of the adopted community development plan and other adopted regulations of the village. Where a proposed park, playground or other recreational area, proposed school site or public ground, shown on the adopted community development plan, is located in whole or in part within the proposed subdivision, such proposed public ground or part, if not dedicated to the board of education or other public agency, must be reserved and no action taken on the subdivision for a period of not less than ninety (90) days to allow the village board or other public agency the opportunity to consider and take action toward acquisition of such public ground or park by purchase or other means. If the responsible agency does not take action to acquire such land, the subdivider may then use the land for any purpose permitted.
2. Where considered desirable by the subdivider and held appropriate by the village board, open spaces suitably located and of adequate size for parks, playgrounds or other recreational purposes for local or neighborhood use may be provided for in the design of the proposed subdivision, and if not dedicated to the public and accepted by the appropriate public body, may be reserved for the common use of all property owners in the proposed subdivision by covenant in the deeds.
(B) The Street And Block Layout:
1. The street layout of the subdivision shall be in general conformity with a plan for the most advantageous development of adjoining and nearby areas.
(a) Where appropriate to the design, proposed streets shall be continuous and in alignment with existing, planned or platted streets with which they are to connect.
(b) Proposed streets shall be extended to the boundary lines of the tract to be subdivided, unless prevented by topography or other physical conditions, or unless, in the opinion of the village board, such extension is not necessary or desirable for the coordination of the layout of the subdivision with existing layouts or the most advantageous future development of adjacent tracts. Cul-de-sacs of reasonable length will be approved where topography necessitates or where they appropriate for the type of development contemplated.
(c) Proposed streets shall intersect one another as nearly at right angles as topography and other limiting factors of good design permit.
(d) Wherever there exists adjoining the tract to be subdivided a dedicated or platted and recorded half width street or alley, the other half width of such street or alley shall be platted.
(e) Alleys shall ordinarily be platted: 1) in the rear of all lots to be used for business; and 2) in the rear of residential lots fronting on primary thoroughfares (unless service roads are provided in front thereof) as a means of safe access to such lots.
2. Blocks shall have sufficient width to provide for two (2) tiers of lots at least one hundred feet (100') in depth, unless, in the opinion of the board, prevented by exceptional topography or other physical conditions.
(a) The lengths of blocks shall be such as are appropriate, in the opinion of the village board, for the locality and the type of development contemplated, but shall not exceed one thousand two hundred feet (1,200').
(b) In any block over seven hundred feet (700') in length, the board may require that a crosswalk or pedestrianway, not less than ten feet (10') wide, be provided near the center and entirely across such block.
(c) Cul-de-sacs shall not exceed five hundred feet (500') in length measured along the centerline from the intersection at origin through the end of the circle to the end of the right of way.
(C) Minimum Right Of Way Widths Of Streets, Alleys And Easements For Utilities:
1. Street: Not less than sixty feet (60') wide in any case.
2. Street And Cul-De-Sac: The village board in its discretion may permit a street with curb and gutter and fifty feet (50') in width. All dead-end streets shall terminate in a circular turnaround having a minimum right of way diameter of one hundred feet (100').
3. Alleys And Service Drives: Twenty feet (20') wide.
4. Easements for utilities, where required, should be at least ten feet (10') wide centered on rear or side lot lines.
(D) Minimum Surface Widths: The portion of the surface required to be installed at the subdivider's expense shall be as follows:
1. Streets designated on an adopted transportation plan or approved by the village board. Overall surface widths shall be as designated by an adopted transportation plan or by the village board, and the differences, if any, between the cost of the portion to be provided at the expense of the subdivider and that of the total width designated by the transportation plan or the village board shall be borne by the municipality, unless it shall be determined by the village board that such greater width will benefit the subdivider in proportion to its cost. The surface of a turning circle at the end of a cul-de-sac shall have a minimum outside diameter of eighty feet (80'). A "T" or "Y" shaped surfaced space, when approved by the board may be used as a temporary measure at the end of a dead-end street until such time as the street is continued.
2. Alleys and service drives shall be surfaced to a width of sixteen feet (16').
(E) Street Grades, Curves And Sight Distances:
1. The grades of streets shall not be less than five-tenths percent (0.5%) nor exceed the following:
(a) Streets, designated as such on an adopted transportation plan or as approved by the village board: Five percent (5%) unless prevented by topography.
(b) Service drives and alleys: Ten percent (10%).
(c) Pedestrianways or crosswalks: Twenty percent (20%), unless steps of an acceptable design are to be constructed.
2. All changes in street grades above one percent (1%) shall be connected by vertical curves of a minimum length equal to thirty (30) times the algebraic difference in the rate of grade for subsection (E)1(a) of this section and one-half (1/2) of this minimum for all other streets.
3. The radii of curvature on the centerline shall not be less than the following:
(a) Streets: Three hundred fifty feet (350').
(b) Service drives and alleys: One hundred fifty feet (150').
(F) Intersections: Streets shall intersect as close to a ninety degree (90°) angle as possible.
1. The size, shape and orientation of lots shall be appropriate for the location of the proposed subdivision and for the type of development contemplated.
2. Excessive depth in relation to width ordinarily shall be avoided.
3. Every lot shall abut on a public right of way dedicated for street purposes.
4. Lots for residential purposes shall be at least thirty-seven and five-tenths feet (37.5') wide at the front lot line and shall be adequate for a building of practicable width.
5. Lots larger than the minimum called for by health and land use regulations may be required where topographic or other considerations may limit the buildable or usable portion of such lots.
6. Corner lots for residential use ordinarily should be platted wider than interior lots in order to permit conformance with the required setbacks.
7. Residential lots fronting on highways, thoroughfares and parkways should have extra depth to permit deep setbacks for the buildings.
8. Double frontage lots and reversed frontage lots ordinarily should be avoided.
9. Side lot lines shall be approximately at right angles to the right of way line of the street on which the lot fronts.
10. Side lot lines on curved streets shall be radial to the right of way line of the street on which the lot fronts.
11. Lots not served by public sewer systems and/or public water systems shall meet all requirements established to protect public health.
(a) Lots lacking both services shall ordinarily be at least twenty thousand (20,000) square feet in size and at least one hundred twenty-five feet (125') wide at the building line.
(b) Lots having either public water or sewer shall be at least fifteen thousand (15,000) square feet in size and at least one hundred feet (100') wide at the building line.
(c) Lots having both services shall be at least seven thousand five hundred (7,500) square feet in size and at least seventy-five feet (75') wide at the building line.
(d) Percolation tests and related public health measures shall be used in all cases and the above stated minimum requirements may be modified upon report of appropriate state or county agencies.
(e) Lot sizes as stated in this chapter are subject to requirements of the zoning district in which they are located. (Ord. 296, 10-24-1972; amd. Ord. 779, 12-13-2022)
