[2-28-2022 by Ord. No. 08-2022]

Where a land division abuts an existing temporary circular cul-de-sac or "T" turnaround and the Village Official Map includes extending the street ended by said temporary turnaround, the subdivider shall be responsible for the removal of the turnaround, reconstruction of the drainage and roadside ditches or curb and gutter as applicable, reinstallation of culverts, reconstruction of driveways, and restoration of all disturbed areas, and removing or vacating any portion of the street containing a temporary easement if applicable [see § 74-7.4(d)]. The Public Works Director will determine if existing culverts, if any, may be salvaged and reused.

§ 74-8.6 Curbs and gutters.

[2-28-2022 by Ord. No. 08-2022]

After the installation and the Village's inspection and approval of all utility and stormwater drainage improvements, the subdivider shall construct concrete curbs and gutters in accordance with plans and specifications approved by the Public Works Director. This requirement may be waived where a permanent rural street section has been approved by the Plan Commission. The cost of installation of all inside curbs and gutters for dual roadway pavements will be borne by the Village or the unit or agency of government having jurisdiction.

Curbs and gutters may be required on cul-de-sac landscape "islands" and on streets with steep topographical conditions. Openings in curbs for drainage may be allowed, upon approval of the Public Works Director, to accommodate green stormwater management measures such as drainage into street tree wells, rain gardens, infiltration trenches, or bioretention basins with underdrains. Wherever possible, provisions shall be made at the time of construction for driveway access curb cuts [unless "butterfly," "roll-face," or "mountable" type curbs are installed; then such curb cuts may not be necessary].

Curb ramps or openings shall be installed, where applicable, in accordance with the Americans with Disabilities Act Accessibility Guidelines, § 66.0909 of the Wisconsin Statutes, and as approved by the Public Works Director.

[2-28-2022 by Ord. No. 08-2022]

The subdivider shall construct a concrete sidewalk or asphalt path on one side of all frontage streets and on one or both sides of all other streets within the land division or condominium. Off-street paths may also be required by the Village. The construction of all sidewalks and paths shall be in accordance with plans and specifications approved by the Public Works Director. All such facilities shall be located within a dedicated public right-of-way or a public access easement. If located within a public access easement, said easement shall be at least 20 feet wide. The construction of all sidewalks and pedestrian/recreational paths, including bicycle facilities, shall be in accordance with plans and specifications approved by the Public Works Director and adopted pedestrian, bicycle, park, or recreational plans.

Wider than standard sidewalks or asphalt paths may be required by the Public Works Director in the vicinity of schools, commercial areas, and other places of public assembly. The Plan Commission may waive the requirement for sidewalks or paths upon a finding that such walks or paths are not required because of the provision of a separate network of pedestrian/recreational ways, low vehicular or pedestrian traffic volumes, or lot arrangement.

§ 74-8.9 Sanitary sewage disposal facilities.

[2-28-2022 by Ord. No. 08-2022]

The subdivider shall construct sanitary sewers in such a manner as to make adequate sanitary sewerage service available to each lot or unit within the land division or condominium. Where public sanitary sewer facilities are not available, the subdivider shall make provision for adequate POWTS specified by the Village, county, and state agencies concerned.

The subdivider shall install sewer laterals to the street right-of-way line. If, at the time of final platting, sanitary sewer facilities are not available to the plat, but will become available within a period of five years from the date of plat recording, the subdivider shall install or cause to be installed sanitary sewers and sewer laterals to the street lot line in accordance with this section and shall cap all laterals as may be specified by the Public Works Director.

The subdivider shall assume the cost of installing all sanitary sewers, laterals, and appurtenances required to serve the land division or condominium development proposed. If sewers greater than eight inches in diameter are required to accommodate sewage flows originating from outside of the proposed development, the cost of such larger sewers shall be prorated either in proportion to the ratio of the total area of the land division or condominium development to the total tributary drainage area to be served by such larger sewer, or in proportion to the contributing sewage flows, as may be agreed upon between the subdivider and the Village. The excess cost may be recouped via right of recovery form the respective development(s).

§ 74-8.10 Stormwater management facilities.

[2-28-2022 by Ord. No. 08-2022]

The subdivider shall construct stormwater management facilities, which may include curbs and gutters, catch basins and inlets, storm sewers, road ditches, open channels, infiltration facilities, storage facilities, and settling basins, including bioretention basins with underdrains, infiltration trenches, and other green stormwater infrastructure as may be required. All such facilities are to be of adequate size and grade to hydraulically accommodate potential volumes of flow. The type of facilities required and the design criteria shall be determined by the Public Works Director while considering the nature of the topography and discharge location within and adjacent to the land division. Stormwater management facilities shall be so designed as to prevent and control soil erosion and sedimentation and present no hazard to life or property. The size, type, and installation of all stormwater management facilities proposed to be constructed shall be in accordance with the plans and specifications approved by the Public Works Director.

The subdivider shall assume the costs entailed in constructing stormwater conveyances, infiltration facilities, and storage facilities necessary to serve the proposed development, to achieve the intended level of control of nonpoint source pollution, and to carry the existing stormwater flows through the proposed development. If larger conveyance, infiltration, and storage facilities are required to accommodate flows originating from outside the proposed development, or to avoid flooding attendant to increased flows downstream of the proposed development caused not by the development but by preexisting development upstream, the cost of such facilities shall be prorated in proportion to the contributing rates of flows, and may be recouped via right of recovery from the respective future development(s).

§ 74-8.11 Water supply facilities.

[2-28-2022 by Ord. No. 08-2022]

The subdivider shall construct water mains in such a manner as to make adequate water service available to each lot or unit within the land division or condominium. If municipal water service is not available, the subdivider shall make provision for adequate private water systems as specified by the Village, county, and state agencies concerned. The Plan Commission may require the installation of water laterals to the street lot line. The size, type, and installation of all public water mains proposed to be constructed shall be in accordance with plans and specifications approved by the Public Works Director and the Racine Water Utility.

The subdivider shall assume the cost of installing all water mains eight inches in diameter or less in size.

The subdivider may install public street lamps along the entire public roadway. The Plan Commission shall approve the design and location of all street lamps, which shall be compatible with the neighborhood and type of development proposed. Shielded luminaries with downward reflection, luminaries with cutoff optics, LED or similar energy-saving luminaries, and careful fixture placement may be required by the Plan Commission.

In lieu of or in addition to the installation of public street lamps, the Plan Commission may permit the installation of private post lamps on each lot of a land division and at appropriate locations within a condominium. The type and location of such post lamps shall be approved by the Public Works Director and shall be maintained by the homeowners' or condominium association. These lamps shall not replace the requirement for public street lamps at intersections per § 74-8.13(a).

§ 74-8.14 Street and traffic control signs and signals.

[2-28-2022 by Ord. No. 08-2022]
