Such action shall not be taken unless the proprietor has delivered the materials listed above and paid the applicable fees to the Township Treasurer.
Preliminary plat tentative approval. Following pre-preliminary tentative approval by the Planning Commission, the proprietor shall make a preliminary plat and submit 15 copies to authorities as provided in Sections 111 to 119 of the Land Division Act of 1967, as amended. The preliminary plat should indicate all detailed schematic plans for proposed roads and all proposed utilities. The proprietor shall also submit materials required by Chapter 282, a detailed tree survey and replacement plan, and Chapter 275, wetland mitigation plans. The Planning Commission shall not give tentative approval until it has received necessary permits from the Michigan Department of Environmental Quality and United States Corps of Engineers. The tentative preliminary plat shall be reviewed by the Planning Commission for a recommendation to the Township Board. The Township Board of Trustees shall not give tentative approval to a preliminary plat until it has been reviewed by the Planning Commission after public hearing and its recommendations received. Tentative approval under this section shall confer upon the proprietor, for a period of one year from approval date, the rights granted under Section 112 of the Land Division Act, including approval of lot sizes, lot orientation and street layout.
Preliminary plat final approval.
Following the receipt of all necessary permits from the Wayne County Department of Public Service, or any other applicable agencies, the preliminary plat shall be reviewed by the Planning Commission for a recommendation to the Township Board. Any changes to the preliminary plat required by Wayne County Department of Public Service shall be subject to approval by the Planning Commission.

The arrangement of streets shall provide for the continuation of existing streets from adjoining areas into new subdivisions, unless otherwise approved by the Township Board, following a recommendation by the Planning Commission, due to documented environmentally sensitive features, unusual lot configuration or unique site conditions. Where adjoining vacant areas are zoned or planned for development similar to the proposed subdivision, streets shall be extended to the boundary line of the tract to make provision for the future street connections. The proprietor shall demonstrate that the proposed stub street is in a reasonable location for extension into the adjacent lands, in consideration of such factors as grades, water bodies, wetlands and lot configuration.
Streets shall be aligned to maximize the preservation of natural features and existing grades to the extent feasible. Streets should follow natural topography to minimize grading.
The proposed subdivision street layout shall discourage use by through traffic, except where a continuation of streets to adjoining properties is deemed desirable by the Township.

Blocks. Blocks within subdivisions shall conform to the following standards:
Length of blocks between intersecting streets shall be no less than 500 or more than 1,320 feet in length.
A block shall be so designed as to provide two tiers of lots and shall not be less than 240 feet, except where lots back into a major thoroughfare, natural feature or subdivision boundary.
Lots. Lots within subdivisions shall conform to the following standards:
Lot areas and widths shall conform to at least the minimum requirements of Chapter 285, Zoning, for the district in which the subdivision is proposed, provided each residential lot platted shall contain an area of at least 20,000 square feet and a width of not less than 100 feet.
The lot size, width, depth and shape in any subdivision proposed for residential uses shall be appropriate for the location and the type of development contemplated.
Narrow deep lots shall be avoided. The depth of a lot generally shall not exceed four times the width as measured at the building line.
Side lot lines shall generally be at right angles or radial to the street center lines. This requirement shall not apply where such lot lines would create irregularly shaped lots which would unreasonably limit construction, or where adjustments to the standard lot configuration would protect regulated wetlands or preserve other natural features, such as topography. Lot lines shall generally be straight and not include jogs that create irregularly shaped lots (dogleg lot lines).
Lots shall have a front-to-front relationship across all streets.
Blocks shall be so designed as to provide two tiers of back-to-back lots, except where lots back onto a major thoroughfare, natural feature or subdivision boundary.
Through lots (lots with frontage on two parallel streets) are prohibited, except in the case of a reverse frontage lot that abuts a major thoroughfare where access to such major thoroughfare is prohibited.
Corner lots shall be platted at least 10 feet wider than the minimum width permitted by Chapter 285, Zoning.
Lots facing a three-way intersection should be aligned to prevent oncoming headlight glare into the living area of the building envelope.

Areas of the subdivision plat that contain ponds, rivers, canals, or similar bodies of water shall be recorded as acreage, but shall not be platted as subdivision lots nor calculated as a portion of the minimum lot area as required by Chapter 285, Zoning. This provision shall not apply to artificial ponds or pools created on a lot after final plat approval.
Lands subject to flooding or otherwise deemed by the Planning Commission to be uninhabitable shall not be platted for residential purposes, or for uses that may in the judgment of the Planning Commission increase the danger to health, life, or property, or increase the flood hazard. Such land within a subdivision shall be set aside for other uses, such as parks or other open space.
Lots that back into such features as arterial streets, shopping centers, or industrial properties shall contain a landscaped easement along the rear at least 30 feet wide in addition to the utility easement to restrict access to the arterial street to minimize noise and to protect outdoor living areas. Lots extending through a block and having frontage on two local streets shall be prohibited.
Sidewalks, pedestrian through-block connectors and bike paths.
Sidewalks or bike paths may be required by the Township Board, based upon a recommendation by the Planning Commission, on both sides of the street or road.
Pedestrian through-block connectors may be required in the middle of any block over 1,320 feet in length to obtain satisfactory pedestrian circulation within the subdivision, to provide access to parks or open space, to provide links with an adjacent subdivision, or to provide access to an activity center. Where such pedestrian through-block connectors are required, an area at least 20 feet wide shall be provided between lots. The Township may require placement of a fence along the easement to ensure the location is visible and to protect the adjacent property owners. Pedestrian through-block connectors shall be paved in accordance with the specifications of the Township Engineer, provided gravel paths or wooden boardwalks may be permitted in areas with sensitive environmental features.
The Township Board, based upon a recommendation of the Planning Commission, may require a bike path be provided from a subdivision where it abuts a major thoroughfare. The Township may also require a bike path to provide access from within the subdivision to existing or proposed bike paths outside the subdivision, or to schools, parks, commercial areas and public institutions.
All sidewalks shall be a minimum five feet wide and constructed to the specifications of the American Association of State Highway and Transportation Officials (AASHTO).
Bikepaths shall be at least eight feet wide and constructed in accordance with the specifications of AASHTO.
Sidewalks and bike paths shall be installed by the developer within the dedicated street right-of-way, private road access easements or special easement where grades or other factors prevent placement within the right-of-way or access easement.
Landscaping. The selection, size, spacing and planting of all landscaping within a subdivision shall comply with the landscaping standards of Chapter 285, Zoning, and the following standards:
Tree species should be selected for tolerance of the harsh roadside conditions in southeast Michigan, for compliance with sight distance requirements, to ensure maintenance of accessibility to fire hydrants, to provide a minimum overhead clearance of 15 feet over any roadway and eight feet over a sidewalk or bike path, and to avoid interference with overhead or underground utility lines.
Plantings within 15 feet of a fire hydrant shall be no taller than six inches.
The development and planting of required landscaping shall be the responsibility of the proprietor, not the individual lot owner.
The Township Board, upon recommendation from the Planning Commission, may approve fewer trees if the proprietor provides evidence that existing healthy trees over 2.5 inches in diameter at breast height (dbh) or natural habitat areas will be preserved during and after construction.
The landscape plan shall be approved by the Township Board, upon recommendation of the Planning Commission, as part of the final preliminary plat process in consideration of the above and compatibility with the visual character of the surrounding area.
The minimum size of all street trees shall be three-inch caliper.
One canopy tree shall be planted for each 50 linear feet along a median boulevard.
Street trees shall be planted so that each lot has at least two canopy trees and each corner lot has at least three canopy trees. Street trees shall be placed to avoid any future driveway locations.
Street trees shall be at least 50 feet from the intersection of two street right-of-way lines or access easements.
Street trees shall be planted between the curb and sidewalk. Where tree location in the public right-of-way is not possible due to conflicts with overhead or underground utility lines or restrictions of the WCDPS, street trees may be located on private property just beyond the front lot line, subject to Planning Commission approval. Where a meandering sidewalk or bike path exists or is approved, the street tree locations shall be determined by the Township. Trees shall be at least four feet from the edge of any paved surface and shall not interfere with sight distance required by the WCDPS.
The lowest branch of any canopy tree shall provide a minimum fifteen-foot clearance over a public street or private road, and a minimum eight feet above grade from a sidewalk or bike path. Greater clearances shall be provided if required by the WCDPS.
Landscaping in culs-de-sac.
A minimum of one canopy tree for every 1,000 square feet of ground area, rounded upward, shall be planted within each cul-de-sac or island (e.g., if the island is 2,305 square feet, three canopy trees would be required).
The lowest branch of any canopy tree within the island shall be a minimum eight feet above the grade of the island and 15 feet above the grade of the roadway.
The island must either be mounded to a height of between one foot six inches and two feet six inches and planted with grass or ground cover or have four low shrubs planted for every 1,000 square feet of ground area. The shrubs shall be maintained at a maximum height of two feet six inches.
Subdivision entrances. Subdivision entrances may include landscaping, lighting, identification signs, wrought iron fences or other architectural features. All such features shall comply with Chapter 285, Zoning. A detail of the entranceway shall be submitted with the tentative preliminary plat. Signs shall not be lit. Any features proposed to be placed within the county road right-of-way must meet WCDPS design and sight distance standards. Any features proposed to be placed outside of the county road right-of-way must be located within an easement recorded for the maintenance of such features by the subdivision association.
Landscaping as a buffer zone or transition zone. The Township Board, upon recommendation by the Planning Commission, may require landscaping along the periphery of the subdivision to serve as a buffer zone from adjacent uses. A buffer zone may include trees, shrubs, berms or a combination. A buffer zone may include preservation of existing woodlands or slopes, or the addition of landscaping to provide an effective screen. Such buffer zone may be located within lot setback areas, provided a landscape conservation easement shall be recorded over such buffer zone.
Required landscape greenbelt. When a subdivision borders a major thoroughfare, and wherever a rear yard abuts a public street or private road, an easement or outlot for construction of a thirty-foot-wide landscape greenbelt shall be provided, in addition to the required rear yard setback, measured from the interior setback line. This buffer zone shall be planted with a minimum of one canopy tree and one evergreen tree for each 20 feet of greenbelt length. Existing natural features shall be retained wherever possible to promote a natural appearance and to protect the existing ecosystem within the greenbelt. Where a freeform berm is used as part of the landscape greenbelt, the minimum height shall be two feet six inches. The maximum slope of the berm facing the primary road shall be 6:1 and the maximum slope of the berm facing the inside of the lot shall be 3:1. The construction of the greenbelt and its plantings shall be the responsibility of the developer and not the individual lot owner(s).
Detention/retention pond. A minimum of one evergreen tree shall be planted every 40 feet around the perimeter of all detention or retention ponds. If the pond is fenced, then landscaping shall be provided at a rate of one evergreen tree shall be planted every 20 feet around the perimeter of the detention or retention pond.
Proprietors are required to install water mains, pavements, storm drains, sanitary sewers, and sidewalks in public rights-of-way, together with all structures appurtenant to each, and to do all landscaping outlined in § 238-7 in the lands described in the final plat.
All lots shall be served by the Township's public sanitary sewer system. Detailed plans for installing sanitary sewers shall be submitted to the Township Engineer for approval. Upon approval by the Township Engineer, he will forward the plans to the Michigan Department of Health for its approval and construction permit.

Such paved surfaces shall include all necessary excavation, grading, storm sewers, drainage structures, and be of such a character as to meet with the current specifications of the Roads Division of the Wayne County Department of Public Services.
When specified, concrete sidewalks shall be installed in the rights-of-way, detailed plans for which shall be approved by the Township Engineer. Sidewalks located along the frontage of lots shall be installed prior to an occupancy permit being issued for each home, or within six months of issuance of an occupancy permit where a performance bond is posted with the Township guaranteeing that the sidewalk shall be installed. Where required, the subdivision deed restrictions shall specify that sidewalks must be installed along all road frontages and the maintenance shall be the responsibility of the abutting lot owner.
All landscaping shall be installed prior to approval of the final preliminary plat, with the exception of street trees. Street trees shall be installed prior to a final occupancy permit being issued for each home, or within six months of issuance of an occupancy permit where a performance bond is posted with the Township guaranteeing that the trees shall be installed. The subdivision deed restrictions should state that occupancy permits for homes shall not be granted until the required tree is installed.
Street signs bearing the names of streets of a design approved by the Wayne County Road Commission shall be located at every street intersection.

On work inspected by the Wayne County Department of Public Services the proprietor shall pay the inspection fees required by the Commission.
If a plat shows certain proposed improvements in addition to those required by this chapter, the Land Division Act of 1967 of the State of Michigan, as amended and as required and pursuant to Chapter 98 of this Code, such as playgrounds, lakes, lagoons, slips, waterways, bays or canals which are not in existence at the time of consideration of the plat, the Township Board may, as a condition to the approval of the plat, require the proprietor to enter into an agreement with the Township to complete such improvements within a reasonable time set by the Board. The Board may also require security deposits to secure performance of such agreement in the manner and form provided in § 238-11 of this chapter.
Following final approval of the preliminary plat, the proprietor shall be required to deposit with the Clerk or an escrow agent cash, surety bond, or certified check, or the equivalent approved by the Township Board, whichever the proprietor elects, to insure construction of all improvements, except where such deposits are required by Wayne County. The amount of deposit or bond shall be set by the Township Board based on an estimate prepared by the developer's engineer and approved by the Township Engineer. The deposit or bond shall guarantee the completion of the required improvements within a period of time specified by the Township Board from the date of the approval of the final plat. The Township Board or escrow agent with approval of the Board shall rebate to the proprietor, as the work progresses, amounts of any cash deposits equal to the ratio of the work completed to the entire project.
The abstract of title, title insurance policy or attorney's opinion and other information required by Section 245 of the Land Division Act of 1967 of the State of Michigan, as amended, shall be furnished by the proprietor before final approval of the preliminary plat by the Township Board.
All plats shall conform with the Comprehensive Plan (Master Plan) of the Township in effect at the time the plat is presented for approval.
The Township Board may grant a variance from the requirements of this chapter as follows:
Process. The process for a variance request from this chapter shall be as follows:
Applications for any variance shall be made in writing to the Township Clerk by the developer prior to approval of the final preliminary plat. The application shall state fully and clearly all facts relied upon by the proprietor. The application shall include any required fee, and be supplemented with maps, plans, and other additional data which may aid the Planning Commission in the analysis of the requested variance.
The request shall be forwarded to the Planning Commission. The Planning Commission shall first conduct a public hearing. Notice of the public hearing shall be posted in a newspaper of daily record and sent to landowners within 300 feet of the parcels or lots for which the variance is sought.
Following the public hearing, the Planning Commission shall provide a recommendation to the Township Board, in accordance with the standards below.
The Township Board shall make a decision on the request. In making its decision, the Township Board may establish requirements, time constraints or conditions that will, in its judgment, secure substantially the objectives and requirements of this chapter. The Township Board shall state the reasons for its finding or decisions as part of its official records.
The Township Board shall have the final authority on variances, waivers or modifications of the standards of this chapter, except Wayne County must also approve any variances from county standards. Appeals of the Township Board decisions shall be to a court of law.
Variance standards. The decision on a variance request shall be based on a finding that practical difficulties result from strict compliance with specific provisions or requirements of the chapter. In making its finding, the Township Board shall take into account the nature of the proposed use of land and the existing use of land in the vicinity, the number of persons to reside or work in the proposed subdivision, and the probable effect of the proposed subdivision upon traffic conditions in the vicinity. No variance or waiver shall be recommended unless the Township Board finds that:
There are special circumstances or conditions affecting said property such that the strict application of the provisions of this chapter would deprive the applicant of the reasonable use of his land.
The variance is necessary for the preservation and enjoyment of a substantial property right of the petitioner.
The granting of the variance will not be detrimental to the public welfare or injurious to other property in the territory in which said property is situated.
The variance or waiver will not have the effect of nullifying the intent and purpose of this chapter and the Township Master Plan.
Variances from Chapter 285, Zoning. Variances or waivers from requirements of Chapter 285, Zoning, may be considered by the Zoning Board of Appeals where, in the case of a particular proposed subdivision, it can be shown that strict compliance with the requirements of this chapter would result in extraordinary hardship to the proprietor because of unusual topography or other physical conditions which are not self-initiated or that these conditions would result in inhibiting the achievement of the objectives of this chapter, a variance may be granted. Such variances shall be reviewed in accordance with the procedures and standards contained in Chapter 285, Zoning.
With the filing of each application, a nonrefundable application fee shall be paid to the Township, in an amount specified by resolution of the Township Board, to cover Township administration, review and inspection costs related to the subdivision.
