§ 70-5. Community impact statement.  


Latest version.
  • The following information is required for community impact statements:
    A. 
    Existing site conditions. Illustrations and a narrative shall be provided that describe the characteristics of the site and adjacent right-of-way. This description should include surrounding land uses, expected development in the vicinity which could influence future utility capacity, special site features and a description of any committed infrastructure improvements.
    B. 
    Proposed development. The applicant shall prepare a description of the proposed development with an enumeration of the square footage for nonresidential and number of each unit-type for residential development. Residential equivalent unit figures shall be provided for water for the new development. The proposed utility system to be constructed as part of the development shall be detailed on the site plan or subdivision plat.
    C. 
    Wastewater systems. The study shall demonstrate that the proposed development will be served by adequate public sanitary sewerage. The public sewerage system shall be considered adequate if there is sufficient unreserved or uncommitted available capacity to accommodate expected and ultimate peak flows from the proposed development, and any necessary improvements shall be constructed and on-line prior to completion of the development. The analysis of the capacity of the public sewerage system shall consider the following:
    (1) 
    The sewer system's design capacity.
    (2) 
    The sewer system's available capacity.
    (3) 
    The projected wastewater flow to be generated by proposed new development.
    (4) 
    The impact of other proposed projects on the sewer system's available capacity.
    (5) 
    Projects appearing in the Township's Capital Improvements Program that will affect the ability of the sewer system to serve new development.
    (6) 
    Other variables found to have an effect on the ability of the sewer system to accept the projected wastewater flow from new development.
    (7) 
    The sewer system shall be adequate to serve the development. All lots shall tie into an appropriately sized collector main and shall not tie directly into an interceptor.
    D. 
    Water systems. The study shall demonstrate that the proposed development will be served by adequate public water. The public water system shall be considered adequate if the source facilities, storage tanks, pumping stations and distribution systems have sufficient unreserved or uncommitted capacity available to provide the pressure and flow required in addition to minimum fire suppression flow for the proposed development, and any necessary improvements shall be constructed and on-line prior to completion of the development. The analysis of the capacity of the public sewage system shall consider the following:
    (1) 
    The water system's design capacity.
    (2) 
    The water system's supply source.
    (3) 
    The water system's available capacity.
    (4) 
    The projected water needs of proposed new development to include needs for domestic consumption and fire protection.
    (5) 
    Adequacy of the proposed system design to provide pressure, flow and fire suppression, including required looping of water mains.
    (6) 
    Existing storage, treatment, and pumping facilities affected by the proposed development.
    (7) 
    The impact of other proposed projects on the water system's available capacity.
    (8) 
    Projects appearing in the Township's Capital Improvements Program that will affect the ability of the water system to serve new development.
    (9) 
    Other variables found to have an effect on the ability of the water system to satisfy the projected water needs of the new development.
    E. 
    Stormwater Management. The study shall demonstrate that the proposed development will provide adequate stormwater management in accordance with Chapter 233, Stormwater Management. The stormwater management plan shall be considered adequate if the development is designed, constructed, and maintained to control runoff, prevent flooding and protect water quality. The analysis of the stormwater management shall consider the following:
    (1) 
    Prevention of increased runoff, flood hazards, water pollution related to stormwater runoff, soil erosion, channel erosion and impact to downstream properties.
    (2) 
    Prevention of impact to wetlands, watercourses or fish and wildlife habitat.
    (3) 
    Stormwater best management practices to decrease runoff velocity, allow for natural infiltration and passive storage, allow suspended sediment particles to settle, and to remove pollutants.
    (4) 
    Controlled release of stormwater in accordance with the Wayne County design standards and Chapter 233, Stormwater Management.
    (5) 
    Stormwater facilities near the Grosse Ile Airport shall not create an increased bird-aircraft strike hazard.
    F. 
    Other utilities. Information shall be provided regarding other utilities that will be provided to the site, including electricity, gas and telecommunications. Documentation shall be provided that there is sufficient electrical capacity to serve the development without impacting existing uses during peak demand periods.
    G. 
    Schools. The study shall demonstrate that there is adequate school capacity to support the number of dwelling units and that the capacity of public schools will not be adversely affected by residential development. School capacity will consider current and projected enrollments, capacities of individual schools and capacity at each grade level.
    H. 
    Recreation. For any residential development, the study shall demonstrate that there is adequate open space and recreation facilities to serve the number of dwelling units proposed. All residential developments shall include neighborhood open space as required by Chapter 238, Subdivision Control.
    I. 
    Community character. The study shall demonstrate compatibility with surrounding land uses and adherence to development standards, including landscaping requirements, in accordance with Chapter 285, Zoning. The study shall also demonstrate consistency with the sustainable island character of the Township, as articulated in the Township Master Plan.
    J. 
    Environment. The study shall demonstrate that the proposed development will minimize impact to the environmental conditions of the Township, through incorporation of an environmental assessment prepared in accordance with Chapter 98, Environmental Assessment.
    K. 
    Township standards. All utilities shall be designed to meet the requirements of Chapter 210, Sewer Use, Chapter 238, Subdivision Control, Chapter 258, Utilities, and other applicable Township engineering standards. Utilities shall be designed and installed with proper access for maintenance by the Township.
    L. 
    Phased developments. Where a development is to be constructed in phases, a phasing plan shall be provided that indicates the improvements to be completed with each phase. Each phase of a development shall have all necessary infrastructure installed to fully operate independently in accordance with the Township engineering requirements, regardless of whether future phases are constructed.
