§ 470-24.06 Standards for approval.

[Amended 9-12-2016 by Ord. No. 2016-13; 8-12-2019 by Ord. No. 2019-10; 2-14-2022 by Ord. No. 2022-01]
Prior to approving a site plan, the Planning Commission shall require that the following standards and requirements be satisfied. If these standards and all other requirements of applicable Township ordinances are met, the site plan shall be approved.
General access requirements.
The Planning Commission shall have the authority to require a frontage road or rear service drive for contiguous parcels along Lake Michigan Drive (M-45) or other streets as deemed necessary. The Planning Commission shall also have the authority to limit the number of driveways for a site, to require that parking lots on contiguous parcels be connected, that driveways for contiguous parcels be shared, that opposite driveways be directly aligned and that specific turning movements be restricted or prohibited. In determining whether the above or other access control measures are necessary, the following criteria shall be considered:
The type and location of commercial uses on the site and adjacent to the site.
The location, size and design of existing and proposed parking areas.
The existing and projected traffic volume on the roadway and adjacent roadways.
Compatibility between adjacent land uses and likelihood of change or expansion.
Number of parcels involved, location of lot lines and amount of road frontage.
Topography and site distance along adjacent roadways and on the site.
Distance from intersections.
Location of driveways opposite the site.
Width of roadway and number of lanes.
Environmental limitations (steep slopes, water, or vegetation).
Sufficient building setback.
Recommendation of the Township Master Plan.
The site shall be designed to minimize or avoid conflicting and unsafe vehicle turning movements on the site and at driveways serving the site; avoid driver sight obstructions; separation of pedestrian and vehicular traffic, and arrangement of parking areas that are safe and convenient and, insofar as practicable, do not detract from the design of the proposed buildings and structures and the neighboring properties and provide for vehicle access between adjoining parcels where practicable.
All buildings or groups of buildings shall be arranged to permit necessary emergency vehicle access as requested by the Township Fire Department.
All streets and driveways shall be developed in accordance with Chapter 405, Subdivision of Land, of the Township Code, the Ottawa County Road Commission or Michigan Department of Transportation (MDOT) specifications, or developed as a private road in accordance with the requirements for private roads as contained in the chapter.
Environmental considerations.
Proposed structures shall be related harmoniously to the terrain and to the existing buildings in the vicinity that have a visual relationship to the proposed buildings. The achievement of such relationship may include the enclosure of space in conjunction with other existing buildings or other proposed buildings and the creation of focal points with respect to avenues of approach, terrain features, or other buildings.
Areas of natural drainage such as swales, wetlands, ponds, or swamps shall be protected and preserved insofar as practical in their natural state to provide areas for natural habitat, preserve drainage patterns and maintain the natural characteristics of the land.
Stormwater management: Appropriate measure shall be taken to ensure that removal of surface waters will not adversely affect neighboring properties or the public stormwater drainage system. Surface water on all paved areas shall be collected at intervals so that it will not obstruct the flow of vehicular or pedestrian traffic or create puddles in paved areas. If practical, stormwater shall be removed from all roofs, canopies, and paved areas and carried away in an underground drainage system. Temporary on-site storage to reduce peak run-off from the site is encouraged. Catch basins may be required to contain oil filters or traps to prevent contaminants from being discharged to the natural drainage system.
Sidewalks and pedestrian circulation.
Sidewalks shall be provided along those portions of the site which have frontage on a public or private street for safe pedestrian movement, and to enhance the pedestrian accessibility of the site. The sidewalks shall be designed to Ottawa County Road Commission standards. In cases where a sidewalk, or a portion of a sidewalk, is outside of the public street right-of-way, a public easement for sidewalk purposes shall be provided to the Township. Sidewalks shall be installed in conjunction with the development of the site unless arrangements are approved by the Commission to install the sidewalks at a subsequent date.
All commercial retail and service establishments shall include a pedestrian walkway adjoining the establishment's front wall and running the length of the front wall and interconnected to the pedestrian walkways(s) along the public or private roads and driveways.
All internal pedestrian walkways extending through the parking driveways and access aisles shall be continuous and constructed of dissimilar materials than that of the parking lot or driveway i.e., colored and/or stamped concrete, brick pavers, etc. All such walkways shall be a minimum of five feet wide.
In the Commercial and Office Zoning District and for such uses in a PUD zoning district a sidewalk shall be provided from the principal building to the sidewalk within any public right-of-way abutting the site. Such sidewalk shall be a minimum of eight feet wide in order to serve as a recognizable entrance point to the public. The Planning Commission may allow modifications to this requirement if, in the opinion of the Commission, such sidewalk is impractical due to the type of business, the likelihood of pedestrian use, the design of building, the distance to the public sidewalk or a practical difficulty due to natural site features.
The arrangement of public or common ways for vehicular and pedestrian circulation shall be connected to existing or planned streets and pedestrian or bicycle pathways in the area.
Landscaping and buffering.
Landscaping, landscape buffers and greenbelts shall be provided and designed in accordance with the Township's landscape provisions.[1]

Editor's Note: See also Article 21A, Landscaping Requirements, of this chapter.
The site plan shall provide reasonable visual and sound privacy for adjacent dwelling units and for dwelling units on the proposed site. Fences and walls may be required by the Planning Commission, as appropriate to accomplish these purposes. The finished side of any wall or fence shall face adjacent properties.
Lighting.
Lighting fixtures used to illuminate off-street parking areas and all other exterior lights including building lights shall be located, aimed, and shielded so as to minimize light trespassing across property boundaries and shall be so arranged as to deflect the light away from adjoining residential properties or streets and highways. Lighting fixtures in required parking facilities for commercial, industrial, or office districts within 150 feet of any residential zoning district are shall not exceed 20 feet in height. All other fixtures shall not exceed 35 feet in height. Light fixtures shall be designed to achieve total luminary cutoff.
The Planning Commission may require additional lighting for internal pedestrian walkways to avoid any dark areas.

The bump guard posts shall be spaced three feet apart. All steel bump guard posts shall be no less than six inches in diameter and completely filled with concrete.
For any enclosure containing a dumpster or other appropriate container, the minimum interior width of the enclosure and its opening shall be 10 feet and shall be clear of obstructions, including the gate, its hinges, and steel bump guard posts. In addition, at least two feet of clearance from the side walls of the enclosure shall be provided. Where enclosures contain more than one dumpster or container, the minimum interior width shall equal the combined widths of the dumpster/container plus a minimum of two feet clearance from each side. The minimum interior length for all enclosures containing a dumpster shall be at least two feet greater than the length of the dumpster or dumpsters it contains.
Any enclosure constructed prior to the adoption of this language shall only be replaced pursuant to this section, to the extent practicable as determined by the Zoning Administrator, and may not be restored or repaired in accordance with § 470-26.04.
All enclosures shall be located in the rear yard or the side yard. When located within an approved outdoor storage area, any dumpster may be absent an enclosure only if the outdoor storage area achieves the same or greater visual screening on all four sides of the dumpster and meets the provisions of § 470-24.06H(2)(d) and (e), as if an enclosure was present, and shall meet § 470-24.06H(4) through (6).

The Zoning Administrator may refer any decision regarding any proposed change to an approved site plan to the Planning Commission for review and approval, regardless of whether the change may qualify as a minor change. In making a determination whether a change is a minor change, or whether to refer a change to the Planning Commission for approval, the Zoning Administrator may consult with the Chairperson of the Planning Commission.
If the Zoning Administrator determines that the requested modification to the approved site plan is not minor, resubmission to the Planning Commission for an amendment shall be required and conducted in the same manner as an original application.

§ 470-24.11 Expansion of existing use, structure, or building.

[Amended 6-24-2024 by Ord. No. 2024-04]
It is recognized that land uses, buildings, and structures are existing which do not conform to the current regulations of this chapter and as such do not achieve the intended purposes of this chapter. When these uses, buildings, and structures are proposed to be expanded, enlarged, or increased in intensity so that a site plan review is required per § 470-24.02 herein, the Planning Commission shall require strict compliance with the current provisions of this chapter unless special circumstances exist that would preclude the site from reasonably achieving the intent and purpose of the applicable provision. In the instance the Planning Commission concludes that special circumstances exist that preclude the site from reasonably achieving the intent and purpose of a provision of this chapter, the Planning Commission may reduce the extent of compliance with each applicable provision only when it is adequately demonstrated that the nonconformity that is regulated by the applicable provision of this chapter would be reduced in nonconformity.
In determining whether to reduce the extent of compliance with any provision of this chapter, the Planning Commission shall be guided by the following criteria:
Whether compliance would ensue safer on-site conditions, protect the natural environment, improve traffic circulation, achieve compatibility with adjacent land uses, promote the use of the land in a socially and economically desirable manner and generally accomplish the purposes of site plan review as described in this section.
The practicality of requiring complete compliance with the applicable regulation of this chapter based on the existing design, layout, and operation of the existing use and size of the site.
Whether or not requiring compliance would have a negative impact on the character, safety and welfare of the neighborhood or surrounding area.
Whether the extent of the nonconformity has been reduced.
