B.
Uses Permitted. Information on permitted uses, development standards and regulatory requirements are found in the town SMP.
C.
Lot Size, Allowable Densities, Lot Coverage, Height and Setbacks. Lot sizes, allowable densities, lot coverage, height and setback requirements in the shoreline overlay shall be as set forth in underlying zoning district, except where the requirements of the town SMP are more restrictive.

Development within areas covered by the shoreline overlay shall be subject to standards and requirements of the town shoreline master program (SMP). Whenever a conflict arises between the standards and regulations contained within the SMP and this title, the more restrictive provisions shall apply.
B.
Standards. The following development standards shall be mandatory for all development and uses in areas covered by the conservancy overlay:
1.
Approved landscape plans shall be implemented as soon as weather allows after completion of construction, which will provide plantings which, either separately or combined with wood fencing or earthen berms, provide visual screening of parking areas, trash areas and other service areas of the development, and break up the visual impact of the development from public roads and neighboring properties, and which will eliminate and prevent the occurrence of noxious weeds. Landscaping must be maintained to assure viability of plantings; underground or other timed outdoor water systems may be required by the administrator for water conservation.
2.
Storm water shall be channeled and disposed of by dispersal through a grassy area of sufficient size for the anticipated amount of storm water runoff, or by release into a properly designed dump area with filtration system or devises installed (including oil/water separator if called for by the size of development and the amount of traffic to be generated thereby, and by the size of the paved areas and other impervious surfaces) or other acceptable method to assure no degradation of the surface or ground waters.
3.
Dust control measures shall be implemented to provide assurance of continual dust control during construction and upon occupation of the development. All roads and parking areas shall be paved or similarly surfaced to provide long-term dust control.
4.
Dog control measures shall be mandatory within the conservancy overlay.
5.
Compliance with the provisions and procedures of the State Environmental Policy Act and local regulations thereunder shall precede any applicable development.
C.
Review and Approval. The administrator shall review the measures proposed for compliance with these development standards and shall approve or conditionally approve a building permit application to assure compliance with these standards.
D.
The storage, treatment, processing and manufacture of hazardous materials and/or waste shall be prohibited in shoreline and conservancy overlays.
E.
Construction on slopes exceeding fifteen (15) percent shall require detailed plans and specifications and be designed to minimize adverse impacts to the environment.
