Purpose. Planned Development Districts comprise individual special districts, which, over time, promote the maximum benefit from coordinated area site planning and diversified location of structures and which may have mixed compatible uses.

Limitations on use. No property owner may apply for a PDD unless the proposed development is impossible under otherwise applicable zoning regulations. Approved PDDs may only alter standards within this zoning chapter and City street cross-sections. No PDD may alter any other City-adopted standard.

Review procedure. The City shall review PDD districts and proposed amendments to approved districts per § 15.07. In reporting the application to the Plan Commission and Common Council, the Zoning Administrator must also describe why the PDD is preferable to amending the standard zoning ordinances.

Application materials. Applicants must submit the following application materials.

Phasing. The City may approve a phased development plan within a PDD if the applicant details each phase within the proposed development plans.

Lapse of approval. All PDDs shall automatically lapse and revert to the property's previous zoning district unless the property owner applies for a building permit for the subject property within 12 months of approval.

Abandonment. The City may abandon any existing PDD per § 15.07.

District boundaries. The Shoreland-Wetland Zoning District includes all wetlands in the municipality which are 3.5 acres or more and shown on the final Wetland Inventory Map that has been adopted and made a part of this chapter and which are:

Determinations of navigability. The Zoning Administrator shall make determinations of navigability and ordinary high-water mark locations. When questions arise, the Zoning Administrator shall contact the appropriate district office of the Department for a final determination of navigability or ordinary high-water mark.

Apparent discrepancies. When an apparent discrepancy exists between the Shoreland-Wetland District boundary shown on the official zoning maps and actual field conditions at the time the maps were adopted, the Zoning Administrator shall contact the appropriate district office of the Department to determine if the shoreland-wetland district boundary as mapped is in error. If Department staff concur with the Zoning Administrator that a particular area was incorrectly mapped as a wetland, the Zoning Administrator shall have the authority to immediately grant or deny a zoning permit in accordance with the regulations applicable to the correct zoning district. In order to correct wetland mapping errors or acknowledge exempted wetlands, the Zoning Administrator shall be responsible for initiating a map amendment within a reasonable period.

Filled wetlands. Wetlands which are filled prior to April 15, 1989, the date on which the municipality received final wetland inventory maps, in a manner which affects their wetland characteristics to the extent that the area can no longer be defined as wetland, are not subject to this chapter.

Wetlands landward of a bulkhead line. Wetlands located between the original ordinary high water mark and a bulkhead line established prior to May 7, 1982, under § 30.11, Wis. Stats., are not subject to this chapter.

Artificial areas. Per § 61.353, Wis. Stats., the shoreland protection regulations of this division do not apply to lands adjacent to an artificially constructed drainage ditch, pond, or retention basin not hydrologically connected to a natural navigable water body.

Setbacks. The City establishes a shoreland setback area of at least 50 feet from the ordinary high-water mark; except a property owner may construct or place a principal building within the shoreland setback area if all of the following apply:

Purpose. The Environmental Corridor Overlay preserves environmental corridors to recharge and discharge groundwater; maintain surface water and groundwater quality; reduce flood flows and flood stages; maintain base flows of streams and watercourses; reduce soil erosion; abate air and noise pollution; provide wildlife habitat; protect plant and animal diversity; protect rare and endangered species; maintain scenic beauty; provide opportunities for recreational, educational, and scientific pursuits; and avoid serious and costly development problems because these areas are frequently poorly suited for urban development.

District boundaries. The Environmental Corridor Protection Overlay includes the most up-to-date delineation of all primary and secondary environmental corridors and isolated natural resource areas delineated by the Southeastern Wisconsin Regional Planning Commission.

Permitted uses. The City permits only necessary transportation and utility uses, O-2 uses, and R-1 uses within the zone.

Zone coverage. The City limits development, as measured by impervious coverage, within the zone to no more than 10% of the total contiguous zoned area. Shoreland-Wetland Overlay Zones and Floodplain Zones may further restrict development areas.

Accessory building height limitations. No property owner may build an accessory building taller than the primary structure, 24 feet, or the accessory building height ratio contained within Table II-3: Height Regulations, whichever is less.

Contextual building heights. If a primary structure exists on any immediately adjacent parcel, not including parcels separated by a public right-of-way, the maximum building height shall not exceed the following multipliers.

Height. The City measures height as the vertical distance from the average ground elevation along the structure's base to the highest point of the subject structure. The average ground elevation is the midpoint between the highest and lowest ground elevations along the exterior building wall.
