A. 
Normal density, 91% open space.
(1) 
All existing parcels less than 70 acres as of October 13, 1997, shall have no more than one residential building site. If such existing parcels already possess a residence, no additional residential building sites shall be granted.
(2) 
All parcels 70 acres or more shall have the number of building sites determined as follows: the number of acres is divided by 35 and the resulting number is rounded down to the next whole number. That resulting whole number is the number of permitted building sites. (Examples: 69.9 acres divided by 35 equals 1.997, rounded down gives one building site; 70 acres divided by 35 equals 2.00, rounded down gives two building sites; 104 acres divided by 35 equals 2.97, rounded down gives two building sites.)
B. 
All parcels within the Village of New Glarus ETZ Map, Zone A-T, may not be subject to the density requirements of Subsection A above or Subsection C below but must meet the Town plat requirements for public sanitary and public services and must meet the requirements of § 110-32.
C. 
Commercial or industrial development as allowed in areas of normal density does consume a building site and may not occur in open space.
D. 
Cluster density, 85% open space. Notwithstanding Subsection A above, if cluster development is used under the guidelines of the Amended Town of New Glarus Land Use Plan, dated August 20, 1999, then the number of building sites is determined using the following criteria:
(1) 
The minimum number of lots required to qualify as a cluster is three.
(2) 
The cluster development design and layout shall meet the definition of "cluster."
(3) 
Eighty-five percent or greater of the existing parcel shall remain open space.
(4) 
Open space shall be protected from development until at least December 31, 2025, through deed restrictions or affidavits.
[Amended 12-9-2020]
(5) 
Open space that is commonly owned by the cluster development shall be managed in a stewardship-like manner to permit active and passive recreational use of the commonly owned open space by residents of the development and be compatible with adjoining land.
(6) 
Open space that continues to be utilized for agricultural purposes shall be utilized in a manner compatible with adjoining restrictions.
(7) 
Fifteen percent or less of the existing parcel may be classified residential and eligible for building permits, if all other code requirements are met.
(8) 
Minimum lot size shall be two acres.
(9) 
Examples.
(a) 
Example No. 1. A forty-acre existing parcel under cluster development would be permitted three building sites (40 acres times 15% divided by two acres equals three). If there is an existing residence, the other two building sites would have to be clustered around the existing residence. If there is no existing residence, the three building sites could be located elsewhere. Any existing parcel less than 40 acres would not be able to take advantage of cluster development.
(b) 
Example No. 2. An existing parcel of 53.34 acres under cluster development would be permitted four building sites (53.34 acres times 15% divided by two acres equals four). If there is an existing residence, the other three building sites could either be clustered around the existing residence or clustered elsewhere.
(c) 
Example No. 3. An eighty-acre existing parcel under cluster development would be permitted six building sites (80 acres times 15% divided by two acres equals six). The developer could have up to two clusters with at least three building sites in each cluster. If there is an existing building site, that site could be unclustered and the other five would then have to be clustered in one location.
(10) 
Only single-family detached dwellings can be included in a cluster development.
