  • Shoreland zoning ordinance applies within the shoreland zone; land-use ordinance district and dimensional rules apply elsewhere in the town.
  • The town's 2026 Land Use Ordinance revision PDF returned no extractable text, so its adopted content was not read.

  “by enforcing the shoreland zoning and land use codes, which have been developed and adopted by the community over the years”

• Minimum lot sizeDistrict specific (with conditions)

  Lots inside Portage Lake town limits, by land-use district (growth, rural, industrial, cluster development), per the 2026 dimensional requirements table

  • The table's text extraction is garbled, so the district-to-number mapping was not confirmed; per-district figures were not recorded as parameters.
  • The table notes industrial lot size is as determined by the Portage Lake Planning Board.
