(A) Base density. To compute the base density, the buildable area within each tier, as calculated in § 150.235(E), is divided by the single residential lot size standard for the zoning district. This shall yield a base density of dwelling units or sites for each tier.
(B) Transferability. Allowable base densities may be transferred from any tier to any other tier further from the shoreland water body or watercourse, but must not be transferred to any other tier closer.
(C) Density increases. The city shall allow some dwelling unit or site density increases for residential planned unit developments as provided for in the following.
(1) When density increases are allowed, they shall be allowed only in conformance with the following table.
Criteria
|
Density Increase, Tier 1
|
Density Increase, Tier 2
|
Density Increase, Tier 3 and Beyond
|
Criteria

Density Increase, Tier 1

Density Increase, Tier 2

Density Increase, Tier 3 and Beyond
|
Connection to city sewer | 20% | 40% | 50% |
External vegetative buffer increased to an average of 75 feet | 5% | 20% | 25% |
External vegetative buffer increased to an average of 100 feet | 10% | 40% (not cumulative) | 50% (not cumulative) |
Maintain 100-year, 24-hour storm event onsite | 10% | 20% | 25% |
Open space increased to 40% of total area | 5% | 20% | 25% |
Restore and maintain shoreland in its original/natural state | 10% | 20% | 20% |
Screening increased to 75% effective | 5% | 20% | 25% |
Screening increased to 100% effective | 10% | 40% (not cumulative) | 50% (not cumulative) |
Setback from lake increased 50% | 5% | 10% | 10% |
Setback from lake increased 100% | 10% | 20% (not cumulative) | 20% (not cumulative) |
Notes to table: Increases are from the base density. Stepped increases do not result in cumulative density increases (e.g., a 75-foot buffer allows a 5% increase in Tier 1. A 100-foot buffer would allow an additional 10% increase in Tier 1 for a total of 15% as shown in the table). | |||
(2) Increases in unit or site densities shall not exceed the following maximums.
Tier
|
Maximum Density Increase
|
First | 50% |
Second | 100% |
Third and each subsequent tier | 200% |
(D) Administration and any maintenance requirements. Prior to final approval of any residential planned unit developments, the city will require adequate provisions developed for preservation and maintenance in perpetuity of open spaces and for the continued existence and functioning of the development as a community.
(1) Membership must be mandatory for each dwelling unit or site purchaser and any successive purchasers.
(2) Each member must pay a pro rata share of the association’s expenses, and unpaid assessments can become liens on units or sites.
(3) Assessments must be adjustable to accommodate changing conditions.
(4) The association must be responsible for insurance, taxes, and maintenance of all commonly owned property and facilities.
(5) Changes to owner’s association must be approved by the city.
