Cued up for the Bloomington city council’s consideration next Tuesday are 20 more amendments to the draft update to the unified development ordinance, which is the city’s basic zoning and development document.

They include an amendment sponsored by councilmember Chris Sturbaum for reduction in height limits from 40 to 35 feet in single-family residential neighborhoods. A separate amendment swaps in a better diagram to illustrate how height is measured for buildings, taking into account the highest point and the grade surface.

Another amendment sponsored by Sturbaum would change four-plexes, multifamily dwellings and live/work dwellings in a residential multifamily (RM) district from permitted uses to a conditional uses.

Also in the mix is an amendment sponsored by councilmember Steve Volan that reduces the maximum amount of on-site parking that can be provided by a new development for several specific uses. For example, for a student housing or dormitory use, a reduction is proposed from a maximum of 0.75 to 0.25 spaces per bedroom.

Among the 20 amendments on the council’s docket for next Tuesday are some that cover somewhat less familiar subject matter. For example, councilmember Isabel Piedmont-Smith is sponsoring an amendment to clarify how to measure the buffer area around a compound sinkhole.

In recent weeks, over the course of four sessions that have been dedicated just to amendments of the UDO, the city council has already dispatched with amendments numbered 1 to 39. A couple were withdrawn without consideration.

Several, even most, of the 20 amendments for Dec. 3 could wind up on a consent agenda, which would be moved and voted on all in one step. It’s a technique the council used its Nov. 19 meeting on UDO amendments.

The Dec. 3 meeting date was added to the council’s calendar by a council vote at its Nov. 20 meeting. At its regular session on Dec. 4, the council will likely clarify the remaining schedule for UDO amendments, based on how much progress is made the night before. Several additional technical amendments, which had a submission deadline of Nov. 25 are still expected to be proposed.

Already on the council’s schedule are meetings for Dec. 10, Dec. 12 and Dec. 17, with a final vote on the amended UDO possible on Dec. 18.

Height in R2

Sturbaum’s Amendment 40 would reduce height limits from 40 to 35 feet in single-family residential neighborhoods. In the documentation for his amendment, Sturbaum says that almost all buildings in the R2 zone are houses that are at most two stories tall. The proposed 40-foot limit would allow for three-story houses, according to the amendment’s annotation, or even short four-story buildings.

Such buildings would “radically change the quality and character” of their neighborhoods, according to the amendment.

Conditional use for multi-unit buildings

Sturbaum’s Amendment 42 would require four-plexes, multifamily dwellings and live/work dwellings in residential multi-family districts to undergo a conditional use public review process instead of allowing them by-right.

The amendment zeroes in on the difference between residential multi-family and high-density multi-family zoning districts.

The synopsis for the amendment given by Sturbaum says that residential family zones still contains many single-family homes and single family forms that have become multifamily. The synopsis states that:

The higher density forms that are fine in Residential HighDensity Multifamily (RH) could have negative consequences in the RM zones. Conditional use still allows their use but the application will have a chance of being more context sensitive with a public process that the conditional use provides.

Parking maximums

Probably the least controversial aspect of Steve Volan’s proposed Amendment 45 is the idea of replacing the word “requirement” with “allowance” or “limit” in places where the word is supposed to convey that it denotes a maximum amount of parking allowed.

In the table of parking maximums for various uses, several are proposed to be reduced. One example is that for a student housing or dormitory use, a reduction is proposed, from a maximum of 0.75 to 0.25 spaces per bedroom. Another example is a proposed reduction for duplexes, triplexes and four-plexes from two to one space per dwelling unit. (A duplex could have a maximum of two spaces instead of four spaces.)

In several places, the proposed maximum is not defined with a specific numerical value, but rather by means of a “default allowance.” Default allowances are defined in terms of bedrooms for residential uses and in terms of gross floor area for non-residential uses.

The default allowances are defined in a way that ratchets them incrementally downward in the two decades between 2020 to 2040. In 2020, the default allowance for residential parking uses would be 0.50 spaces per bedroom. By 2040 and after, the default residential parking allowance would fall to 0.30 spaces per bedroom.

For non-residential uses, the default parking allowance would fall from 2.00 spaces per 1,000 sq. ft. GFA in 2020 to 1.40 spaces per 1,000 sq. ft. GFA in 2040 and after.

Amendments on the Dec. 3 agenda
