Figure 3-2-2-1A Lot Averaging

2. Applicability. Lot averaging is required as follows:
   1. Lot averaging shall be applied to any single housing type when there are more than 20 units of the housing type in a proposed development (e.g., if there are 30 single-family detached units, 25 patio home units, and 20 standard townhome units in a development, then lot averaging must be applied to the single-family detached and patio home units, but is not required for the townhome units).
   2. Lot area groups for each housing type are provided in the tables of Division 3-2-2, Housing Palette.
   3. Where lot averaging is not required, but the tables of Division 3-2-2, Housing Palette, indicate three lot area groups, the average lot area group shall be used to establish minimum lot area and minimum lot depth for the housing type.
3. Exception. Lot averaging is not required for agricultural, equestrian, and estate lots, as described in Section 3-2-2-2, Single-Family Detached.
4. Identifying Lots in Each Group. Lots within each size group are identified by lot width, as follows:
   1. Small lots shall meet the minimum lot width for small lots, and their lot width may be up to (but not including) the lot width of the average lot category.
   2. Average lots shall meet the minimum lot width for average lots, and their lot width may be up to (but not including) the lot width of the large lot category.
   3. Large lots must meet the minimum lot width for large lots, and their width is not limited.
5. Calculating the Required Number of Lots of Each Lot Area Group. In the tables of Division 3-2-2, Housing Palette, that provide for variable lot sizes, the column titled "percent in width type," indicates the minimum proportion of each lot area group that must be provided. The minimum number of small and average lots shall be rounded up to the nearest whole number. The large lot category is always listed as "remainder" because, after the minimum proportions for small and average lots are met, the remainder of the lots may be large lots.
6. Distribution of Averaged Lots. Lots in the three lot area groups shall be distributed in at least one of the following ways:
   1. Generally, lots in each of the three lot area groups (small lots, average lots, and large lots) shall be mixed on each street segment so that they are spread through the development (except as provided in Subsection F.2., below). Concentrating lots of a single lot area group in separate areas of a development is not allowed.
   2. In the alternative, proposed development that includes a mix of housing types may designate a mix of housing types or diverse single-family detached lot sizes on a single block or street segment. Such developments are not required to strictly comply with Subsection F.1., above, if it is demonstrated that the overall distribution of housing types in the development does not unreasonably concentrate small lots.

The lot-line house is set on one property line with a zero setback, and the building is intended to be roughly L-shaped. The street side setback is the setback that is required on the street side of corner lots. The small side setback is a small side yard along the side of the building towards the front of the lot (see Table 3-2-2-5A, Note 1). The interior side setback creates a larger side yard on the back side of the building, which is useable outdoor space for the residents.
