Section 309. - Lot size averaging.

Within an Overlay District or redevelopment Character Area, where unique site specific conditions exist, such as an irregular shape or other unique conditions, an infill developer or subdivider may propose and the city may approve a flexible development incentive called lot size averaging.

In order to apply this variance, the proposed residential infill development project must meet the following requirements:

1.

The average lot area of all lots within the subdivision meets the minimum lot size for the zoning district in which the project is located.

2.

No lot shall be reduced to less than 80 percent of the required minimum lot size for the applicable zoning district.

3.

For purposes of calculating average lot size, abutting undivided and undeveloped property under the ownership of the infill subdivider at the time of infill subdivision shall not be included in such calculation.

Section 323. - Combination of review and approval processes.

The process of site design and architectural review for individual development may be combined with the subdivision platting process required by the city development regulations. At the option of the development applicant, an applicant may submit a conceptual lot platting plan and defer the plat approval process until a later date, but if so, the applicant is still responsible for submitting information required by this article with respect to proposed lot boundaries as a part of the site design and architectural review process, so that subdivision lot design and specific residential development proposals can be considered as a whole.

In considering the compatibility and appropriateness of residential, commercial, and mixed-use development within the city, it is important that the city consider not only the proposed lot lines and lot platting configurations, but also the specific development types proposed on the lots. The process for acting on infill residential development projects is accomplished by filing information required for both site design and architectural review and information required for applications for plat approval with proposed infill variances proposed concurrently to the Director and City Manager.
