This map defines residential <br /> density limits for each of the water supply watersheds. He explained that the vertical striping <br /> indicates watersheds with lower density limits. For instance, University Lake is one dwelling unit <br /> per five acres of land, and Cane Creek is one dwelling unit per two acres of land. After reviewing <br /> the other slides, he said there are a lot of reasons why there are no density limits for non- <br /> residential developments. Generally, commercial projects are a single parcel, and there's typically <br /> not a multi-building approach. He explained that floor area ratio is used for commercial <br /> developments, which is essentially the footprint of the building divided by the footprint of the parcel <br /> itself. <br /> Commissioner Greene said she didn't realize there were floor area ratios in the UDO. She <br /> asked if those are just for commercial developments and how they are calculated. <br /> Cy Stober said they can be found in Article 3. He said there is a table and page for every <br /> one of the zoning districts, and, except for the conditional districts, they nearly all have floor area <br /> ratios. He said generally, the governing regulations for most residential development are <br /> impervious surface or density, so that usually comes before floor area ratios are consulted for a <br /> residential project. <br />
