Sonya,
In regard to your questions about our planned unit development request, I ran some calculations. The subject
property(s) total is 26.34 acres. In quantifying the non-buildable area on the development proposal, the natural slope
area is 4.27 acres (185,860.71 sf) and the Ten Mile Drain, which fully resides inside our property lines is 2.61 acres
(113,663.65 sf). Also, as our property runs to the centerline of Lake Hazel Road, and regardless whether we made an
application for development, ACHD would have reduced our frontage by 0.38 acres (16,682.06 sf). The total unbuildable
set aside would be 7.26 acres.
The gross density subject to PUD approval should be 157 du divided by 19.08 acres (26.34-7.26) = 8.23 du/acre
The net density calculated as 19.08 less 5.03 acres of new street right of way, less 4.52 acres of openspace/common lots
= 16.48 du/acre.
I believe these numbers illustrate that our gross & net densities fall into line with the comprehensive plan designation
for the property (MHDR) of 8-12 units per acre. Please let me know if this favorably answers your questions. I can
certainly bring my calculation sheets in and prove up the numbers if you like. Thank you.
