Dear Dennis:
re: Vistas of Coppell
The following shows comparisons of 4 scenarios - the project as you have proposed it, the
project as it would comply with the Coppell PD District, the project if treated as 4 separate PDs,
and the project if treated as a single PD for Phases 1 through 3 and a single PD for Phase 4.
I used 3.4 du/ac for the 66'x110' lots and 5.2 du/ac for the 50'x100' lots. While the results are
only an approximation of lot yield, they indicate rather dearly that the plats you are submitting
will not meet the PD rule requiting 65 % of all lots within a PD to comply with SF-7 standards.
Based on our analysis, it is likely that, as a single PD, 322 lots will be the maximum you can
achieve on Phases 1 through 3, of which only 146 lots can be less than 7000 square feet in area.
As stated in our written comments, sent to you prior to the DRC meeting, a more desirable
arrangement would be separate PDs for each phase. This would reduce the lot yield on Phases
1 through 3 to a probable 310 lots, of which 108 could be less than 7000 square feet in area.
Another alternative, which the Planning and Zoning Commission might consider, is separate PDs
for the school site and housing area. This, however, would yield approximately the same lot
count.
Until the issue of the PD is resolved by City Council, continuing work on the preliminary plats
seems rather unproductive...particularly if they won't meet zoning criteria for a PD of any sort.
Please call if you have questions.
Sincerely,
Pert Virtanen
Assistant Director of Planning and Community Services
