GENERAL PROVISIONS & PURPOSES
Subdivision: A division of any tract of land into two or more parts for the purpose of laying out
tracts of land or lots, or for laying out suburban lots or building lots, where the lots may now or in

or other portions intended for public use or the use of purchasers or owners of lots fronting
thereon or adjacent thereto. Subdivision includes re-subdivision or replats. (See Chapter 232,
Texas Local Government Code)
These Subdivision Regulations have been adopted based on the following findings:
{a) The Commissioners Court of Kerr County has the authority to regulate the
subdivision process pursuant to Government Code, §232.001.

sewage facilities within the County and has adopted these Regulations to abate or
prevent the potential pollution, nuisances or injury to public health;
(f) The Commissioners Court of Ken County has considered the potential public
health crisis and diminution in land values that will occur if the demand for
groundwater within the County exceeds the rate that groundwater resources are
replenished within the County and has adopted these Regulations to prevent or
limit such potential injury to public health and land values;

Section IV
VARIANCES
The Court may authorize a variance from these regulations when, in its opinion, undue
hardship will result from requiring strict compliance. In granting a variance, the Court shall
prescribe only conditions that it deems necessary to, or desirable in, the public interest. In making
the findings here-in-below required, the Court shall take into account the nature of the proposed
use of the land involved, existing use of land in the vicinity, the number of persons who will
reside or work in the proposed subdivision, and the probable effect of such variance upon traffic
conditions and upon the public health, safety, convenience and welfare in the vicinity. No variance
shall be granted unless the Court finds:
4.01 That there are special circumstances or conditions affecting the land involved such
that the strict application of the provisions of these Rules & Regulations would deprive the
applicant of the reasonable use of his land; and
4.02 That the variance is necessary for the preservation and enjoyment of a substantial
property right of the applicant; and
4.03 That the granting of a variance will not be detrimental to the public health, safety
or welfare, or injurious to other property in the area; and
4.04 That the granting of a variance will not have the effect of preventing the orderly
subdivision of other land in the area in accordance with the provisions of the Rules & Regulations.
Such findings of the Court together with the specific facts upon which such findings are found
shall be incorporated into the official minutes of the Court meeting at which such variance is
granted. Variances maybe granted only when in harmony with the general purpose and intent of
these Rules & Regulations. Monetary hardship to the subdivider, standing alone, shall not be
deemed to constitute undue hardship.
