posed to be moved shall place on deposit with the City of Corpus Christi a cash
deposit of $500, and an affidavit whereby the owner agrees that if the specified
required improvements are not made within the required time period, then the $500
deposit shall be forfeited and the City of Corpus Christi shall retain said deposit,
provided that the Building Code Board of Appeals is authorized to grant extensions
of time not exceeding 180 days for cause beyond the control of the owner upon appeal
in accordance with Section 112. Such retainage of deposit is to help defray the
additional clerical and inspection costs incurred under such circumstances and is not
a penalty and is not preclusive of any remedy otherwise available to the City Of
Corpus Christi to enforce this code. If the necessary improvements are completed
within the required time period, then said $500 cash deposit shall be refunded when
the certificate of occupancy is issued.
2204.10 - Housemover's License Required.

tion shall state the name and address of all persons owning any interest in said house
moving business. Said applicant shall pay at the time of application an annual house -
mover's license fee of $50.
-24-
e
2204.11 - Amount of Housemover's Bond.
The amount of bond required by Section 2204.4 of this code shall be $20,000.
In lieu of said bond in the amount of $20,000,the applicant may file a bond in the
principal sum of $2,000 provided that in addition to said $2,000 bond the applicant
shall file with the City by delivery to the Building Official a public liability
and property damage insurance policy certificate naming the applicant as the assured

the extent of $100,000 for personal injury and $50,000 for property damage for each
accident, and with certificate shall show that said insurance is in force for the
period for which the license is requested. Said person, firm, or corporation may
give as surety upon said bond a good and reliable surety company or may give a
sufficient personal bond with two or more financially responsible persons as sureties.
Before becoming effective, said bond requires the approval of the City Attorney of
the City of Corpus Christi, Texas. Said bond shall also be conditioned that it
shall not be discharged by one recovery thereon, but that the obligation is a
continuing one, effective for all renewals of such license.
2204.12 - Term of License and Renewal.
A housemover's license shall be valid for one year from the date of issuance,
unless sooner revoked. A housemover's license may be renewed at the end of its term
by filing an application for renewal and paying the license fee.
2204.13 - Notification, payments, and revocation of license.
(a) Any licensed housemover shall before moving any house, building, or structure
within the City of Corpus Christi give notice to all persons, firms, or corporations
having poles, lines, wires, or other such fixtures that may be affected along the
route over which said house, building, or structure may be moved, at least 24 hours

automatically cancel the housemover's license of such person, firm, or corporation
engaged in the business of housemoving in the City of Corpus Christi, Texas and a -letter
from the Building Official to such person, firm, or corporation shall be sufficient to
cancel such permit.
-25-
r.
(c) The Building Official may revoke at any time a housemover's license, if
the holder of said license violates the terms of this code or any other ordinance of
the City.
2204.14 - Exemptions:for Moving Small Buildings.

11. A new Chapter'XXXI is hereby added, to read as follows:
"CHAPTER XXXI
EXPOSED, GRADED, UNCOVERED LANDS
SECTION 3101 - GENERAL
(a) Exposed, graded and uncovered lands within the corporate limits of the
City of Corpus Christi, owing to its location on a coastal prairie, and those lands
within 5,000 feet of its said corporate limits, particularly susceptible to denudation
through wind -blowing of soils shall be considered a detriment of the environment, an
extreme annoyance and discomfort to the inhabitants within the City and within the
5,000 foot zone adjacent thereto, and a peril to traffic and, a hazard to the res-
piratory health of the people.
(b) Such lands in actual, present cultivation for agricultural purposes do not
pose a problem of like kind to the City and, in prevailing, good soil management .
practice shall not foreseeably constitute such detriment, problem, peril and hazard.
SECTION 3102 - SCOPE
This Chapter includes within its scope all lands, except lands presently and
actually under cultivation for agricultural purposes, within the corporate limits of
the City as the same may from time to time now and hereafter exist and within five
thousand feet of such corporate limits, and further except for those plots defined
in "Exposed Land."
SECTION 3103 - DEFINITIONS
(a) "Aeolian Soil" is one that is capable of being transported out of place
on the tract or parcel of land where it occurs by a sustained fresh wind, or a wind
of lesser velocity, in a duration of not less than five (5) seconds and by one or
more of such durations within any total.period of two (2) hours outside of the bounding
-26-
property lines within which it was situated prior to any such transportation. An
"aeolian soil" is also any fine gravel, coarse sand, medium sand, fine sand, or very
fine and falling within the soil separate diameter limit ranges taken from the United
States Department of Agriculture as follows:
Fine gravel or very coarse sand 2 to 1 mm.
Coarse sand 1 to 0.5 mm.
Medium sand 0.5 to 0.25 mm.
Fine sand 0.25 to 0.10 mm.
Very fine sand 0.10 to 0.05 mm.
Silt 0.05 to 0.002 mm.
Clay 0.002 to 0.001 mm.
Colloidal clay Below 0.001 mm.
(b) "Exposed Land" is topsoil plowed, turned, graded, or uncovered, other
than land presently and actually in cultivation for agriculture, so that its natural
or artificial cover, if any, has been substantially removed or plowed under, rendering
such land subject to aeolian deposit in measurable quantities or abutting land or
lands. A plot of such land containing an area of less than ten (10) square feet and
situated, at its nearest edge, more than sixty (60) feet from the nearest property
line enclosing such plot shall not be subject to the terms of this ordinance and shall
be deemed not within its scope.
(c) "Fresh Wind" is a wind ranging in velocity from 19-24 mph on the 0-12
Beaufort Scale as modified by the United States Weather Bureau and shall be deemed
to be prima facie evidenced by the Inspector's reported observation of swaying motion
of small trees in leaf or of crested wavelets forming on inland waters where such
observations of such features occur within the subject tract or parcel or within a
radius of 300 feet of a property line of the subject tract or parcel. Alternatively,
a portable anenometer reading shall constitute such evidence.
(d) "Sands"; "Sandy Loams". For purposes of further definition hereunder of
soil textural classification the following rules from the modified Davis -Bennet
Triangle shall apply:
"Sand" or "Sands" contain 80% or more of sand.
"Sandy Loams" contain more than 50% but less than 80% sand and have less than
20% clay.
(e) "Watered" is the sprinkling of water on the exposed land so that the subject
land is completely covered thereby to an average three (3).inches penetration in
-27-
depth below the topsoil surface as evidenced by five (5) equally distanced 6" borings
and whereby such core samples each contain a ratio of not less than 3 parts water
to 10 parts of soil.
SECTION 3104 - TESTS
For purposes of this code a soil shall be deemed prima facie properly classified
if the same is positively tested in conformity with the following described mechanical
analysis or a demonstrably more refined and accurate variant thereof:
Place exactly 100 grams of soil into a pint bottle.
Add 10 cc of a saturated solution of Na2CO3 and fill the bottle three-fourths.
Stopper the bottle and shake it for five minutes in order to bring the soil in
suspension.
Wash the sand sticking to the sides down into the bottle and allow the solution
to stand for about two minutes.
Theoretically, only silt and clay are now in suspension. Carefully pour off
the suspended silt and clay, being careful to lose none of the sand.
Refill the bottle with water, shake vigorously a few times, wash down the
material sticking to the sides of the bottle, and again allow it to stand until all
of the sand has settled. Decant the silt and clay as before, repeating this process
until the supernatant liquid is clear when the sand has settled.
Wash the sand carefully into a large evaporating dish and allow to settle
again, then pour off as much of the water as possible.
Place the dish on a ring stand and heat gently with Bunsen burner until the
sand is dry.
After allowing the sand to cool, separate it into the various separates by
use of sieves arranged in the following order 20 mesh, 40 mesh, 60 mesh, and 80
mesh.
The material on top of the 20 mesh sieve is fine gravel; that on top of the
40 mesh is coarse sand; that on top of the 60 mesh sieve is medium sand; that on
top of the 80 mesh sieve is fine sand; the material passing the 80 mesh sieve is
very fine sand.
SECTION 3105 - OFFENSE DEFINED
It shall be unlawful for any person, as owner or as custodian, to cause or
permit to exist or be maintained exposed land within the corporate limits of the
city within five thousand feet of such corporate limits except lands presently and
actually under cultivation for agricultural purposes containing aeolian soil or
sandy loam therein, subject to transportation as stated in the definition of
-28-
"Aeolian soil," unless watered as herein defined and provided. Every day such person
causes or permits the existence of such unlawful condition shall constitute a separate
offense.
SECTION 3106 - ENFORCEMENT
(a) The Building Official is hereby empowered to go upon any tract or parcel
subject hereof, irrespective of ownership or custody, for the purpose of enforcing
this ordinance, and for the purpose of removing one (1) 100 -gram soil sample, more
or less, not more often than once in a twenty-four (24) hour period as to such tract
or parcel, and may remove, take, and test such sample as herein provided, and may
retain custody of such sample until final disposition of any civil or criminal action
filed in relation thereto or for one (1) year, whichever first occurs, without charge,
damage, debt, or liability therefor, his supervisors, or the City of Corpus Christi
or its officers. After such first occurrence the sample shall be returned to the
owner or custodian of such land upon demand.
(b) By this same police power license the Building Official may enter and
measure, without charge, damage, debt, or liability therefor, the perimeter dimensions

in using wall -mounted dial telephones or towel dispenser, would make the average
reach (on the wall) 48 inches from the floor.
(9) Most individuals ambulating on braces or crutches, or both, or on canes
are able to manipulate within the specifications prescribed for wheelchairs, although
doors present quite a problem at times. However, a crutch tip extending laterally
from an individual is not obvious to others in heavily trafficked areas, and not
as obvious or protective as a wheelchair and is, therefore, a source of vulnerability.
(10) On the average, individuals 5 feet 6 inches tall require an average of 31
inches between crutch tips in the normally accepted gait.
(11) /On the average, individuals 6 feet 0 inches tall require an average of
