within said Chapter to read as follows:
B. Pavement Thickness Requirements
The following specifies minimum standards required for the pavement and subgrade design for
roadways and alleys within the City. These minimum standards are not intended to replace the
professional judgment of the Geotechnical Engineer for any specific project. The standards may
need to be expanded or modified on a case by case basis as determined necessary and appropriate
by the Geotechnical Engineer, and as approved by the City Engineer.
All roadways and alleys shall have a geotechnical investigation and pavement and subgrade design
performed. Results of the geotechnical investigations, engineering analyses, and
recommendations shall be presented in a Geotechnical Report for Roadways ("Report'). The
Report and any subsequent re-evaluations or supplemental reports shall be signed and sealed by a
Licensed Professional Engineer in the State of Texas trained and qualified to provide
geotechnical engineering analysis and pavement and subgrade design recommendations.
(1) Residential/Local Street, Residential/Estate Street and Alley Construction
The subdivider shall, at his own cost and expense, pay for constructing all residential
streets and alleys within his subdivision and one-half (1/2) of all existing and/or
proposed perimeter streets. Monies for the construction of the one-half (1/2) street
shall be placed in an escrow account if the construction of the street is to be deferred
to a later date.
A six inch (6") thickness of three thousand six hundred (3,600) p.s.i. reinforced
concrete pavement on a compacted sub -base shall be required. All steel reinforcing
shall be deformed No. 3 bars on eighteen inch (18") center both ways or No. 4 bars on
twenty-four inch (24") centers both ways.
Where the plasticity index of the soil is twelve (12) or greater, stabilization of the sub -
grade, eight inches (8") thick with six percent (6%) hydrated lime by weight, shall be
required. Compaction of the lime stabilized sub -grade shall be according to the
Standard Specifications, Division 4, Item 4.6., [Section] 4.6.4(d).
Unless otherwise approved by City, the concrete shall be placed using either forms or
slipform paver. Concrete strength shall be increased to four thousand (4,000) p.s.i. for
hand poured concrete.
Any proposed pavement section of lesser thickness or alternate materials shall be fully
documented by the design engineer to substantiate the fact that such alternate will
provide an equivalent capacity for the pavement noted above and must be approved
by the city.

The subdivider shall, at his own cost and expense, pay for constructing all streets and
alleys within his subdivision and one-half (1/2) of all existing and/or proposed
perimeter streets. Monies for the construction of the one-half (1/2) street shall be
placed in an escrow account if the construction of the street is to be deferred to a later
date.
Collector streets and alleys shall, at a minimum, be designed and constructed with
eight -inch (8") thickness of four thousand (4,000) p.s.i. reinforced concrete pavement
on a compacted sub -base. All steel reinforcing shall be deformed No. 4 bars on
eighteen inch (18") centers both ways.
Where the plasticity index of the soil is twelve (12) or greater, stabilization of the sub-
base with an eight inch (8") thickness of six percent (6%) hydrated lime by weight
will be required. Compaction of the lime stabilized sub -grade shall be according to the
Standard Specifications, Division 4, Item 4.6., Section 4.6.4(d).
Unless otherwise approved by City, the concrete shall be placed using either forms or
slipform paver. Concrete strength shall be increased to four thousand five hundred
(4,500) p.s.i. for hand poured concrete.
Any proposed pavement section of lesser thickness or alternate materials shall be fully
documented by the design engineer to substantiate the fact that such alternate will
provide an equivalent capacity for the pavement noted above and must be approved
by the city.
(3) Major or Secondary Thoroughfare Construction
On roadways, adjacent to the proposed subdivision, that are designated to be major or
secondary thoroughfares (except Class A Loop Highway), the subdivider shall be
required to construct, at his own cost and expense, one-half (1/2) of the street section,
up to a width of twenty-four feet (24% measured to face of curbs, with integral curbs
on each side.
Where thoroughfares traverse a subdivision, the subdivider shall be required, at his
own cost and expense, to construct a twenty-four foot (24') wide section on each side
of the roadway.
Thoroughfares shall be designed and constructed with a nine inch (99") thickness of
four thousand (4,000) p.s.i. reinforced concrete pavement on a compacted sub -base.
All steel reinforcing shall be deformed No. 4 bars at eighteen inch (18") centers both
ways.
Where the plasticity index of the soil is twelve (12) or greater, stabilization of the sub -
grade, ten inches (6 10") thick with six percent (6%) hydrated lime by weight, shall be
required. Compaction of the lime stabilized sub -grade shall be according to the
Standard Specifications, Division 4, Item 4.6., Section 4.6.4(d).
Unless otherwise approved by City, the concrete shall be placed using either forms or
slipform paver. Concrete strength shall be increased to four thousand five hundred

Any proposed pavement section of lesser thickness or alternate materials shall be fully
documented by the design engineer to substantiate the fact that such alternate will
provide an equivalent capacity for the pavement noted above and must be approved
