SECTION 1 - PURPOSE AND INTENT - The design and function of streets and
roadways encompasses a sophisticated product of many variables and con-
siderations, which include but are not limited to the following:
1. Type of land use served (i.e., residential, commercial, industrial,
etc.).
2. Type of development density and intensity of land use served (i.e.,
low, medium and high, intensive and extensive).
3. Street function (i:e., Major Thoroughfares, Secondary Thoroughfares
Collectors) and Local Streets).
4. Design speed.
5. Traffic flow and corresponding characteristics as related to public
safety and convenience.
6. Ability to accommodate the maneuverability and circulation of
emergency and service vehicles.
Land and related improvements cost.
8. Construction and maintenance costs.
The purpose and intent of this ordinance therefore, is to improve traffic
Q circulation and flow, provide for and protect the public safety, establish
greater public convenience, develop a more thorough public understanding
and realization of street and roadway systems (and their respective functions
and related components), and to provide,necessary guidelines for public and
private entities in the design and construction of streets, roadways and
drainage facilities. The design standards herein contained are outlined as
a municipal policy guide in effectuating the City of Southlake's "Thorough-
fare and Circulation Plan."
SECTION 2 - GENERAL INFORMATION
2.1 PLANS AND SPECIFICATIONS: Plans and specifications prepared by a
registered professional engineer in the State of Texas shall be required for
all proposed construction of street and drainage facilities in the City. The
plans shall include but not be limited to:
a) Plat of the proposed addition (if a new development) at a scale
not less than 1" = 200 feet showing all property lines, lots and blocks.
b) Topographic map at a scale not less than 1" = 200 feet with con-
tour intervals not exceeding five (5) feet. A drainage area map shall be
prepared utilizing the topographic map.
c) Plan-profile drawings of all proposed improvements at a scale of
1" = 40 feet.
1
2.2 All plans shall be approved by the City Engineer prior to con-
struction. If part of a new development three (3) complete sets of approved
plans and specifications shall be furnished to the City at the expense of
the developer. Upon completion of construction, one set of "As Built" re-
producible tracings of the complete project shall be furnished to the City
at developer's expense.
SECTION 3 - DEFINITIONS, STREET CLASSIFICATIONS AND FUNCTIONS
3.1 STREET - A "street" is defined as all property owned by the public
either through acquisition or dedication by private sources) for the primary
purpose of vehicular movement and circulation, which is contained within fixed
boundaries commonly referred to as right-of-way (R.O.W.) lines, and in which
traveled roadways exist, along with various service utilities (i.e., water,
sewer, telephone, gas, electric utilities, etc.) and sidewalks for pedestrian
circulation.
3.2 ROADWAY - A "roadway" is defined as the traveled portion of a street
upon which vehicles traverse and circulate, and includes the area from back-to-
back of the outer curb lines, or where curbs do not exist, said roadway in-
cludes the traveled area from the outer edges of the surfaced and prepared
portion of the roadway, excluding shoulders, etc.
3.3 CUL-DE-SAC STREET - A "cul-de-sac" street is a public or private
street in which one en (outlet) intersects at right angles (or near right
angles) with an adjacent public or private street, and the opposite terminal
end culminates in a turnaround (cul-de-sac). The main characteristic of a
cul-de-sac street provides for only one traffic outlet to an adjacent in-
tersecting street and therefore prohibits through traffic.
3.4 PRIVATE ROADWAYS AND/OR DRIVES - These are similar to public streets
and roadways except that ownership and maintenance is privately used and re-
tained and not dedicated to the public for general public use and maintenance.
3.5 EFFECTIVE ROADWAY PAVING WIDTH - The distance between the inside
curb faces of a roadway; or where curbs do not exist, the distance (width)
to the outer edge of the roadway paving (exclusive of shoulders).
3.6 DENSITY - As referred to in these standards are defined as follows:
a. Low Density Development - 2.0 (or less) dwelling units per acre.
b. Moderate Density Development - 2.1 to 7.0 dwelling units per
acre.C. Medium Density Development - 7.1 to 19.0 dwelling units
per acre.d. High Density Development - 20 or more dwelling units
per acre.3.7 MAJOR THOROUGHFARES - Generally comprise federal
and state numbered highways and other significant traffic corridors, and are
stratified as follows:a. Principal Arterials - Highest
traffic volume corridors.b. Minor Arterials - Interconnects with, and
augments,
the "Principal 10 Arterial" System at a somewhat lower level
of
These thoroughfares primarily serve through traffic on a continuous route
Q within the city for purposes of linkage with other urban areas and significant
traffic generators outside the city, and thus form an integrated network of
providing inter city/county service. The intention of these streets is to move
all types of traffic (autos, buses, trucks, etc.) at moderate speeds with mini-
mum interruption. On-street parking is prohibited. Of secondary importance
is the land service function abilities and capabilities. Access control is
normally dictated by city, state and county policy. Major thoroughfare streets
require sufficient R.O.W. widths to accommodate additional traffic lanes or other
roadway modifications as future traffic demands may dictate.
3.8 SECONDARY THOROUGHFARES (COLLECTOR STREETS) - These streets, often
called "Collector Streets", accommodate the dual functions of collecting in-
ternal traffic circulation (from local streets) within a specific area(s) of
the city for movement from that area(s) to a "Major Thoroughfare" street (at
appropriately spaced points) for dispersal along the "Major Thoroughfare."
The primary consideration of a "collector" street is in accommodation of major
traffic flow. Land access and service to abutting private property is general-
ly of secondary importance. Design speeds are low to moderate and curb park-
ing is discouraged where possible, unless sufficient traffic and parking lane
widths are provided.
a. "Principal Collectors" - These streets form a somewhat continuous
road network anrally comprise the boundaries of neighborhoods. They
are, therefore, designed to accommodate higher traffic volumes than "Minor
Collectors." Land access and service to abutting private property is ofi
secondary importance. These streets require a sufficient R.O.W. width to
accommodate additional traffic lanes as future demands dictate. Median strips
of not less than 16 to 20 feet in width are required for left turn movements.
b. "Minor Collectors" - It is not considered necessary for "Minor Col-
lectors" to form a continuous system as it would induce a tendency for traffic
to use this type of street as a "Principal Collector" or "Thoroughfare," thus
negating one of the basic principles of traffic planning which is to keep
through traffic confined to higher order streets. "Minor Collectors" nor-
mally require less R.O.W. width than "Principal Collectors" due to function,
and normally carry lower traffic volumes. These streets form the boundaries
of sub-neighborhoods and often serve to separate development density or in-
tensity.
3.9 LOCAL STREETS - Local streets (sometimes referred to as "Residential",
Commercial Industrial" or "Minor" streets) serve the primary purpose and func-
tion of providing access to adjacent private property. These streets, along
some point in their routing intersect with "secondary thoroughfares", and
sometimes even "major thoroughfares." Normally, "local" streets in residential
areas (and where neighborhood-serving commercial activities are present) are
relatively narrow in width and of limited length. This street classification
f also includes cul-de-sac streets. Local streets which serve higher intensive
developed areas (i.e., general commercial, high density apartments, and in-
dustrial facilities) should be designed to a higher classification'standard,
as their traffic volumes (due to adjacent traffic generators) more closely
reflect "collector" or "thoroughfare" type streets.

SECTION 6 - STORM DRAINAGE DESIGN STANDARDS
6.1 GENERAL STORM SEWER STANDARDS: An adequate storm sewer system
consisting of inlets, pipes, and other underground and above ground drainage
structures with approved outlets shall be constructed where the runoff of
storm water and the prevention of erosion cannot be accomplished satisfac-
torily by surface drainage facilities.
6.2 DESIGN CRITERIA: Data shall be submitted as directed in this
Section and under Developer's Policies for storm drainage installation for
the City of Southlake, Texas. All subdivision development shall be subject
to this criteria. Drainage problems will be solved by the use of the RATIONAL
METHOD:
Formula: Q = CIA: where
Q = the storm flow at a given point in cubic feet per second
c.f.s.).
C = a coefficient of runoff representing the ratio of rainfall
to peak runoff.
I = the average intensity of rainfall in inches per hour for a
period equal to the time of flow from the fartherest point
of the drainage area to the point under consideration.
Developed from Technical Paper No. 40, "Rainfall Frequency
Atlas of the United States", May 1961 by U. S. Weather Bureau.)
A = the area in acres that is tributary to the point of design.
I A. Minimum Inlet Time
Residential - 15 minutes
Industrial - 10 minutes
Commercial - 10 minutes
Water assumed to be 8" deep with an 8" curb on a 30' street with a
6" crown and 6" deep with a 6" curb on a 30' street with a 6" crown.
Where curb elevations are split the carrying capacity shall be ad-
justed according to recognized engineering procedures. Wider streets
shall be treated in a similar manner.

7.2.3.8 TWO OR MORE UNITS: On Assessment Paving projects, in the
event the project consists of two or more units, it is specified that one or more
of the units may be deleted by the City Council after the Benefit Hearing as
pro-vided by law, and such deletions will in no way affect the contract as a
whole,nor will it affect the unit prices bid on other units. Should it develop
during construction that some items of work become necessary on any particular
unit and those particular items of work were not bid in that unit, then the
agreed unit price for the work will be the lowest unit price bid for the same work
on any other
units.Should it develop that the City deems it necessary to alter the
paving width by increasing or decreasing the roadway width, the resulting
variations in affected quantities will in no way affect the contract as a whole and
will not affect any other unit, nor will it affect any unit prices bid as shown

is provided for acceptable materials complete in place, and materials rejected
due to improper fabrication or excess quantity or for other reasons within
the control of the Contractor will not be paid for, regardless of the
quantities or dimen-sions shown on the plans. The City Engineer, when requested,
will check any or all material orders prepared by the Contractor, but such
check will not relieve the
Contractor ofresponsibility.7.2.5.5 CONFORMITY WITH PLANS: Finished surfaces

to report to the City Engineer as to the progress and quality of the work
as it is being performed;to report whenever it appears that the materialsfurnishedandtheworkper-formed by the Contractor fail to fulfilltherequirementsofthespecifica-tions and contract; and also to call the attentionoftheContractortoanysuchfailureorotherinfringement. Such
inspection will not relieve the Contractor from any obligation to perform the
work in accordance with the requirements of the specifications. In case

examined prove unacceptable, the uncovering and/or removing and the replacing of
the covering or the making good of the parts removed shall be at the Contractor'
s
expense.
i 7.2.5.11 FEDERAL INSPECTION: When the United States Government

in which case the City, at its option, may take over and use the
Contractor'
s
until the work contracted for is completed, allowing reasonable rental
therefor; or the City may purchase material, tools and equipment and em-
ploy labor or contract with any other individual firm or corporation to
perform the work. All costs and expenses incurred thereby shall be charged
against the defaulting Contractor and the amount thereof deducted from any
payment due or that may become due him, or shall be charged against the con-

entire amount of each class of work performed and as to the value
thereof.7.2.6 CONTROL
OF MATERIALS7.2.6.1 SOURCE OF SUPPLY AND QUALITY OF MATERIALS: The
source of supply for each of the materials shall be approved by the City
Engineer before de-livery is started and, at the option of the City Engineer,

sources of supply previously approved do not produce uniform and
satisfactory products or results, or if the product from any source proves unacceptable
at any time,the Contractor shall furnish materials from other
approved sources. Only materials conforming to the requirements of these
specifications and approved by the City Engineer shall be used in the work. All
materials being used are subject to inspection or a test at any time during
their preparation or use. Any materials which have been tested and accepted at
the source of supply may be subjected to a check test after delivery,

of the specifications will be rejected. Material which, after approval, has in
any way become unfit for use shall not be used in the work. All materials
used shall be new except when specifically provided that salvaged material
may be used.Approval of materials by the City Engineer shall not
relieve the Contractor of liability or duties hereunder if the materials furnished
prove
to be defective.Preference shall be given by the Contractor to the use
of local materials when the cost or quality of such local materials are
equivalent to
those obtainableelsewhere.7.2.6.2 SAMPLES AND TESTS: All
materials, before being incorporated into the work, shall be subject to inspection, testing

wooden plat-forms or other hard, clean surfaces that are not on the ground.
They shall be placed under cover when so directed. Stored materials shall be
so located as to facilitate
prompt inspection.Cement shall be stored in a suitable weatherproof shelter, with
a floor a minimum distance of one (1) foot above the ground, which will
protect the cement from moisture, deterioration and loss, and placed in such a
manner as to permit easy access for proper identification and inspection for
each
ship ment.All aggregates shall be handled and stored in such manner at
to prevent separation and contamination by
foreign substances.7.2.6.5 DEFECTIVE MATERIALS: All materials not conforming
to the re-quirements of these specifications shall be considered as
defective, and all such materials, whether in place or not, shall be rejected and
shall be re-moved immediately from the site of the work unless they
are permitted to remain by the City Engineer. Rejected materials, the defects
of which have been subsequently corrected, shall have the status of
new material; however,`such previously rejected material which has been corrected
shall not be used until approval has been given by the City Engineer.
Upon failure on the part of the Contractor to comply with any order of the
City Engineer made under the provisions of this item, the City Engineer will
have
the
to remove and replace defective materials and to deduct the cost of the

Engineer at least twenty-four 24) hours before beginning work at any point. He shall
not open up work to the detriment of work already begun. The
Contractor shall conduct his opera-tions so as to impose a
minimum interference to the traffic.The Contractor shall at all times cooperate
with work forces engaged at or near the site, whether they are City forces
or employed by other contractors or public utilities, so that the construction of
the entire project may be carried on to the earliest practical completion
with the least practical in-terference with
other
contract
A
7.2.8.3 WORKMEN AND EQUIPMENT: The Contractor shall use local
labor 10 if available. The Contractor will be allowed to bring in from outside
the City of Southlake his key men and superintendent. All workmen employed
by the Contractor shall have such skill and experience as will enable them
to properly perform the duties assigned to them. The Contractor shall
furnish such suitable machinery, equipment and construction forces as may be
neces-sary in the opinion of the City Engineer for the proper prosecution of
the work, and failure to do so may cause the City Engineer to withhold all
es-timates which have or may become due to the Contractor, or the City
Engineer may suspend the work until the requests are complied
with.7.2.8.4 TEMPORARY SUSPENSION OF THE WORK: The City Engineer
will have authority to suspend the work, in whole or in part, for such period

The City Engineer will furnish the Contractor upon request with a monthly
statement on forms furnished by the City, showing the number of days charged
during the month,the total number of days allowed in the contract, and
the days remaining in the contract. The Contractor will be allowed ten (10) days
in which to protest the correctness of the statement; otherwise, the
statement will stand.When adjusting the time for completion, the days on which the
work has been suspended by an act or omission of the City, and not by failure
of the Con-tractor, shall be allowed to the Contractor and excluded
from the computation in making said adjustment, all of which shall be determined
by the Engineer and certified thereto in writing. The decision of the
Engineer shall be binding and conclusive on both parties to the contract.
If the satisfactory completion of the contract shall require unforeseen work or
work and mate-rials in greater amounts than those set forth in the
contract, then additional working days or suspension of time charge will be allowed
the Contractor equal to the time which, in the opinion of the City Engineer, the work
as a
whole isdelayed.7.2.8.6 FAILURE TO COMPLETE WORK ON TIME: The
Owner and the Contractor agree that it will be most difficult or impossible to
ascertain the amount of damages that will be sustained by the Owner if the
Contractor fails to complete the work in the allotted time, but they both agree that
the Owner would sustain substantial damages in such event. Accordingly, if
the Contractor fails to complete the contract in the working or calendar days
specified, a time charge shall be made for each day thereafter, not as a
penalty

specified. All longitudinal measurements for surface areas will be made along the actual surface
of the roadway and not horizontally, and no deduction will be made for
structures in the road-way having an area of nine (9) square feet or
less. For all transverse measurements for areas of base courses, surface
courses and pavements, the dimensions to be used in calculating the pay areas will
be the neat dimen-sions and shall not exceed those shown on the plans or
as ordered in writing Q by the City Engineer. All materials which
are specified for measurement by the cubic yard in vehicles will be hauled in
approved vehicles and measured therein at the point of delivery on the roadway.
Vehicles for this purpose may be of the type or size satisfactory to the
City Engineer provided the body is of such type that the actual contents may
be readily and accurately determined. The Inspector may reject all loads not
hauled
in such approved vehicles.In those items which provide for payment by "
Plan Quantity," the measure-ment of such quantity shall represent an accurate
calculation, made by the method described in the governing specifications, and may
or may not represent the exact quantity of material moved or handled during
the
execution ofthe contract.7.2.9.2 SCOPE OF PAYMENT: The
Contractor
shall accept the compensation 1 as provided in the contract in full payment for
furnishing and paying for all materials, supplies, subcontracts, labor,

Contractor to repair or remove, at his own expense, the defective parts of
the construction or to replace any defective materials used in the con-
struction, and to be responsible for all damages due to such defects if
such defects or damages are discovered on or before the final inspection
and acceptance of the work.
No payment payable under the contract or any part thereof, except for
the estimate for the first month or period, shall become due and payable,
if the City Engineer so determines, until the Contractor shall satisfy the
City Engineer that he has fully settled or paid for all materials and equip-
ment used in or upon the work, subcontracts and labor done in connection
therewith; and the City, if it so determines, may pay any or all such
balances wholly or in part and deduct the amount or amounts so paid from
any monthly or final estimates, except the first estimate.

the construction of the street improvements. The necessary assessment
certificates and ordinances will be prepared and adopted by the City Council.
It will be the responsibility of the City to collect any or all assessments
from the property owners. The Contractor shall take into consideration that
assessment paving projects may require additional time for legal proceedings
before the work order can be issued for construction. A work order for the
beginning of construction of assessment projects will not be issued until
at least fifteen (15) days have elapsed from the date of the adoption of
the ordinance levying assessments and closing the benefit hearing.

construction
opera-tions.D. Grubbing: On areas required for construction of
embankments, all stumps, roots, etc., shall be removed to a depth of at least one (
1) foot below the existing ground surface, and in areas of excavation
all stumps,roots, etc., shall be removed at least one (1) foot below the bottom
of the stabilized subgrade, pavement base, or concrete slab, whichever
is greater
in depth.E. Cleaning Up: All materials cleared and grubbed shall
be disposed of as directed by
the Engineer.7.3-
110 STREET EXCAVATION A. Description: This item shall consist of all
the required excavation,the removal, proper utilization or disposal of all
excavated materials; and the construction of all embankments, and the shaping and
finishing of all earthwork in conformity with the lines and grades established
by the Engineer as shown on
the
approved
B. Excavation: All excavation shall be in accordance with the lines,
grades, and typical sections as shown on the plans or established by the
Engineer. Unless otherwise shown on the plans, or established by the Engineer,
street excavation will, be made to the subgrade of the roadway and finished
grade of parkways.
Where excavation to grades established in the field by the Engineer would
terminate in unstable soil, the Engineer may require the Contractor to remove
the unstable soil and backfill to the required grade with suitable material
compacted, in an approved manner, to a density equivalent to the density re-
quired for adjacent material.
Where excavation to the grade established in the field by the Engineer
terminates in loose or solid rock, the Contractor may be required to extend
the depth of excavation six (6) inches and backfill with select material
compacted, in an approved manner, to a satisfactory density. Subject to
the approval of the Engineer, the select material backfill may be obtained
from any point within the right-of-way where suitable backfill material is
available.
C. Provisions for Drain: If it is necessary in the prosecution of
the work to interrupt the natural drainage of the surface, or the flow of
artificial drains, the Contractor shall provide temporary drainage facilities
that will prevent damage to public or private interests, and shall restore
the original drains as soon as the work will permit. The Contractor shall
be held liable for all damages which will result from neglect to provide for
either natural or artificial drainage which his work may have interrupted.
D. Embankment: Embankments shall be constructed in accordance with
the lines, grates and typical sections as shown on the plans or established
by the Engineer.
Prior to construction of embankments the ground surface upon which embank-
ments are to be constructed shall be scarified in furrows uniformly spaced so
that at least fifty (SO) percent of the surface will be broken to a depth of
at least four (4) inches.
Embankments shall be constructed of suitable materials and shall be
placed in successive horizontal layers of not more than eight (8) inches
in depth, loose measurements for the full width of the embankment and in
such lengths as designated. Stumps, trees, rubbish, vegetation or other
unsuitable materials shall not be placed in embankments. All construction
traffic shall be uniformly distributed over the entire surface of each layer
of the embankment.
Each layer of the embankment and the completed embankment shall be com-
pacted to not less than 90% density as per AASHO designation T180. No suc-
cessive layer shall be placed until the layer under construction has been
completed to the satisfaction of the Engineer.

IN
After a section of the embankment has been completed it shall be main-
tained to grade and cross section by blading when and to the extent required.
Embankments placed over and adjacent to pipes, culverts, and other struc-
tures shall be of suitable materials, and shall be placed in successive hori-
zontal layers of not more than eight (8) inches in depth, loose measurement,
and each layer uniformly mixed, pulverized and thoroughly compacted to the
satisfaction of the Engineer by the use of rakes, hand tamps, and/or other
approved methods. Special care shall be taken to prevent any wedging action
against the structure. This method of consolidation and compaction shall be
used for such distances along embankment adjacent to structures as may be
necessary and in other areas where blading and rolling would be impractical.
E. Excess Excavation: Unstable street excavation, stumps, trees, rubbish,
unsuitable material and suitable street excavation in excess of that needed for
construction shall be disposed of as directed by the Engineer and at a site
approved by the Engineer. In general suitable excess street excavation will
be used in the construction of parkways, widening of embankments, flattening
of slopes, etc., but if necessary to waste any material, it shall be disposed
of in such a manner as to present a neat appearance and to not obstruct proper
drainage or cause injury to street improvements or to abutting property.
F. Compaction (Density) Tests: Before any base material or pavement is
placed on the subgrade, compaction or density tests shall be made by an
approved independent testing laboratory. The field density test results
shall be not less than 90% density as per AASHO designation T180. At least two
2) field density tests will be made on each 1000 square yards of prepared
subgrade or fraction thereof. Additional tests may be required at question-
able areas.
The Contractor will be responsible to furnish all test results, as re-
quired, directly to the City's Engineer. The city will select the testing
agency for approval, however, payment for all density tests will be made by
the Contractor.

Trench backfill shall be classified into two (2) types: (a) Within the
Right-of-Way of Public Streets, (b) Outside of the Right-of-Way of Public
Streets.
a) Trench Backfill within the Right-of-Way of Public Streets.
1. Pit-run sandy gravel or field sand of a quality satisfactory
to the Engineer, shall be placed in the bottom of the trench preceding the
placing of precast concrete pipe. This bedding shall be placed such that it
will be slightly above the underside of the pipe after compaction, and to a
depth between three (3) and six (6) inches under the concrete pipe. After
compaction the bedding shall be fine graded. The thickness of the beddingplacedunderthepipeshallbereasonablyuniform, and shall be compacted bytamping, and with the addition of water where necessary.
2. After concrete pipe has been laid, and joints made, pit-run
sandy gravel or field sand as above specified shall be placed under the haunches
of the pipe, on the sides of the pipe, and to a height above the pipe such that
the material will be at least twelve (12) inches above the top of the pipe after
the backfill has been settled. The backfill shall be placed equally on bothsidesofthepipeinorderthatthepipewillnotbedisplaced, and if neces-
sary the pipe shall be blocked against the sides of the trench to insure that
no displacement occurs. The backfill placed under the haunches of the pipeshallbeworkedintoplacebyhandduringthetimeitisdepositedinthe
trench. After the backfill has been placed adjacent to and over the pipe,then it shall be compacted by jetting with water, with a one (1) inch pipeofsufficientlengthtoreachthebottomofthepipeandsufficientwater
pressure to insure that the surrounding materials will be quickly and thor-
oughly flooded.
When the surrounding materials are of such a nature that they do
not permit the rapid drainage of the jetting water, the Contractor may be
required to provide, at his cost, a sump and pump at the downstream end of
the trench to remove the accumulated water.
3. The remainder of the trench shall be backfilled in such a
manner (jetting, mechanical tamping, rolling, etc.) as to obtain in all
cases a density not less than ninety (90) percent of the modified density as
determined in accordance with AASHO T180. After sufficient time has elapsedforthefreemoisturetobegonefromthepit-run sandy gravel or field sand
placed as outlined above, the remainder of the trench shall be backfilled
with material excavated from the trench, except that no rocks larger than
two (2) inches shall be used in the backfill, and material from rock or
shale excavation shall not be used. At locations where the excavated mate-
rial is from rock or shale formations, or where the material is such that
it is not suitable for compaction by the method being used, then the mate-
rial shall be disposed of and acceptable substitute backfill material shall
be provided and placed as required.
a. If jetting is selected as the method of compaction, the
procedure outlined below is the minimum acceptable.
50
I
r
The backfill shall be placed in layers not exceeding four
4) feet in thickness loose, and each layer shall be thoroughly jetted with
water after the earth backfill has dried out reasonably well; then the entire
backfill, including the pit,-run gravel, or field sand shall be jetted a final
time. Jetting operations shall be done with a pipe of sufficient length to
reach the bottom of the storm drain pipe, with adequate hose and sufficient
pressure to do the work thoroughly and properly; the jetting pipe shall be
applied so that the top of the backfill is settled first and then shall pro-
ceed further into the material until the bottom of the pipe is reached. The.
jetting pipe shall be used on both sides of the storm drain pipe and at in-
tervals of not more than five (5) feet along each side.
b. If mechanical tamping is selected as the method of com-
paction, the procedure outlined below is the minimum acceptable.
The backfill material shall be placed in layers not exceeding
six (6) inches loose thickness. The moisture content of the material being
tamped shall be uniform and near the optimum moisture content for the mate-
rial. In case the material being placed does not have the proper moisture,
then the material shall be dried out or additional moisture shall be added
by satisfactory methods such that the additional water is distributed uni-
formly throughout the material being placed. The layers of backfill shall
be reduced in thickness when satisfactory compaction cannot be obtained with
the equipment being used.
C. If rolling is selected as the method of compaction, the
procedure outlined below is the minimum acceptable.
Rolling equipment shall not be placed in the trench until at
least twenty-four (24) inches of material have been placed over the top of
the storm drain pipe, at least eighteen (18) inches of which shall conform
with these backfill specifications as related to the minimum Proctor Density.
The backfill material shall be placed in layers not exceeding eight (8) inches
loose thickness. The moisture content in the material being rolled shall be
uniform and near the optimum moisture content for the material. In case the
material being placed does not have the proper moisture, then the material
shall be dried out or additional moisture shall be added by satisfactory
methods such that the additional water is distributed uniformly throughout
the material being placed. The layers of backfill shall be reduced in thick-
ness when satisfactory compaction cannot be obtained with the equipment being
used.
4. In the case where the storm drain is located underneath per-.
manent pavement the entire trench excavation shall be backfilled with pit-
run sandy gravel or field sand. This material may be placed in loose layers
not exceeding four (4) feet in thickness and shall be jetted as outlined
above.

b) Trench Backfill Outside of the Right-of-Way of Public Streets.
1. Pit-run sandy gravel or field sand of a quality satisfactory
to the Engineer, shall be placed in the bottom of the trench preceding the
placing of precast concrete pipe. This bedding shall be placed such that it
will be slightly above the underside of the pipe after compaction, and to a
depth between three (3) and six (6) inches under the concrete pipe. After
compaction the bedding shall be fine graded. The thickness of the bedding
placed under the pipe shall be reasonably uniform, and shall be compacted
by tamping, and with the addition of water where necessary.
2. After the pipe has been laid and the joints made, pit-run
sandy gravel or field sand shall be placed from the bottom of the pipe to
a point slightly above the spring line of the pipe such that the material
shall be at least as high as the spring line of the pipe after the gravel
has been compacted. The gravel shall be placed uniformly on both sides of
the pipe in order to prevent disturbance of the pipe and if necessary,
blocking, shall be placed against the sides of the trench to prevent dis-
placement of the pipe. The gravel shall be worked under the haunches of
the pipe during the time the gravel is being placed.
3. The pit-run sandy gravel or field sand shall then be jetted
as outlined above.
4. The remainder of the trench shall then be backfilled with
excavated material or an approved backfill material. The excavated material
from rock or shale cut shall not be used for backfill, and other materials
shall be provided by the Contractor in lieu of these materials. The back-
fill shall be placed in layers not exceeding five (5) feet in thickness
loose, and each layer shall be thoroughly jetted with water. No rock shall
be used in the backfill within two (2) feet of the pipe and no rock larger
than six (6) inches in diameter in its largest dimension shall be used in
any backfill.
After the earth backfill has dried out reasonably well, then the
entire backfill, including the pit-run gravel, shall be jetted a final time.
Jetting shall-be as previously outlined. Surplus trench excavation shall be
deposited on the property in the immediate vicinity if requested by the prop-
erty owners and/or otherwise disposed of in a manner satisfactory to the
Engineer.

street between two intersecting streets or owns any adjacent, sizeable,
tract of land which may, at some future date, become subject to development
of any type. Any new construction requiring the extension of water, sewer,
and/or storm drainage mains, except construction of a one or two family
residence, requires a community facilities contract.
b. Requests for Preparation of Contracts: Requests for the preparation
of proposed agreement should be made by letter to the city together with
four copies of a plat clearly designating the proposed area to be developed.
The letter should contain any specific or unusual requests of the developer.
The city shall prepare the agreements and submit copies to the developer and
City Council.
C. Approval of Agreement: After the agreement has been signed by the
developer and returned to the city, it shall be submitted to the City Council
for review. Any special provisions or deviations from established policies
included in the agreement shall specifically be brought to the attention of
the City Council.
8.1d OWNERSHIP AND MAINTENANCE: All community facilities installed in
connection with any evelopment project shall be and shall remain the property
of the city, and after acceptance by the city, and termination of one year
maintenance bond, shall be operated by the city.

8.le PERFORMANCE BONDS OR CASH DEPOSIT: Performance bonds, or a cash
10 deposit in lieu of the performance bonds are required for streets, storm
drains, water and sewer facilities and must be submitted with an execution
construction contract for installation of community facilities by the developer.
The bonds should be standard performance bonds as provided by licensed surety
company on forms provided by that surety company. The bonds or deposit should
be in the following amount:
a. 100 percent of the total storm drain cost;
b. 100 percent of the total street improvement cost;
C. 100 percent of the total water and sewer facilities cost;
d. In all three cases specified above, such amounts will include
anticipated construction cost.
8.1f ENGINEERING AND INSPECTION: The developer shall prepare or have
prepared by an approved professional engineering firm, final and complete
plans at his own expense. Such plans shall be prepared in accordance with
established city design criteria, rules, and regulations and shall be approved
by the City Engineer prior to award of any bids by the developer.
An inspection and supervision fee of four percent (40) of the total
anticipated construction cost is charged by the city, such amount being
deposited with the city prior to the execution of the developer's agreement
by the City Council.
The developer or his contractor will be responsible for the layout of
the work.
8.lg AWARD OF BIDS WHEN PUBLIC FUNDS INVOLVED: Whenever any city financial
participation is involved in any development projects, the developer will properly
and publicly advertise and receive a minimum of three competitive bids for con-
struction projects and a city employee will attend such bid opening and receive
copies of all such bids and bid tabulations.
In the case of border streets being improved on the assessment basis, the
city will award the contract.
8.1h TIME LIMITS OF CONTRACT: The life-of all developer's agreement shall
be five years.
a. Any off-site facility reimbursements will not be made for facilities
not installed in that period of time.
b. Any of the facilities or reimbursements to be performed by the developer
not completed in that period of time may be completed by the city at the developer's
expense. At the option of the City Council opinion, the installation of such
facilities are critical to the growth of the city.

C. No refunds due the developer will be made by the city until all
provisions of the contract are fulfilled by the developer.
8.1i TRANSFER OR ASSIGNMENT OF AGREEMENT: This agreement, any part
thereof, or any interest herein shall not be assigned by developer without
written consent of the city.
8.lj PARTIAL TRACT DEVELOPMENT: Partial development will be permitted
if an analysis of a general development plan required by the Subdivision Rules
and Regulations reveals that partial development and assurances of only partial
installation of water, sewer, street, and storm drainage facilities will not
be detrimental to the city.
In the event an individual or firm considered a developer under the terms
of this ordinance, sells or transfers ownership on property properly platted
and filed with the County Courthouse at the effective date of this policy,
the new owner shall establish proper assurances of the pro rata share of the
cost of installing necessary community facilities prior to awarding a building
permit on that property.
8.2 POLICY FOR STORM DRAINAGE INSTALLATIONS
8.2a PRELIMINARY DRAINAGE STUDY: In all developments, the developer may
be required to prove e, at his expense, a preliminary drainage study of the
area to be developed. This study shall be submitted prior to approval of the
subdivision by the Planning and Zoning Commission, or any time thereafter, as
requested by the City Engineer. The drainage study shall be prepared by a
professional engineer registered in the State of Texas and experienced in
municipal drainage work who is approved by the City Engineer. The study shall
include a contour map of the area, a drainage map showing the contributing
drainage areas, and/or water shed if a facility is recommended, design cal-
culations showing a preliminary sizing of the drainage facilities. This
study will be used for information purposes and will not be binding upon the
City Engineer in determining the required drainage facilities.
8.2b RESIDENTIAL "BUILT-UP AREAS": The city shall bear the cost of
drainage facilities in residential "built-up areas" where the drainage condi-
tions, overall development, or improvement projects (New Street Paving) justify
the installation of drainage facilities. Such financing of drainage facilities
in these areas shall be limited to the availability of city funds and subject
to the following exceptions:
a. Segment of storm drain systems, required to serve new construction
or serve solely the conveniences of an individual property owner, shall be
installed on the basis of the owner furnishing the necessary pipe and the
city making installation with city forces. This arrangement shall be limited
to the availability of city owned equipment.
10
61
I
b. Drainage facilities for assessment paving projects shall be at
city expense, except portions of systems which extend out of the street
right-of-way into new developments shall be financed in accordance with
the following paragraph 8.2c.
8.2c COMMERCIAL AND INDUSTRIAL PROPERTIES OR NEW RESIDENTIAL DEVELOPMENTS:
The developer shall be responsible for all drainage improvements in his sub-
division. This includes inlets, storm sewers, etc. The same policy also
applies to bridges and culverts crossing the street in the subdivision.
a. The developer shall dedicate at his expense a right-of-way of
sufficient width to construct and maintain the drainage system as installed.
b. The developer, at his expense, shall install a drainage system in
accordance with the plans prepared by a licensed Civil Engineer and approved
by the City of Southlake, with the developer paying 100% of all construction
costs.
C. The street crossing (bridges and culverts) will be constructed with
the developer paying 100% of the construction cost.
d. Any additional storm drain pipe, inlets, manholes, etc., needed to
provide for a complete drainage system will be provided for by the developer.
Plans will be accomplished by a licensed Civil Engineer.
e. No storm sewer will be required if streets will handle a 5-year
10
flood running full to top of an 8" curb. This 5-year flood data will be
calculated by Storm Drainage Criteria for the City of Southlake, Texas.
Where calculations show that water will run in streets above the top of the
curbs on a S-year frequency, all excess water shall be carried off by use of
adequate storm drainage structures or ditches.
f. Where route of drainage falls within a street right-of-way, storm
drainage will be carried in a pipe of adequate size. Necessary appurtenant
structures will also be required, such as inlets and headwalls.
g. Where drainage route does not occur in a street, drainage will be
carried off as follows:
1) Completely enclosed pipe (up to and including 48" size) based
on Criteria Calculations, or
2) Concrete lined trench, up to and including the equivalent
hydraulic capacity of an 84-inch diameter pipe, or
3) If hydraulic capacities are greater than an 84-inch diameter
pipe, unlined ditches may be constructed. These ditches will have at least
one 10-foot easement on one side for maintenance. These ditches will have a
maximum side slope of five (5) horizontal to one (1) foot vertical. Pipe or
lined ditches may be used instead of open ditches if desired by the developer
for ditches of sizes above the 84-inch pipe equivalent.
62
8.2d COMMERCIAL AND INDUSTRIAL PROPERTY: The developer will pay 100% of
the total construction, engineering, inspection costs of all drainage improve-
ments required for commercial and industrial property, regardless of location
or required size.
8.2e ENGINEERING AND SUPERVISION:
a. All storm drain installations shall be in accordance with design
criteria adopted by the City.
b. Plans shall be prepared by a licensed Civil Engineer using design
criteria established by the City.
C. In all developments, the developer will be required to provide, at
his expense, a preliminary drainage study of the area to be developed. This
study shall be submitted prior to approval of the subdivision by the City
Planning and Zoning Commission, or any time thereafter, as requested by the
City of Southlake, Texas. The drainage study shall be prepared by a
professional engineer registered in the State of Texas, and experienced in
municipal drainage work and will be approved by the City of Southlake, Texas.
The study shall include a contour map of the area, a drainage map showing the
contributing drainage areas, and if a facility is recommended, design calcu-
lations showing a preliminary sizing of the drainage facilities. This study
will be used for information purposes and will not be binding upon the City
of Southlake, Texas, in determining the required drainage facilities.
d. Installation of storm drain facilities will be accomplished by the
developer.
e. Inspection of construction will be made by an Engineer designated
by the City. This inspection will not include layout of work or measurement
for pay purposes.
f. Determination of storm drain facilities necessary and construction
requirements shall be the responsibility of the City. Where there is a
question as to the justification or size of facilities required, doubt will
be resolved in favor of additional drainage capacity.
8.2f OWNERSHIP AND MAINTENANCE: All storm drains installed and accepted
in connection with any development project shall be and shall remain the prop-
erty of the City of Southlake, Texas.
8.3 POLICY FOR STREET INSTALLATIONS
Standard residential pavement, including concrete valleys and subdrains
as required, shall be constructed on the street in accordance with standard
design specifications. Pavement suitable for thoroughfares shall be constructed
on such streets as deemed necessary by the City Engineer due to anticipated
traffic.
to
63
The Contractor shall secure the proper permits from the City before
any work is commenced.
The paving contractor shall furnish to the city, before beginning the
paving operations, a maintenance bond to cover the paving for a one year
period after acceptance of the paving by the city.
8.3a STREET CONSTRUCTION IN BUILT-UP PROPERTY AREAS
a. New Residential Street Construction: The assessment for each abutting
front foot of property shall be based on the following estimates of cost for
residential streets (30' width) including engineering and administration:
Percent of Street Cost per
Construction Cost Linear Foot
Excavation 15% $ 4.27
Curb and Gutter 23% 6.56
Paving 62% 17.67
Total Cost 100% $28.50
1) The assessment for each abutting front foot of privately owned
residential property shall be based on a one-third cost sharing basis by the
property owner on each side of the street. Based on the above estimates of
cost, the residential assessment shall amount to $9.50 per linear foot.
2) The assessment for each abutting front foot of non-profit
property shall be $9.50 per linear front foot, as established above for
privately owned residential property.
3) The assessment for each abutting front foot of apartment
property shall be actual cost, this figure being based on a one-half cost
sharing basis by the property owner on each side of the street.
4) The assessment for each abutting front foot of privately owned
commercial property shall be actual cost, this figure being based on a one-
half cost sharing basis by the property owner on each side of the street.
5) When residential or non-profit property shall constitute a
side lot" with relation to the section of the street being improved, assess-
ments will be applied at two-thirds of the normal rate from the front of the
property to the rear.
6) The maximum rate per property foot which will be assessed
against residential and non-profit property which abuts the street being
improved at the back of the lot shall be one-half the residential rate. If
the property is of such a size that it can be replatted to form a lot or lots
that will front on the street being improved, this consideration shall not
apply unless the improvements are located on the lot in such a way as to make
replatting impossible.
X
64
The assessment against irregularly shaped lots except side and
back lots shall be determined as follows:
a) Depth: (lots with average depth of less than 100 feet.)
The rate to be assessed on such lots, regardless of zoning, shall be adjusted
by the formula:
Adjusted Rate = Average Depth X Normal Rate
100
b) Slant: (Lots fronting at slant.) The footage to be
assessed on such lots, regardless of zoning, shall be the perpendicular dis-
tance between the two sides of the lot, but shall never be less than one-half
of the actual frontage on the street.
c) Converging: (Lots growing more narrow toward the rear of
the lot.) The footage to be assessed on such lots, regardless of zoning,
shall be the effective lot width which is the distance between the sides of
the lots measured at points 50 feet from the front of the lot. If the total
depth of the lot is less than 100 feet, the effective lot width shall be
measured across the lot at a point midway between the front and rear.
b. New Commercial and Thoroughfare Street Construction
1) The assessment for each abutting front foot of privately owned
residential and non-profit property shall, in all circumstances, be the same
as that specified in Section 8.3a a. above for residential street construction.
2) The assessment for each abutting front foot of privately owned
commercial property shall be computed as follows:
a) Actual bid price for curb and gutter
surface.
b) Actual bid price for pavement, including both base and
c) Actual bid price for excavation, if not included in bid
prices for curb and gutter and pavement, for the thickness of curb and gutter
and pavement.
d) An additional figure will be added to the cost specified
in items (a), (b) and (c) immediately above to include all engineering costs
in the assessment rate.
3) The assessment for each abutting front foot of privately owned
apartment property shall be computed as shown in Section 8.3a b. (2) above.
4) In the case of privately owned commercial and apartment lots,
side lot" and "back lot" credits will not apply and the normal commercial
and apartment assessment rates will be applied.
O
1
65
i ~
5) The assessment against irregularly shaped lots shall be
determined as specified in Section 8.3a a. (6) above.
C. Street Assessment - General
1) Property of zonings other than residential, but containing an
owner-occupied residence, shall be assessed at a rate equal to the residential
rate, plus one-half the difference in the residential rate and commercial or
apartment rate.
2) Property of residential zoning, but containing anon-conforming
usage other than residential, shall be assessed as commercial property.
3) Individual consideration shall be given to property which does
not have access to all or any part of the street being improved, with such
cases to be referred to the City Council for any special action that seems
justified regarding deviation from standard policies.
4) In those cases where the property owner has, in the past, paid
for excavation, curb and gutter, or paving, credits will be given in accord-
ance with the following:
a) The current value of the property owner share of the
replacement cost of curb and gutter;
b) The current remaining value of the property owners share
40 of existing paving, such value to be determined by reducing the replacement
cost of such flexible paving by 4.25% of such replacement cost for each year
said paving shall have been in existence.
5) Property owners shall pay the entire increased cost on streets
paved with a greater width than required by the city.
6) Widening for traffic channelization purposes beyond the normal
roadway width on the entire project shall not be assessed.
d. Priorities for Street Assessment Projects: Street improvement pro-
jects will be undertaken only by direct City Council order; however, the
priority of street improvement projects on the assessment basis is established
with those projects meeting the criteria as specified in the highest priorities
being worked as street assessment projects prior to those falling in the lower
priorities as established.
1) The need and importance of any given street project to the
overall growth and development of the city as recommended by the Planning and
Zoning Commission and established by the City Council;
2) The obligation of the city to meet past commitments for improving
streets on the assessment basis as established herein and as evidenced by the
passage of past street assessment ordinances for which improvements have not
been installed;
EO
66
3) A properly executed petition signed by property owners repre-
senting a minimum of 50 percent of the front footage in a given unit, con-
sisting of a minimum of one city block;
4) A properly executed petition signed by property owners repre-
senting a minimum of 33 percent of the front footage in a given unit and
representing a minimum of 50 percent of the owner occupied properties in a
given unit, consisting of a minimum of one city block.
5) The date petitions are officially filed at City Hall will be
considered in establishing the order of street assessment projects within
a given priority as specified in Items (3) and (4) immediately above.
e. Methods of Payment for Assessment Work: Paving assessments are
billed and collected by the City as a separate operation. Paving assessments
are not due until the street is paved and accepted by the City Council. Three
optional methods of payment are available:
1) The total amount may be paid in a lump sum cash payment,
without interest, if payment is made within 30 days of acceptance of the
project by the City Council.
2) The assessment may be divided into five (5) equal annual payments
over a four-year period, with the first payment due within 30 days of acceptance
by the City Council, at the highest legal interest rate at the time of the assess-
ment. The property owner will be asked to execute a mechanics lien in favor of
the city in this regard.
8.3b STREET CONSTRUCTION FOR DEVELOPERS
a. Border Streets: Border streets may be improved by the developer as
provided above, or may be improved on the assessment basis as required by the
City Council or at the request of the developer.
If a border street is improved on the assessment basis, the standard
residential credits will not be allowed the property in the development,
nor will they be given to the property on the opposite side of the street
unless it is built-up and under multiple ownership. The developer shall be
required to pay to the city, prior to the benefit hearing on such paving, the
amount of the assessment against the area which is included in the developer's
contract. If the border street is paved to coincide with the developer's en-
tire ownership and exceeds the limits of the area currently included in the
developer's contract, the developer shall be permitted to pay the assessment
against the area not included in the developer's contract over a four-year
period at the highest legal interest rate at the time of the assessment.
When such property is included in subsequent developer's contracts, the de-
veloper shall then pay to the city the total outstanding balance of the assess-
ment against such property or any portion thereof, at the time the developer
signs the developer's contract for such property or any portion thereof.
i~
67
If it is determined by the City Council that the border street need not
40 be improved at the time of development, the developer will be required to
pay his assessment amount either by direct payment to the City when first
phase development is begun or by placing funds in escrow payable to the City,
his assessment amount calculated at the estimated current construction cost
of the improvement. If the City has not begun construction of the street
within five (5) years of initiation of the development the full escrow amount
including the accrued interest will be returned.
b. Streets Within a Development: The developer will pay the entire
cost of streets within a given development or on his ownership.
8.4 POLICY FOR SIDEWALK INSTALLATION
8.4a In general, sidewalks shall be required on all streets and shall
be constructed at the same time as the street construction. The only allowed
variances from this policy shall be in conformance with Section 9 (c) govern-
ing variances.
8.4b All costs for sidewalk installation shall be borne by the developer
or property owner in the case of assessment paving of a street. If a street
is constructed prior to the development of adjacent properties, the City Council
may at its discretion defer sidewalk construction until the property develops
at which time the developer will cause to have the sidewalk installed as a
part of his development.
SECTION 9 - VARIANCES AND MODIFICATIONS TO STANDARDS
The City Council may, at its discretion, allow the following variances
and modifications to these published standards as follows:
a. In certain low-density developments where a rural type development
is proposed, the standard residential street section may be modified to omit
the concrete curb and gutter requirements to allow for county road type con-
struction utilizing raodside ditches for drainage. This type construction
will require 60 feet of right-of-way. Flush concrete header curbs will be
required to replace the standard curb and gutter section. The pavement
thickness section and effective roadway paving width shall remain the same.
b. Pavement thickness standards may be modified where a design analysis
made by a registered professional engineer and recommended by the City Engineer
indicates that road materials found on the site can be utilized and still pro-
duce a pavement section equal to or better than standards established in Sec-
tion 4.8 of this ordinance.
C. Variances to City policy concerning the requirement of sidewalk
installation in all developments may be granted by the City Council when one
or more of the following conditions are present:
0
68
I
1) Residential developments containing a net dwelling unit density
C) of one dwelling unit or less per net residential acre (exclusive of streets and
community facilities), except for those developments abutting a Major or
Secondary Thoroughfare street (as shown in the City's Comprehensive Plan).
2) Cul-de-sac streets serving single family detached dwellings
in which the length of said street does not exceed one hundred (100) feet
in length.
3) Other certain types of low density developments where the dwelling
unit density served by said street (except for Major and Secondary Thoroughfare
Streets) is sufficiently low to where the installation of sidewalks would not
materially aid in safeguarding pedestrian circulation from vehicular circula-
tion.
4) Certain types of Commercial or Industrial developments located
adjacent to State or federal numbered highways where primary access to the
site is dependent upon motor vehicles rather than pedestrians, and where such
land use is not adjacent to a pedestrian school route.
S) Certain types of Commercial or Industrial developments such as
wholesaling, warehousing or storage or other non-pedestrian oriented access,
when within a planned development district.
