The city has in the past experienced significant soil erosion
and sedimentation problems. Large quantities of earth have been displaced
from private property onto drainage easements, storm drains and other
public places, access easements, public easements and public rights-of-way.
Erosion is a dangerous activity in that it contaminates water supplies
and water resources. Excessive sedimentation clogs watercourses, drainage
easements and storm drains, and causes flooding which results in substantial
damage to public and private lands. These problems result in a serious
threat to the health, safety and general welfare of the community.
(Ordinance O-08-11 adopted 7/18/11)
This article sets forth the minimum performance standard necessary
to protect against erosion and sedimentation problems within the city
and to establish the various public and private responsibilities for
providing this protection. It is the intent of this article to set
forth performance standards which all erosion and sedimentation controls
must, at a minimum, meet. It shall be the duty and responsibility
of all persons, firms or corporations to which this article applies,
to design and implement erosion and sedimentation control measures
which meet the performance standards contained in this article. Further,
it is the purpose of this article to:
(1) Protect
human life, health and property;
(2) Minimize
expenditures of public money for cleaning sediment out of streets,
sidewalks, storm drains and watercourses;
(3) Ensure
that those who expose soil to possible erosion losses are minimizing
those soil losses;
(4) Preserve
the natural beauty and aesthetics of the community;
(5) Prevent
the pollution of streams, ponds and other watercourses by sediment;
(6) Provide
for restoration of sites to reduce the negative environmental impacts
of construction activity.
(Ordinance O-08-11 adopted 7/18/11)
The provisions of this article apply to:
(1) Any
person, firm, corporation or business proposing to develop land or
improve property within the city;
(2) Any
person, firm, corporation or business currently developing land or
improving property within the city; and
(3) Any
person, firm, corporation or business who own, possesses, is in custody
of, or exercises control of, property within the city. This article
applies to individual building structures, subdivisions, excavations
and fill operations, all development and all other similar development
activities.
(Ordinance O-08-11 adopted 7/18/11)
Besides this article, the city has other ordinances, regulations,
and specifications possibly affecting erosion and sedimentation control.
In the event of a conflict between this article and any other ordinances
of the city, the most restrictive ordinance shall govern.
(Ordinance O-08-11 adopted 7/18/11)
All properties (lands) within the city are subject to this article.
(Ordinance O-08-11 adopted 7/18/11)
It shall be unlawful for any person, firm or corporation which
owns, possesses, is in custody of or exercises control of property
to permit a public erosion nuisance to occur on said property. A public
erosion nuisance is an occurrence where erosion of, or sediment from,
one location causes an unsafe, bothersome, or unsightly condition
on public property and public rights-of-way. An unsafe, bothersome
or unsightly condition or burden includes silt, mud or similar debris,
originating on one property but being deposited onto a second off-site
property, which is public property or a public right-of-way from which
the city may have to remove or clean up the deposit due to liability,
statutory, aesthetic, drainage or property damage concerns. Examples
include, but are not limited to:
(1) Excessive
sedimentation in storm drains, drainage easements and watercourses
caused by erosion; and
(2) Excessive
sedimentation on public streets, sidewalks, alleys, easements and
other rights-of-way caused by erosion. It is not a violation of this
article if erosion and sedimentation occurs upon private property
and is deposited upon private property. Only erosion and sedimentation
which impacts upon public property and public rights-of-way are governed
by this article.
(Ordinance O-08-11 adopted 7/18/11)
It shall be the duty of the appointed city manager or his designee
to give forty-eight hours (48 hours) notice, in writing, to the owner
or agent in charge of any premises believed to be in violation of
this article, to correct the public erosion nuisance and to clean
up and remove the offending and burdensome sedimentation. A notice
of less than forty-eight (48) hours may be given in the event that
the city manager decides, in his/her judgment, that the situation
believed to be in violation of this article poses a substantial and
immediate threat to public health, safety, and welfare.
(Ordinance O-08-11 adopted 7/18/11)
The city council may grant a written variance from the provisions
of this article if strict adherence to requirements will result in
unnecessary hardship and not fulfill the intent of this article. The
owner shall submit a written request for a variance to the city. The
request shall state the specific variances sought and reasons for
requesting the variance. The city shall not grant a variance unless
and until sufficient specific reasons justifying the variance are
provided by the owner.
(Ordinance O-08-11 adopted 7/18/11)
In the event that the owner of any lot, tract, parcel of land,
or a portion thereof situated within the corporate limits of the city
shall fail to comply with this article, then the city manager, or
his designee, shall notify such owner by letter, addressed to him
at the address shown on the last approved tax rolls of the city or
at any residence or business structure located on subject property
or at the last known address. The mailing of notice in accordance
with any of the above shall satisfy this section. In the alternative,
the city may notify the owner by publication in the city’s official
newspaper on one (1) occasion. At the expiration of ten (10) days
after notification or publication, the city may enter upon such premises
and may do such work as is necessary, or cause the same to be done,
in order that the premises may comply with the requirements set forth
within this article. A statement of the cost incurred by the city
to abate such condition shall be mailed to the owner of said premises,
which statement shall be paid within thirty (30) days of the date
of the mailing thereof. In the event that said statement has not been
paid within such period, the city manager or the appointed city manager
may file a statement with the Dallas County Clerk of the expenses
incurred to abate such condition on said premises, and the city shall
have a privileged lien on any lot, tract or parcel of land upon which
such expense is incurred, together with ten (10) percent on the delinquent
amount from the date such payment is due. For any such expenditure
and interest, as aforesaid, suit may be instituted and recovery and
foreclosure had in the name of the city and the statement so made,
as aforesaid, or a copy thereof shall be prima facie proof of the
amount expended in any such work performed by the city. The city manager
or his/her designee shall file a statement of expenses incurred, giving
the amount of such expenses, the date on which said work was done
or improvements made, with the county clerk; and the city shall have
a privileged lien on such lots or real estate upon which said work
was done or improvements made to secure the expenditures so made,
in accordance with the provisions of subchapter “A” of
chapter 342 of UTCA Health and Safety Code, which lien shall be second
only to tax liens and liens for street improvements; and said amount
shall bear ten (10) percent interest from the date said statement
was filed. Further, for any such expenditures and interests as aforesaid,
suit may be instituted and recovery and foreclosure of said lien may
be had in the name of the city; and the statement of expenses so made,
as aforesaid, or a certified copy thereof, shall be prima facie proof
of the amount expended for such work or improvements.
(Ordinance O-08-11 adopted 7/18/11)
The city manager or his/her designee is hereby appointed to
administer and implement this article. The duties of the city manager
or his/her designee shall include, but not be limited to:
(1) Inspecting
sites to determine compliance with this article;
(2) Determining
if sureties shall be exercised. If so, the city manager shall arrange
for the work to be done, and if not, the city manager shall return
the sureties to the applicant; and
(3) Determining
if a “stop-work order” shall be issued and, if so, when
the “stop-work order” shall be removed from the project
or construction, and work allowed to commence or recommence.
(Ordinance O-08-11 adopted 7/18/11)
The owner, builder, developer, tenant, or any other person,
firm, or corporation who owns, possesses, is in custody of, or exercises
control of, property shall be responsible for any silt, mud, or sands
transported from the property by drainage. The intent of this article
is that owners, builders, and developers make provisions for preventing
erosion and sedimentation problems at such time as their property
is proposed for development, use, or modification, and to continue
such preventive measures during the actual construction and development
of the property. Additionally, all persons, firms, or corporations
who, after construction and development, own, posses, are in custody
of, or exercise control of, the property are responsible for preventing
the erosion and sedimentation problems addressed by this article.
(Ordinance O-08-11 adopted 7/18/11)
In addition to those requirements for subdivisions found in
this code, all applicants for subdivision of land shall submit to
the city manager an erosion and sedimentation control plan for approval
prior to the commencement of construction. The erosion and sedimentation
control plan shall be included in the engineering construction plans.
(Ordinance O-08-11 adopted 7/18/11)
The objective of the erosion and sedimentation control plan
is to prevent public erosion nuisances. The prevention of public erosion
nuisances can be promoted, in part, by the following goals:
(1) Reduce
sedimentation in streams, creeks, lakes, waterways, storm drains,
etc.
(2) Protect
the quality of the water in the city.
(3) Provide,
protect, and preserve wildlife habitat.
(4) Provide
for restoration of sites to reduce the negative environmental impacts
of construction activity.
(Ordinance O-08-11 adopted 7/18/11)
In order to implement the objectives stated above, the following
design considerations are necessary:
(1) Limit
the size of disturbed areas to the greatest extent possible.
(2) Stabilize
any disturbed area as soon as possible.
(3) For
construction activities in waterways, the following additional requirements
must be met.
(A) At the end of each working day the contractor shall remove all loose
excavated material from the channel.
(B) No construction or fill materials can be stored within the limits
of the channel. All equipment and materials storage and staging areas
must have erosion controls.
(C) Rock berms or sand bag berms shall be used to entrap sediment.
(D) Flooding potential should be considered when locating the control
measures.
(4) Controls
are required to intercept silt from all disturbed areas.
(5) Keep
the velocities of stormwater runoff below the erosive level.
(6) Protect
street areas and areas disturbed by development activity from upstream
runoff.
(7) Capture
and filter/drain stormwater runoff.
(8) Minimize
the extent of sediment leaving the project site.
(9) Reduce
flooding hazards and silt removal cost associated with excessive sediment
accumulation in storm drains and waterways.
(10) Reduce the concentration of stormwater runoff and promote street
flow to greatest extent possible.
(11) Revegetate all disturbed areas with a rapid, vigorous growth of long-term
vegetation composed of a mixture of grasses, forbs and woody plants.
(12) Provide sedimentation and/or filtration pond to maintain and improve
water quality.
(13) Erosion control plans should be phased to accommodate for changes
in drainage patterns that occur during development.
(14) Reduce the silt leaving a construction site on the wheels of construction
vehicles by providing vehicle washing areas and/or established construction
entrances and exits.
(15) Preserve and protect existing vegetation to the greatest extent possible.
(16) Planning should consider the natural topography and soil condition
in an attempt to limit the erosion potential.
(17) Design erosion/sedimentation controls to harmonize with natural character
of the lands.
(18) When storm drain inlets must be protected, a perimeter filtration
dike shall be used (triangular filtration dike or hay bale dike).
The above listed considerations are illustrative only, and are not
to be considered an exhaustive list of criteria effective erosion,
and sedimentation plan should address in order to prevent a public
erosion nuisance. It shall be the sole responsibility of the applicant
to prepare and submit an erosion and sedimentation control plan which
meets the requirements of the city and this article. The plan shall
include sufficient information to evaluate the environmental characteristics
of the affected areas, the potential impacts of the proposed grading
on water resources, and the effectiveness and acceptability of measures
proposed to minimize soil erosion and off-site sedimentation. The
applicant shall certify on the drawings that all clearing, grading,
drainage, construction, and development shall be conducted in strict
accordance with the plan.
(Ordinance O-08-11 adopted 7/18/11)
It is to be understood that the approval of an erosion and sedimentation
control plan by the city does not constitute recognition by the city
that the erosion and sedimentation control plan will prevent any,
or all, public erosion nuisances. By approval of the erosion and sedimentation
control plan, the city does not warrant that the erosion and sedimentation
control plan will be sufficient to prevent a public erosion nuisance,
and the city waives no rights to pursue any legal remedies, both under
this article, and all other applicable ordinances and laws. If for
any reason, after an erosion and sedimentation control plan is approved
by the engineering department, a public erosion nuisance occurs on
property addressed by said erosion and sedimentation control plan,
the approval of said erosion and sedimentation control plan shall
not be a defense or bar to prosecution under this article.
(Ordinance O-08-11 adopted 7/18/11)
The planning considerations given in this article for erosion
controls rely on a degree of erosion and sedimentation control and
flood protection that is considered reasonable for regulatory purposes
and that is based on scientific, engineering, and economic considerations.
This article does not imply that erosion and sedimentation controls
will survive inundation by runoff from storms or that land below such
controls will be free from flooding or flood damages. This article
shall not create liability on the part of the city, or any officer
or employee thereof, for any flood damages, or erosion or sedimentation
damages, whether to persons or property, that result from reliance
on this article or any administrative decision lawfully made thereunder.
(Ordinance O-08-11 adopted 7/18/11)
The applicant shall provide a surety in the form of cash, certificate
of deposit, surety bond, or irrevocable letter of credit acceptable
to the city to insure that vegetative cover and other permanent erosion
control measures are installed, maintained, and functioning properly
up to a two (2) year period from the date of final acceptance of the
dedicated streets and/or utilities by the city. This surety shall
be given to the city before the final acceptance of the streets and/or
utilities. This surety shall be in the amount estimated by the developer,
which is one hundred percent (100%) of the cost of constructing and
maintaining the permanent erosion controls for a two (2) year period.
However, such estimate is subject to review by the city manager and
may be rejected, and the surety not accepted, if the city manager
deems the estimate not to be a reasonable approximation of the costs
of constructing and maintaining the erosion controls. Should the vegetative
cover die or become sparse or the erosion controls fail to be maintained
or are not functioning during this two-year period, the city may notify
applicant in writing. The applicant has ten (10) days after being
notified to begin correcting the problems. If no corrections are started,
the city may make the necessary repairs by exercising the surety or
billing the applicant. If at the end of the two-year period the vegetative
cover is still not established or is sparse, or the erosion controls
are not functioning, the city may exercise the surety and have the
erosion controls installed and established. The above procedures for
ensuring that vegetation is established shall apply to all projects,
whether or not the vegetation is the long-term maintenance responsibility
of the city. Any vegetative cover which is planted and is a permanent
part of the improvement project will not be accepted by the city until
the growth has been established and maintained by the developer for
a two (2) year period from the date of final acceptance of the subdivision.
After the two-year period has elapsed, the owner of the property shall
be responsible for maintaining the erosion controls in good working
order. If any future owner modifies or disturbs the erosion controls
for the area, that owner must restore or replace the permanent erosion
controls at the conclusion of the disturbing activity.
(Ordinance O-08-11 adopted 7/18/11)
All development, improvement, and construction on any land which
is in violation of the provisions of this article may be halted and
stopped by order of the city manager. No stop-work order may be issued
until the notice provisions of this article are fully complied with
by the city and the owner or agent of the premises is given reasonable
time period to correct the public erosion nuisance and to clean up
and remove the offending and burdensome sedimentation.
(Ordinance O-08-11 adopted 7/18/11)
Any person violating any of the provisions of this article shall
be deemed guilty of a misdemeanor and upon conviction thereof shall
be fined in a sum not to exceed five hundred dollars ($500.00) and
a separate offense shall be deemed committed upon each day during
or on which violation occurs or continues.
(Ordinance O-08-11 adopted 7/18/11)
