ARTICLE III

SUBDIVISION REGULATIONS

Section 24-56.1 - PURPOSE

This section is adopted to provide recreational areas in the form of parks as a function of subdivision and site development in the City of Laredo. This section is enacted in accordance with the home rule powers of the City of Laredo, granted under the Texas Constitution, and the statutes of the State of Texas, including, but not by the way of limitation, Texas Local Government Code Chapter 212 (Vernon 1988; Vernon Supp. 1999). It is hereby declared by the City Council that recreational areas in the form of parks are necessary and in the public welfare, and that the only adequate procedure to provide for same is by integrating such a requirement into the procedure for planning and developing property or subdivisions in the City. This ordinance is applicable when the proposed development creates a new increase in density.

Therefore, the following requirements are adopted to affect the purposes stated above and shall apply to any land to be used for residential purposes.

(Ord. No. 2025-O-067, 4-22-25)

Section 24-56.2 - GENERAL REQUIREMENTS

Requirements for Parkland and Improvements shall cover both land dedications and park improvement fees for parkland for all types of residential development.

A.

Parkland Dedication and Site Approval Process.

1.

Every master plan, plat or site plan that incorporates residential development (single family, multi-family or manufactured housing) that results in an increase in net density as determined by the City of Laredo Parks Department must designate park space to be dedicated as a park unless otherwise provided for hereunder.

2.

The proposed site of the park shall be shown on the master plan and shall be labeled "proposed park."

3.

The designation on a master plan of "proposed park" shall in no way obligate the City of Laredo to accept the proposed park until such time as the park site has been approved as set forth herein and submitted and accepted by the City Council of the City of Laredo through a separate dedication instrument, the form of which shall be approved by the City Attorney of the City of Laredo.

4.

Once a master plan has been submitted to the Planning and Zoning Department, as set forth above, a copy of the master plan shall immediately be submitted to the Parks and Recreation Department of the City of Laredo.

5.

The Director of the City of Laredo Parks and Recreation Department shall review the master plan's proposed park site and formulate a written recommendation.

6.

The written recommendations of the Parks and Recreation Department Director shall, within two business days, be submitted to the Planning and Zoning Department and shall be included with the comments on the master plan, plat or site plan, to be deliberated on and approved by the City of Laredo Planning and Zoning Commission. In the event the time frame set out above cannot be met, the Director of the Parks and Recreation Department may present his/her recommendation to the Planning and Zoning Commission at their meeting and submit the written recommendation within five (5) working days after the meeting.

7.

Upon approval of the master plan and park site the Director of the Parks and Recreation Department shall submit the park site to the City Council for "Parkland Site Reliance Approval." Said submission shall include the written recommendation of, the Parks and Recreation Director and the Planning and Zoning Commission.

8.

"Parkland Site Reliance Approval" of the site or sites issued by the City Council is sufficient for the developer to rely on and to continue the development process. It shall insure acceptance of the parkland by the City in compliance with the Parkland Site Reliance Approval. The pendency of the Parkland Site Reliance Approval shall not be construed to prohibit a developer from proceeding with the platting of the first phase of the development.

9.

As part of the master plan review process, a letter of approval will be issued to the developer from the Parks Director that shall stipulate the improvements to be built on the dedication parkland (whether improvements are to be made by the developer or the City), and the timeline for park design and construction completion.

10.

In the event that a Developer makes any material and substantial change to the master plan, as determined by the Planning Director, the Developer shall be required to initiate the approval process for the park site or sites again.

11.

Upon submission of a plat or site plan to the Building Department for a multi-family development, the requirements for parkland and improvements shall be reassessed to ensure consistency with the Parkland Dedication Ordinance.

12.

Prior to acceptance of parkland, developer will provide a copy of CAD file of park boundary and contour data.

B.

Land Dedication.

1.

Whenever parkland is included in a final plat to be filed of record with the County Clerk of Webb County for development of a residential area in accordance with the subdivision regulations of the City, such plat shall show the parkland to be dedicated and shall be labeled "park land." The plat shall include a fee simple dedication of the area of land to the City for park purposes or the parkland may be conveyed as a park by separate dedication instrument as approved by the City Attorney. Dedication and Park Improvement fees shall be calculated as per Appendix A, Fees and Calculations, attached herein and incorporated and made a part of this ordinance for all purposes. The developer will have thirty-six (36) months of date of recordation of the first phase or issuance of building permit to build a park, or have eighteen (18) months to dedicate the park by either plat or metes and bounds in a separate instrument.

2.

The required land dedication of this subsection may be met by a payment of money in lieu of land when permitted or required by the other provisions of this section.

3.

Parkland for the entire approved master plan may be dedicated prior to the final approval of the first plat filed at the Park Director's discretion.

4.

For plats of initial master plan phases and site development in which the initial plat does not include parkland but is subject to dedication of parkland and the master plan is phased through multiple plats the following shall apply:

(a)

Deferment Contract.

(1)

If the subdivision is proposed in phases and proposed parkland is shown on a master plan and the first phase or plat includes less than one hundred fifty (150) residential lots or dwelling units then the applicant may plat the first phase or plat and defer the dedication of parkland; however, no further subdivision plat within the master plan or the property subject to that master plan shall be accepted or approved unless and until parkland is dedicated as per the requirements of this ordinance. In no event shall any deferral continue more than thirty-six (36) months from the date the plat is filed of record with the Webb County Clerk. They will have eighteen (18) months to dedicate the park to the City if the developer is not building the park. The developer shall reserve parkland for dedication by entering into an enforceable contract, which shall include the provisions set forth in this section, with the City and approved by the City Attorney.

(2)

No development which enjoys the deferral of the parkland dedication shall proceed to plat a subsequent phase irrespective of ownership, the transfer of ownership of the remainder of the undeveloped property subject to the original approved master plan, or the amendment of the master plan, until the provisions set forth in the preceding paragraph have been met.

(3)

If the actual number of completed dwelling units exceeds the figure upon which the original dedication was based additional dedication shall be required and shall be made by cash payment in lieu of land as calculated in this ordinance.

(4)

For multi-family development or development where parkland was neither previously dedicated nor payment made with the filing of a plat or the number of completed dwelling units, exceeds the figure upon which the original dedication was made, additional park land may be dedicated, private park land and improvements may be provided to accomplish the requirements of this ordinance (so long as the entire requirement of parkland for the multi-family development is met by the private park), or payment in lieu of land required by this section shall be made at the time of the building permit application and the funds so collected shall be used for improvements to the original park dedication.

C.

Cash Payment In Lieu of Land.

1.

A landowner or developer responsible for dedication under this section may, upon request, meet the requirements of section 24.56.2 B in whole or in part by cash payment in lieu of land, in the amount calculated pursuant to Appendix A and amended from time to time by City Council, sufficient to acquire parkland or to improve existing parks. This request is subject to the recommendation of the Director of Parks and approval by City Council. The recommendation must be based upon the following criteria:

iii.

Sidewalks abutting the park.

Any and all traffic control device installation shall comply with Chapter 19 of the City of Laredo Code of Ordinances.

D.

City Option to Require Cash In Lieu of Land.

The City may from time to time decide to purchase land for parks or own land in or near the area of actual or potential development. If the City does purchase park land or owns land, the City shall have the right to require subsequent park land dedications in the surrounding area to be in cash so long as the park has the capacity to serve the development's park requirements, meets the service area requirements of a park, the cash is used for park capital improvements or capital replacements and the land is dedicated as a park. In the event the park is fully improved to park standards and no capital replacements are anticipated within two (2) years, the cash may be used for capital improvements to the park nearest the development boundary as identified under Section 24.56.4 C, without crossing a major thoroughfare unless safe crossing is approved by the Traffic Department.

E.

Park Improvement Fee.

In addition to the land dedication there shall be a Park Improvement Fee, as may be amended from time to time by City Council, to provide improvements to the park to meet the standards for a neighborhood park, community park, metropolitan, or regional park to serve the service area in which such development is located. Park improvement fee is due prior to the time of filing the final plat or issuance of initial building permit, which also applies for commercial development if its housing, and shall be calculated as per Appendix A, Fees and Calculations, attached herein and incorporated and made part of this ordinance for all purposes.

School-Park.

Definition Summary: By combining the resources of two (2) public agencies, the school park classification allows for expanding the recreation, social and educational opportunities available to the public in an efficient and cost-effective manner.

Depending on the circumstances, school-park sites often complement other public recreation or open lands. As an example, an elementary/middle school site could also serve as a neighborhood park.

Likewise, middle or high school sports facilities could do double duty as a community park or as youth athletic fields. Depending on its size, one (1) school-park site may serve in a number of capacities, such as a neighborhood park, youth athletic fields, and a location for recreation classes. Given the inherent variability of type, size and location, determining how a school-park site is integrated into the park system will depend on case-by-case circumstances. The important outcome in the joint-use relationship is that both the school district and the park system benefit from shared use of facilities and land area.

Size Objective: The optimum size of a school-park site depends on its intended use. The size criteria established for Neighborhood Park and Community Park classifications may apply.

Service Area Objectives: Neighborhood Park and Community Park classifications criteria should be used to determine school-park functions and area served. For planning purposes, the degree to which school lands, including buildings or facilities, meet community needs depends on the specific inter-local agreements formed.

Location Objectives: The location of a school-park site will be determined by the school district based on district policy. Coordinated city and school district planning allows for sitting, acquisition and facility development to be responsive to community needs. Service areas for school-park sites will depend on the type of use and facilities provided.

Program Objectives: The criteria established for neighborhood parks and community parks should be used to determine how a school-park site is developed and programmed. Where feasible, if athletic fields are developed at a school-park site, they should be oriented toward youth rather than adult programs.

Establishing a clearly defined joint-use agreement between involved agencies is critical to making school-park relationships workable. This is particularly important with respect to acquisition, development, maintenance, liability, use, and programming of facilities issues.

The orientation of school-park projects is typically for neighborhood and community recreation services. The functions may include sports, recreation classes, passive recreation activities and other recreation programs suitable to an elementary, middle or secondary education school.

School-Parks serve the recreational needs of neighborhoods or large areas within the community. The school-park service area is generally consistent with the established population services design standard for the school.

School-parks accommodate recreation programs, sports activities and specialized recreation functions.

The preceding park classification models are provided to assist the department with a graphic definition of the size and character of each park classification used in this document. Actual design and configuration of new facilities will be influenced by property size, topography, surrounding land uses and design criteria for the specific park to be developed. The park design criteria should consider specific needs of the population within a given service area. Standards for park design should be carefully followed to ensure quality of facilities and recreation program services for each park.

Section 24-56.8 - TRAIL AND PATHWAY CLASSIFICATIONS

Pedestrians, bicyclists and users of various other non-motorized transportation modes need safe, convenient and direct routes linking neighborhoods with schools and parks. The ultimate goal is for residents of all age groups and skill levels to have the opportunity to travel on a wide variety of trails to reach destinations within and outside of the city.

The Master Park System Plan provides the framework for the establishment, growth and maintenance of a citywide trail system that will include linkages to trail systems for access to neighborhoods, schools and parks. In conjunction with the city's Transportation Plan, and various other municipal policies, the trail designations and classifications shall be included in, and are an integral part of the Master Park System Plan.

Types of Trails Standards for various types of trail, bikeway and path facilities.

Paved Class I Shared Use Paths: Are provided to accommodate non-motorized wheel and pedestrian use. These are often located within a designated greenbelt and/or utility corridor. The need to accommodate multiple users requires a width of ten (10) to fourteen (14) feet, with two-foot shoulders and a minimum ten-foot height clearance.

Class II Bike Lanes: Are associated with roadways. Class II bike lanes are defined by standards as having a minimum five (5) foot width - one (1) foot wider than AASHTO minimums.

Class Ill Bike Routes (Shared Route): Usually involve a combination of a wide curb lane (thirteen (13) to fourteen (14) feet in width) and designation as a bicycle route. Shared Use Soft Surface Trails: Are designed for a six (6) to ten-foot trail width, and are intended for predominantly recreation use.

Local Soft Surface Trails: Are intended for areas with a less intense use. Intended to preserve the natural setting in which it is located, local soft surface trails are narrower and have somewhat tighter design clearances, appropriate for pedestrian and limited mountain-bike use.

Local Paved Path: Are often narrower (four (4) to six (6) feet) than a typical Class I trail, these facilities are intended to have the same general design specifications for shoulders, grade and sight distance as other paved facilities.

Hillside Connection Trails: Are trails intended to provide pedestrian access along steep terrain. These are narrower facilities (three (3) to six (6) feet) with gravel or wood mulch surfaces. Due to steeper grades, these paths may not be suitable for persons with disabilities or for all types of bicycles.

Neighborhood Paths: Are intended for locations alongside roadways. They may be either a paved or soft-surface facility. Generally, not intended for bicycle use, these facilities should have at least a 5-foot lateral separation from the roadway, although more is much preferred.

A.

Any land dedicated to the City under this section must be suitable for park and recreation uses.

B.

Prior to the dedication of land, the Developer/Owner shall make full disclosure of the presence of any hazardous substances and/or underground storage tanks (UST's) of which the Developer has any knowledge. The City, at its discretion, may proceed to conduct such initial environmental test and surveys on the land, as it may deem appropriate, and the Developer shall grant to the City and its agents and/or employees such reasonable access to the land as is necessary to conduct such surveys and tests. In the event the City elects to send its agents and/or employees onto the Developer's land it shall provide for hold harmless, indemnification and liability insurance as necessary to protect the Developer.

C.

If the results of such surveys and tests indicate a reasonable possibility of environmental contamination or the presence of UST's the City may require further surveys and tests be performed at the Developer's expense as the City may deem necessary prior to its acceptance of the dedication, or in the alternative, the Developer may or the City may require that the Developer identify alternative property or pay cash in lieu of such parkland dedication.

D.

The park site shall be free of trash and debris. At the option of the City, the land shall be left in its natural condition or cleared.

Appendix A "Parkland Dedication Fee Methodology" can be modified by City Council ordinance.

Appendix A
PARKLAND DEDICATION FEE METHODOLOGY

I.

Current Desired Level of Service.

Two (2) Acres per one thousand (1,000) Population.

II.

Land Requirements.

2022 data from U.S. CENSUS Figures—Total Population—257,602.

3.2 Person per Household (PPH) for Single-Family and 2.87 PPH for Multi-Family based on census information for owner and renter occupied units. The overall average from the Census is 3.04 PPH (dwelling unit).

• SINGLE-FAMILY two (2) acres per one thousand (1,000) people; MULTI-FAMILY one (1) acre per one thousand (1,000) people.

One-thousand (1,000) people/3.04 PPH (based on decennial census) = three hundred twenty-nine (329).

Dwelling units/residential lots or two (2) acre per three hundred twenty-nine (329) units.

Dwelling units/multi-family lots of one (1) acre per three hundred twenty-nine (329) units.

The minimum land requirement for parkland dedication is two (2) acres per one thousand (1,000) population - for community or metropolitan parks.

III.

Park Acquisition Cost (Determines Cash Payment In lieu of Land) Fee shall be determined on a per-acre basis at fifty-five thousand dollars ($55,000.00) per acre or fraction thereof.

The fee shall be calculated by A x V = Cash Payment in Lieu of Land; where:

A is the required parkland dedication in acres, calculated to tenths of an acre.
V is the per-acre valuation based upon fifty-five thousand dollars ($55.000.00)

IV.

Park Improvement Fee.

The developer will be required to pay the City a park improvement fee for each dwelling which is a designated amount based on the density of the proposed development as identified below:

Lot DescriptionLot SizeAverage Lots Per AcreFee per DU
Multi-family n/a n/a $375.00
Extra Small lot 3,000-4,499 sq. ft. 16 lots per acre average $375.00
Small lot 4,500-5,999 sq. ft. 9 lots per acre average $666.67
Medium lot 6,000-9,999 sq. ft 6 lots per acre average $1,000.00
Large lot 10,000 sq. ft. and up 4 lots per acre average $1,500.00

 

The City may require up to 1.56 additional acres per three hundred twenty-nine (329) dwelling units (calculated on one thousand (1,000) population per two (2) acres) by reducing the park improvement fee by forty-five thousand dollars ($45,000.00) per additional acre or fraction thereof (see examples #2 and #3).

Example #1: A plat containing three hundred twenty-nine (329) dwelling units/large residential lot (one thousand (1,000) population).

Land Dedication per Section II of the Appendix = 2 acres

Park Improvement fee per Section IV of the Appendix

329 dwelling units/residential lot at $1,500.00 = $493,500.00

Example #2: A plat containing three hundred twenty-nine (329) dwelling units/medium residential lot (1,000 Population) and the City requiring one (1) additional acre.

Land Dedication per Section II of the Appendix = 2 acres

Additional Land Dedication = 1 acre

Total Land Dedication = 3 acres

Park Improvement fee per Section IV of the Appendix

329 dwelling units/residential lot at $1,000.00 = $329,000.00

Additional Land Dedication Credit l acre x $45,000.00 = $45,000.00

Net Park Improvement fee after credit = $284,000.00

Example #3: A plat containing three hundred twenty-nine (329) dwelling units/small residential lot (one thousand (1,000) population) and the City requiring 1.56 additional acres.

Land Dedication per Section II of the Appendix = 2 acres

Additional Land Dedication = 1.56 acres

Total Land Dedication = 3.56 acres

Park Improvement fee per Section IV of the Appendix

329 dwelling units/residential lot at $666.67 = $219,334.43

Additional Land Dedication Credit 1.56-acre x $45,000.00 ....= $70,200.00

Net Park Improvement fee after credit= $149,134.43

Selective clearing for health and safety purposes is allowed as determined by the Fire Chief and/or the Health Department Director.

(C)

The Final Plat and all right-of-way plans shall clearly show the extent of any vegetative buffer on the subject property.

(D)

All protected vegetative buffer areas and stream systems shall run with the land and continue in perpetuity. Protected vegetative buffer areas and stream systems may be dedicated to the public by separate instrument (which must be submitted to the City Engineer for approval and recorded in the land records) unless the protected vegetative buffer area and stream system is dedicated to the public on the face of an approved plat. If the owner of the property desires to keep the stream system and buffer private, there shall be a covenant (which must be submitted to the City Engineer for approval and recorded in the land records) restricting the use of the stream system and buffer to uses set forth herein, and the owner must ensure that the stream system and buffer shall be maintained by the owner, his heirs successors and assigns for so long as the stream system and buffer remain private.

(E)

The ESD shall inspect the buffer annually and immediately following severe storms for evidence of sediment deposition, erosion, or concentrated flow channels. Corrective actions shall be taken to ensure the integrity and functions of the vegetative buffer.

(F)

The City of Laredo will maintain all vegetative buffer and stream systems that are created pursuant to Section 24-58.3 and have been dedicated to the public.

Section 24-57.9 - INCENTIVES

(A)

If buffer widths on first and second order streams are strictly adhered to, the conservation plan requirement shall be waived.

(B)

Credit shall be given as determined by the Planning Director for the development of Linear Parks around natural drainage and wooded areas that provide potential recreational uses. Criteria for flood plain areas (based upon a hundred-year flood plain) that is dedicated as parkland, will be given credit as determined by the Planning Director by meeting the following requirements:

1.

Flood plain and natural drainage area shall generally not exceed seventy-five percent (75%) of total park site.

2.

At least fifty percent (50%) of required dedicated parkland shall have slopes in range of less than five percent (<5%), well-drained and suitable for active use.

The purposes and objectives of this Code are as follows:

1.

To protect, maintain, and enhance the public health, safety, and general welfare by establishing minimum requirements and procedures to control the adverse impacts associated with stormwater runoff. Proper management of stormwater runoff will minimize damage to public and private property, reduce the effects of development on land and stream channel erosion, assist in the attainment and maintenance of water quality standards, reduce local flooding, and maintain after development, as nearly as possible, the pre-development runoff characteristics.

2.

To prevent the discharge of contaminated stormwater runoff from development and/or redevelopment or construction sites into the Municipal Separate Storm Sewer System (MS4) and natural water within the City of Laredo and its extraterritorial jurisdiction.

3.

To facilitate compliance with state and federal water quality standards, limitations, and permits by owners and operators of development and/or redevelopment sites or construction sites within the City of Laredo.

4.

To enable the City to comply with all federal and state laws and regulations applicable to stormwater discharges.

5.

To maintain and improve the quality of surface water and groundwater within the City of Laredo by preventing the introduction of pollutants to the maximum extent practicable (MEP) using best management practices (BMPs).

6.

To establish responsibility for the reduction of harmful and damaging effects of development-generated erosion, sedimentation, stormwater runoff, and accumulation of debris on other properties and receiving waters.

7.

To minimize harm and long-term costs to the community from activities, which may adversely impact water resources.

8.

To encourage the use of Regional Stormwater Detention Facilities.

Section 24-59.1.2 - SCOPE AND JURISDICTION

The application of this Code and the provisions expressed herein shall be the minimum stormwater management requirements for development and/or redevelopment of a site within the City of Laredo and its extraterritorial jurisdiction. It shall not be deemed a limitation or repeal of any other powers granted by the State statute. In addition, if site characteristics indicate that complying with these minimum requirements will not provide adequate designs or protection for local property or residents, it is the designer's responsibility to exceed the minimum requirements as necessary. The City Engineer or his/her authorized representative shall be responsible for the coordination and enforcement of the provisions of this Code.

Section 24-59.2.6 - STORMWATER CONCEPT PLANS

The stormwater concept plan is designed to allow the City to review the proposed development/redevelopment or construction activities prior to extensive design. This allows the City to ensure that all aspects of the stormwater management code have been addressed early in the design process. Additionally, it allows the developer/engineer the opportunity to address all aspects of the design, with regard to this Code, with the City prior to extensive design and plan development.

1.

A stormwater concept plan for each development/redevelopment and construction activity shall be submitted for review by the City Engineer prior to submission of the stormwater management plan and construction plans for the entire development/redevelopment or construction activity, or any portion thereof.

2.

All preliminary plats of the development/redevelopment or construction activity shall be consistent with the stormwater concept plan required in paragraph (1) above.

3.

Upon approval of the concept plan, the applicant shall submit a final stormwater management plan (as part of the construction plans) to the City Engineer for review and approval. The City Engineer may accept and submit into the review process a stormwater concept plan if it identifies the location and type of facilities to be constructed in sufficient detail to accurately assess proposed impacts and the City Engineer determines that a stormwater management plan is not needed. If accepted under this provision, the stormwater concept plan then becomes the stormwater management plan for this development.

4.

Should any stormwater management plan involve any stormwater management facilities or land to be dedicated to public use, the same information shall also be submitted for review and approval to the department having jurisdiction over the land or other appropriate departments or agencies identified by the City Engineer for review and approval. Upon approval by all such departments and agencies this stormwater management plan shall serve as the basis for all subsequent construction.

5.

The developer and his/her engineer shall be responsible for the accuracy of the information furnished in the design of the storm drainage facilities, pertaining to both the development/redevelopment or construction site in question (on-site) and affected (off-site) properties. Permit approval, by the City of Laredo, of the design plans and specifications shall not be construed to relieve any responsibility of the developer/engineer referred to herein.

6.

All drainage easements, both on-site and off-site, shall be dedicated to the City of Laredo, with the easement called-out and appropriately identified as an easement to be dedicated to the City of Laredo for drainage purposes. Appropriate drainage easements on designated floodways (HUD-FEMA Maps) shall be properly described.

7.

Compliance with Federal Emergency Management Agency (FEMA) regulations is mandatory. All subdivisions shall conform to the "Federal Disaster Protection Act of 1973, Public Law 93-234, passed by the 93rd Congress, H.R. 8449, December 31, 1973 (the latest revision thereof).

8.

The stormwater concept plan may be reviewed, if needed, with the designer, after City Engineer review, where it will either be approved, approved with changes, or rejected.

The Appeals Board will then render a decision within fifteen (15) days after the appeal has been heard.

Each party to the appeal shall be entitled to a hearing before the Appeals Board under judicial forms of procedure, at which hearing each party shall have the right to present evidence and sworn testimony of witnesses, to cross-examine witnesses, and to cause a transcription of the proceedings to be prepared.

Should either party be dissatisfied with the decision of the Appeals Board, any appeal of said decision may be appealed to the Superior Court by writ of certiorari.

Section 24-59.3.1.2 - METHOD OF COMPUTING RUNOFF

The basis of computing runoff shall either be the rational formula, or another method deemed acceptable by the City Engineer. Runoff rates for areas greater than one hundred and thirty (130) acres shall use either a unit hydrograph methodology, or another method deemed acceptable by the City Engineer.

Where an approved study exists (i.e. FEMA, or other regulatory agency) for areas less than one hundred and thirty (130) acres, the methodology shall match that used in the study unless otherwise dictated by the City Engineer.

In all cases, wet antecedent conditions shall be assumed. Run-off rates shall be computed on the basis of ultimate development of the proposed development/redevelopment, or construction activity. Flows from off-site contributing areas draining to, and/or through, the proposed development/redevelopment or construction activity shall be based on the 25-year existing conditions. In order to determine time of concentration, times shall be calculated on the basis of an improved drainage system upstream from the area under consideration. Run-off coefficients shall be obtained from information presented in the Stormwater Management Guidance Manual.

Section 24-59.3.1.3 - OFF-SITE DRAINAGE

a.

The owner or developer of property to be developed/redeveloped shall be responsible for accepting all predevelopment storm drainage flowing onto his/her property as calculated per Section 24-59.3.1.2. Predevelopment storm drainage shall be adequately conveyed through, or around, the property. This responsibility includes all drainage directed to that property by prior development as well as drainage naturally flowing naturally through the property by reason of topography.

b.

Adequate consideration shall be given to determine how the stormwater discharge leaving the proposed development will affect downstream property. In determining downstream effects from stormwater management structures and the development/redevelopment, or construction activity on receiving streams known to having flooding or erosion problems, the City Engineer may require, at his/her reasonable discretion, that hydrologic-hydraulic engineering studies be extended downstream, to a point where the proposed development/redevelopment or construction activity represents less than ten (10) percent of the total contributing watershed.

c.

Any construction activity that requires off-site grading or encompasses an area in compliance with current EPA/NPDES stormwater permitting provisions, where stormwater runoff has been collected or concentrated, whether it be by permanent drainage systems or streets, shall not be permitted to drain onto adjacent property except in existing creeks, channels, storm sewers, or streets unless the following is provided:

(1)

Notarized letter of permission from the affected property owner;

(2)

Proper drainage easements are obtained;

(3)

If the owner is unable to acquire the necessary off-site easements, he/she shall provide the City with documentation of his/her efforts, including evidence of a reasonable offer made to the adjacent property owner. By written request for assistance, the City may assist the negotiations to acquire off-site easements. If the negotiations are unsuccessful, the request may, at the developer's option, be submitted to the City Council for consideration of acquisition through condemnation. In either case, the total cost of the acquisition and the cost of the easements shall be paid by the owner/developer; or

(4)

If the developer is unable to obtain either paragraph (1) or (2) above and chooses not to seek assistance from the City, as outlined in paragraph (3) above, he/she shall provide the City with documentation of his/her efforts. The developer will then execute a notarized letter; said letter shall be in a form approved by the City Attorney and shall provide that the developer shall agree to save and hold harmless the City of Laredo from any and all claims or suits for damage arising out of the required grading and/or concentrations of flow. The City reserves the right to require the notarized letter of permission or easement from the affected property owner prior to construction.

d.

The subdivider shall pay for the cost of all (post-development) drainage improvements or offsite downstream upgrades required for the development of his/her subdivision; these include any necessary off-site channels, or storm sewers, and acquisition of the required easements. In areas where the proposed off-site improvements are to be made within existing City right-of-way(s), an estimate of these off-site costs shall be prepared and submitted with the drainage plans.

e.

Where it is anticipated that additional runoff incident to the construction activity will overload an existing downstream drainage facility, whether natural or man-made, and result in hazardous conditions, the City Engineer may withhold approval of the activity until appropriate provisions has been made to correct the problem. Plans shall be provided which include all necessary off-site improvements including storm sewer systems, channel grading, driveway adjustments, culvert improvements, etc.

Section 24-59.3.1.4 - FINISHED FLOOR REQUIREMENTS

The first floor elevations of all residential and other structures shall be set at a minimum elevation as per the latest adopted International Residential Code.

The approved drainage system shall provide for positive overflow at all low points. The term "positive overflow" means that when the inlets do not function properly or when the design capacity of the conduit is exceeded, the excess flow can be conveyed overland along a grassed or paved course. The approved drainage system shall provide for positive overflow at all low points. Normally, this would mean along a street alley, or otherwise shall require the dedications of special drainage easements on private property.

Positive overflow sections shall provide a minimum of two (2) feet from the overflow invert adjacent to the structure and the corresponding first floor elevation of all residential and other structures.

All lots affected by positive overflow section shall be labeled and minimum finished floor elevation shall be provided on face of the subdivision plat. The Building Official shall require a finished floor National Flood Insurance Program elevation certificate in compliance with this ordinance as a prerequisite to obtain a Certificate of Occupancy.

When the drainage characteristics of a subdivision are such that a portion of the subdivision is within or adjacent to the 100-year floodplain, the City Engineer shall require that minimum finished floor elevations be shown on all lots contained within or adjacent to the 100-year floodplain. These elevations should be based on the most current flood plain management criteria. The elevations shall be shown on the plat prior to filing the plat for record. The following note shall be added to any plat upon which the City Engineer requires the establishment of minimum finished floor elevations:

"The City of Laredo reserves the right to require minimum finished floor elevations on any lot contained within this addition. The minimum elevations shown are based on the most current information available at the time the plat is filed and may be subject to change. Additional lots, other than those shown, may also be subject to minimum finished floor criteria."

Section 24-59.3.2.1 - STREETS AND CLOSED STORM SEWER SYSTEMS

Streets may be used for stormwater drainage only if the calculated stormwater flow does not exceed ten (10) feet per second. Streets and alleys shall be designed on the basis of a ten (10) year frequency storm event. Storm sewer inlets shall be built along paved streets at such intervals that the depth of flow, based upon the 10-year storm, does not exceed the top of curb. By pass flow is allowed and shall not exceed twenty-five (25) percent of the original discharge. Valley gutters shall be placed when surface drainage crosses any local street or in instances when the change in elevation between curbs returns exceeds six (6) inches. Inlets shall be located as necessary to remove the flow based on a ten (10) year storm. At any intersection, only one (1) street shall be crossed with surface drainage; and preferably this street shall be the lower classified street. When an alley intersects a street, inlets shall be placed in the alley whenever flow down that alley would cause the capacity of the intersecting street to be exceeded. Where streets are not capable of carrying stormwaters as outlined above, drainage facilities as required by these standards shall be provided.

Where closed storm sewer systems are utilized the excess discharge shall be picked up at the point where the street can no longer handle the runoff flowing curb full.

Closed storm sewer pipe size and grade shall be designed based on the following criteria:

a.

Minimum pipe size shall be twenty-four (24) inches in diameter. When circumstances do not allow for a twenty-four (24) inch diameter, the City Engineer may approve an alternate size.

b.

Minimum grade shall be such that the minimum flow velocities are not less than three (3) feet per second with the pipe flowing full under the design conditions.

c.

Allowable "n" values for design shall be as specified in the Stormwater Management Guidance Manual.

d.

Under normal conditions, pipes shall be designed assuming full flow conditions.

e.

Where conditions or design cause a pipe to flow under pressure, the hydraulic grade line shall be calculated and plotted in profile. In no case shall the hydraulic grade line be closer than one (1) foot to finished grade unless specifically authorized by the City Engineer.

f.

Pipe for storm drains shall be reinforced concrete pipe (RCP) in sizes as shown on the approved plans. All RCP shall be minimum Class III. All Class III RCPs shall have a minimum cover of not less than one (1) foot over the top of the pipe. Where added strength of pipe is needed for traffic loads over minimum cover or for excessive height of backfill, concrete pipe shall be ASTM C14 Extra Strength or ASTM C76, Class IV or Class V.

g.

City Engineer may approve alternate pipe materials (HDPE, FIBER GLASS, CMP, etc.) within the private easement, positive overflow area and within the Right-of-Way (ROW).

Section 24-59.3.2.1.1 - MANHOLES

Manholes (inlets and junction boxes) shall be provided at sewer intersections, and at a maximum of five hundred (500) feet on straight lines. Design of manholes shall conform to the City of Laredo Design Standards, as periodically amended.

Section 24-59.3.2.2 - OPEN CHANNELS

Open Channels shall be designed for subcritical flow under normal conditions. If supercritical flow exists, energy dissipation will be required to return flow to subcritical flow conditions. Open channels shall be designed to convey, at a minimum, the twenty-five (25) year frequency design storm event.

The maximum allowable velocities in constructed channels shall be based on the channel type. The following velocity chart shall be used for scour protection and to determine the maximum velocities for a given type of channel lining:

Channel Type Maximum Velocity
Grass Lined 5 fps
Concrete Lined > 5 fps

 

Other methods of bottom and slope protection may be substituted for conditions where concrete lining is required upon the approval of the City Engineer. Requests for substitution shall be accompanied by an engineering analysis of the equivalency to concrete, reasons for substitution, and an evaluation of maintenance issues.

Grass-lined channels shall include slope protection in bends, unless the radius of curvature is greater than twice the channel top width.

Open channels shall provide a minimum of one (1) foot of freeboard above design flow depth. Additional freeboard shall be provided where design conditions warrant as outlined in the Stormwater Management Guidance Manual. All channels shall have a minimum eight (8) foot bottom width to facilitate maintenance operations. Where the calculated depth of normal flow is less than the required freeboard, the City may consider reducing channel widths (valley gutter, concrete swale) or alternate configurations.

Section 24-59.3.2.3 - CULVERT AND BRIDGE CROSSINGS

All roadway culvert crossings shall be designed for a twenty-five (25) year frequency storm event. Crossings located within flood hazard zones shall be designed to ensure compliance with FEMA regulations. The hydraulic capacity of proposed culverts shall be such that headwater depth is at least one (1) foot below the minimum roadway elevation. Proposed bridges shall have a low chord elevation at least one (1) foot above the design stormwater surface elevation. All culverts located or expected to be located under paving and bridges shall be structurally designed for an HS-20 loading. Hydrologic and hydraulic calculations for all crossings must be included in the permit application to ensure compliance with this Code.

All culvert and bridge crossing(s) need to have the flood gauge installed by the developer before acceptance by the City.

Section 24-59.3.2.4 - HYDRAULIC STRUCTURES - ENERGY DISSIPATION

Where hydraulic structures are included in the design of stormwater drainage systems, energy dissipation shall be included in the structure as outlined in the Stormwater Management Guidance Manual. Hydraulic structures may include, but are not limited to: pipe outlets, spillways, drop structures, and culvert headwalls. All energy dissipators should be designed to facilitate maintenance. At the reasonable discretion of the City Engineer, the design of outlet structures in or near parks, and/or residential areas must give special consideration to aesthetics.

Section 24-59.3.2.5 - RETENTION/DETENTION FACILITIES

The following are minimum criteria for detention facilities within the City of Laredo and its extraterritorial jurisdiction. These criteria do not supersede or replace requirements established by the State of Texas for dam safety, dam construction plan review, and/or the impoundment of State Waters. Where the State of Texas requirements apply, the owner/developer and/or engineer shall provide evidence of compliance prior to final approval of the facility by the City of Laredo.

Section 24-59.3.2.5.1 - ALLOWABLE DISCHARGE - (PRE/POST ANALYSIS FOR RETENTION/DETENTION FACILITIES)

The ultimate one hundred (100) year design storm event shall be used in determining the required retention/detention volume for the development site. The discharge rate from the facility shall be such that the pre-development discharge rate from the site is not exceeded in the post-developed condition for the design storm event. The precondition discharge rate shall be calculated assuming the proposed site is in a natural state.

Upstream adjacent properties shall be considered at their existing conditions, provided that the downstream receiving stream/channel/detention pond can accept additional stormwater runoff volume without causing flooding as determined by the City Engineer.

Section 24-59.3.2.5.2 - STORAGE

The design storage shall be the volume of the design storm event hydrograph that exceeds the allowable discharge rate noted above. Basins without upstream detention areas and with drainage areas of one hundred thirty (130) acres or less may calculate storage using the Modified Rational Method as described in the Stormwater Management Guidance Manual. Basins with drainage areas greater than one hundred thirty (130) acres, or where the Modified Rational Method is not applicable, shall be designed using an approved method as described in the Stormwater Management Guidance Manual.

Section 24-59.3.2.5.3 - IMPOUNDMENT DESIGN CRITERIA

The steepest side slope permitted shall be 4:1 for a vegetated earth embankment, 2:1 for a rock dam, or as determined by a geotechnical investigation that is certified by a licensed professional engineer and approved by the City Engineer.

Earth embankments used to temporarily impound the required detention volume shall be constructed according to standard specifications for fill. These specifications should be, at a minimum, adequate for levee embankments and be based on the City of Laredo standard specifications for embankment, topsoil, sodding, and seeding.

Where permanent impoundment is to be provided a geotechnical investigation is required. Based on the geotechnical report more stringent specifications may be required.

Embankments, spillways and other appurtenances shall be designed to withstand the pressures of the impounded stormwater.

Excavated detention facilities must provide positive drainage with a minimum bottom grade of three-tenths of a percent, 0.3% (0.003/feet). A low flow concrete valley gutter shall also be provided.

Section 24-59.3.2.5.4 - FREEBOARD AND EMERGENCY SPILLWAY

The top of the embankment shall be a minimum of one (1) foot above the one hundred (100) year maximum design elevation. An emergency spillway, or overflow area, shall be provided above the maximum design elevation to ensure that the State of Texas Dam Safety overflow requirements or the one hundred (100) year frequency event, whichever is more stringent, does not overtop the embankment.

If the emergency spillway capacity is to be provided over the embankment, the spillway will be structurally designed to prevent erosion and consequent loss of structural integrity. The spillway or the dam portion of the pond shall be constructed of reinforced concrete or with concrete lining. Alternate materials may be approved by the City Engineer.

Section 24-59.3.2.5.5 - OUTFLOW STRUCTURE

Where the outflow structure conveys flow through the embankment in a conduit, the conduit shall be reinforced concrete or other material to be approved by the City Engineer designed to support the external loads with an adequate factor of safety. It shall withstand the internal hydraulic pressures without leakage under full external load or settlement. It must convey water at the designed velocity without damage to the interior surface of the conduit.

Section 24-59.3.2.5.6 - FENCE

(1)

Security fencing with a minimum height of six (6) feet shall encompass the detention and maintenance area when required, as determined by the City Engineer, due to potential safety hazards created by prolonged storage of floodwater.

(2)

Design shall be such that it does not restrict the inflow or outfall of the basin.

(3)

Adequate access for maintenance equipment shall be provided.

(4)

In basins to be used for recreation areas during dry periods, pedestrian access may be provided with the approval of the City Engineer.

Section 24-59.3.2.5.7 - FLOATABLE CONTROLS

Detention facilities shall incorporate some type of floatable controls (baffles, skimmers, etc.) to ensure that discharge of floatables from the facility is limited to the maximum extent practicable as determined by the City Engineer. As part of the ongoing detention facility maintenance, the detention facilities shall be regularly checked and any floatables removed. A maintenance regimen for the removal of floatables shall be part of the maintenance schedule submitted for permit review and approval.

Section 24-59.3.2.5.8 - MAINTENANCE ACCESS REQUIREMENTS

A minimum fifteen (15) foot wide maintenance area shall be provided to serve the detention facility. The crown (top of berm) shall have a minimum width of ten (10) feet unless used for primary maintenance of the detention facility, in which case it shall have a minimum width of fifteen (15) feet.

Access must be provided into detention basins designed for periodic desilting and debris removal. Basins with permanent storage must include dewatering facilities to provide for maintenance.

Section 24-59.3.2.5.9 - MUNICIPALITY PARTICIPATION.

When the City Engineer determines that additional storage capacity beyond that required by the applicant for on-site stormwater management is necessary in order to enhance or provide for the public health, safety and general welfare, to correct unacceptable or undesirable existing conditions or to provide protection in a more desirable fashion for future development, the City Engineer may:

(1)

Require that the applicant grant any necessary easements over, through or under the applicant's property to provide access to or drainage for such a facility;

(2)

Require that the applicant attempt to obtain from the owners of property over, through or under where the stormwater management facility is to be located, any easements necessary for the construction and maintenance of same (and failing the obtaining of such easement the City may, at its option assist in such matter by purchase, condemnation, dedication or otherwise, and subject to paragraph (3) below, with any cost incurred thereby to be paid by the City); and/or

(3)

Participate financially in the construction of such facility to the extent that such facility exceeds the required on-site stormwater management as determined by the City Engineer;

(4)

The City may assume maintenance of the facility as a stormwater management facility.

To implement this provision both the municipality and developer must be in agreement with the proposed facility that includes the additional storage capacity, and jointly develop a cost sharing plan which is agreeable to all parties.

Section 24-59.3.2.5.10 - FEE IN-LIEU-OF DETENTION

City Engineer may waive the detention requirement for small plat (less than five (5) acres) with the options of fee in-lieu-of detention when the downstream receiving stream/channel/detention pond can accept additional stormwater runoff volume without causing erosions. The calculation will be based on the combination of the construction cost and land cost of the proposed detention facility and may include the maintenance cost for two (2) years.

Section 24-59.3.2.6 - REGIONAL STORMWATER MANAGEMENT FACILITIES

For the purposes of this Code a regional stormwater management facility shall be any facility constructed on a channel or waterway whose total drainage area is greater than one hundred thirty (130) acres and serves more than one (1) development. Regional stormwater management facilities may be maintained by the City.

The design of regional stormwater management facilities shall assume that all contributing areas are fully developed in accordance with approved future land use plans. A plan of the contributing area will be submitted as part of the permitting process indicating conveyance easements through the property being developed sufficient to convey post development flows to the facility. If the proposed development is upstream of the regional stormwater management facilities, pass through conveyance systems shall be included in the design of the development.

Section 24-59.3.2.6.1 - LAKES AND DAMS

In the event that a property owner or developer desires to modify an existing pond or lake, or desires to impound stormwater by filling or constructing an above-ground dam, thereby creating a lake, pond, lagoon or basin as part of the planned development of that property — the criteria listed below shall be met before City approval of the impoundment can be given. Ponds or lakes created by excavation of a channel area without erecting a dam above natural ground elevation or instream, low water check dams are also subject to the criteria listed below with the exception of spillway capacity requirements. The City Engineer has the final authority to determine the design criteria for a proposed dam, check dam, or excavated lake. The requirements of the State of Texas must also be met for the construction of dams, lakes, and other impoundments.

The design criteria for a dam is dependent on the size and hazard classification of the dam. The size and hazard classification will be based on Chapter 12 of the Texas Water Code. The following criteria will be used to classify a dam:

1.

Size.

The classification for size is based on the height of the dam and storage capacity, whichever gives the larger size category. Height is defined as the distance between the top of the dam (minus the freeboard) and the existing streambed at the downstream toe. Storage is defined as the maximum water volume impounded at the top of the dam (minus the freeboard).

In all cases, the minimum principal spillway design capacity is the one hundred (100) year design flood. In certain cases, a dam breach analysis may be required to determine the proper classification of the structure. For all structures requiring a spillway design flood equal to the Probable Maximum Flood (PMF), a dam breach analysis is required to determine the downstream consequences of a failure. All dams designed for a Spillway Design Flood (SDF) of half (½) PMF or less shall be constructed with a minimum freeboard of two (2) feet above the SDF elevation.

 

Section 24-59.3.2.7 - RETAINING WALLS IN WATERWAYS

1.

All retaining structures/walls located within a one hundred (100) year floodplain shall be constructed of reinforced concrete or other materials approved as designed for the specific on-site conditions. Special structural designs shall be submitted with supporting calculations to the City Engineer for approval.

2.

Retaining walls shall be designed to achieve a minimum factor of safety of two (2) against overturning and one and an half (1.5) against sliding.

3.

The criteria/parameters used in considering the adequacy of the retaining wall design shall be as outlined in the Stormwater Management Guidance Manual.

4.

Any wall taller than four (4) feet in height will require a building permit and an engineer's certification that the wall is structurally sound, and built as per the plan specifications.

Section 24-59.3.3 - EASEMENTS

Property development/redevelopment that includes detention and/or drainage facilities shall dedicate easements to the City. The minimum width of easements shall be determined by the City Engineer, based on the examples set out in the Stormwater Management Guidance Manual. Final plats shall contain standard language addressing the easements and management areas, and on-ground monumentation as outlined below:

1.

Floodway easements are to be dedicated for open waterways in nonresidential areas. They will be maintained by the property owner.

2.

Drainage easements are to be dedicated for manmade drainage channels, closed storm sewer systems, or drainage structures in areas not owned by the City, but to be maintained by the City.

3.

Detention basins shall be maintained in detention area easements. Detention basins constructed through private development activities shall be maintained by the property owner or neighborhood association. Detention basins constructed for the City, or constructed as a regional facility approved by the City, shall be maintained by City personnel.

4.

All detention easements and drainage easements shall include provisions for adequate maintenance such as dedicated and maintained access easements. These access easements shall be sufficient to provide ingress and egress for maintenance. The minimum width shall be fifteen (15) feet. Access easements are needed only when the area to be maintained does not border a public right-of-way.

Section 24-59.3.3.1 - EASEMENTS FOR ENCLOSED STORM SEWERS, POSITIVE OVERFLOW AREAS AND LOT DRAINAGE

A grading plan shall be prepared and submitted to the City, which indicates typical lot grading for all lots in the subdivision using typical FHA lot grading types (A, B, and C). See Figure 24-59.3.3.1 - Typical FHA lot grading.

24-59.3.3.1 - Typical FHA lot grading

24-59.3.3.1 - Typical FHA lot grading

All storm sewer conduits to be dedicated to the City shall be located in an easement dedicated to the City of Laredo at the time of final platting of the property. The easement shall be at least fifteen (15) feet wide for storm sewers, or wider if the City Engineer requires it for maintenance or other purposes. Special drainage easements for positive overflows on private property shall be a minimum of ten (10) feet wide, or wider if the City Engineer requires it, for maintenance or other purposes.

Accumulated drainage from more than one (1) residential lot (or more than one (1) lot equivalent in the case of staggered or offset lots) shall be contained within a Special Drainage Easement. This easement shall be dedicated to the City at the time of final platting of the property. This shall be a special drainage easement on private property and shall be a minimum of ten (10) feet wide. The easement may be shared with underground utility easements provided those facilities do not impede the calculated runoff. Front to rear lot drainage shall not exceed a maximum slope of five percent (5%). No flow restricting fences, buildings, structures, or other improvements which impede flow shall be placed within these easements.

Single front to rear residential lot drainage, or one (1) lot equivalent in the case of staggered, or offset lots do not require Special Drainage Easement. Front to rear lot drainage shall not exceed a maximum slope of five percent (5%). All lots draining and/or receiving runoff will be identified with a plat note. Flow restricting fences or other structures installed between these lots shall be constructed to the specifications of the engineer of record. Said specifications shall be located on the recorded grading plan. Additionally, the homebuilder shall install a twenty (20) feet wide sod strip along entire rear property line of lots draining onto other lots ten (10) feet strip on upgradient lot and ten (10) feet strip on downgradient lot).

WARNING AND DISCLAIMER OF LIABILITY

The degree of flood protection required by this article is considered reasonable for regulatory purposes and is based on scientific and engineering considerations. Larger floods can and will occur on rare occasions. Flood heights may be increased by manmade or natural causes. This article does not imply that land outside the area of special flood hazards or uses permitted within such areas will be free from flooding or flood damages. This ordinance does not imply that properties shall always be free from flooding or flood damage, surface water stagnation or nonpoint source pollution or that all flood control and water treatment projects to control the quantity and quality of runoff can be constructed effectively. Nothing whatsoever in this ordinance should be construed as or be deemed to create additional duties, on the part of the city, to hold the city liable for any damages incurred in a flood or from adverse water quality, due to drainage runoff. Nothing in this ordinance shall be deemed to waive the city's immunity under state law or reduce the need or necessity for flood insurance.

Section 24-59.4.1 - GENERAL REQUIREMENTS

1.

All operators of construction sites shall use best management practices (BMPs) to control and reduce the discharge, to the MS4 and to waters of the United States, of sediment, silt, earth, soil, and other material associated with clearing, grading, excavation, land filling, and other construction activities to the maximum extent practicable. Any best management practices (BMPs) capable of installation and/or implementation prior to commencement of construction (for example, structural measures) shall be installed and/or implemented prior to commencement of construction at the site or in compliance with a schedule for installation and/or implementation in an applicable Stormwater Pollution Prevention Plan (SWPPP). The best management practices (BMPs) used at construction sites may include, but are not limited to, the following measures:

a.

Ensuring that existing vegetation is preserved where feasible and that disturbed portions of the site are stabilized as soon as practicable in portions of the site where construction activities have stopped for fourteen (14) days, and no further construction is anticipated for an additional seven (7) days, or have permanently ceased;

b.

Use of structural practices to divert flows from exposed soils, to store flows, or to otherwise limit runoff and the discharge of pollutants from the site to the maximum extent practicable;

c.

Minimization of the tracking of sediments off-site by vehicles, the generation of dust, and the escape of other windblown waste from the site;

d.

Prevention of the discharge of building materials, including cement, lime, concrete, asphalt, or mortar, to the MS4 or waters of the United States;

e.

Measures to prevent and contain spills of paints, solvents, fuels, septic waste, and other hazardous chemicals and pollutants associated with construction, and to assure proper cleanup and disposal of any such spills in compliance with state, federal, and local requirements;

f.

Implementation of proper waste disposal and waste management techniques, including covering waste materials, minimizing ground contact with hazardous chemicals and trash, and installing and maintaining covered receptacles for rubbish and garbage to assure that such waste materials are not blown or carried by rainfall runoff from the site;

g.

Timely maintenance of vegetation, erosion and sediment control measures, and other best management practices (BMPs) to maintain them in good and effective operating condition; and

h.

Installation of structural measures during the construction process to control pollutants in stormwater discharges that will occur after construction operations have been completed. Structural measures should be placed on upland soils to the degree attainable. Such installed structural measures may include, but are not limited to, the following: stormwater detention structures (including wet ponds); stormwater retention structures; flow attenuation by use of open vegetative swales and natural depressions; other velocity dissipation devices; infiltration of runoff on site; and sequential systems which combine several practices. Operators of construction sites are only responsible for the installation and maintenance of stormwater management measures prior to final stabilization of the site, and are not responsible for maintenance after stormwater discharges associated with construction activity have terminated.

2.

Qualified personnel (provided by the operator of the construction site) shall inspect disturbed areas of any construction site that have not been finally stabilized, areas used for storage of materials that are exposed to precipitation, structural control measures, and locations where vehicles enter or exit the site, at least once every seven (7) calendar days and within twenty-four (24) hours of the end of a storm that is zero and five tenths (0.5) inches or greater. All erosion and sediment control measures and other identified best management practices (BMPs) shall be observed in order to ensure that they are operating correctly and are effective in preventing significant impacts to receiving waters and the MS4. Based on the results of the inspection, best management practices (BMPs) shall be modified as appropriate, and as soon as is practicable.

3.

Any owner of a site of construction activity, whether or not he/she is an operator, is jointly and severally responsible for compliance with the requirements in this Section 24-59.4.1 of the Code.

4.

Any contractor or subcontractor on a site of construction activity, who is not an owner or operator, but who is responsible under his/her contract or subcontract for implementing a best management practices (BMPs) control measure, is jointly and severally responsible for any willful or negligent failure on his/her part to adequately implement that control measure.

Section 24-59.4.2 - STORMWATER POLLUTION PREVENTION PLAN (SWPPP) SUBMITTAL AND REVIEW

All operators of sites of construction activity, including clearing, grading, excavation, and land filling activities, that result in the disturbance of one (1) or more acres of total land area, or that is part of a common plan of development or sale within which one (1) or more acres of total land area are disturbed, or who are required to obtain an NPDES permit for stormwater discharges associated with construction activity, shall comply as a minimum with the following requirements (in addition to those in Section 24-59.4.1 of this Code and those requirements defined in the most current EPA/NPDES stormwater permit):

Section 24-59.5.4.1 - QUALITY MANAGEMENT CRITERIA

The criteria of the water quality management for the new development and redevelopment is that the water quality effects of the development should not be significantly different from the water quality effects of the same site before construction. Development/redevelopment within the City of Laredo shall provide, at the minimum, one of the following methods for stormwater treatment, provided that the discharges meet the requirements of the City's stormwater NPDES permit and state water quality criteria. More stringent treatment methods may be required by the City Engineer if discharges fail to meet water quality goals. The drainage area for determining treatment volumes shall include all areas draining to the facility (on-site and off-site). If off-site flows are not commingled with on-site flows prior to treatment, they should not be included in the treatment volume.

Method Treatment Volume and Recovery Rate:

a.

Wet Detention: Wet detention treatment volume shall be, at a minimum, the first one (1) inch of runoff. No more than one-half (½) of the volume may be discharged in the first twenty-four (24) hours.

b.

Off-line Retention: Off-line retention diverts the first flush of stormwater runoff to a facility separated from the main line stormwater conveyance system. The treatment volume for off-line retention shall be one-half (½) inch of runoff. The treatment volume shall again be available within a minimum of twenty-four (24) hours and a maximum of seventy-two (72) hours following a storm event, with appropriate on-site soils test submitted to verify the infiltration rate.

c.

On-line Retention or Detention: For on line retention or detention with under drained filtration, treatment volume shall be provided equal to one (1) inch of runoff. Only bottom underdrain systems planted with grass that are capable of recovering the treatment volume within twenty-four (24) hours shall be allowed, to the satisfaction of the City Engineer, to exceed the capabilities of such a bottom underdrain system.

Design criteria and design specifications for the water quality treatment methods described above are outlined in the Stormwater Management Guidance Manual.

Section 24-59.5.4.2 - FLOATABLE CONTROLS

All detention facilities shall incorporate floatable controls (baffles, etc.) to ensure that no floatables are discharged from the facility. The detention facilities shall be regularly checked and any floatables removed as part of the ongoing detention facility maintenance.

Section 24-59.5.4.3 - SPILL CONTROL

All detention facilities shall incorporate in the design of their discharge structures a method for stopping all discharges in case of an accidental spill occurring within the detention facilities drainage area. This discharge control device shall be periodically checked to ensure its continued operation as part of the ongoing detention facility maintenance.

Section 24-59.5.4.4 - BMPs

For residential development/redevelopment areas of more than one (1) acre, and with the approval of the City Engineer or his/her authorized representative, the water quality requirements as stated in Section 24-59.5.4 may be waived in favor of a series of permanent BMPs, i.e., swales, vegetated buffers, small impoundments, etc. that are shown to provide sufficient water quality enhancements to meet the intent of Section 24-59.4.

Section 24-59.5.4.5 - DISCHARGES TO THE RIO GRANDE

For sites discharging directly into the Rio Grande the runoff amounts used for the determination of water quality treatment volume will be fifty percent (50%) greater than those indicated in Section 24-59.4. The only treatment method for water quality shall be off-line retention unless otherwise approved by the City Engineer and the IBWC.

Investigation and/or resolution of the matter in response to the Warning Notice in no way relieves the alleged violator of liability for any violations occurring before or after receipt of the Warning Notice. Nothing in this subsection shall limit the authority of the City Engineer to take any action, including emergency action or any other enforcement action, without first issuing a Warning Notice.

Section 24-59.8.2 - NOTIFICATION OF VIOLATION

When the City Engineer finds that any person has violated, or continues to violate, any provision of this Code, or any order issued hereunder, the City Engineer may serve upon that person a written Notice of Violation.

Within ten (10) calendar days of the receipt of this notice, an explanation of the violation and a plan for the satisfactory correction and prevention of recurrence thereof, to include specific required actions, shall be submitted by the alleged violator to the City Engineer. If the alleged violator denies that any violation occurred and/or contends that no corrective action is necessary, an explanation of the basis of any such denial or contention shall be submitted to the City Engineer within ten (10) calendar days of receipt of the notice.

Submission of an explanation and/or plan in no way relieves the alleged violator of liability for any violations occurring before or after receipt of the Notice of Violation (NOI). Nothing in this section shall limit the authority of the City Engineer to take any action, including emergency action or any other enforcement action, without first issuing a Notice of Violation (NOV).

Section 24-59.8.3 - CONSENT ORDERS

The City Engineer may enter into Consent Orders, assurances of voluntary compliance, or other similar documents establishing an agreement with any person responsible for noncompliance with any provision in this Code or any order issued hereunder. Such documents may include specific actions to be taken by the person to correct the noncompliance within a time period specified by the document. Such documents shall have the same force and effect as the administrative orders issued pursuant to Sections 24-59.8.5, 24-59.8.6, and 24-59.8.7 of this Code and shall be judicially enforceable.

Section 24-59.8.4 - SHOW CAUSE HEARING

The order may direct that the remediation, abatement, and/or restoration be accomplished on a specified compliance schedule and/or be completed within a specified period of time. An order issued under this subsection does not relieve the violator of liability for any violation, including any continuing violation. Issuance of an order under this subsection shall not be a bar against, or a prerequisite for, taking any other action against any responsible party.

Section 24-59.8.7 - EMERGENCY CEASE AND DESIST ORDERS

When the City Engineer finds that any person has violated, continues to violate, or threatens to violate, any provision of this Code, or any order issued hereunder, or that the person's past violations are likely to recur, and that the person's violation(s), or threatened violation(s), have caused or contributed to an actual or threatened discharge to the MS4 or waters of the United States which reasonably appears to present an imminent or substantial endangerment to the health or welfare of persons or to the environment, the City Engineer may issue an order to the violator directing it to immediately cease and desist all such violations and directing the violator to:

1.

Immediately comply with all requirements of this Code; and

2.

Take such appropriate preventive action as may be needed to properly address a continuing or threatened violation, including immediately halting operations and/or terminating the discharge. Any person notified of an emergency order directed to it under this subsection shall immediately comply and stop or eliminate its endangering discharge. In the event of a discharger's failure to immediately comply voluntarily with the emergency order, the City Engineer may take such steps as deemed necessary to prevent or minimize harm to the MS4 or waters of the United States, including immediate termination of a facility's water supply, sewer connection, or other municipal utility services. The City Engineer may allow the person to commence or recommence its discharge when it has demonstrated to the satisfaction of the City Engineer that the period of endangerment has passed, unless further termination proceedings are initiated against the discharger under this Code. A person that is responsible, in whole or in part, for any discharge presenting imminent endangerment shall submit a detailed written statement, describing the causes of the harmful discharge and the measures taken to prevent any future occurrence, to the City Engineer within ten (10) calendar days of receipt of the emergency order. Issuance of an emergency cease and desist order shall not be a bar against, or a prerequisite for, taking any other action against the violator.
