§ 16.07 Traffic Impact Analysis (TIA).

(a) 
Purpose.
The purpose of a traffic impact analysis is to assist in determining the adequacy of the road network to serve a proposed subdivision or development and whether off-site road dedication and/or improvements are required to mitigate the effects of the proposed subdivision or development.
(b) 
When Required.
(i) 
A traffic impact analysis shall be required with any application for a preliminary and final plat, site plan or other plan for which:
A. 
The development exceeds an average of 100 parking spaces per driveway;
B. 
The development generates traffic in excess of 1,000 average daily trips, based upon the latest edition of the Institute of Transportation Engineers (ITE) Trip Generation Manual; or
C. 
Any driveway in the development is projected to serve 100 ingress vehicles or more in the peak hour of the adjacent street;
(ii) 
The City Engineer may also require a traffic impact analysis for:
A. 
Any project that proposes access to a street with a current Level of Service "C" or below, or will meet an LOS of C or below as determined by the future land use plan;
B. 
Any case where the previous TIA for the property is more than two years old; or
C. 
Any case where the Director and the City Engineer determine that the increased land use intensity will result in increased traffic generation or traffic conflicts such as turning movements and topography may affect the speed or safety of the roadway.
(iii) 
A traffic impact analysis shall be submitted with a preliminary plat, site plan or as otherwise required by the Director to address situations not addressed herein. An updated traffic impact analysis shall be submitted with each final plat submitted for review if the initial TIA is more than two years old or if staff determines that off-site traffic patterns since the initial TIA have changed that could negatively affect the project scope and initial intent. The traffic impact analysis shall be updated whenever a plat is modified to authorize more intensive development.
(iv) 
If a TIA is required with the approval or review of any plat or plan, the TIA must be completed prior to submittal of the plat or plan to the City for review or, if a plat is involved, the applicant shall provide a letter waiving the 30-day approval period at the submission of the plat. If the applicant chooses to have a completed TIA prior to submittal of a plat, the applicant shall pay a sum of 50 percent of the estimated cost prior to the City retaining a consultant. Disclosure of the results of the TIA shall not be made until the balance of the costs has been paid. If payment is not forthcoming, the City shall cause an interest-bearing lien to be placed on the property to recover costs.
(c) 
Study Scope.
When a traffic impact analysis is required, the scope of the analysis shall be determined during or soon after the pre-application conference. No application requiring a traffic impact analysis may be made until the scope of the required analysis has been determined. The Director or City Engineer may involve representatives of or request assessments from other agencies and departments. The elements to be determined during the pre-application conference shall include the following.
(i) 
Definition of Impact Area.
The points of access and key streets and intersections that may be affected by development of the subject tract constitute the impact area [sic] shall be determined. Traffic recorder and turning movement assessment locations shall be determined.
(ii) 
Period of Analysis.
Periods of analysis shall include average daily traffic, peak AM and PM and/or weekend peak hour.
(iii) 
Analysis Scenarios.
Scenarios for analysis shall include existing conditions, opening year conditions with and without development, and 10 years after opening with and without off-site development.
(iv) 
Process.
The process for determining trip generation and distribution shall include trip generation category, diversion assumptions, distribution assumptions and capacity analysis.
(v) 
Growth Rate Assumption.
The rate of growth assumed in background traffic assumptions shall be determined.
(vi) 
Future Development.
Developments that are planned in the area that have been approved or are under review shall be considered.
(d) 
Traffic Study Elements.
A traffic impact study shall include the following elements.
(i) 
Existing Condition Survey.
A. 
Street System Description.
The street system shall be described including geometric features, lane usage, traffic control, signage, sight distances and adjacent uses and curb cuts.
B. 
Traffic Volumes.
Existing traffic volumes shall be provided for the impact area including both average daily traffic and "design" peak hour volumes. Average daily trips shall be derived from the latest available counts taken by the City, North Central Texas Council of Governments, or Texas Department of Transportation. Peak hour volumes shall be obtained from field counts. Data shall be adjusted for daily and seasonal variations. Turning movement counts for the peak hour shall be provided for critical intersections. Peak hour periods shall be as determined at the pre-application meeting.
C. 
Capacity Analysis.
Existing capacity of signalized and unsignalized intersections shall be provided.
D. 
Other.
Other items may be required at the discretion of the Director or City Engineer depending upon the type and scale of the project. These may include but are not limited to: queue length analysis, pedestrian counts, accident data, traffic speeds (both 50th and 85th percentile) and stopping sight distances.
(ii) 
Future Without Development.
Capacity analysis is to be provided for opening year and plus 10-year for key intersections (and roadway segments where appropriate) without the development but including any planned developments. The analysis shall be based upon the Highway Capacity Manual or other methodologies approved in advance by the Director or City Engineer.
(iii) 
Future With Development.
A. 
Projections of the daily and peak hour traffic generation of the project shall be made using the latest edition of the ITE Trip Generation Manual unless the Director or City Engineer determines that locally derived data will provide more accurate forecasts. Data from similar facilities may be used where the information is not available from ITE.
B. 
The projected trips shall be distributed onto the road network as agreed in the pre-application conference.
C. 
Capacity analysis for opening year and plus 10-year for key intersections (and roadway segments where appropriate) shall be provided.
D. 
Special analysis may be required to determine warrants for signalization, minimum safe sight distances, gap analysis, turning radius requirements, queue length analysis, turning lane length analysis, curb cut locations or similar requirements. If projected traffic combined with existing traffic warrants signalization, then adequate signalization shall be the responsibility of the applicant.
(iv) 
Mitigation Plan.
Where the analysis indicates that the project will create deficiencies in the impact area, improvements shall be recommended which shall include projected cost estimates. The design of improvements shall be in accordance with specifications of the City Engineer and, where appropriate, the Texas Department of Transportation. The mitigation plan shall also include any dedications necessary to comply with the minimum road standards described below. Where the Planning and Zoning Commission determines that a mitigation plan is not adequate to address the traffic impacts of the project, it may serve as a basis for denial of the plat. Where the Director determines that a mitigation plan is not adequate to address the traffic impacts of the project, it may serve as a basis for denial of a development plan.
(e) 
Conduct of TIA.
The traffic impact analysis shall be conducted by the City who shall calculate the rough proportionality of the impacts of the subdivision or proposed development. The applicant shall pay all incurred charges prior to the approval of any plat or plan unless otherwise required herein.
(f) 
Right-of-Way Dedication.
Street right-of-way shall be dedicated as required in the Thoroughfare Plan or as determined by the TIA. If multiple lanes are required, the location and placement shall be determined by the City Engineer. In lieu of construction, the City Engineer may require that the cost for construction be placed in escrow if roadway improvements are planned or can be planned by the City within a foreseeable future as determined by the City Engineer, who may defer to the City Council for determination. Additional improvements such as deceleration lane, curb cut location, median openings, stacking lanes and other such issues shall be required as determined in the traffic impact analysis and approved by the City.
(g) 
City Evaluation and Action.
The City shall evaluate the adequacy of the traffic impact analysis prepared by the applicant. Based upon such evaluation, the City shall determine:
(i) 
Whether the application may be approved in the absence of dedication of rights-of-way or construction of improvements to each affected thoroughfare; and
(ii) 
The extent of the applicant's obligations to make such dedications or improvements. The City shall condition the approval of the plan or plat application on one or more of the following performances by the applicant:
A. 
Delay or phasing of development until thoroughfares with adequate capacity or intersection improvements are constructed;
B. 
A reduction in the density or intensity of the proposed development sufficient to assure that the road network has adequate capacity to accommodate the additional traffic to be generated by the development;
C. 
The dedication or construction of thoroughfares or traffic-control improvements needed to mitigate the traffic impacts generated by the proposed development.
(h) 
Deferral of Obligation.
Upon request of the applicant, the obligation to dedicate or improve thoroughfare rights-of-way or to make intersection improvements imposed on an application may be considered by the City to defer to a later stage of the development process. As a condition of deferring the obligation to dedicate rights-of-way for or to improve thoroughfares, which deferral shall be in the sole discretion of the City, the City shall require the developer to execute an agreement specifying the amount and timing of the rights-of-way dedication or improvements to thoroughfares.
(i) 
Cash Contributions.
In lieu of the obligation to improve thoroughfares or make traffic-control improvements, the applicant may propose to make equivalent cash contributions based upon the development project's proportionate share of the costs of improvements, which the City in its sole discretion may accept. Any funds accepted by the City shall be earmarked for construction of the improvements for which the contribution was made.
(j) 
Options.
Whenever the proposed development's share of the costs of a thoroughfare or traffic-control improvement needed to mitigate traffic generated by the development is less than 100 percent, the City in its sole discretion may do the following:
(i) 
Participate in the excess costs; or
(ii) 
Aggregate the costs of improving multiple thoroughfares or intersections identified in the traffic impact analysis, and require improvements to only some of the thoroughfares or intersections affected by the development; or
(iii) 
Require surety to cover the cost of the developer's responsibility.
(k) 
Appeal of Road Adequacy Conditions.
Any appeal of a disapproved plan or plat resulting, in full or in part, from a determination that the mitigation plan was insufficient may be taken to the City Council, whose decision shall be final. The appeal shall include the following.:
(i) 
The appeal shall allege that recommended conditions requiring dedication or construction of thoroughfares or traffic-control improvements are not roughly proportional to the nature and extent of the traffic impacts on the road network created by the development being proposed.
A. 
The applicant shall provide a study in support of the appeal[.]
(ii) 
The City Council shall consider the appeal and determine whether the requirements are roughly proportional to the nature and extent of the impacts on the road network created by the development proposed. Following such determinations, the City Council may take any of the following actions regarding the road adequacy portion of the appeal only:
A. 
Deny the appeal, upon determining that the required dedications of rights-of-way for or improvements to thoroughfares or traffic-control improvements are roughly proportional to the nature and extent of the impacts created by the development, and order that such dedication or improvements be made as a condition of approval of the application;
B. 
Deny the appeal, finding that the dedication or improvement requirements are inadequate to achieve road adequacy, and either deny the application or require that additional dedications of rights-of-way dedication for or improvements to thoroughfares, or traffic-control improvements, be made as a condition of approval of the application;
C. 
Grant the appeal and waive in whole or in part any dedication or construction requirement that is not roughly proportional; or
D. 
Grant the appeal, and direct that the City participate in the costs of acquiring rights-of-way or constructing improvements sufficient to achieve proportionality.

(ii) 
Basic Design Objectives.
A. 
In general, the stormwater management system shall be designed and constructed in accordance with the adopted Storm Water Ordinance and Design Manual and in a manner that promotes the development of a network of both natural and built drainage ways throughout the community and so as to:
1. 
Retain natural floodplains in a condition that minimizes interference with floodwater conveyance, floodwater storage, aquatic and terrestrial ecosystems, and ground and surface water;
2. 
Reduce exposure of people and property to the flood hazard and nuisance associated with inadequate control of runoff;
3. 
Systematically reduces the existing level of flood damages;
4. 
Ensure that corrective works are consistent with the overall goals of the City;
5. 
Minimize erosion and sedimentation problems and enhance water quality;
6. 
Protect environmental quality, social wellbeing and economic stability;
7. 
Plan for both large flooding events and smaller, more frequent flooding by providing both major and minor drainage systems;
8. 
Minimize future operational and maintenance expenses;
9. 
Reduce exposure of public investment in utilities, streets and other public facilities;
10. 
Minimize the need for rescue and relief efforts associated with flooding and generally undertaken at the expense of the public;
11. 
Acquire and maintain a combination of recreational and open space systems utilizing floodplain lands; and
12. 
Preserve natural drainage patterns so as to prevent erosion, maintain infiltration and recharge of groundwater, and attenuate the harm of contaminants collected and transported by stormwater.
(iii) 
General Design Requirements.
A. 
The stormwater management system shall be separate and independent of any sanitary sewer system and its use shall not interfere with the operation and maintenance of road networks or utility systems.
B. 
Any use of retaining walls or similar construction shall be indicated on construction plans for such structure.
C. 
To preserve the use of land and to improve the quality of aesthetics along streets and roads, no open stormwater detention facility shall be located within the front street yard or exterior side yard of a property fronting, siding or backing to an Interstate or any arterial unless determined by the Director and City Engineer that placing such detention underground is technically unfeasible. Underground detention shall be allowed on any part of the lot with the exception of under a structural foundation of a building, unless otherwise designed by a professional engineer. The surface area of a parking lot may be used as part of the detention facility when approved by the City Engineer. Above-ground detention visible from a public street shall receive heightened landscaping to screen such as determined by the Director, unless it is created and improved as an open space amenity, as approved by the Director.
D. 
No lot or building site shall take access to a public street across a waterway unless such access is approved by the City Engineer.
E. 
Areas subject to inundation under design storm conditions shall be indicated with the minimum floor elevation of each lot so affected on the preliminary plat. The appropriate final review authority for plat approval may, when it deems necessary for the protection of the health, safety or welfare of the present and future populations, place restrictions on the subdivision, regarding the design and use of areas within a drainage way that may also include a minimum finished floor elevation 12 inches or more above design storm conditions.
F. 
Design of major drainage ways through a subdivision and major structures such as box culverts or bridges across a major drainage channel shall be coordinated with the requirements of the County when any portion of the subdivision lies outside the City limits, and when applicable, a letter requesting a local floodplain map amendment from the Federal Emergency Management Agency (FEMA) shall be provided prior to final construction plan approval.
(iv) 
Drainage Easements.
The requirements set forth herein are not intended to be exhaustive and wherever it is necessary to make additional requirements in order to maximize the effectiveness of the drainage plan in question, such requirements shall be made by the Commission.
A. 
General Requirements.
Where a subdivision is traversed by a watercourse, drainage way, channel or stream, a stormwater easement or drainage right-of-way shall be provided that conforms substantially with the contours of such watercourse. Additional width may be required for necessary flood control measures. The minimum requirements for such easements shall be based on the 100-year flood. When parking lots or other approved use areas serve a dual function, including detention, those areas shall be designated on the plat or plan as detention areas. The drainage shall, at a minimum, be maintained by an open channel with landscaped banks having adequate width to contain the volume of flow generated by the design storm under ultimate development conditions, unless otherwise required herein.
B. 
Design Requirements.
1. 
Where topography or other conditions are such as to make impractical the inclusion of drainage facilities within the street right-of-way, as determined by the City Engineer, perpetual unobstructed easements a minimum of 16 feet in width for such drainage facilities shall be provided across property outside the road lines and with satisfactory access to the road. Easements shall be recorded by separate instrument and indicated on the plat. Drainage easements shall be carried from the road to a natural watercourse or to other drainage facilities.
2. 
When a proposed drainage system will carry water across private land outside the subdivision, drainage easements shall be secured and recorded by separate instrument in the property records of the County and shown on the construction plans.
3. 
Low-lying lands along watercourses subject to flooding or overflowing during storm periods shall be preserved and retained in their natural state as drainage ways except where modification can be shown to benefit the community and as approved by the Planning and Zoning Commission. All development activity within the regulatory floodplain must comply with City and FEMA floodplain management regulations.
4. 
All sedimentation, filtration, detention and/or retention basins and related appurtenances shall be within a drainage easement that is recorded in the property records of the County. The owners of the tracts upon which are located such easements, appurtenances, and detention facilities shall maintain same and be responsible for their upkeep. Notice of such duty to maintain shall be shown on the plats.
(e) 
Other Utilities.
(i) 
Utility services shall be placed underground unless a temporary above-grade connection is approved by the City.
(ii) 
The applicant shall make the necessary arrangements including any construction or installation charges with each of the serving utilities for the installation of such facilities and shall be subject to all applicable laws and regulations for their construction. Transformers, switching boxes, terminal boxes, meter cabinets, pedestals, ducts, and other facilities necessarily appurtenant to such underground utilities may be placed above the ground in a location approved by the City. Electric transmission and distribution feeder lines and communication long-distance trunk and feeder lines and necessary appurtenances may be placed above the ground. Such facilities shall be placed within easements or public rights-of-way.
(iii) 
Other improvements not specifically mentioned herein but found necessary due to conditions found on the site by the City may be required.
