Louisiana Administrative Code
Title 70 - TRANSPORTATION AND DEVELOPMENT
Part I - Highway Construction
Chapter 11 - Traffic Impact Policy for New Access Requests Affecting Traffic on State Highways
Section I-1101 - Traffic Impact

1. The Louisiana Department of Transportation and Development (LADOTD) has a responsibility to design, operate and maintain highway facilities that are reasonably safe and efficient for prudent drivers using the highway system. At the same time DOTD must allow all property owners reasonable access to the highway system.

2. In an effort to balance these often conflicting needs, this Section was developed to ensure that new or expansion of existing developments generating significant traffic on state highways are evaluated in a consistent manner by using objective data to facilitate decision-making.

3. The department shall review the effectiveness, applicability and efficiency of this rule annually. Changes to this Section shall be promulgated as applicable. Recommendations for change shall be forwarded to the DOTD traffic impact engineer.

1. This Section applies to new or expanding developments, typically generating 100 hourly trips in the peak direction on state highways.

2. This Section also applies to developments on local public or private streets, with an access point within 0.25 of a mile of a state highway.

3. These developments include, but are not limited to:

4. Additional requirements (such as analysis of nearby major intersections as determined by DOTD) may be necessary for large commercial centers and regional shopping malls.

5. This Section, in certain situations, may apply to new, smaller developments located on congested highway corridors, as determined by the district traffic operations engineer. Congested highways are discussed in the traffic impact policy referenced in Paragraph E.1.

6. The district traffic operations engineer may, in his discretion, waive the requirement for a traffic impact study for developments marginally meeting minimum traffic thresholds.

1. access to interstate and other controlled-access facilities;

2. individuals requesting single-family residential access; or

3. access to local public and private streets for developments which are greater than 0.25 of a mile from the state system.

1. Prior to any permit requests, land developers shall meet with the DOTD district traffic operations engineer and the district permit specialist for a pre-application meeting during preliminary site planning for the development. The purpose of this meeting is to discuss the proposed development and determine if a traffic impact study is warranted.

2. The developer shall be notified within seven calendar days after the pre-application meeting whether or not a traffic impact study is required. The decision will be based on the preliminary site plan layout and anticipated additional traffic.

3. The DOTD will coordinate with the appropriate local authorities for developments not abutting the state highway system.

1. When a traffic impact study is required by DOTD, it shall be prepared and sealed by a professional engineer licensed by LAPELS, before an application for access is submitted. The study will include all information as outlined in the DOTD traffic impact policy, a detailed guidance document which includes forms, roadway classification, traffic volume criteria and mitigation strategies. This document may be obtained from the district office, or the department's website, or from DOTD headquarters in the office of the traffic impacts engineer. The purpose of the traffic impact study is to:

1. The developer is responsible for mitigating traffic caused by the development.

2. All road improvements constructed by the developer shall comply with the latest DOTD standards and specifications.

1. No permit applications will be accepted until DOTD provides the developer with a letter of compliance indicating the approval of the traffic impact study and the traffic mitigation required.

2. The letter shall be attached to any permit application.

1. Traffic Mitigation is a roadway improvement or improvements designed to minimize congestion and improve the safety of the highway system.

2. The required mitigation shall be constructed prior to completion of the new development.

3. Types of mitigation include, but are not limited to:

1. The office of the DOTD district traffic operations engineer and the DOTD Headquarters (HQ) traffic impact engineer, if requested for a joint review, will review the traffic impact study. The department shall take one of the following actions.

1. Following are provisions for a first level appeal of the traffic impact review process for developers which disagree with the DOTD decision on traffic mitigation.

2. The traffic impact review committee shall be composed of representatives of the following divisions within the DOTD. Each member may appoint a substitute if he or she is unable to attend a meeting:

3. The traffic impact review committee, pursuant to a majority vote, may arbitrate and resolve disputes which arise during the review process and grant or deny relief to appealing parties.

4. The appealing party must bring his/her complaint before the traffic impact review committee no later than 30 calendar days after notification of the decision of DOTD.

5. Upon receipt of the appeal, the traffic impact review committee will schedule a meeting to review the appeal. The meeting will be scheduled not earlier than 14 calendar days and not more than 39 calendar days after receipt of the appeal. The traffic impact review committee shall give due notice of the meeting time and place to those filing the appeal and shall render a decision on its action within 14 calendar days of its meeting. The maintenance division shall also be notified of the pending requirements for permit purposes.

6. The party appealing the decision shall submit the written reason for the appeal, together with any supporting documents deemed applicable by the developer, to the Department of Transportation and Development, Traffic Engineering Development Section, 1201 Capitol Access Road, Baton Rouge, LA 70802. Such submittal must be received at least 14 calendar days before the Traffic Impact Review Committee meeting.

7. The submittal will be checked by the department within 14 calendar days of its receipt. If the information deemed necessary for a proper review is not complete, the appealing party will be notified and the appeal will then be postponed at least one month.

8. The party submitting the appeal may appear before the traffic impact review committee to offer a brief explanation of the complaint.

9. Failure to submit an appeal in a timely manner shall constitute a denial of the traffic impact appeal.

1. Should the appeal of the developer be rejected by the traffic impact review committee, the developer may appeal the decision in writing within 30 calendar days from receipt of the initial decision to the Department of Transportation and Development, Attn: Deputy Secretary, 1201 Capitol Access Road, Baton Rouge, LA 70802.

2. The second traffic impact review committee shall be composed of the following:
