These guidelines are also to be considered in conjunction with other applicable guidelines for Studies that may be required for the development. This document and process do not supersede the guidelines and standards that are in effect for roads and highways governed by the Regional of Peel or the Ontario Ministry of Transportation (MTO) within the study area.

4 Town of Caledon TIS Terms of Reference and guidelines 5 | P a g e 1. Introduction Purpose The main purpose of a Transportation Impact study ( TIS ) is to demonstrate that the Transportation impacts of a proposed development or redevelopment will be manageable and that the Transportation aspects of the proposal are consistent with the objectives of the Town of Caledon . The TIS also provides the basis for the identification and evaluation of Transportation -related improvements or measures to be included as conditions of approval for the development or redevelopment application.

5 guidelines The Transportation Division of the Town of Caledon has prepared these guidelines to streamline the approval process and provide a standardized framework for consultants to follow when submitting the TIS for review. The guidelines should be complemented with good Transportation engineering judgment. For further information regarding Region of Peel requirements refer to the Region of Peel Traffic Impact study guidelines . Timing of Submission Before approval of the draft plan for the subdivision or other planning application as required through the pre-consultation process, the Transportation Impact study shall be submitted to the Town of Caledon and the Region of Peel as part of the approval process.

6 Types of Developments Requiring TIS There are some considerations in determining the need, elements and level of detail for a TIS. Generally a TIS would be required when one or more of the following are anticipated/present: The development proposal will add more than 100 peak-hour directional vehicle trips to the Transportation system, based on the rates outlined in the Institute of Transportation Engineers (ITE) Trip Generation Manual; The development is planned with an access to an arterial roadway within 200 meters of a signalized intersection; The development is located in an area of high roadway congestion, high operating speeds, and limited sight distance where safety is an issue.

7 The development, its access or type of operation is not envisaged by the Town s Official Plan or the Zoning-by-laws; Town of Caledon TIS Terms of Reference and guidelines 6 | P a g e The development or redevelopment proposal requires amendment of the official plan; As part of the proposed development, a new traffic signal is proposed to be installed on a Town or Regional roadway; In the opinion of the Town or Region, the development has the potential to create adverse operational and safety impacts on the road network. Examples include the following: Inadequate horizontal and vertical sight distances at access points The proximity of the proposed access points to other existing driveways or intersections Lack of existing turn lane(s) on the adjacent roadway at the proposed access point(s) The vehicular traffic generated by the development/redevelopment results in volume to capacity ratios at a signalized intersection exceeding for the overall intersection and/or for an individual through or turning movement If in the opinion of the Town, the previous TIS prepared for the same site is outdated.

8 The onus will be on the proponent to demonstrate that a Transportation Impact study is not required. The above criteria are necessarily general and in view of the lack of definitive criteria to establish the need for and scope of a TIS for a particular proposal, the Proponent shall consult with Town Staff, to determine site-specific TIS requirements. 2. study Requirements Staff Consultation Requirement It is imperative that before commencing a TIS, the consultant meet with Town and Regional staff, if required, to inquire about other area developments and Transportation improvements and to present the terms of reference, including the purpose, structure, and scope of the work to be undertaken.

9 The Town will review and comment on the assumptions and if available, provide traffic data at the proponent s request. A nominal fee may apply to data requests in accordance with Town and Region practices and by-laws. The terms of reference shall include: study area limits Level of effort for describing auto, transit, cycling and pedestrian infrastructure Horizon year(s) for analyses Peak periods for analyses Town of Caledon TIS Terms of Reference and guidelines 7 | P a g e Method of predicting site traffic and transit volumes Method of establishing background traffic and transit volumes Software program for intersection capacity analyses List of traffic data requested Scope and Components The level of detail and the required components of the TIS will be a function of the location, size, and operations of the development proposal.
