IV. PRODEDURES

The procedures for the City of Santa Fe Neighborhood Traffic Management Program (NTMP) include four components: Eligibility and Ranking, Plan Development, Plan Approval and Implementation, and Project Evahiation. These components are outlined below.  

ELIGIBILITY AND RANKING

Upon receiving a complete application package including the required petition of support, staff evaluates the eligibility of the proposed project. The eligibility is determined according to the following point system.

Eligibility Criteria - Local Street Projects
The first type of NTMP project is the Local Street Project. This type of project focuses on the treatment of a neighborhood street that is experiencing traffic problems. The street must be designated as a local street on the adopted Functional Road Classification (FRC) Map of the City of Santa Fe. Generally a Local Street Project should consist of treatment of a single local street. If the basic criteria discussed above are met then the proposed street is studied and scored based on the criteria described in Table 1.

Table 1 - Eligibility Criteria for Local Street Projects
Criteria Points Basis for Point Assignment
Volumes 0 to 30 Measure of Vehicles Per Day (vpd):
0-5OO vpd = 0 pts.; 501-750 vpd = 10pts.; 751-l000vpd = 20pts.; over 1001 vpd = 30 pts.
Cut-through traffic 0 to 25 Measure of Percent by which cut-through traffic exceeds local traffic (%):
0-25% = 0; 26-50% = 5 pts.; 51%-100% = 15 pts.; above 100% = 25 pts.
Speeds 0 to 45 Measure of Miles Per Hour by which the 85th percentile speed exceeds the posted speed limit (mph):
0-5 mph = 0pts.; 6-10 mph = 15 pts.; 11-15 mph = 30 pts.; over l5mph = 45pts.
Total Eligibility Points Possible 100  


The street must receive a minimum score of 40 points in order to be eligible for a Local Street Project.

Eligibility Criteria - Complex Traffic Management Projects
The second type of NTMP project is the Complex Traffic Management Project. These projects consist of traffic management on collector and minor arterial streets or, in some cases, on local streets that because of other factors are placed into the complex street category. Complex traffic management projects will consider streets that are emergency response routes or priority snow removal routes (as designated on the city's Emergency Response Route and Snow Removal Maps contained in the appendices of this document), or which result in a significant diversion of traffic, and will look at a variety of possible treatments for the street. Because treatment of collectors and minor arterials may cause diversion of traffic onto surrounding streets, the project will entail a more detailed study of the street network throughout the neighborhood. The complex project may look at other issues along the street such as access points, enhancment of pedestrian facilities, median treatments, and others.

Following are the basic criteria for a Complex Traffic Management Project:



If these basic criteria are met, then the proposed street is studied and scored according to the criteria in Table 2.

Table 2 - Eligibility Criteria for Complex Traffic Management Projects
Criteria Points Basis for Point Assignment
For Minor Arterials only: Volumes 0 to 40 Measure of Vehicles Pet Day (vpd):
0-2000 vpd = 0 pts.; 2001-4000 vpd = 10 pts.; 4001-6000 vpd = 20 pts.; 6001-10,000 30 pts.; over 10,000 vpd = 40 pts.
  OR  
For Collectors only: Volumes 0 to 40 Measure of Vehicles Per Day (vpd):
0-1000 vpd = 0 pts.; 1001-2000 vpd = 10 pts.; 2001-3000 vpd = 20 pts.; 3001-5000 = 30 pts.; over 5000 vpd = 40 pts.
  AND  
Speeds 0 to 40 Measure of Miles Per Hour by which the 85th percentile speed exceeds the posted speed limit (mph):
0-5 mph = Opts.; 6-10 mph = 20 pts.; 11-15 mph = 30 pts.; over l5 mph = 40 pts.
Adjacent Residential Zoning 0 to 20 Percentage ofland adjacent to the street which is residentially zoned (%):
0-50% = 0 pts.; 51%-75% = 10 pts.; above 75% = 20 pts.
Total Eligibility Points Possible 100  


A street must receive a minimum score of 60 points in order to be eligible for a complex traffic management project.

Ranking Criteria for All NTMP Projects
Once a street is determined to be eligible for the NTMP, it is ranked along with other eligible projects of its same type to determine the priority ranking of projects for the funding that is available. In addition to the points awarded to each project in the determination of eligibility, all projects can be awarded additional points in any of the categories listed in Table 3.2

2 Analysis of accident rates could be useful in determining the ranking of Complex Traffic Management Projects, although the accident rate information currently available is not adequate for such analysis. Accident information will be reviewed in the Plan Development phase of all NTMP projects.


Table 3 - Ranking Criteria for All NMTP Projects
Ranking Criteria Points Basis for Point Assignment
Sidewalks 0 to 15 Points assigned for lack of existing continuous sidewalk along street:
Existing on both sides = 0 pts.; Existing on one side = 5 pts.; Existing on no sides = 10 pts.; no sidewalks and no shoulders = 15 pts.
Pedestrian Facilities 0 to 15 5 points are assigned for each existing pedestrian facility along street, including designated bike routes, designated elementary school crossings and/or areas with observed pedestrian usage (Maximum 15 points).
Density of Adjacent Residential Zoning 0 to 10 Points assigned for density of adjacent residential zoning as follows:
Majority of units less than R5 = 0 points; Majority of units at R5 = 5 points; Majority of units greater than R5 = 10 points. Tie of 2 categories results in 5 points.
Total Ranking Points Possible 40  


A project is able to receive a maximum of 100 points in the eligibility phase and a maximum of 40 points in the ranking phase for a possible total of 140 points. Based upon the points assigned to each project through these two phases, the projects are ranked.

If more than one project in the same track receives the same number of eligibility and ranking points, those projects shall be prioritized according to the date that they were deemed eligible for the NTMP.

If an eligible project is not sufficiently prioritized to receive funding in the year in which it is determined eligible, then ten additional points are added to its overall score in each subsequent year until it is prioritized for funding. A project can remain on the eligibility list for a maximum of four years awaiting prioritization for funding. After that it would be dropped from the NTMP.



 

PLAN DEVELOPMENT
Local Street Projects that are prioritized move directly into the plan development process. Complex Traffic Management Projects, however, often require identification of additional resources for their planning and implementation. When resources are identified for a priority Complex Traffic Management Project, that project moves into the plan development phase.

A Neighborhood Traffic Management Plan for either a Local Street Project or a Complex Traffic Management Project consists of the following components:
If a project includes significant diversion of traffic because of the construction of physical barriers, the project area must be expanded to include a larger "affected area" for the project. What is considered a significant volume of traffic will be decided by the Citizen Traffic Committee with Traffic Division staff assistance. The affected area is also defined by the Citizen Traffic Committee and Traffic Division staff.

Plan Development - Local Street Projects


Plan Development - Complex Traffic Management Projects

The development of a plan for a Complex Traffic Management Project may require hiring a consultant to assist with planning, design and implementation of the project. The complex project may require additional activities to involve the public throughout the larger study area, additional traffic measurement and analyses, the development of iterative conceptual plans, the surveying of residents and businesses in the project area to measure support, and other activities related to the development of final plans and implementation.
 
PLAN APPROVAL & IMPLEMENTATION

Plan Approval for All NTMP Projects
A survey process is used as part of all NTMP projects to measure the support of the traffic management plan by project area residents and property owners. A description of the preferred traffic management plan alternative and a survey are mailed to all residents and property owners in the project area.

The project area is defined by staff at the initiation of each project. For Local Street Projects the project area usually contains those properties along the subject street. For Complex Traffic Management Projects the project area may include properties along the subject street(s) and along adjacents street(s) that are impacted by the project.

Each resident household and each property owner are allow one response to the survey question. A response time for the surveys to be returned is determined by Traffic Division staff and the Citizen Traffic Committee. The response time shall fall between three to six weeks from the date the survey is mailed. Final plan approval is contingent upon the Traffic Division receiving back at least 60% of all of the surveys distributed showing support for the preferred plan alternative. This is required for the Traffic Division to move ahead to plan implementation.

Although they do not receive a survey, the residential associations and City Council members in the area are notified about the preferred traffic management plan alternative.

Implementation - Local Street Projects


Implementation - Complex Traffic Management Projects
 

Project Evaluation

For all projects, an evaluation of the traffic devices is to be performed six months to twelve months after installation. This evaluation will include appropriate studies, such as volume, speed, etc., on the subject street(s) to determine the effectiveness of the devices.

An important aspect of the evaluation of all NTMP projects is related to the impact of unintended, rerouted traffic onto other neighborhood streets. It is important not to divert traffic from one local street to another. NTMP Policy #3 states that "the amount of rerouted traffic that is acceptable will be defined on a project-by-project basis by the Citizen Traffic Committee for that project and city staff. Generally, adjacent local streets should not receive an increase of more than 250 vehicles per day or an increase in traffic greater than 50%, whichever is less."

For all NTMP projects, studies will be undertaken in and around the project area in the Project Evaluation phase to measure any impacts on the surrounding area. If staff determines that "after" conditions on other streets in the area show a high level of traffic diversion as a result of the traffic management project, the city will explore methods for addressing those diversion problems. NTMP Policy #3 states that "If adjacent streets receive higher than acceptable levels of rerouted traffic, additional studies will be undertaken by staff in order to consider possible mitigation of those impacts."
