§ 114-200. Traffic Study.

(a)

In addition to all application requirements, traffic studies by a qualified traffic engineer, as determined by the Planning Director, who is a licensed engineer in the state, shall be required as follows, in accordance with the Monroe County Traffic Report Guidelines Manual:

(1)

Traffic studies shall be required for proposed development as shown in the table below, based on the anticipated number of vehicle trips per day generated by the site:

Required Traffic Studies
Gross Daily Trip Generation*	Project Location	Type of Report Required
11—249	Segments of U.S. 1 designated as Inadequate Capacity or Marginally Adequate Capacity according to the biennial assessment of public facilities capacity report (see Sec. 114-2).	Level 1
250—500	All Areas	Level 2
>500	All Areas	Level 3

 

*Gross Daily Trip Generation shall be calculated in accordance with the methods used in the Institute of Transportation Engineers, Trip Generation Manual, current edition.

(2)

Level 1 traffic studies shall include the following:

a.

Provide a detailed assessment of the number of additional daily trips generated by the development as calculated by the most current edition of the ITE Trip Generation Manual;

b.

Analysis shall be based on the project's expected trip generation broken into primary, pass-by, and internal trips, as well as the directional split and trip lengths to estimate the number of additional primary trips on US-1;

c.

The report shall provide recommendations for mitigating any project trips in excess of the LOS C standard; and

d.

The applicant shall be responsible for construction of the improvements recommended in the study.

(3)

Level 2 traffic studies shall include all elements of a Level 1 study, plus the following:

a.

Ensure adequate access to the street system;

b.

The study shall also include traffic diagrams detailing the peak hour and AADT traffic counts at intersections and turning movements;

c.

The data shall include background traffic (existing traffic plus traffic from approved projects) and proposed project traffic;

d.

Any recommendation for a traffic signal will required an alternatives analysis;

e.

All roadways and intersections along the access routes shall be evaluated for traffic safety and visibility; and

f.

The study shall recommend improvements necessary to meet the accepted traffic standards for Monroe County.

(4)

Level 3 traffic studies shall include all elements of both Level 1 and Level 2 studies, plus the following:

a.

Ensure all intersections serving the development will operate at or above the County's LOS standards;

b.

All signalized and signalized intersections within one mile of the development shall be analyzed; and

c.

The study shall recommend mitigation measures for deterioration of LOS at signalized and/or unsignalized intersections.

(5)

All required traffic studies shall indicate that U.S. 1 has sufficient available capacity to operate at or within five percent (5%) of a level of service of C as measured on an overall (countywide) basis as measured by the U.S. 1 Level of Service Task Force Methodology. If the proposed development will reduce the level service to more than 5% below a level of service C, the traffic study shall indicate mitigation measures required to maintain the adopted level of service.

(6)

All Level 3 traffic studies shall indicate that every paved County road within one (1) mile of the parcel proposed for development and all bridges on U.S. 1 within six (6) miles of the parcel proposed for development shall have sufficient available capacity to operate at minimum peak hour at or within five percent (5%) of a level of service D as measured by the methodology identified in the most recent edition of the Highway Capacity Manual. If the proposed development will reduce the level service on such roads and/or bridges to more than 5% below a level of service D, the traffic study shall indicate mitigation measures required to maintain the adopted level of service

(7)

Traffic studies shall not be required for applications for a single family residence.
