A Traffic Impact Analysis (TIA) shall be submitted to the city with a land use application under any one or more of the following circumstances:

A.

To determine whether a significant effect on the transportation system would result from a proposed amendment to the Newport Comprehensive Plan or to a land use regulation, as specified in ORS 660-012-0060.

B.

ODOT requires a TIA in conjunction with a requested approach road permit, as specified in ORS 734-051-3030(4).

C.

The proposal may generate 500 or more average daily trips or 50 PM peak-hour trips or more.

D.

The proposal may increase use of any adjacent street by 10 vehicles or more per day that exceeds 26,000 pound gross vehicle weight.

E.

The proposal includes a request to use Trip Reserve Fund trips to meet the requirements of Chapter 14.43, South Beach Transportation Overlay Zone.

F.

Existing or proposed approaches or access connections that do not meet minimum spacing or sight distance requirements or are located where vehicles entering or leaving the property are restricted, or the location of an existing or proposed access driveway does not meet minimum access spacing or sight distance requirements.

G.

For phased development on a lot, parcel or tract, the number of vehicle trips shall be the cumulative number of vehicle trips generated for all phases until such time as traffic impact analysis is required pursuant to this section.

A.

Pre-application Conference. The applicant shall meet with the City Engineer prior to submitting an application that requires a Traffic Impact Analysis (TIA). This meeting will be coordinated with ODOT when an approach road to US-101 or US-20 serves the property so that the completed TIA meets both City and ODOT requirements.

B.

Preparation. The submitted TIA shall be prepared by an Oregon Registered Professional Engineer that is qualified to perform traffic engineering analysis and will be paid for by the applicant.

C.

Typical Average Daily Trips and Peak Hour Trips. The latest edition of the Trip Generation Manual, published by the Institute of Transportation Engineers (ITE) shall be used to gauge PM peak hour vehicle trips, unless a specific trip generation study that is approved by the City Engineer indicates an alternative trip generation rate is appropriate. An applicant may choose, but is not required, to use a trip generation study as a reference to determine trip generation for a specific land use which is not well represented in the ITE Trip Generation Manual and for which similar facilities are available to count.

D.

Intersection-Level Analysis. Intersection-level analysis shall occur at every intersection where 50 or more peak hour vehicle trips can be expected as a result of the proposal.

E.

Transportation Planning Rule Compliance. The TIA shall comply with the requirements of ORS 660-012-0060.

F.

Structural Conditions. The TIA shall address the condition of the impacted roadways and identify structural deficiencies or reduction in the useful life of existing facilities related to the proposed development.

G.

Heavy Vehicle Routes. If the proposal includes an increase in ten or more of the vehicles described in Section 14.45.010.D, the TIA shall address the provisions of Section 14.45.020.F for the routes used to reach US-101 or US-20.

H.

Phased Development. If the land use application is part of a phased development, the TIA shall analyze the ultimate build-out of all phases of the project.

The following facilities shall be included in the study area for all TIAs:

A.

All site-access points and intersections (signalized and unsignalized) adjacent to the proposed site. If the proposed site fronts an arterial or collector street, the analysis shall address all intersections and driveways along the site frontage and within the access spacing distances extending out from the boundary of the site frontage.

B.

Roads through and adjacent to the site.

C.

All intersections needed for signal progression analysis.

D.

In addition to these requirements, the City Engineer may require analysis of any additional intersections or roadway links that may be adversely affected as a result of the proposed development.

When a TIA is required, the applicable review process will be the same as that accorded to the underlying land use proposal. If a land use action is not otherwise required, then approval of the proposed development shall follow a Type II decision making process.

When a TIA is required, a development proposal is subject to the following criteria, in addition to all criteria otherwise applicable to the underlying proposal:

A.

The analysis complies with the requirements of 14.45.020;

B.

The TIA demonstrates that adequate transportation facilities exist to serve the proposed development or identifies mitigation measures that resolve the traffic safety problems in a manner that is satisfactory to the City Engineer and, when state highway facilities are affected, to ODOT; and

C.

Where a proposed amendment to the Newport Comprehensive Plan or land use regulation would significantly affect an existing or planned transportation facility, the TIA must demonstrate that solutions have been developed that are consistent with the provisions of ORS 660-012-0060; and

D.

For affected non-highway facilities, the TIA establishes that city Level of Service (LOS) and volume to capacity (v/c) standards, known collectively as city's vehicle mobility standards, have been met as outlined in Table 14.45.050-A; and

Table 14.45.050-A. Vehicle Mobility Standard for City Streets from the Newport Transportation System Plan

¹ Applies to approaches that serve more than 20 vehicles; there is no standard for approaches serving lower volumes.

E.

Proposed public improvements are designed and will be constructed to the standards specified in Chapter 14.44 Transportation Standards.

The city may deny, approve, or approve a development proposal with conditions needed to meet operations, structural, and safety standards and provide the necessary right-of-way and improvements to ensure consistency with the city's Transportation System Plan.
