LOS Background

The first effort by ACHD for variable LOS occurred when the impact fee program was established in the early 1990s. At that time various roadways showed the need for additional capacity in the future but a decision was made by ACHD to not alter certain roadways to accommodate capacity (accept congestion) within the Capital Improvements Plan (CIP). Examples of these were: Harrison Blvd, 6th Street, 16th Street and Jefferson Street. ACHD, with the passage of the CIP update in 2006, identified more roadways that would remain in their current configuration despite projected congestion. These were 36th Street from State to Hill and Hill Road. Additional roadways were identified as preservation only, indicating that impacts fees for widening would be collected only for corridor preservation, not construction. These were Overland Road and Franklin Road (which showed the need for 7 lanes), and Ustick from Cole to Curtis (which showed the need for 5 lanes).

Physically Constrained

Meaning there is no more room to build because of various factors (limited right-of-way, developed land use, topography).

Meaning the character of the area would be significantly compromised.

Downtown Constraint

Meaning that the system is complete in a downtown area and expansion would compromise development potential and erode pedestrian level of service.

Defining Level-Of-Service

Roadway Level of Service. This is a measure of roadway congestion ranging from… LOS A--least congested -- to LOS F--most congested. LOS is one of the most common terms used to describe how "good" or how "bad" traffic is projected to be. LOS serves as a benchmark to determine whether new development will comply with an existing LOS or if it will exceed the preferred or adopted LOS. Typical Policy Threshold: LOS D
