Draft Screening Process • Level One Fatal Flaw Analysis
– Pass/Fail • Would not pass this level if:
– Does not meet the Purpose and Need – Is untested for the intended purpose – Is unacceptable to a large number of
stakeholders – The capital or operations/maintenance costs
exceed the project budget
![Page 16: 16th Street Mall - RTD Bus & Rail...2015/08/21 · Mall was designed by I.M. Pei and Associates and was opened in 1982 16th Street Mall Description – Pedestrian and transit mall](https://reader033.vdocuments.net/reader033/viewer/2022052923/5f04178c7e708231d40c47aa/html5/thumbnails/16.jpg)
Draft Screening Process • Level Two Detailed Analysis
– Quantify to the extent possible • Alternatives would be measured against
the following criteria: – Safety – Aesthetics – Maintenance Frequency – Capital Cost – Maintenance Cost – Stakeholder Support
![Page 17: 16th Street Mall - RTD Bus & Rail...2015/08/21 · Mall was designed by I.M. Pei and Associates and was opened in 1982 16th Street Mall Description – Pedestrian and transit mall](https://reader033.vdocuments.net/reader033/viewer/2022052923/5f04178c7e708231d40c47aa/html5/thumbnails/17.jpg)
