| 02/11/2021 | ZELIN CANCHOLA | DOT TRAFFIC | REVIEW | Reqs Change | DTM comments on the Offsite Improvement Plans for Project Merlin (Corona Rd, Los Reales Rd, Alvernon Way) project: - Sheet 1: Under "WORK TO BE DONE", Std Dtls 2 & 3 refer to the old pavement marking and signing manuals. As of December 2020, the joint PC/COT Signing and Pavement Marking manuals have now been combined, so wherever referenced, we should probably refer to the new joint "PC/COT Signing & Pavement Marking Manual" (Typical). If needed, the consultant can refer to the new manual at https://webcms.pima.gov/UserFiles/Servers/Server_6/File/Government/Transportation/Roadway%20Design/FINAL-Pima-County_City-of-Tucson-Signing-and-Pavement-Marking-Manual-2020-First-Edition_linking_nocomments-12_21.pdf 1- Sheet 2 & Throughout, Callout 12: Is there room for a 6' wide sidewalk instead of 5' as called out? 6' is preferred, if possible. 2- Sheets 6-8, Multi-Use Path: Taking ADA considerations into place, does the multi-use path along Alvernon need to contain so many curves in the alignment? A potential blind user may have difficulties navigating this pathway. 3- Sheet 9: Pavement arrow and legend markings should be placed per Sheet 3.2.4 of new joint Signing & Marking Manual. (Typical) 4- Sheet 9, Tapers: Are left turn bay taper lengths substandard when compared to Appendix A of the Signing & Marking Manual? It appears so. (Manual calls for T = W*S for speeds of 45 mph or greater for left turn lane tapers.) 5- Sheet 9 & 10, Corona: Lane widths of 21' called out on Corona are rather wide. Consider placing a WS6 edge stripe for a bike lane. 6- Sheet 11, Multi-use path: Recommend placing a YG4 (3x9) centerline stripe for multi-use path, considering it is 12 feet wide. 7- Sheet 12, Signing Note 1: Please remove reference to 2002 signing manual and refer to new joint PC/COT Signing & Pavement Marking Manual. 8- Sheet 12, PM Note 1: Please change reference from TDOT PM Manual to new joint PC/COT Signing & Pavement Marking Manual. Thank you, Greg Orsini, P.E. Greg.Orsini@tucsonaz.gov |

It is the owner responsibility to keep a 5' wide (minimum) by 7' tall clear pedestrian access open across the entire property. 3.
