The signs will be installed as Temporary signs the color (Orange/White) have been added to the plans. Need to specify color to be used for stripes. Closures that may be in place for extended periods need to use red and white stripes instead of the standard orange and white stripes. Please note on the plans which color is being used.

Size of the sign blade will depend on the required text hight for the primary legend. Text height is dictated by the posted speed limit. See table in Section 704.4.G of the Thornton Specifications. Major movement is on Eudora, not 146th. Eliminate cross pans and stop condition on Eudora A street sign sizing table was added to the plans to specify height of text and plaque size TYP - The text height for the street name type appears to be too small. See FHWA Standard Highway Signs book Figure D3-1, Sheet 1 of 3 for ratio of sizes to use between principal legend and street name type. A street sign sizing table was added to the plans to specify height of text and plaque size TYPICAL: Delete directional prefix from all street name signs. Also, delete all periods. roundabout striping starts where (TYP) All signs to be mixed case lettering Specify sign and font sizes on plans for local, collector, and arterial (Typical) - Add notes Street light missing on this corner TYPICAL:30 MPH for minor collector, Fairfax. not 25MPH.

Updated There is no park access roadway to be constructed points beyond the limit of along full limits of the park's the phase I work. Phase 1. Revise to show Viewport has been widened to show the limits of the park construction. Emergency access signs and barricades have been added/revised. Need signs indicating this is an emergency access only. Need to provide a means of preventing use by general traffic this is more than signs, but is still acceptable to the fire department. raised intersection signs have been modified Move barricades to north end with temporary turn around revise for correct speed control signing General use will not be permitted at this access. See Quail Valley's York Street fire access for an example. Sign Removed barricades have been removed at the intersection, as directed on the previous comments. Remove stop sign. It is not needed if access is for emergency use only. Stop sign will encourage general use.
callout removed continue double yellow to tie into existing DYCL extended to existing striped median The stop condition must be for the minor street. For this intersection, more traffic is likely to be going east-west than north-south so the stop condition should be for north-south traffic. W14-1a is missing. Dead end sign added W14-1 is missing. (W14-1a shown) Dead end sign added The stop condition has been modified so that the stop condition is northsouth traffic. 14, not 6 bike lane shift is not acceptable. Drop right turn lane should be offset enough so that no adjustment is needed to the alignment of the bike lane. The signs and markings for the the Fairfax Dr & E. 144th Ave intersection has been revised per comments and MUTCD. Eliminate crosswalks and stop bars from arterial intersections. (Modified striping plans will be required as part signal plans and they will go in with the signal) revise per detail 700-17 This sign was not added here, as it is placed after R2-1 is a "Reduce Speed Sign" missing. 19 Have outside lane terminate in right turn lane to eliminate double merge west of Fairfax.

Station offset included N&E is not something the that signing and striping contractor can figure anything from. Provide based on CL and any additional dimensions to aid in the proper field layout. (Also provide CL & CL stationing and roadways dimensions to aid in contractor layout) Station offset included marking locations (TYP) see next SS06 for additional comments regarding LF turn lane Delete the straight arrow pavement markings from bike lanes Close off end of striped median with radius. Define limits and provide radius. Stripe out the outside left turn lane (for ultimate, but not needed at this time per the traffic report). 67 ft 67 ft 144th Avenue needs to have the stop condition (until signal is installed). An additional stop sign is needed in the median due to the width of the intersection. minmin 100' 100' Double arrow warning sign is missing.

L=W*S=12*45=540 provide 12' lanes, including turn lanes (measured to FL), with 4' stripped bike lane. Maintain north median and outside curb lines at std. OS except at transitions for rt turn lanes. Eleliminate any shifts in bike lane at intersection.total width 64' FL-FL at intersection (w/ rt & left turn lanes) modified travel lanes 100 ft 540 ft Lane widths have been aligned and modified to meet requirements shown on City of Thornton detail 500-1 eliminate median and north C&G shifts min 12' 6' Show CL/Section line & roadway CL stationing 6' 12' 12' 24 ft 12' Width callouts were added travel lane and median widths have been added L what is going on here.
