Provide intersection grading details for ALL intersections depicting the roadway crown transitions to meet the through streets. (STA & EL at EOA or FL at 25' even stationing 1+25, 1+50, ....). applicable LP's and inlets need to be included within these details as well as as through street slopes, PCR's, and FLPI's. Ramp/sidewalk elevations are recommended on these details as well. (The standard midblock or similar ramp needs approx 7.5'+ in length to meet ADA grades. That also does not account for the 2%-5% slope in the tree lawns which only adds to the length. In order to meet ADA, sufficient ramp lengths need to be provided, but where tyeing into a detached sidewalk for example that would limit the ability to lengthen a ramp thus required further evaluation of the top of ramp within the confines and the elevations/slopes of the sidewalk behind the ramp. If, as typically done in residential construction, the sidewalk is poured continuously and based on the typical rise behind the curb, this makes meeting ADA not possible without requiring removal of part of the sidewalk to depress it. The information provided in the plans should allow for proper construction in the beginning and if a general detail is not sufficient to achieve this, and it is necessary that the plans provide the supplemental information. Hence the comment and the discussion at the review of the comments flowing the 1st submittal. This issue/comment has not been addressed in the resubmittal - TYP) Additional curb return information may be provided as an alternative to curb return profiles (i.e. defined spot elevations and slopes with % between elevations based on the FL distance between points) Verify assumptions made regarding drainage flow routing. Consider roadway capacity at curb returns and the impacts of the grade transitions from the typical sections (These details to represent actual pavement grades resulting from typical paving practices. The CL STA/EL are critical to define along with corresponding C&G or EOA to determining the extend and acceptable slopes of transitions to be followed in the field via blue-topping)

Example: Hudson (FL+2")-(1.92%*20)=59.34 To ramp pan lip at 58.47 (6% x-slope in pan at ramps) Diff over 6' is 14% slope in front of ramp. By transitioning crown to meet through street at more reasonable rate and adjusting R & L FL to correspond, slopes like this can be greatly minimized where there are small to modest roadway grades on through streets.

The truck apron associated mountable C&G should generally reflect depths and reinforcement...this is not just a median it is a round-about island and is to be design to handle the potential traffic loading of larger vehicles and trailers, Further the engineer was to coordinate with the City on the design. Neither have been done. ) Provide a separate exhibit showing turning templates in, out and through the roundabout (all legs) for a WB-50 (Not provided with CD re- submittal) Identify/define LP's, HP's, grade breaks, etc. Turn off sight triangles in details for plan clarity (TYP)
