    Measuring/Designing Curb Ramp Slopes

    Geopavetraffic I think I know what you are explaining. What I envision you explain however will expose building foundations OR not provide the minimum "passing" space for peds at the ramps. I may be thinking the wrong thing though. I am probing for that breakthrough idea lol. Using your...

    Measuring/Designing Curb Ramp Slopes

    Of course ADAAG applies to sidewalks but it was developed with vertical structures on level surfaces in mind - that's how PROWAC came to be. I am not trying to convince anyone to join my battle, just want to know who is really dealing with this in an urban setting. I deal equally with State...

    Back-in vs. Pull-in Parking - which is better?

    I would LOVE to see data on this. Maybe I will initiate a study here in Baltimore City. A few years ago, I had proposed reverse angular parking along a road that had existing front-end angular parking in a commercial district. Existing Speeds were posted at 30 mph, 2 lanes each direction with...

    Measuring/Designing Curb Ramp Slopes

    PROWAC is in the draft phase and is addressing this very issue in the final. I think many engineers/designers do not realize it's a draft. I just recently learned this myself within the past few months by communications with the access board itself. In Baltimore, we have a variable terrain...

    Measuring/Designing Curb Ramp Slopes

    This is an excerpt from a memo penned here at the city: ADA Standards for Accessible Design 28 CFR part 36 Sections 4.1.6 and 4.7 require running and flare slopes of 1:10 in existing facilities and 1:12 in new construction. Transitions from ramps to walks, gutters, or streets shall be flush...

    Changed Drawings????

    I do not believe you are liable UNLESS - for some crazy unprecedented reason, the contract you entered has a clause which says you allow someone to change your drawings. Now who would do that? But yes, it happens frequently, and the evil architects are always behind it :-b

    Roadway Cross-sections

    In my region we show EVERYTHING - it is especially important in urban areas. I deal with mostly reconstruction and that often includes utility work. Showing all of the underground and surface features is RELATIVELY simple with today's engineering software. It requires a lot of "upfront" data...

    Measuring/Designing Curb Ramp Slopes

    I have been working over the past few years developing ADA standards within the right-of-way. I am curious to get a feel for how anyone (IF ANYONE) interprets the 12:1 runnng slope for a pedestrian curb ramp. MD SHA and The City of Baltimore have interpreted "12:1 requirement" to mean "a...

    Curb Inlet Protection

    I need more info about the project. Is the project urban or rural? Do you have a concept?

    Rehabilitating Rigid Pavement Roadways

    Could anyone share what methods you are currently using for rigid pavement rehab? I am looking for newer lower cost ways to rehab a major downtown rigid roadway in Baltimore City. Just trying to get a feel for what other DOTs are using as their approach.

    ADA Compliance -- Sec.36.403 Alterations: Path of travel

    I work for the DOT in Baltimore, MD. I have a question regarding the need for ADA compliance based upon the following situation: An existing roadway is to be streetscaped and resurfaced. Building Faces extend to the ROW. The existing cross-slope on one of the sidewalks is at least 8% from...
