Civilman72, thanks for the report you posted that is exactly what I was looking for. It was a huge help. msquared48, tell me about it.

I understand that there is an issue here with the parking lot but what I'm really looking for are standards that have not been met. Specifically for lighting or trip hazards. I'm not sure if these standards exist and was hoping to find out more.

Thanks civilman72. The asphalt is anywhere from 2-6" above the field elevation. It could be perceived as a trip hazard. Can you point me to any references/standards that would be in effect for trip hazards?

A citizen had an accident at a town owned parking lot. A pedestrian was outside of the asphalt in the grass at dusk and when they walked back to the parking lot they tripped over the edge of the asphalt and injured themselves. There is no curb or painted edge along the asphalt lot, there is...

What kind of clear zone guidlines are there for roadside seating at a cafe? We have a 25mph posted speed limit with vertical curb face with a 12' sidewalk on the back of curb. Can we have seating on the 12' sidewalk? AASHTO says to keep a minimum of 18" from the face of the curb for clear...

Bimr, do you have any links for a system like that? Haven't heard of a low pressure grinder pump.

I don't think the syphon would work since there won't be a constant flow. I'm thinking the gravity to a mini pumpstation would be best. Do any of you have any suggestions for a mini-pumpstation?

I could, but an 8" gravity line would cost a lot more than a 2" FM. Plus the gravity line would require expensive manholes. The site is remote and the pipeline will be more like a long service since no one in the future will tie into it.

The sketch shows a gravity line for sewer. That was before it was determined impossible to gravity under the stream and tie into the manhole.

I'm designing a small pavilion site with a parking lot and bathroom in a remote part of my town. The site is located on top of a hill. At the bottom of the hill there is a stream and on the other side of the stream is the sewer manhole I will be tying into. I was planning on using a grinder...

Thanks guys, seems like maybe I should leave it to the experts. :( Was looking forward to CADing up some nice straight lines for a change.

I am currently the in-house design engineer for a small town. We are designing a boardwalk in an environmentally sensitive area. I've been working as a land development engineer for the past 8 years but I have little structural design experience besides what I learned in school so many years...

The minimum crosswalk width in North Carolina is 6'. Does anyone know if the ADA has any requirements of minimum crosswalk width?

My town is having issues with median signs getting hit by motorists. These are the bear right signs that are placed at the nose of medians to alert drivers of the median. I need to research ways to decrease the danger and frequency of these collisions. So far I've come up with the following...

I received a complaint about one of my town's center left turn lanes (both directions use the center lane for left turns). A homeowner has complained about almost getting into a head on collision with another motorist trying to make a left turn going westbound as the homeowner was traveling...
