max street slopes
(OP)
We are designing a subdivision road (speed limit 25 mph). The local standards allow up to 15% max grade but I am uncomfortable going above 12. no reason to be nervous but i have always used 12 as a rule of thumb. any insight would be appreciated.





RE: max street slopes
However having a heavy grade on the road can save you having to need a "slow point" in the road. Because people are not going to fly down the grade and they are not flying up it either.
Be careful when you flatten off the grades to. most local stds. have a maximum VC radius and you may have a problem with sight distance at the crest.
Do you have to bench you pads along side the road. Seems you have some steep terrain there. If you have to cut into the hill to have benched pads, maybe your road can be pushed down to 12%.
Then all you have to worry about is balancing your earthworks ! and I know how fun that is :)
Hope this helps

I know trucks are not supposed to frequent a residential neighbourhood, but for disabled people and people whom require special deliveries via trucks (oxygen bottles, propane, etc) the steeper slopes increase the probability of a serious accident.
