In general, Speed Limits such as you mention are set by State Law.  

In Ohio, for example, the following rules apply:
	15 in alleys
	20 in School Zones
	55 on all rural roads except freeways (ie in Townships)
		On Township subdivision streets and dirt roads, the 
		trustees can, lower the limit to no less than 25
	25 on most streets in Cities and Villages, except: 
		35 on State Routes and through highways outside  
		business districts
	50 on controlled access roads and expressways
	55 or 65 on Freeways (complicated rules)

In Cities and Villages, the Council can request a lower limit by
petitioning the Director of the State DOT, stating an engineering study
for rationale.  They may RAISE a limit (up to 55) if conditions warrant
(like a 4 lane road through undeveloped land)
