B. 
Street shall have no more than two lanes (one in each direction).
C. 
The street shall have a regulatory speed limit of 25 mph or less.

G. 
The maximum grade of the street shall be 8%.
H. 
A traffic study will be performed by the Township. This study must find a speeding problem of at least 11 mph over the posted speed limit as the 85th percentile speed. Results of the neighborhood traffic study will be presented along with a presentation on speed humps to the homeowners.
A. 
Via informal petition, or a letter from an officer of an organized homeowner group, the homeowners of a neighborhood may request that their neighborhood be studied for the speed hump program. This letter or petition must represent a substantial percentage of the homeowners in that neighborhood.
B. 
By way of formal petition, at least 70% of the property owners requesting the installation of speed humps. The matter will be placed on the agenda for the next meeting of the Board of Supervisors and a hearing will be held and the petition will be approved or disapproved.

As a part of the formal petition, the homeowners' association requesting the installation of the speed humps shall agree to be responsible for 50% of the cost thereof. The homeowners' association contribution shall be deposited with the Township prior to the installation of the speed humps.

If the Board of Supervisors approve the requested speed hump or humps, they will be installed within six months' time.
The geometric design of the speed humps has been proven to be a critical factor in their effectiveness. Based on extensive research, speed humps will be constructed to adhere with the following specifications:
