The City Council voted Tuesday night to instruct City Atty. Robert Myers to draft an emergency waste-water control ordinance.
The ordinance would limit projected increases in the city's annual waste-water flows resulting from new development projects that receive building permits after July 1.
The measure would restrict the city's total annual waste-water increase to no more than 1.36% or about 43,000 gallons per day.
It may also require any new development of more than 150,000 square feet to install an on-site waste-water treatment system. The council instructed its staff to examine the possibility of reducing the square footage requirement since few developments scheduled for construction within Santa Monica are that large.
