Pollution Prevention for Municipal Operations

The City of Lake Oswego conducts a variety of activities focused on the prevention of typical stormwater pollutants (sediment, hydrocarbons, trash and debris, nutrients, metals) from entering the MS4 system. Such activities include the maintenance and repair of City streets; the maintenance of public parks and recreational areas with the intent of minimizing fertilizer and pesticide use; the maintenance of municipal facilities; control of potential cross-connections from the sanitary sewer system; and master planning for stormwater quality improvement.
