Conditions — as established by state law in order for communities to legally use radar — allow the City Council to lower the posted speed limit on four street segments in Manteca if they so choose.

The council on Tuesday when they meet at 6 p.m. could lower the speed on:

*Airport Way from Daisywood to the Union Pacific railroad tracks from 45 mph to 40 mph.

*Airport Way from Crom Street to the railroad tracks from 45 mph to 40 mph.

*Northbound Main Street from Woodward Avenue to Sedan Avenue from 45 mph to 40 mph. Southbound is already 40 mph.

*Northbound Union Road from Wawona Street to 400 feet of Sephos Street from 40 mph to 35 mph.

The required relook at conditions every five years that includes length and width of roadways, manual radar surveys, number of lanes and striping factors, nearby parks and schools, statistical data or vehicle speeds, and collision history also means speeds will need to be increased on the following streets in order for the city to continue using radar for speed enforcement:

*Wetmore Street from Main Street to Mellon Avenue will increase from 30 mph to 35 mph.

*Eastbound Atherton Drive from Union Road to Airport Way will increase from 35 mph to 45 mph. Much of westbound Atherton is already 45 mph.

The same criteria is used to establish allowed speeds on roads that the city would like to be able to use radar for speed enforcement.

*Mono Street from Pillsbury Road to Springfield Drive, 25 mph.

*Oleander Avenue from 775 feet south of Sephos Street to Red Pheasant Lane, 25 mph.

*Woodward Avenue from Airport Way to McKinley Avenue, 35 mph.

*Woodward Avenue from McKinley Avenue to South Woodward Avenue (where it turns at a 90 degree angle and heads south), 45 mph.

The other 96 street segments surveyed to allow the legal use of radar to continue will not see speed limits changed.

The state requires a registered traffic engineer to evaluate roadway conditions and newly constructed roadways to set posted speeds.

That, along with police officers that issue speeding citations having special training, allows cities to go seven years before having to redo radar speed surveys.
