N/B Brentwood Blvd. approaching Oak St. is a two lane highway. About one block prior to Oak St., it becomes a four lane highway. This section is posted at 35 mph. Shortly after it becomes four lanes, the speed limit is reduced to 25 mph. This is two blocks prior to a right curve in the roadway that has large yellow and black warnings to slow to 15 mph while negotiating the curve. A 35 mph speed limit is safe on this four laned two block portion along with the 15 mph warning for the curve. The addition of the 25 mph speed limit to slow traffic prior to the curve is totally unnecessary, and can only be considered as a revenue generator. There are sidewalks on both sides, and a crosswalk at the signalized intersection of Brentwood Blvd. and Oak St. Pedestrian traffic is light to none with no enticements for jaywalking.
