Traffic Noise

After extensive public outreach and one-on-one meetings with neighborhoods and property owners, several proposed noise walls were eliminated. However, a few walls along Linda Vista Boulevard will be built in late 2009. To find out more about the proposed noise walls and their selected locations, please contact Kimberly Gale at 885-9009.

In efforts to curb noise levels, Twin Peaks Road west to Silverbell Road will be resurfaced with rubberized asphalt concrete. Roadway resurfacing will improve drivability of the roadway and decrease the noise from vehicle tires.

Cultural Resources

The cultural resources inventory report prepared for the project recommended mitigation of impacts to two National Register of Historic Places-eligible properties within the project area. Mitigation will involve collecting and documenting information on one site and developing and implementing a pre-construction testing plan for the other site. Test pits will be excavated to determine if significant buried archaeological deposits are within the construction area. The testing program will likely require backhoes and other light excavating equipment.

Clean Water Act Section 404 Permitting

The twin bridges spanning the Santa Cruz River, the widening of the low flow channel in the Santa Cruz River, the redirection of a wash at the intersection of Twin Peaks Road and Camino de Mañana, and wash crossings of Linda Vista Boulevard would impact Waters of the U.S. As a result, a permit under Section 404 of the Clean Water Act and water quality certification under Section 401 of the Act will be required.
