Dear Mr. Nolthenius,
The Contra Costa Area Office of the California Highway Patrol recently received a “Notice of Preparation” environmental document for the proposed Vineyards at Deer Creek Project- State Clearing House (SCH) #2019049008. After our review, we have concerns with the potential impact this project could have on traffic congestion and service delivery.
Our concerns relate to the proposed construction of up to 2,400 high density residential units on 555 acres with an additional 20 acres of commercial space and 20 acres of Community recreation space. This project is located in close proximity to State Route 4 (SR-4) which serves as an artery for the City of Brentwood and the greater region for vehicles traveling to and from the central Bay Area. This location consists of a single lane of travel in both the eastbound and westbound direction. SR-4 increases to just two lanes of travel in each direction just west ofCHP Comments on NOP
Balfour Rd, and remains a single lane in each direction east of Balfour Rd. This current configuration appears to not have the capacity to accommodate the expected increase in vehicular traffic. Additionally, SR-4 already experiences a significant amount of collisions due,
in large part, to congested traffic. The Contra Costa Area would strong} y re-commend this project incorporate infrastructure improvements which would increase the vehicular volume capacity of SR-4. Without substantial infrastructure upgrades this project could have a negative impact on our operations due to the increased traffic congestion; which could lead to a potential increase in traffic collisions, increased response times, delays in emergency services; and a negative impact to the safe movement of people, services, and commerce within our jurisdiction. Should you have any questions or need any additional information, please feel free to contact Lieutenant Knopf, of this command, directly at (925) 646-4980.
