Capital Projects Engineering Survey Section
The City of Santa Rosa's Survey Section is a part of Capital Projects Engineering of the Transportation and Public Works Department. The Survey Section performs topographic mapping and construction surveys as well as boundary and control surveys for the design and construction of the City's Capital Improvement Projects. These projects include street widenings and reconstructions, sidewalks, traffic signals, street lights, storm drains as well as sewer and water lines. Additionally, the Capital Projects Engineering Survey Section supports the City Right of Way Agent as well as other City Departments.
The Survey Section is also responsible for the maintenance and expansion of the City's Horizontal and Vertical Control Networks.
The Survey Section maintains a GPS reference base station which is located at our offices at 69 Stony Circle. This station is an NGS sanctioned Continuously Operating Reference Station (CORS). The CORS designation for this station is CASR. Data and information for this site as well as the NGS CORS network can be obtained on-line from the NGS CORS web site.
Horizontal and Vertical Control Networks
Vertical Control Network
The City of Santa Rosa's Vertical Control Network is based on the National Geodetic Vertical Datum of 1929 (NGVD 29). There are over 1300 benchmarks located throughout the city as well as the surrounding area.
This system is adjusted to USC&GS (now the NGS) Bench Marks in the area.
Data for City of Santa Rosa Bench Marks can be obtained through the City's GIS System.
