City Surveyor, City of Grass Valley, Nevada County
NorthStar has been the acting City Surveyor since January 2013. Mike Mays, PLS, Survey Department Manager, has provided map checking and technical review for subdivision maps, parcel maps, lot line adjustments, public roadway dedications and vacations, and city lease parcels. The complexities of checking and approving work of other professional surveyors and engineers are in adapting to regional practices and local policies. These are overcome by maintaining clear and open lines of communication with City Staff and with the surveyor/engineer, in addition to having a thorough understanding of local ordinance.
South Feather Water and Power Agency
NorthStar provides on-call professional surveying services in support of the Agency’s Power Division and Water Division operations. In addition, they provide annual and biennial surveys for deflection and deformation monitoring of Ponderosa, Miners Ranch, Little Grass Valley, Sly Creek and Lost Creek Dams; and biannual monitoring for the Woodleaf Power house penstock. Services provided include: GPS and terrestrial control surveys; topographic surveys; boundary survey; construction surveys for dam rehabilitation; and vertical control gauging stating surveys. One of the intricacies involved with dam monitoring is ensuring good, comparable results with each monitoring epoch. We maintain over a decade’s worth of results and we must be confident that we are comparing “apples to apples” when reviewing new data. This is done by maintaining standard, repeatable procedures for each monitoring epoch. Furthermore, the monitoring surveys are performed at the same general time each year with the goal of having similar environmental conditions.
