Through the years Youngdahl has prepared a multitude of environmental reports (Phase I and Phase II Environmental Site Assessments), geologic, and geotechnical engineering studies for the infrastructure improvements as well as residential developments. As construction of the area progressed, Youngdahl provided a wide array of geotechnical consultation and testing services during the grading operations for construction of the building pads within the residential villages, arterial and interior roadways, neighborhood parks and golf course. Youngdahl also provided the geotechnical testing services during construction of all underground utilities and top side improvements associated with the major infrastructure and residential villages, working with the inspection staff of the City of Folsom to document that the contractor’s work was performed in accordance with the City’s design and construction standards. Development of such a large community also required an extensive network of infrastructure improvements inlcuding sewer lift stations, pump stations and potable water supply tanks. Through the course of development, Youngdahl provided all of the geologic and geotechnical design reports for these improvments and provided all of the geotechnical and special inspection services during their construction.
