- Why Challenger
A site grading survey shows the existing contours and site elevations along with any completed or proposed structures to ensure sufficient drainage on site. This plan ensures that during construction, surface drainage flows away from buildings and flooding issues are appropriately mitigated.
Several municipalities require a grading plan as part of their local permitting process. Their objective is to show where water is likely to drain and prevent damage to neighboring properties.
Upon completion of a project, our professional land surveyors issue a plan or grade certificate to confirm the elevations and grades on the site and that they comply with local regulations and standards.
