Improvement Permitting Process

CALCBS works hand in hand with Civil Engineers and other Design Development professionals to insure a smooth and efficient permitting process. Our working relationships with most municipalities, coupled with our expertise, create the smooth path necessary to maneuver thru the process to insure that our clients permits are processed as efficiently as possible. The permitting process includes permits for:

Grading Permits

Any alteration of the site requiring moving more than 50 yards of soil

Encroachment Permits

Extension of or connection to existing facilities (sewer, water, storm, streets) triggers the need for an Encroachment permit and the knowledge and experience to know which departments to work with to secure them.


Army Corp of Engineers permits required when working in proximity of navigable waterways.  This includes seasonal creeks and drainage channels.


Storm Water Pollution Prevention Plans/National Pollutant Discharge Elimination System. Oversight for preparation of plans by a Registered Civil Engineer’s and other required professionals, processing permits thru the appropriate and required governing agencies and recommendations for proper installation and monitoring of required measures.
