CSLB Land Development Engineering case studies
CSLB Land Development Engineering · Put your knowledge to work in context.
Land development engineering sits at the intersection of civil design and the entitlement process: taking a raw or underused parcel and turning it into a buildable, serviced, code-compliant site. This exam-style credential is aimed at civil engineers, land planners, project engineers, and construction professionals who work on subdivisions, commercial pads, and mixed-use infill, and who need to demonstrate command of the full development sequence rather than a single specialty. The CSLB Land Development Engineering case studies are 5 cases and about 2,864 words.
1Downstream Culvert Surcharge on an Infill Lot
A developer proposes a 14-lot subdivision on a 3.2-acre parcel. The site currently drains as sheet flow to a 36-inch CMP culvert crossing the county road at the low corner; the culvert invert is 2.1 ft below the road shoulder and the pipe is estimated at 40% full during the 10-year storm.

A 2,000-ft, 12-inch ductile iron water main loops a new hillside neighborhood to an existing 12-inch main at the bottom of the hill. The existing main has a pressure of 72 psi at the connection under peak-hour demand, and the static pressure at the connection is 95 psi.

A proposed 1,100-ft residential collector street climbs a 6% grade and ends in a T-intersection with an existing arterial. The vertical curve at the crest of the collector is a 300-ft sag/crest combination; the crest has a K-value of 90 for a 30-mph design speed.
