“Cityscmurrieta’s runoff model for our watershed study was the most accurate we’ve seen. Their calibration with local gauge data cut our flood risk uncertainty by a third.”
David Tran
Senior Hydrologist, Pacific Watershed Group
“The gravity-fed trench network they designed eliminated street ponding during a 10-year storm. No pumps, no maintenance — exactly what our neighborhood needed.”
Maria Castillo
Public Works Director, City of Mesa Verde
“Their topographical profiling with total stations caught a subtle ridge that would have caused backflow in our culvert design. Saved us months of rework.”

Why work with us
Every service is built around real engineering constraints — not promises. Here is what you can expect.
Gravity-fed trench networks designed for your catchment area reduce street ponding during a 10-year storm event. No pumps, no power — just precise slope calculations and aggregate sizing.
Optical total station surveys catch subtle ridges and depressions that drone or LiDAR surveys miss. This prevents backflow and rework on culvert and channel alignments.
SCS curve number and 2D hydraulic models calibrated with local rain gauge data improve flood prediction reliability. You get a design that matches real watershed behavior.
Minimum velocity calculations keep sediment from settling inside the network. Less maintenance, longer service life, and consistent hydraulic performance year after year.
Every recommendation comes from on-site experience — outlet protection, alignment tolerances, catch basin placement. No generic textbook answers.
You receive survey reports, model outputs, and design summaries that engineers and reviewers can actually use. No fluff — just data and decisions.
