What JLC Engineering & Consulting does

JLC Engineering & Consulting Inc. is a privately held civil engineering consulting firm founded in 2006 by Joseph L. Castaneda, PE, and headquartered in Murrieta, California. The firm specializes in hydrology, hydraulics, stormwater management, and flood control engineering, serving land developers, municipalities, and utilities across Riverside County and Southern California. Its service portfolio spans four interconnected practice areas: Engineering Planning (entitlement, preliminary drainage studies, master drainage plans), Final Engineering (storm drain design, FEMA CLOMR/LOMR revisions, detention basin design, water quality management plans), Municipal Engineering (roadway design, construction inspections, post-construction BMPs), and Stormwater and Watershed Modeling (hydrology studies, 1D and 2D HEC-RAS modeling, scour analyses).

The firm executes projects using established industry tools rather than proprietary technology, including HEC-RAS 1D and 2D for hydraulic modeling, WSPG for storm drain capacity analysis, and the Rational and Unit Hydrograph methods for hydrology per RCFC&WCD guidelines. Documented project work includes a floodplain evaluation for Southern California Edison's Valley Substation in Menifee, a 570-acre storm drain system design for the City of Beaumont's Line 16 project, and a 120-acre, 446-lot hydrology and hydraulic analysis for the Canterwood residential development, incorporating seven bioretention basins for water quality treatment.

Revenue is generated through professional services fees on project-based engagements, with pricing delivered via direct quote rather than published rate cards. The firm operates with a core technical team of approximately four engineers (a 28-year veteran PE founder, his Stanford M.S.-credentialed son, a 20-year land development specialist, and two Cal Poly Pomona alumni) plus an office manager. The company is family-owned, has no outside investors, and has remained regionally focused since incorporation.

Direct peers

• Psomas: California-based civil engineering and surveying consulting firm serving land developers, municipalities, and utilities across the Western U.S. Highly comparable to JLC in service mix (civil engineering, hydrology/hydraulics, land development) but at significantly larger scale.
• Dokken Engineering: California civil engineering firm with strong hydrology, hydraulics, and stormwater capabilities serving municipalities and developers. Comparable to JLC in technical specialization and client base.
• Fuscoe Engineering: Southern California civil engineering firm specializing in land development, hydrology, stormwater management, and municipal engineering. Closest direct peer given its regional focus and overlapping service portfolio with JLC.

Broad incumbents

• Tetra Tech: Global consulting and engineering firm with deep water resources and environmental practices. Competes with JLC on stormwater modeling and FEMA floodplain work but at vastly larger scale.
• Stantec: Global engineering, architecture, and environmental firm with significant Southern California operations in water and civil engineering. Overlaps with JLC's hydrology and stormwater services for larger programs.
• AECOM: Premier global infrastructure consulting firm with major Southern California presence and large water resources practice. Competes with JLC for major municipal and utility engineering programs.
• Kimley-Horn: Top-tier national engineering consultancy with strong land development and water resources practices across California. Provides JLC direct competition for developer and municipal clients in the Inland Empire.
• Michael Baker International: Large national engineering consultancy with strong water resources, stormwater, and FEMA floodplain practice. Competes with JLC for larger municipal and federal contracts while offering broader service lines.

Regional players

• K&A Engineering: Smaller civil and water resources engineering firm with comparable specialty services. Similar size profile to JLC and similar focus on regional stormwater and municipal work.
• DSA Engineering: Southern California-based civil engineering consultancy serving municipalities and developers. Comparable scale and service overlap with JLC, particularly in land development and drainage design.
