Water Resources Engineering in Midland, TX
Hydrology, stormwater management, drainage design, and floodplain analysis for municipalities, TxDOT, and land development projects across the Permian Basin. Certified Floodplain Manager on staff.
Engineering Solutions for Stormwater, Drainage & Flood Risk
Magrym Consulting provides water resources engineering services that help municipalities, developers, and transportation agencies manage stormwater runoff, design drainage infrastructure, and navigate floodplain regulations. Our team includes a Certified Floodplain Manager (CFM) with direct experience in FEMA flood studies and LOMR/CLOMR applications.
From rainfall-runoff modeling and detention pond design to erosion control plans and water distribution systems, our water resources work integrates with our civil engineering, land surveying, and environmental services — giving you a single team from site assessment through construction.

Our Water Resources Process
From watershed analysis to construction-phase compliance — we keep your project moving and permitted.
Site & Watershed Assessment
We evaluate existing conditions, review floodplain data, and collect topographic survey data to define your project’s drainage requirements and regulatory constraints.
Hydrologic & Hydraulic Modeling
Our engineers build rainfall-runoff and hydraulic models to size drainage infrastructure, evaluate flood risk, and design detention or retention facilities.
Design & Permitting
We produce PE-sealed drainage plans, SWPPP documents, and regulatory submittals — including FEMA LOMR/CLOMR applications and TCEQ stormwater permits.
Construction Support
Our team provides construction-phase inspection, BMP monitoring, and materials testing to ensure drainage infrastructure is built to spec and permit-compliant.
Frequently Asked Questions
Magrym Consulting provides hydrology and hydraulics studies, stormwater management, drainage design, floodplain analysis, erosion and sediment control plans, and water/wastewater system design. Our licensed PE engineers and Certified Floodplain Manager handle projects from initial watershed assessment through construction support.
Yes. Claudius Sanchez Czyzewska, PE, CFM leads our water resources practice. His Certified Floodplain Manager credential means Magrym can prepare and submit FEMA flood studies, LOMR and CLOMR applications, and floodplain analysis reports directly — without third-party coordination delays.
Yes. Magrym Consulting develops Stormwater Pollution Prevention Plans and construction-phase erosion control designs that meet TCEQ and EPA requirements. We select appropriate BMPs, prepare permit documentation, and can provide construction-phase inspection and monitoring to maintain compliance throughout your project.
A LOMR (Letter of Map Revision) and CLOMR (Conditional Letter of Map Revision) are FEMA processes to revise official flood maps when conditions change. Magrym’s CFM-credentialed engineer prepares the hydraulic models, supporting documentation, and application packages required for FEMA review and approval.
Yes. Magrym Consulting provides in-house RPLS-licensed land surveying, so topographic data, cross-sections, and floodplain surveys feed directly into our hydrologic and hydraulic models. This eliminates third-party handoffs and ensures the accuracy that drainage design and FEMA submittals require.
