Capabilities

Every discipline your site needs — coordinated under one PE seal.

Ten engineering service areas in-house, built around RV parks and resorts, so every system is designed together instead of stitched across firms.

01 — Civil & Site

Civil & Site Development

The grading, drainage, and site backbone of your project — designed to pass AHJ and drainage-district review without a redline marathon.

  • Drainage & detentionHydrology and hydraulics, detention sizing, and outfall design (HydroCAD, HEC-RAS, HEC-HMS), including HCFCD and HCED outfalls.
  • Grading, paving & plattingEarthwork, site grading, pavement sections, and engineering support for plats (Civil 3D).
  • Permit application & acquisitionApplications prepared, submitted, and carried through agency comments to approval.
Civil site infrastructure

02 — Underground Utilities

Underground Utilities

All underground utilities, wet and dry, designed together so they miss each other in the field instead of on a change order.

  • Wet & dry utility designWater, sanitary and storm sewer, gas, electric, and telecom — routing, depth, and conflict resolution.
  • Site power distributionService, distribution, and pedestal layout sized for full occupancy.
  • Coordinated, not sequentialUtilities developed against the grading and structural set, not bolted on after it.
Utility plans

03 — Structural

Structural Engineering

Foundations and framing designed for Texas soils and wind — sealed, efficient, and constructible.

  • FoundationsSlab-on-grade, pier-and-beam, and masonry pier design for expansive soils.
  • Framing & analysisWood, steel, and concrete framing modeled in Robot Structural Analysis.
  • Retaining & site structuresWalls, ramps, and miscellaneous structures for site build-out.

04 — OSSF

On-Site Sewage Facilities

On-site wastewater for sites beyond the reach of municipal sewer — evaluated, sized, designed, and permitted.

  • Site evaluations & soil assessmentsSoil profile and site suitability work that sets the design basis.
  • System designConventional septic, ATU, aerobic drip, and mound systems sized to soil and flow.
  • 30 TAC Chapter 285 permittingPermit packages prepared for the county AHJ, including Harris County (HCED).
  • Installation inspection & as-builtsField inspection and as-built documentation to close the permit.

05 — Water Systems

Water Systems

Water supply for rural and resort sites — source, storage, and distribution engineered and submitted to the state.

  • Public water systems (PWS)PWS design and TCEQ engineering reports.
  • Hydropneumatic tanksTank sizing and design reports for pressure-maintenance systems.
  • Supply planningSource capacity, storage, and distribution for rural and resort sites.
Water system infrastructure

06 — Environmental & Regulatory

Environmental & Regulatory

Keeping your site compliant and defensible — floodplain, stormwater, and permitting handled before they become a schedule problem.

  • Floodplain & FEMAFloodplain analysis, finished-floor determination, and LOMA / LOMR support.
  • SWPPP & stormwaterStormwater pollution prevention plans and TPDES construction general permit compliance.
  • USACE & TCEQNationwide Permit applications and TCEQ environmental compliance.
Stream and floodplain

07 — Aquatics

Pool & Aquatic Design

Recreational water for resorts and amenities — engineered end to end, not handed to a pool contractor to figure out.

  • Structural & shell designPool and feature structures designed for soils, loads, and water pressure.
  • Hydraulics & circulationPumps, filtration, surge, and recirculation sized for bather load.
  • PermittingPublic-pool and health-department submittals handled.
Resort pool design

08 — Fire Protection

Fire Protection

Life-safety and suppression engineered into the building and site package — so the fire marshal and the AHJ both sign off.

  • Fire suppressionSuppression-system design for amenity and support buildings.
  • Fire-water supplyFire-flow demand, hydrant layout, and supply coordinated with the water system.
  • Life-safety & accessEgress and fire-lane access coordinated across the site.
Fire protection

09 — Fiber, Network & Security

Fiber, Network & Security

The connected backbone an RV park or resort runs on — fiber to every pad, reliable Wi-Fi, and the cameras and access control that protect guests and revenue.

  • Fiber-optic designGPON/FTTx architecture, split-ratio plan, optical power and loss budget, conduit and pathway design, and pad-level drops.
  • Wi-Fi & networkCoverage planning, switching, and IDF/MDF layout sized for full occupancy.
  • Security & access controlSurveillance coverage, gate and access control, and low-voltage coordination.

10 — Due Diligence

Land & Site Due Diligence

Know what a parcel can carry before the money is committed. We pull the records, read the site, and tell you what will and won't work.

  • Feasibility evaluationsWhat the parcel supports for your intended use — density, access, utilities, and the constraints that drive cost.
  • Parcel, FEMA & soils researchAppraisal-district records, FEMA flood mapping and base flood elevations, and NRCS soils, packaged into one picture.
  • Regulatory & AHJ reviewThe governing jurisdiction's requirements, drainage district, OSSF and water constraints, and the permitting path.
  • Development constraints memoA plain findings summary you can hand to a lender or partner.
