EXPERIENCE
Mr. McArthur has extensive experience in performing comprehensive surface and groundwater
management plans, hydrology and hydraulic analysis for large scale projects. He authored and directed
the “Hillsborough County Comprehensive Plan – Stormwater Management Element,” and was the first
private consulting engineer to sit on a Florida Department of Transportation Value Engineering Team
(VET.)
During Mr. McArthur’s 27 years of experience, he has managed complex civil/environmental projects from
planning through design, permitting and construction. Project sizes range from less than one acre to over
80 square miles and covers 23 states, three U.S. Territories, and four foreign countries.

REPRESENTATIVE PROJECTS
Cypress Creek Town Center – Pasco County – Developed a stormwater management plan and
addressed wetland impacts and mitigation. In addition to the standard stormwater treatment and
detention requirements, a detailed hydraulic analysis of Trout and Cypress Creek was undertaken to
address floodplain issues. The EPA SWMM v.4.316 EXTRAN block was used to model the creeks and
onsite wetlands/detention ponds. Permits obtained for SWFWMD, Pasco County and ACOE.
The Shops of Wesley Chapel – Pasco County – Design and permitting of the stormwater management
system for the regional mall located at the northwest corner of Interstate 75 and State Road 54.
International Mall – City of Tampa – Design and permitting of the stormwater management system for
the regional mall located adjacent to the airport.
Delaney Creek Update – Hillsborough County – The Hillsborough County Delaney Creek Stormwater
Management Model was updated for a 3 mile portion of Tributary ‘A’. The updates included the addition
of recent construction, issues permits, biological indicators, overbank storage and supplemental survey.
The updated model resulted in lowering the 100 year floodplain by 3.75 feet in some areas. The updated
model was approved by Hillsborough County and sent to FEMA for inclusion in the updated FIRM.
Wilkinson-Oconee Mitigation Bank Hydraulic Study – Wilkinson County, Georgia – Developed a
stormwater restoration management plan, construction plans, best management practices and
hydrodynamic stormwater model for a 7,000 acre wetland mitigation bank. The hydrologic/hydraulic
analysis of the mitigation site consisted of modeling the entire contributing watershed of over 20 square
miles. Interaction of various hydrologic components of this site, such as evaporation, seepage, velocities
and sediment transport were modeled on a continuous daily simulation basis for a 30-year period using
actual historical data. Permits for the ACOE were also obtained as part of the scope of services.
Cone Ranch Tiger Creek Floodplain Study – Hillsborough County – Prepared a hydrodynamic
backwater model to determine existing conditions 25 and 100 year floodplains for the Tiger Creek
watershed. The model was used to evaluate the potential of placing ditch checks within the drainage
system for wetland restoration, groundwater recharge and water conservation.
Hillsborough County Northwest Wetland Mitigation Bank – Project Manager in charge of production
of the stormwater models, permit preparation, construction plans, coordination and negotiation with the
regulatory agencies.
Hunter’s Green – consisting of 2,000 acres with an environmentally sensitive stream flowing through it:
the first project designed and permitted through the state where a created wetland was used for biological
treatment of runoff. The project was pilot project for the Florida Quality Development process.
Tampa Technology Park – 1,750 acre commercial development which uses biological treatment for
stormwater runoff and addresses floodplain development for Cypress and Trout Creek which pass
through the site.
Breckenridge West – 200 acre commercial development addressing the use of the 100-year floodplain
for all the stormwater attenuation.
Calusa Trace – 600 acre residential development that includes volume sensitive watersheds which
address the use of biological treatment in natural and created wetlands for the pollutant loads associated
with stormwater runoff.
L404 Wetland Mitigation Project for Disney World – at the time of permitting, this 79 acre wetland
creation project was the largest such wetland mitigation project approved by the State of Florida.
Citrus Park Town Center – Design and permitting of the stormwater management system plan for a 175
acre regional mall located in Northwest Hillsborough County.

State Road 580 – Bridge Hydraulics – Hillsborough County – design and permitting of the Bridge
Hydraulic Report (BHR) and Bridge Hydraulics Recommendation sheet (BHRS) for the crossing of
Channel C-1. The hydraulic analysis was performed using the HEC-1 and HEC-2 computer models, in
accordance with the latest requirements of FHWA and FDOT. Scour analysis was performed using the
requirements of HEC-18.
Alderman Creek 25 and 100 – Year Floodplain Study – Hillsborough County – development of a
stormwater hydrodynamic backwater model to calculate the historic pre-phosphate mining conditions and
post reclamations conditions for a 5,500 acre watershed.
IMC Fertilizer Mining Unit 13 – Hillsborough County – conducted a surface hydrologic analysis for a
2,200 acre expansion of the Four Corner phosphate mine. The study was prepared to compare the
existing stormwater peak discharges, pre-mining, to that of the proposed conditions, after reclamation,
and develop a reclamation plan that would maintain existing flows and volumes.
Disney 410-acre Wetland Enhancement – Evaluated the existing and proposed conditions and
developed requirements to hydraulically enhance a large wetland system north of Epcot Center Drive in
Disney World.
Whittenhorse Creek, North and South Wetland Creation Sites – Designed and permitted two 21-acre
wetland mitigation creation sites adjacent to Whittenhorse Creek in Disney World using a mass balance
approach to establish the hydraulic parameters.
Alderman Creek Restoration – Hillsborough County – developed a restoration plan to restore historic
water levels and volumes to the downstream wetlands associated with mining activities.
Steinhatchee Springs / Apalachicola River Wetland Restoration Plans – As part of an offsite
mitigation plan for forested wetland impacts associated with construction of an 800-mile natural gas
pipeline; developed a plan to rehydrate forested wetlands located along the Steinhatchee (452.8 acres)
and Apalachicola (934.2 acres) river floodplains. In the early 30s and 40s, the areas were logged. This
activity resulted in the construction of elevated dirt roads to access the timber. These roads isolated the
wetlands and prevented the natural flushing and hydration provided by the rise and fall of the rivers. A
plan was also developed to install culverts, bridges and low water crossings to re-establish the natural
historic hydrology.
Red River Wetland / Tara Wildlife Management Area Wetland Restoration Projects – As part of an
extensive survey of offsite mitigation opportunities for wetland impacts associated with construction of an
800-mile natural gas pipeline, two sites were selected and located in the Mississippi delta restoration.
The existing sites (Red River, 140 acres and Tara, 100 acres) were active farm land that historically
consisted of hardwood forested wetlands. A plan was developed to restore the historic hydrology to the
sites by removing levees and constructing water control structures to recreate hydroperiods. Developed
a plan and evaluated the daily hydraulic performance of the enhancement site, a water budget or mass
balance analysis was performed. The basin area contributing to runoff was calculated and a runoff curve
number assigned. Daily rainfall data for typical wet, average and dry years were obtained from nearby
monitoring stations. Runoff volumes were calculated based on total rainfall, watershed area, and runoff
curve numbers. The runoff volumes were reduced due to losses in soil storage, evapotranspiration,
horizontal permeability and losses due to drawdown. After hydroperiods were engineered, a biologist
established plant schedules based on water level fluctuations and probability curves.
