This master plan study addressed inventorying system components and conditions, performing hydraulic modeling of the system, analyzing system adequacy to meet current and future needs, identifying needed future improvements, providing cost estimates, and identifying funding opportunities to implement the improvements...

Guernsey visited and evaluated 33 sites. An Independent Engineers Report (IER) was developed by Guernsey. An Environmental and Regulatory Summary based on existing permits and approvals, the limitations and requirements they place on operations and a general assessment of each...

Guernsey identified all the significant historic undeveloped reservoir sites in Oklahoma (125 sites), reviewed existing information, performed a “Fatal Flaws” analysis to efficiently eliminate unsuitable candidates, and categorized the desirability of the remaining options. A total of 125 reservoir sites...

The assessment determined each facility’s renovation needs, developed an estimated construction cost for the recommended items in each facility, and prioritized the recommended renovations based on the funds available. Facilities assessed included log cabins and dining facilities. These structures are...

Services were assigned on a project-by-project basis by the Owner. A specific task was developed for each work order assignment. Services included: Conduct investigations, surveys, studies, reports, cost estimates, drawings, testing or other consulting services necessary for the Owner to...

Guernsey provided professional environmental consultant services under two Architectural & Engineering IDIQ contracts. The work was assigned on a project-by-project basis. There were approximately 37 environmental task orders performed under these contracts. Services included: Environmental Site Assessments and Impact Statements...

Guernsey performed general environmental engineering services to the Oklahoma Department of Transportation. ODOT issued Task Orders on a per-project needed basis. These services included the following: corridor-wide initial site assessments (Corridor ISA’s); parcel-specific initial site assessment (Parcel ISA’s); subsurface site...

Guernsey performed a study that considered three route alignments and conceptual design for alternative interconnected system routes for the Oklahoma Water Resources Board. The goal was to present viable options for potential water transfer from Lake Texoma, Eufaula Lake/Arkansas River...

Oklahoma County prepared and submitted a procedure to assure compliance with the existing Storm Water Management Program (SWMP) to the Oklahoma Department of Environmental Quality (ODEQ) for approval. Guernsey assisted the County Planner in the developing the procedure by employing...

Most of these clearances are addressed as categorical exclusions (CATEXs) and involve requirements for technical and field activities including biological reviews, wetlands investigations, cultural resources reconnaissance studies, and agency/tribal interface. On non-federally funded environmental clearances, Guernsey works directly with the...

The overall goal was to perform a feasibility study to determine if there is an opportunity for the development of a regional brackish water supply and desalination facility for an enhanced future water supply for COWRA. The study area included...

Guernsey performed initial groundwater investigations and quarterly sampling for the Oklahoma County Jail. This investigation and sampling were required because sewer lines under the County Jail were corroded, which allowed sewage, including kitchen waste, to seep into the groundwater regime...

Most of these clearances are addressed as categorical exclusions (CATEX) and involve requirements for technical and field activities including initial site assessments (ISAs), biological reviews, wetlands investigations, cultural resources reconnaissance studies, and the potential for noise studies. On federally funded...

After the performance of preliminary characterization studies for the region’s counties, communities, and rural water districts (population, water supply and infrastructure, water quality), it was determined a detailed feasibility study was required to address regionalization of water supply, treatment, and...

The Guernsey Team (included EDAW [now AECOM] and Alaback & Associates) prepared the Phase II Master Plan and Preliminary Reconnaissance for the Arkansas River Corridor through the Tulsa, OK metropolitan area. The Plan was developed in conjunction with the Vision...

Guernsey has decades of experience in preparing these studies in accordance with RUS Bulletin 1724D-101A guidelines, ensuring sound engineering and economic analysis. Our long-range plans are client-specific and consider system operating voltage, substation requirements, transmission requirements, primary feeder requirements and...

Guernsey completed a two-part rapid response systems integration and utility master planning task at the MCASI. Task 1 included: Station-wide system integration study to address current use and future implementation of ESS, UMCS, FAS, MNS, and SCADA systems. Survey of...

Enid has become, and will continue to develop into, a major regional retail hub for northwestern Oklahoma. Guernsey is assisting the city with preparation of a comprehensive plan that includes: Overall project management: project communication, and cost, schedule and quality...

One special consideration of this project was that the Public Utility Commission of Texas (PUCT) must approve all new transmission lines one mile or longer prior to construction. A CCN application was submitted for approval, which included responses to questions...

We initially installed a series of groundwater monitoring wells, or MWs, at the site to obtain soil and groundwater samples for lab analysis. During the investigation, we encountered roughly three feet of free-phase hydrocarbons in the groundwater; in the end...
