Railroad Topographic Surveys  

Crouch Engineering uses the latest tools for the collection of GPS based data needed for various digital terrain models, maps, charts and plans.  The railroad topographic survey is the basis for all designs, and should be conducted by experts in railway surveying.  That’s why Crouch Engineering uses its own experienced staff of eRailsafe certified, annual RWP trained surveying staff to perform all our railroad surveys.


Crouch Engineering uses GPS receivers, GPS survey equipment, aerial surveys, LIDAR surveys, and other tools for the collection of GPS based data needed for the preparation of maps for planning and engineering purposes including location maps for plans, the preparation of track charts, geographical and graphical presentations of data, conceptual plans, etc.  


Crouch Engineering utilizes ground surveys and aerial surveys to produce many of its maps, and has access to USGS maps and other existing digital format maps and ArcView Compatible databases.  

Phase 1 Environmental Assessments

Crouch Engineering performs Phase 1 environmental assessments for due diligence related to mergers and acquisitions.

Environmental Permitting and Design

Crouch Engineering performs environmental permitting and design for all types of railroad, highway, transportation, and site design projects 

Environmental Permitting - Crouch Engineering performs environmental assessments for major projects, phase 1 environmental site assessments, and environmental permitting and design for all types of railroad, highway, transportation, and site design projects. By performing environmental permitting in house, Crouch Engineering reduces the design timeframe for most projects, improving the project schedule, and reducing costs.


Crouch routinely performs NEPA reviews for linear transportation projects, and works with its clients, and Federal and State agencies to prepare efficient plans, reduce impacts to wetlands and streams, mitigate impacts, and reduce permitting time for its design projects. Crouch Engineering has been very successful and has a stellar reputation in the railroad industry based on our history over the last two decades in streamlining permitting times, and getting approvals in a very reasonable timeframe for its construction projects.


Crouch Engineering is on the approved list of providers for Environmental Assessments of the Federal Surface Transportation Board.


Our projects typically require submitting Notices of Intent for Grading, and agency review.  Crouch Engineering designs workable, efficient designs for erosion and sediment control devices, and pollution control plans for all of its grading related construction projects.  Crouch routinely develops Storm Water Pollution Control Plans, conforming to state and local requirements, for contractors to use during the construction phase of its grading projects. Our plans are developed with the intent and purpose of not allowing any sediment to leave the construction site.


Crouch Engineering conducts historical, archaeological, endangered species, wetlands and other environmental reviews and studies for major track and bridge projects. We work directly with federal, state and local agencies to address all required areas of environmental concern. 


Crouch Engineering Prepares Stormwater Pollution Prevention Plans (SWPPPs), Spill Prevention, Control and Countermeasures (SPCCs) and storm water treatment permits for its railroad clients’ repair and maintenance facilities, and SWPPPs for construction projects. EPA requirements are fulfilled in the SWPPP and SPCC plan production process. Crouch Engineering develops training plans and other documents required by the EPA. 


In performing the design of new projects, Crouch Engineering always looks for creative solutions and creative designs to reduce, eliminate, or mitigate impacts to streams and wetlands. We take pride in having accomplished this goal in many ways, on many projects.

Utility Research & Design

On virtually all of our capital design projects, Crouch Engineering is responsible for coordinating the utility research, establishing the location of above ground and underground utilities and having them located and marked prior to conducting topographic surveys. Crouch Engineering works with local utility companies, government utility boards and commissions, and other utility owners to identify potential crossings, and determine the need for adjusting or protecting each utility. If there are existing utilities crossing railroads,   Crouch Engineering helps determine whether the crossing is covered by an existing agreement. 


Crouch Engineering provides utility research, and coordinates field marking prior to survey and designs for all types of projects.


Crouch has assisted companies such as RailAmerica in setting up permit application forms and regulations, review and approval processes, and construction oversight for pipeline and other overhead and underground railroad utility crossings.  We routinely review utility crossing permit applications for many railroads across the USA.


For major construction projects, Crouch Engineering typically assigns one project manager the responsibility of utility coordination. Our project manager works with the railroad company or land owner to determine whether there are any existing utility agreements. The project manager also performs research to determine whether there are any existing utility easements, and what utilities are on site. In addition to calling the proper one-call number, the Project Manager contacts all local utilities and reviews utility maps, and where possible, downloads GIS utility system drawings so that all potential utilities can be identified.


Once utilities have been identified, Crouch Engineering works with the client and railroad to ensure that existing utilities are properly protected, and if necessary, utility adjustments, relocations, or casings are designed for utilities that impact the project.


During the construction phase of our projects, Crouch Engineering’s Project Managers coordinate the relocation or protection of above ground and underground utilities so that the project schedule is maintained, or improved. Crouch maintains a detailed database for each project, including utility owners, utility company contacts, lists of agreements, locations, data on the type of utility, the commodity being carried, whether underground carrier pipes are cased or not, and the proposed method for adjusting or protecting each utility crossing.
