Documents


In the past 10 years, our NEPA experts have prepared over 150 environmental documents. We have done everything from large Environmental Impact Statements (EISs), to Environmental Assessments (EAs), Categorical Exclusions (CEs), State Environmental Studies (SESs), and other planning and feasibility documents. We are also experienced at ensuring those documents are Section 508 compliant. When you choose Horrocks, you can count on receiving the highest-quality, legally defensible documents on-time and in-scope.

Our clients save time and money because our environmental services are done in-house by a diverse team of resource specialists. We also offer exceptional in-house public outreach services to inform the public and get them excited for your project.




Permitting


Environmental laws and regulations are ever changing. Our environmental professionals understand current permitting legislation and guidance so you can move forward with confidence on your project. We regularly coordinate with federal, state, and local agencies to help our clients obtain:

  • Section 404 of the Clean Water Act Permits
  • State Stream Alteration Permits
  • Conditional Letter of Map Revision (CLOMR) Floodplain Development Permits
  • Letter of Map Revision (LOMR) Floodplain Development Permits

We also do mitigation development and planning. Many of our past projects have involved assisting clients with wetland mitigation site development, noise walls, and other mitigation measures. We look forward to helping you find the balance between the needs of the communities your project will serve and the resources that may be impacted.

ENVIRONMENTAL PROJECTS

NEW UTAH STATE CORRECTIONAL FACILITY ENVIRONMENTAL SITE ASSESSMENT


The State of Utah is relocating the State Correctional Facility to a location in Salt
Lake City west of the International Airport and north of I-80 in the NW Quadrant. The
site is currently undeveloped and requires new roadways and utilities to support
the new correctional facility development. In addition to performing the role of lead
civil design for the prison site development of approximately 150 acres (which
will accommodate up to 3,600 inmates), Horrocks is designing approximately five
miles of new paved roadway (to access the facility from I-80 and 5600 W through
the International Center), a new storm drainage collection system, culinary water
transmission lines, and a sanitary sewer system. Off-site roadway and utility
design is ongoing and anticipated to be complete in late 2018 with an estimated
construction cost for offsite civil between $70-$90 M. Horrocks is providing onsite
and offsite civil engineering services, including: Survey, roadway, utilities, grading
and environmental (Wetland and Waters of the US Delineations, Class I and Class III
Cultural Resource Inventories, and Coordination with US Army Corps of Engineers
and State Historic Preservation Office (SHPO).




I-80/SR-89 (STATE STREET) INTERCHANGE STUDY EIS


Horrocks conducted an Environmental Impact Statement (EIS) to evaluate
transportation and safety needs at the I-80 and State Street Interchange in
South Salt Lake City, Utah. Key elements of the EIS included purpose and need,
preliminary design and traffic analysis (regional modeling and microsimulation)
for over 20 alternatives, GIS data collection and analysis, environmental resource
analysis (economics, cultural resources, Section 4(f), noise, and air quality), and
coordination with agencies, stakeholders, businesses, and the public. The Selected
Alternative included widening the I-80 structure to accommodate an additional lane
on State Street and constructing a westbound frontage road between State Street
and Main Street to allow for multiple access points to South Salt Lake City.




OLMSTEAD HYDROELECTRIC POWER PLANT REPLACEMENT PROJECT ENVIRONMENTAL ASSESSMENT


Horrocks prepared an EA for the Central Utah Water Conservancy District(CUWCD) to analyze the environmental impacts of proposed replacements andmodifications to the Olmsted Hydroelectric Power Plant located in Orem, Utah.Possible updates included constructing a new power house, replacing thepenstocks, and installing a pipeline in the Olmsted rock tunnel. Keyelements included: Provo River resources, cultural resources, visual impacts,threatened & endangered species, wildlife, waters of the U.S., and coordinationwith USACOE, USFWS, and SHPO.




SNAKE RIVER AVENUE ENVIRONMENTAL ASSESSMENT


Located in Lewiston, Idaho, this project will make improvements to Snake River Avenue as traffic demand increases. A roundabout is being constructed for better
traffic flow and road widening is planned for the near future. The avenue runs
parallel to the Snake River and is flanked by businesses, a park, and railroad tracks.
Horrocks Engineers performed an Environmental Assessment to determine how best
to design the roundabout and lane widening to ensure minimal impact to existing
infrastructure, as well as water quality of the river for the sake of communities
alongside the river, as well as the variety of threatened and endangered species
(including Bull Trout and a variety of salmon species) living within it.
Given the roadways’ close proximity to Snake River, Horrocks obtained the
necessary environmental permitting including Section 404, NPDES, Storm Water
Construction, MS4, and Water Quality 401 Certification. To best ensure water quality
in the river, we designed detention ponds and determined their ideal locations.
This was determined in collaboration with the Army Corps of Engineers, and their
existing and future flood control mitigation in the area.
