NS Services has prepared numerous NEPA Documents to include Categorical Exclusions, Environmental Impact Statements, Environmental Assessments, Waters Reports, and Wetland Delineation & Mitigation Plans for Transportation Projects. Following is a brief list of projects:

Wetland Mitigation Design and Permitting

Impacts to water resources occurred as a result of proposed SR 42 roadway improvements. Seven wetlands (total of 0.97 acres) were impacted by the proposed roadway project.

Mitigation for this project was designed at the site referred to as the Smidley Property. Three potential areas for wetland creation/enhancement were initially investigated at the Smidley Property during mitigation site suitability efforts. Through a process of agency coordination, preliminary mitigation potential analysis, and minimization measures at the impact sites, preferred location for wetland creation/enhancement was determined.

The proposed mitigation design included a combination of native plantings and minimal site grading and hydrology manipulation to provide a combination of forested, shrub-scrub, and emergent wetlands; as well as approximately 870 linear feet of stream bank riparian buffer creation. Mitigation & Monitoring Plan, Construction Drawings and a cost estimate were prepared. Permit requirements as dictated by the IDEM and US Army Corps of Engineers 404/401 were obtained.
