3.16.1.1.2 If the area of wetlands impacted is over the regulatory
maximum, wetland mitigation will be accomplished according to the
standards of the local or state water resources agency. The site size
may not have sufficient area to accommodate wetland mitigation. Off-
site mitigation or purchase of wetland mitigation credits from
established wetland mitigation banks may be required, but should be
avoided if possible due to associated costs and complications of off-
site work.
3.16.1.2 Noise and Air.
3.16.1.2.1 Any noise and air impacts identified from the
Environmental Assessment which require mitigation or permitting will
be incorporated into the design. Typical emissions from a site might
include boilers and other equipment that emit heat, fumes or particles.
3.16.1.2.2 Typically, site locations are in areas which permit
commercial or industrial type uses with corresponding noise and air
quality standards. The general layout of the site should consider
locating areas of concentrated vehicle operations and associated noise
away from neighboring properties for which noise may be an issue.
3.16.1.3 Traffic Safety
3.16.1.3.1 As outlined in Section 3.2, coordination with local
roadway agencies and implementation of DOT recommended
roadway geometrics will accommodate a majority of the site traffic
safety needs. The roadway agency may dictate control devices such
as stop signs other roadway design features at access points.
3.16.1.3.2 If the size of the site and its interior site traffic circulation is
substantial, consider designing traffic control signs such as stop signs,
pedestrian crossing warning signs, pavement markings, directional
signs, information signs, and speed limits to provide safe traffic control
and eliminate confusing traffic patterns on the site.
3.16.1.4 Groundwater
however, some sites may have shallow groundwater tables which may
affect the methodology of construction, and require measures such as
temporary dewatering to install items such as deep utilities and
foundations. The contractor will be required to obtain the necessary
state and local permits for dewatering operations and to control its
