exclusions, re-evaluations, and continuous activity memoranda. Projects
involve site reconnaissance, database reviews, agency coordination,
public involvement, meetings with affected property owners, air and
noise analyses, socio-economic research, wildlife habitat assessments,
wetlands determinations/delineations, permitting, hazardous material
assessments (Phase 1), cultural resources coordination, and Section

Civil
Associates, Inc. provided professional services for the analysis of
various noise mitigation alternatives for IH 30 in the City of Dallas.
Using TNM ®, CAI developed baseline and future design noise
models,
modeled various abatement alternatives, calculated cost-benefits, and
researched and developed recommendations for city staff and council.
CAI participated in community meetings to present results and answer
questions.

Kelly
Parkway Corridor Study and Environmental Impact Statement –
San Antonio, Texas:
As
sub-consultant, Civil Associates, Inc. provided air and noise analyses
expertise for this new location parkway from US 90 to SH 16. CAI
identified noise receivers that could potentially benefit from noise
abatement measures; field-measured existing levels within the study
area and near existing railroads and airport; and determined future
design-year noise levels utilizing TNM ® for project
alternatives.
In areas where impacts occurred, CAI analyzed noise abatement measures
and modeled noise walls to determine the feasibility and reasonableness
of mitigation. Four noise walls near residential areas were found to
mitigate future noise effectively. Estimated time of completion and
design-year air quality models were also developed for all project
alternatives, including the no-build. Carbon monoxide (CO) emission
rates were calculated using MOBILE, and CO concentrations were
determined using CALINE. Documentation of noise and air quality results
were made in technical memoranda and in the DEIS.

FM
981 at Desert Creek – Collin County, Texas:
This
project in far northeast Collin County involved replacing the bridge
and approaches for this 2-lane roadway and required additional ROW.
Civil Associates, Inc. assisted the Texas Department of Transportation
in the preparation of the categorical exclusion environmental document.
Substantial issues that were faced when preparing the document
included: tree mitigation issues associated with the removal of
approximately one acre of riparian habitat and fenceline vegetation;
mature, and unusual vegetation impacts; and an archeological impact
evaluation. In addition, MAPOs (Meetings with Affected Property Owners)
were held with four surrounding property owners. |
