TRA provides peer review of environmental documents and technical reports prepared by others. These reviews are typically conducted for a client to assess adequacy of a lead agency CEQA/NEPA document in addressing environmental issues of concern in relation to CEQA/NEPA requirements. TRA also provides planning assistance to local agencies such as providing guidance on implementation of local habitat conservation plans affecting development permit applications, determining the appropriate level of CEQA analysis, and development of project descriptions and assessments needed for project grant applications. TRA has provided instructional seminars for public agencies submitting grant applications to California State Parks (aka California Department of Parks and Recreation) for funds pertaining to management of off-highway motor vehicle recreation. TRA has also provided expert testimony on technical issues such as wastewater sludge disposal, utility lines in habitat conservation areas, and the effect of plastic pipe usage on potable water supply.
