| <br />COX/ McLAIN <br />*:TMK' Enviror n', - 1fing <br />Task 2 — Environmental Constraints Analysis <br />Subtask 2.1 Draft Environmental Constraints Analysis <br />CoxMcLan Environmental Consulting will perform desktop research to obtain readUy-ovoilab|e, digital <br />environmental constraints information from appropriate local, state, and federal agencies. Ahigh- level <br />engineering design domohp4|on of Option 1 and Option 2 under the proposed action will be developed to <br />aeaiod with the environmental constraints analysis. Add|t|onaHy, the following environmental topics will be <br />the focus of the environmental constraints analysis: <br />Cultural resources records review to determine the extent of previous studies and identify known <br />historical or archeological sites in the proposed action area, with the action area understood as the <br />preferred alternative with m construction footprint of 50 aonyo or fewer. The work would include o <br />search of archeological records maintained by the Texas Archeological Research Laboratory <br />(TARL) and o review of the Texas Archeological Sites Aduo maintained by the Texas Historical <br />Commission (THC)for cemeteries and recorded h|mtohuo| markers, properties, or districts listed in <br />the NmU000| Register of Historic P|n000 (NRHP). As a political subdivision of Texas, CoBPW must <br />notify the THC prior to commencing any project onpublic land that will involve 5ormore acres nf <br />ground disturbance; 6.000 or more cubic yards of earth moving; will occur in o historic district; or <br />will affect o recorded archeological site. This scope includes records research to inform the <br />development of an Antiquities Permit for intensive archeological survey as well as the required <br />reporting and nanondnouredion. <br />Upon conclusion ofthe desktop research, we will perform abrief one U>day field survey of the proposed <br />action area to verify information obtained through desktop research and to document any additional <br />environmental constraints. Proposed action area photographs will also be taken to highlight the <br />environmental constraints. The results of the desktop research and brief field survey will be summarized in <br />odraft environmental constraints letter report for Cn5yWand HUD review. The report will consist of aehnrt <br />proposed action dennripbon, mmeihndnlogy, text summary of environmental conntra|nhe, table summarizing <br />the identified environmental constraints and potential regulatory requirements orpermitting insues, maps <br />displaying environmental constraints information, and proposed action area photographs. <br />Subtask 2.2 Final Environmental Constraints Analysis <br />One set ofnon-contradictory comments on the draft environmental constraints analysis in expected from <br />{oSMand HUD. Upon receipt of comments, [oxIMcLainEnvironmental Consulting will revise the draft <br />environmental constraints analysis for the design engineers to use in the further refinement of Option I and <br />Option 2 of the proposed action. <br />Meeting� <br />" Conference call with CVSM and HUD to review the draft environmental constraints <br />Deliverables <br />w One (1) draft environmental constraints analysis (electronic version only). <br />• One (1) final environmental constraints analysis (electronic version only). <br />0 One set of comments onthe draft environmental uonatraintsemalysis. <br />
