A-1 A P P E N D I X A Survey Questionnaire GENERAL INFORMATION Dear State Department of Transportation Hydraulic Engineers, TheTransportationResearchBoard (TRB) ispreparingasynthesisonHighway Hydraulic Engineering State of Practice. This is being developed under the National Cooperative HighwayResearchProgram(NCHRP),withthesponsorshipoftheAmericanAssociationof State Highway and Transportation Officials (AASHTO), in cooperation with the Federal Highway Administration (FHWA). The purpose of this survey questionnaire is to learn what significant changes state DOTs have made to their hydraulic engineering policies and practices over the past decade and to identifynewsuccessfulpractices.Thereportsummarizingthesefindingswilldocumentthe state of practice. This surveypertains mainly tohydraulics topics and is being sent tothe statehydraulic engineers. If you are not the appropriate person at the agency to complete this questionnaire, please forward it to the correct person (see 'Instructions' - next page). Pleasecompleteandsubmitthissurveywithin3weeksofreceipt,February20.Weestimate it should take no more than 20 minutes to at least 30 minutes to complete. It is designed so you can exit and return to the survey in order to allocate your time over several days. Ifyou haveanyquestionsorproblemsrelatedtothisquestionnaire,pleasecontactourprincipal investigator, Ms. Melanie Kueber Watkins at (906) 231-3700 or mkueber@mtu.edu Thank you very much for your time, expertise, and support of the project!

Survey navigation is conducted by selecting the “Prev” (previous) or “Next” button at the bottom of each page. The questionnaire reflects the proposed questions to be included in the survey instrument. Thequestionsareorganized intosectionstohelpfacilitate thedatacollectionprocessfor the participants. Skip logic will be used to speed up the survey response time. This means that follow-up questions will only appear if an individual responds to the original question in a particular way. Circles indicate singular response, while boxes indicate multiple selections may be made.

Survey Questionnaire A-3 DEFINITIONS Alternative Delivery: Construction Management-At-Risk (CMAR): A design professional is selected and contracted for design, then a construction manager is selected for a second contract when the project is approximately 30-60% complete for a collaborative working relationship. The constructioncontractwiththeconstructionmanagerisrequiredtocompletetheprojectata guaranteed maximum price. Design-Build (DB):Thedesign andconstructionoftheprojectarecompletedbyaprivate entity that has a contract with the project owner Public Private Partnership (PPP): A public and private-sector contractual agreement (‘partnership’) is formed whereby a public facility is renovated, constructed, operated, maintained, and/or managed by a private partner. Usually the public entity retains ownership but possibly the private partner has invested capital. Construction Management General Contractor (CMGC): The owner engages with a construction manager during the design process to provide constructability input. When the project is approximately 60-90% complete the owner and the contractor negotiate a guaranteed maximum price. This is also referred to as CMAR. Low Impact Development (LID): Natural stormwater management processes usually decentralized from municipal systems that include measures to improve water quality at the source.Examplesarebioretention(raingardens),permeablepavements,andgreenroofs. Programmatic Agreement (PA): A document that spells out the terms of a formal, legally binding agreement between a state Department of Transportation (DOT) and other state and/orfederalagencies.Therearetwobasictypes:1)Project-specificPA-describesactions of parties to meet their environmental compliances for a specific transportation project, and 2) Procedural PA -an established process through which the parties will complywith for an agency program, category of projects, or particular resource.
