NCHRP 55-18 Design, Construction, and Monitoring Practices for Aquatic Organism Passage

Instructions and General Questions

Page description:

Dear State DOT Hydraulic Engineer,

The TRB is preparing a synthesis under NCHRP Project 20-05 Topic 55-18 on Design, Construction, and Monitoring Practices for Aquatic Organism Passage (AOP). This is being done for the NCHRP, under the sponsorship of the AASHTO, in cooperation with the FHWA.

The purpose of this questionnaire is to identify, document, and summarize practices used by DOTs to design, construct, and monitor structures that ensure aquatic organism passage. The results of this questionnaire will be incorporated into a synthesis of highway agency practices, with the intent of helping DOTs evaluate and improve their current AOP practices.

Typically, staff within the environmental, hydraulic, and/or construction divisions would be appropriate to fill out this survey since it asks detailed questions about AOP structure programming, design, construction, and monitoring practices. We realize AOP practices may be shared across various offices in your DOT, so you may consider seeking additional guidance from colleagues in completing this questionnaire. If you are not the appropriate person to complete this survey, please forward it to the correct person at your DOT.

Your expertise and experience are critical to the success of this synthesis of highway practice. We thank you in advance for your time and thoughtful consideration. Note that DOT survey responses will be shown in the published synthesis report. However, the identity of survey respondents will remain anonymous.

Please complete and submit this survey by February 23, 2024. We estimate that it should take no more than 30 minutes to complete. It is designed so you can exit and return to the survey if you need to allocate your time over several sessions. If you have any questions or problems related to this questionnaire, please contact Justin Lennon.

QUESTIONNAIRE TIPS

If you are unable to complete the questionnaire in one sitting, you can return to the questionnaire at any time by reentering through the provided survey link as long as you access the questionnaire from the same computer and browser. Reentering the survey will return you to the last completed question.
Survey navigation is conducted by selecting the “Back” (previous) or “Next” button at the bottom of each page.
Until you submit the survey, you may revise your answers at any time.
There is no time limit once you begin the survey.
The back button on the browser should not be used.
All fields that have an asterisk are required.

For reference, a PDF of the questionnaire is attached to the original email. If you did not receive the PDF questionnaire, one can be requested by contacting Justin Lennon.

Thank you for sharing your time and expertise with the DOT community.

GUIDANCE

This questionnaire seeks to synthesize DOT practices and activities in designing, constructing, and monitoring structures that deliver aquatic organism passage. If your DOT has not designed, constructed, nor owned structures for AOP, you will only need to answer up to Question 3 of this questionnaire. For the purpose of this questionnaire, please consider the following definitions:

DEFINITIONS

AOP: Aquatic Organism Passage
AOP Structure: Permanent structures that are designed to provide for passage of aquatic organisms (e.g., culverts, bridges, three-sided structures (open top or open bottom), or nature-like fishways).
Bridge: A structure of any size that consists of a deck supported by abutments and/or piers with the road surface integrated into the structure.
Culvert: A buried structure that conveys a waterway under a road. Culverts may be boxes, pipes, open bottom culverts, etc. where fill is present between the structure and the roadway. The definition of culvert for the purposes of this study is not limited to the FHWA/NBIS 20-foot span limit.
Anadromous Fish: Fish species that enter fresh water from the sea to spawn and returns to the sea for most of its adult life.
Catadromous Fish: Fish species that spend most of their adult lives in freshwater but must return to the sea to spawn.
Salmonid: Migratory cold water fish species that spawn in shallow waters and spend most of their adult lives in larger waterbodies.
