The USDA FL-ENG-21B form is a critical document used for the assessment of time of concentration or travel time within specified projects. This guide will provide users with clear, step-by-step instructions on how to accurately complete the form online.

Follow the steps to fill out the USDA FL-ENG-21B form effectively.

1. Click the ‘Get Form’ button to access the USDA FL-ENG-21B form and open it for editing.
2. Begin by entering the project name in the designated field, ensuring it accurately reflects the nature of the work being assessed.
3. Fill in the 'Designed By' section with the name of the individual or organization responsible for the design.
4. Enter the date on which the form is completed in the 'Date' field.
5. Provide the specific location related to the project in the 'Location' field; this may include geographical details or site references.
6. In the 'Checked By' section, input the checker’s name to confirm validation of the details provided in the form.
7. Enter the 'Checked By' date to record when the review took place.
8. Circle 'Tc' or 'Tt' based on the focus of your analysis to indicate whether you are calculating time of concentration or travel time.
9. Complete the 'Sheet Flow' section by providing the required segment ID, surface description, Manning’s roughness coefficient, flow length, two-year 24-hour rainfall, land slope, and compute Tt accordingly.
10. For the 'Shallow Concentrated Flow' section, repeat similar steps for segment ID, surface description, flow length, watercourse slope, and compute Tt based on the formula provided.
11. In the 'Channel Flow' section, fill out the cross-sectional flow area, wetted perimeter, hydraulic radius, channel slope, and Manning’s roughness coefficient; compute velocity and Tt as indicated.
12. Lastly, tally the watershed or subarea T_c or T_t by adding the calculated Tt from previous steps, ensuring the total reflects accurate data.
13. Once all information is entered, save your changes, download, print, or share the completed form as necessary.
