Hi Marla,
The Stormwater Section has reviewed the “Burlington International Airport – Rehabilitate TWY A and Construct New
Paved TWY Shoulders” site plan prepared by McFarland Johnson, dated 2/18/22. We would like to offer the following
comments:
1. The HydroCAD model appears to use 13.730 in/hr for an infiltration rate for the proposed infiltration system. It
appears from the Geotechnical Investigation report that the average of the two nearest infiltration rates (SW-9
& SW-10) to the proposed infiltration system is 15.7 inches per hour. Applying a factor of safety of 2, would yield
an infiltration rate of 7.85 in/hr. Please confirm how the 13.73 in/hr was arrived at.
2. Consider adding an isolator row to the proposed infiltration system, with manholes on either end for
maintenance purposes.
3. The DRB should include a condition requiring the applicant to regularly maintain all stormwater treatment and
conveyance infrastructure.
Thank you for the opportunity to comment,
Dave

Hey Dave, just a reminder on this. I’d like to prepare this as a draft decision if there are no issues with
stormwater. Thanks.

Hi Dave,
This application will be reviewed by the Board at the April 19 DRB hearing. I believe your department is the only one
other than P&Z needs eyes on this, but if you notice anything else please let me know. Please provide comments by
next Friday 4/8.
Just a reminder, comments you provide are inserted directly into the staff report for the project, so please frame your
response for public consumption.
