MEMORANDUM 
 
TO:  Deb Wallace, City Manager  
   
FROM:  Ben Burchfield, Public Works Director 
 
DATE:  August 3, 2023 
 
SUBJECT: Clark St Drainage Issues 
 
This memo is in response to a Co uncil Member request to provide an action plan for addressing 
resident flooding issues at Leveck and Clark St. Th ere has been extended discussion about what 
can be done to mitigate the is sues between the City and these property owners in the past. To 
summarize assessment on remedying the situation the department has done to date: 
 
1. The issue stems from a stormwater pipe size bottleneck. There is a 48” pipe coming into 
the North portion of the Ferguson property. This drainage tile starts at Cleveland Ave and 
follows the West side of Leveck St. It opens up at the Ferguson property to a grass swale, 
then it bottlenecks to a 24” pipe under the Leverett driveway. The City did not install this 
tile. It then opens  back up to a swal e for approximately 50 LF, then enters  a 30” pipe 
located in Leverett’s yard, where it travels approximately 200 LF before discharging in to 
an open he avily vegetated area, before it then enters a stone box culvert and travels 
under Tell St and Norfolk Southern ROW.   
 
2. Upsizing the driv eway pipe only (to mitigate stormwater backing up onto the Ferguson 
property) will move  the bottleneck downstream  50 ft that will then flood the Leverett 
driveway, yard, and potentially their home. This is simply  trading one problem for 
another. This issue necessitates having to address pipe across both properties to 
eliminate the issue. 
 
3. This means the  200 LF of undersized poor condition 30” corrugated metal pipe with 
virtually no cover (<6”, as little as none) that carries the water across the Leverett 
property and terminates around 100 foot above the N orfolk Southern box culvert would 
also need to be replaced . This pipe has already failed in several spots. It is a legitimate 
problem. Removal is the simplest , cheapest solution, but the Leverett’s will not want an 
open swale carrying all this water across the  length of their property. That leaves having
