Re: Department Review of the Woodbury Addition Re-Plat and Planned Unit 
Development  
After reviewing the preliminary re-plat and planned unit development (PUD) for the Woodbury 
addition, the engineering department has a few of recommendations for consideration at this 
stage of the re-platting process. We don’t anticipate that the traffic on Mountain View Road will 
increase significantly from the original plat to the re-plat. Based on the TIS submitted with the 
original plat, the additional lots won’t have a significant impact on the LOS at F Street and Mt. 
View. The improvements on Mt. View to mitigate the impact of the Woodbury Subdivision have 
already been installed. As with the original plat, more analysis/mitigation may be required when 
the connection to Orchard Ave. is completed. The increase in the number of lots and density 
from the original plat will have an impact on some of the utility systems . As a result, please 
consider the following: 
1. The addition lots will have a negligible impact on domestic water demand in the area, 
however the addition of NB zoned lots with potential commercial uses may increase the 
fire flow demand in the subdivision. The water modeling report for the original plat was 
done prior to upgrades to the Ponderosa pump station and it recommended connecting 
to the main pressure zone in Slonaker as the Ponderosa station was insufficient to serve 
the development.  After that water model analysis was completed, the City constructed a 
new pump station serving the Orchard Ave. pressure zone and the Woodbury Addition 
was included in the potential service area of that pump station design. The developer 
has also constructed a connection to that pressure zone and installed a PRV near the 
connection to the main pressure zone in Slonaker, expanding the Orchard Pressure 
Zone as intended in the new pump station design. Flow tests of the system near the new 
commercial lots indicate an available fire flow of 3800 gpm.  Fire Flow at that capacity 
should be sufficient to serve the majority of uses in the NB Zone.  Any supply 
deficiencies for other uses can be mitigated by installing fire suppression systems in the

building and/or constructing a building with a more fire-resistant building construction 
type. 
 
2. Because of the increased density and subsequent increase in overall impervious area of 
the development, the Woodbury stormwater report will need to be revised and any 
necessary modifications to the existing detention pond will need to be completed with 
the next phase of the development. 
 
3. The sanitary system as designed should be suffic ient to serve the additional lots 
however the additional demand will exacerbate the issue downstream of Slonaker and 
the planned Lanny connection should be required with the next phase of the 
development. 
 
4. The proposed re-plat shows the Woodbury Drive RO W width decreasing from Sixty feet 
(60’) to Fifty-Four feet (54’) north of Cottage Lane. The proposed re-plat indicates that 
Woodbury will continue to be a public street.  The Woodbury ROW shall stay 60’ wide if 
it is going to be a public street.   
This concludes our comments for this preliminary application. Please let me know if you have 
any questions or comments.

Bob Buvel
