Subject: Comment on Fahey Residence- BLD#20090396
JoAnne,
Here are my comments on the aforementioned site:
Page 1 of 1
The approach described in the submittal to handle the drainage from the proposed additional
impervious surface may be acceptable to the City. Additional information is requested
regarding an off-site drainage analysis.
It appears from the "Drainage Plan" submitted and from City topographic data that the
dispersal path will be in westerly direction. In addition, the "Drainage Plan" shows runoff from
the property to the south and the north entering the Fahey property. There is concern,
especially in large storm events, that the homes located on Sunset Ave N, directly behind the
Fahey's (at 606 & 608 Sunset Ave N) may be the recipients of unwanted stormwater. The City
recently got a call from a resident a 342 Sunset Ave N. (600 feet SW of the Fahey's property)
regarding water seeping into their basement from the southeast (the direction of 2nd Ave).
Please provide a qualitative off-site drainage analysis that discusses any erosion or drainage
impacts that may be caused or aggravated by the proposed project. Aggravated means
increasing the frequency of occurrences and or severity of an existing problem. Inquire with
the neighbors on Sunset Ave N. that are downstream of this project regarding any past
flooding or erosion problems on tinier properties.
The applicant my also want to consider connecting the site drainage to the City's storm line
that traverses the property to the south (601 2nd Ave). It appears that the line is approximate
30 feet from he Fahey's southwest property corner. An easement from the adjacent property
owner to the Fahey's would be required prior City approval of the connection,
Sincerely,
Jerry Shuster, P.E.
