RE : proposed walgreens project — City of Oak park Heights
Dear Ken:
FAXED AND MAILED
FAX # 439-7188
Our office has received and reviewed the construction plans and specifications dated April 20, 2001 and revised
September 5, 2001, for the proposed W algreens project site, located at the existing Bradshaw Funeral Lorne in
Section 34, Town 30 Forth, Range 20 west, City of Oak Park Heights. Since the site plans are essentially the
same since nay May 14, 2001 letter I will only comment. on what has changed.
Qtnrm wn fpr
Storm water is still planned to�routed through a storm sewer except now all run off will pass through an in -line
structural storm water treatment system. The proposed model to be used is the "Stormceptor v2B 1." This
structure will address water quality issues, however, it should be specified if the owner or city is responsible for
maintenance. The only other issue regarding storm water is rate control. Under the post development scenario,
the rate of runoff will increase. See the May 14, 2001 comment for details. The methods that could be used to
address rate control on this site appear to be in conflict with the parking and landscaping requirements of the
city. Also, this site is already constrained due to its size. Therefore, I believe the City should evaluate this and
other sites that have no storm water treatment and develop a comprehensive plan to address runoff from
redevelopment of existing commercial properties.
Grading and Erosion Control
I have no other comments except upon careful review of the notes on page C3.1, it appears that note # 5 & 6 are
in conflict. I would assume that note # 5 would tape precedence over note # d. In either case, at a minimum, all
perimeter controls (silt fence) should be installed prior to grading. Additional silt fence, as needed, may be
installed during construction to address specific run off problems.
