RE: Review of storm water management practices: Outlets at Albertville -Phase III
SEH No. A-ALBEV0308.00
Storm Water (Lot Coverage Credits)
A review of the site plans submitted .to the City of Albertville by JMJ Properties, Inc., dated August 12,
2002, for the Outlets at Albertville, Phase II, determined that the impervious lot coverage for the site is
approximately .71.4%. This exceeds the 50% effective lot coverage threshold allowed under the City's
Shoreland Ordinance. Based on our review of the 16.46-acre .site, low impact .development (LID)
practices and/or other storm water BMPs that account for a total of 4450 cu. feet of runoff (fora 0.5-inch
rainfall event) are needed to reduce the effective lot coverage to 50%. This assume the actual lot
coverage stays at 71.4%.
Both infiltration and non-infiltration methods could be applicable to. the site. The Wright County Soil
Survey Manual defines the subsurface soils as being of the Haden, Dundas, and Nessel soil series. These
underlying soils are associated with permeability rates ranging from 0.2-0.63 inches per hour.
LID practices applicable to this site include depressed parking islands in the southern portion of the south
parking area. Other options include grated-infiltration trenches, rain gardens and/or a grass Swale along
the southern portion of the property. For example, a rain garden located at the southwestern edge of-the
site, with a surface area of 2000 sq. feet and a depth of one foot; would treat approximately 2000 cu. feet
of runoff from the southwest pazlirig lot. Drainage from. the lot could be conveyed to the rain garden
through acurb-cut section at the south end of the lot. Runoff from lazger events would be directed back
into the storm sewer system or into a grass swale. Either option would ultimately discharge into the
detention pond located on the east side of the site.
The following is, a summary of approximate runoff credits for various storm water options at the site:
Credit Needed =4450 cu.ft.
Rain gazden south of Southwest parking lot (curb cut from lot) 2000 cu.ft.
Approx. 3200 sq.ft. x 1.5 ft deep -~
Rain garden northwest comer of Bldg. D 750 cu.ft.
(Approx. 1200 sq.ft. x 1.5 feet deep)
Grass Swale along south/southwest property boundary 1250 cu.ft.
(Approx. 250 feet x 1 foot deep -curb cuts from pazking lot}
Infiltration trench(es) between parking islands throughout site 100 cu.ft. each
located to capture sheet flow (Approx. 50 sq.ft. x 1.5 ft deep each)
Depressed parking lot islands - bio-retention areas 60 cu.ft. each
(Approx. 100 sq. ft x 1.5 ft. deep each)

Wetlands
The use of rain gardens as credit for wetland mitigation is possible. However, the rain garden design
would have to meet wetland criteria and not receive direct storm water discharge without pretreatment.
EssentiaIly, they would need to create atwo-cell storm water treatment system with the second cell being
the rain garden. The pretreatment would have to be designed and constructed to meet 50 % phosphorus
removal as required by WCA. Additionally, the rain gazden would need to be designed far a maximum
24-inch rise in water Level for the 10-year~critical storm event and the design standards for a replacement
wetlands must be followed. The goal would have to be a palustrine emergent wetland. In reality, it does
not appear that the developer would be able to meet these requirements within the confines of the site,
especially considering the current site layout.
The avoidance of wetland impacts should also be evaluated furt_ her. If the site design involved moving or
rearranging a building layout in order to avoid wetland impacts the developer may not have to provide the
additional compensation (i.e., approximately 0.3 acres) since there would be zero or reduced impacts to
one or more of the wetlands. Additionally, credit could be granted for the vegetative restoration . of .the
wetlands avoided if additional credit is needed. Is alt of the parking shown on the site plan necessary to
meet City requirements? Can they reduce the number of parking spaces? Another possibility is for the site
design to have the replacement wetland in the south portion of the site, move the longer building to the
east and avoid wetland impacts. There must be enough watershed to support the avoided wetland as it
currently exists. Also why couldn't the buildings be two story to avoid wetland impacts?
