RE:
Storm Water Management Plan and Hydrologic Study
SEH No. P-ALBEV0305.00 14
You may recall a recent letter from the Wright County Soil and Water Conservation District (SWCD) that
identified a serious potential for future flooding problems in Albertville. The August 12, 2002, letter
explains that future flooding could result from further development and redevelopment projects within the
city without first having a better understanding of the downstream impacts and the capacity of the existing
drainage systems.
Another issue you have likely heard of is the National Pollutant Discharge Elimination System (NPDES)
Phase II storm water permit requirements for "small" urban areas (primarily cities) that are intended to
regulate storm water discharges from municipal separate storm sewer systems (MS4s).The regulations are
mandated by the USEPA and administered in Minnesota by the Minnesota Pollution Control Agency
(MPCA). The MPCA completed a Phase II permit for small MS4 cities and has published a list of cities
that are subject to the regulations. Albertville is not on the original list published by MPCA. However,
additional cities will be designated as Phase II cities in December 2002, and we anticipate that Albertville
will be included at that time. The original Phase II cities have until March 10, 2003, to complete a Storm
Water Pollution Prevention Program (SWPPP) and submit a Notice of Intent (NOI) for permit coverage.
Cities designated in December will have an additional 18 months to comply with these requirements.
A related, but not required, element of the Phase II SWPPP efforts is to collect and summarize the
available water resources and storm water management data (land use, surface waters and hydrology, soils
and geology, etc.) for the City. This effort is similar to background sections of a City's storm water
management plan (SWMP). We recommend that these background sections, hydrologic study and Phase II
SWPPP be combined into a single document to serve as the City's comprehensive SWMP.
For your consideration, we have prepared the following fee estimates to complete these tasks for the City:
Hydrologic Study (north portion of city) $11,500
Prepare Background for SWMP $ 3,000
Phase II SWPPP and NOI (includes $3.000 software package) $21.500
Total $36,000
