Engineering Review Page 2 April 8, 2004 Fox Den Acres .City of Lino Lakes, Minnesota accordance with the local Flood Insurance Rate Map. A ponding and flowage easement in favor of the City of Lino Lakes, corresponding roughly to the Flood Zone limits, is also indicated on the Plan. A Letter of Map Amendment (LOMA) will ultimately be required to perform the improvements as proposed. 3. Ordinary and High Water Elevations for the remaining wetlands on the site have been provided. The wetland sizes and water elevations vary throughout the site. The wetland boundaries were performed by Earth Sciences in September 2003. 4. A Resource Inventory Survey has also been prepared for this site. The site is generally undulating with mixtures of wooded areas, pasture, and wetlands. Soils are generally fine sands and fine sandy loams with the exception of areas of muck in the vicinity of the lower flood plain areas. The soils indicated are from the Soil Survey by the USDA Soil Conservation service. However, actual soil borings, including groundwater elevations have not been provided. 5. MUSA Boundaries: A majority of the proposed subdivision is within the MUSA Boundaries. However, Parcel B along with Lots 23, 24, 25, and 27 in Block 4 on the easterly side of the subdivision are not within the MUSA service area. Thus, utility services can not be provided to these four lots at this time based on current MUSA Boundaries. The Developer will need to discuss with City Staff the implications of the MUSA restrictions. For example, the location of a temporary cul- de -sac and/or other utility placement may be necessary. Also, Parcel C along with portions of Lots 9, 10, 11, 12, 13, and 18 are outside the current MUSA service area. The MCES staff will need to be consulted to determine if there are service restrictions in these circumstances. Grading and Drainage 1. A General Stormwater Discharge Permit, Minnesota Pollution Control Agency (MPCA), will be required in accordance with the most current requirements of NPDES Phase II and State of Minnesota regulations. All NPDES regulations and requirements in accordance with the MPCA shall be adhered to, including submittal to the City of a Stormwater Pollution Prevention Plan (SWPPP). 2. Sedimentation and Erosion Control must be enforced at all times during the course of all grading and utility work. This includes the establishment of silt fence around all graded and disturbed areas, and the sweeping of streets on a regular basis, and as directed by the City. In the event the Contractor does not maintain erosion control as required, any costs incurred by the City as a result will be withheld from escrows or other monies due. It is strongly suggested that a note be added to all construction Plan sheets (including grading, streets, and utilities) reminding the Contractor to address erosion control requirements be added to all grading and erosion control sheets. The Grading Plan indicates that wetlands shall be replaced at a 2:1 ratio per requirements of the Wetland Conservation Act. At this time, it does not appear that any filling into the Flood Plain is proposed. The Plans also must be approved by the Rice Creek Watershed District (RCWD). A permit application has been submitted to RCWD (Permit No. 04 -039, dated March 12, 2004). RCWD has determined the application to be Incomplete, pending the receipt of several additional items. All requirements of the RCWD must be met.
