Eagle Brook Church Review Page 3 January 7, 2004 City of Lino Lakes, Minnesota areas adjacent to Peltier Lake are proposed to be left naturally as is. In addition, dedicated wetland buffers are shown on the Preliminary Plat. 5. Further construction details for the bioretention basins have been provided as required and included in the plans. Groundwater levels have also been addressed to verify that the infiltration basins will function as intended. 6. A permit in accordance with the requirements of the NPDES (National Pollution Discharge Elimination System) in accordance with the most recently adopted requirements of the MPCA and the City of Lino Lakes shall be obtained by the church, and shall be administered as required. Drainage calculations have been submitted for review. Review comments are as follows: 1. Existing condition runoff curve number information was not given. However, the narrative mentions existing row crops. A curve number of 61, pasture, good condition should therefore be used for the row crops. 2. The following information is missing and should be provided: Existing and proposed drainage area maps. • Existing and proposed hydrology information, including curve number computations and time of concentration computations. • 10 -year storm summary information. • High water levels for all pond, wetlands, and ditches on the grading plan. Low floor elevation of the Church building on the grading plan (the finished floor elevation is provided). Wastewater Treatment 1. In accordance with the City's Comprehensive Plan, the church is located in an area designated as rural, and the extension of sanitary sewer into this area is not anticipated in the immediate future. An on -site treatment system has therefore been proposed. Existing septic systems must be removed and/or abandoned in accordance with local and state requirements. 2. An on -site wastewater treatment system is proposed, based on the Onsite Wastewater Treatment System Final Design Report and Specifications for Eagle Brook Church, dated October 8, 2003, by Eco Systems Engineering, Inc. The system and Design Report have been reviewed by TKDA and the Anoka County Public Health Specialist. The system is acceptable and has been proven successfully in similar applications in Minnesota. The system as proposed exceeds design requirements.
