'Apollo Landing /Equinox Page 2 March 4, 2005 City of Lino Lakes, Minnesota • 2. The Traffic Study has been reviewed and comments are provided within this memorandum. Generally, the data and conclusions provided in the report are not complete and the applicant has been requested to re -work the study. 3. The utility plan provided is not considered to be complete for construction purposes at this time. However, the utility plan as presented in concept is acceptable, and the comments provided herein are based upon the extent of plans completed to date. For example, storm sewer pipe sizes and structure invert and rim elevations are not provided. Standard utility plates, details, construction notes, provisions for erosion control, etc. must all eventually be provided as well. 4. The applicant has provided copies of correspondence to the Rice Creek Watershed District (RCWD). The applicant shall be responsible for assuring compliance with the RCWD accordingly. 5. The proposed site development is located adjacent to two County roadways. The plat and site plan will therefore require the review and approval of Anoka County, both for the plat itself and with regards to driveway and site access. It is likely that the County will have comments with regards to right of way dedication and access from Apollo Drive. 6. Drainage and utility easements must be provided on the Preliminary Plat as described herein. Drainage 1. The first floor elevations shown for the proposed buildings would appear to be acceptable based on the information provided. However, because actual building plans are not provided, it is not known if there are proposed to be basements, lower openings, etc. In accordance with City standards, the lowest floor elevation must meet the City's minimum requirement of 2 feet above the 100 year flood level, 4 feet above normal water elevations and groundwater, and at least one foot over the emergency overflow elevation. The actual overflow location and elevation for Pond 1 must be provided on the plan. 2. The full Hydro -Cad calculations must be provided by the applicant so that they can be verified further against the previous design parameters provided in the S.E.H. calculations. At this time, only portions have been provided. Support computations are also needed for the stage- discharge used in the Hydro -Cad model 3. Floor and /or any low opening elevations for the existing building directly to the west must be verified against the 100 -year and overflow elevations. Based on the information provided, it would appear that the 100 -year elevation of the pond may be higher than the building's low floor. 4. Per correspondence provided with RCWD, the applicant is incorporating the use of infiltration basins on the site prior to discharge to the pond. This will aid in providing effective stormwater management and water quality, as discharge from the pond into the storm sewer system running • south down Apollo Drive (as shown) shall be limited to the originally designed system limits. The plans must ultimately receive final approval of the Rice Creek Watershed District.
