Anoka, Minnesota 55303 Re' Meadowbrook Estates Revised Preliminary Plat Gentlemen: Since our letter of January 3t, 1980, on the above referenced plat, we have reviewed the revised preliminary plat, grading plan, drainage calculations and street plans. The preliminary plat has been revised to show temporary cul-de-sacs on the ends of 172nd Avenue N.W. and 174th Avenue N.W. and the pedestrian easement to the park has been moved to the west side of Lot 6, Block 2. In review of the grading plan and drainage calculations, we find that the pro- posed ditches and culverts will be adequate to handle the projected runoff. However, we would recommend that the culverts be lengthened to accommodate a 30 foot turning radius at street intersections. In review of the street plans we would recommend that a vertical curve on 174th Avenue N.W., 30 foot radii at 'street intersections, centerline elevations, culvert inverts and the temporary cul-de-sacs be added to the plans. Also con- struction specifications for the streets have not been submitted. We would recommend preliminary plat approval with the following contingencies: 1. All items discussed in this letter are corrected. The park dedication issue be resolved. -The planning commission indicated if the City Council decides to accept the park dedication as shown on the plat, a scenic easement following the 880 contour on the south side of Trott Brook should be granted to the City. We would also recommend that the pedestrian easement on the west side of Lot 6, Block 2 be dedicated as park land. keith caswell jr. ~J darrell schneider ¢~ richard sha
