A parabolic curve has a descending grade of -0.8% which meets an ascending grade of +0.4% at station 10+200. The maximum allowable change of grade per 20 m-station is 0.15. Elevation at station 10+200 is 204.60 m. Compute the elevation of the lowest point of the curve in meters. (Round off your final answer to three decimal places).
