Locally, the data is of c&orsiderably poorer quality. <br />ti r should carefully determine the pled to -place accuracy <br />and fitness of these data for your particula purposes. For many <br />purposes a site- and use-spedfic field su t ey will be necessary. <br />The accuracy specification is based on a'fequired Root Mean <br />Square Error (RMSE) 'Bare Earth' vertical accuracy of 30 cm <br />for flat areas in the complete data set adjusted from the 15 cm <br />RMSE in the FEMA specification to y?b cm to accommodate <br />the dense vegetation cover in the Pgacific Northwest). <br />t <br />Current Roadway <br />Current Ordinary High Water <br />Medium Sea Level Rise Scenario (1ft) <br />Appendix L: Climate Change Background <br />
