Instructions: $($a$.)$Use the grading criteria below to determine the elevation at each of the included markers. $($b$.)$Sketch $1\text{'}$ contour lines including where they jump the curb $($Label them.$)$ Criteria: Sidewalk adjacent to building should grade $1\%$ north to south. A $6"$ curb is proposed on the parking adjacent to the building. Combination of curb and gutter is proposed along the southern parking. The curb is $6"$ and the Gutter Pan is $2\text{'}$ Wide with $8\mathrm{.}33\%$ slope $(0\mathrm{.}17\text{'}$ vertical drop$)$ is propsoed along the southern parking. Curb ramp should be graded to ADA standards. Slope in ADA area $($shaded in grey$)$ is $1\mathrm{.}5\%$ from North to South and $1\%$ from West to East. For the rest of the parking lot, the slope from west to east is $2\%$ while the slope from North to south is $3\%.$ A curb inlet in proposed in the southeast corner of the parking lot.
