Complete the entry plaza grading plan on the next page. Use the spot elevations shown on the plan and the information below to define the grading between the building and the sidewalk. Criteria:No slope greater than $5\%$ except ramp which may be $8\mathrm{.}3\%,$ ramp landing $2\%$ maximum any directionNo slope less than $2\%$Stairs risers must be consistend and between $4"$ and $7"$ in heightStair treads must be between $12"$ and $15"$ in widthShow one extra 'tread' at the top and bottom of stair for railing locationsStairs may cross slope $\mathrm{.}01$ feet total. Treads may slope toward toe $($maximum $\mathrm{.}025\text{'}$ per ft$.)$Extend planters toward sidewalk as required to provide separation of stairsScale is $1"=10$'Show constant slope indicators, top and bottom of stair spot elevations, ramp elevations $($as required$),$ top and bottom of wall elevations, finished grades at building, and indicate all constant slopes:
