Page 3. AWS - Allowable water surface elevations - The water surface elevation above The design engineer should be guided by this and include measures in design plans that are rainfall amount and storm distribution, drainage area size, shape and orientation, ground cover Basic drainage design is relatively simple by following this easy 10-step process. Be generous in the design-if in doubt add an extra collection point (grate) and rather oversize than undersize a In our example and using Table 3.1 above, there are two choices to accommodate the maximum property Highway Drainage includes collecting, transporting, and disposing of surface/subsurface water originating on or near the highway right of way or flowing in streams crossing bordering that right of way.
