Draw me an elevation of a horse arena/menage

I am submitting a planning permit to council for a 30 x 60m outdoor horse arena to be built in our front paddock. A submission requirement is that I provide a scaled and fully dimensioned elevation plan set in a cross section of the approximate landscape. Included in the plan needs to be the following: 1. Black painted post and rail fence around the outside - set at 90 degrees (example 1 attached), incorporating: a. A single sleeper kick board around the bottom perimeter of the arena (with the exception of the gate areas, which will be left clear). The sleeper will be 200mm high x 50mm thick b. Upright posts are 120mm diameter and set at a spacing of 2400mm. They are 1250mm high. c. Top rail is flat and to align with the top of the post at 1250mm high. The rails are 150mm x 4mm. d. Centre rail is the same dimensions as top rail and set at 600mm down from the top of the post. e. Kick board and rails to be set arena side of post (internal to arena) 2. 3600mm timber boom style gates will be set at the centre of both short ends of the arena (example 2 attached) 3. Crushed rock base layer needs to be shown extending out of the arena by 1000mm and showing a depth of 100mm (example 3 attached – shows rock extension + cut) 4. Sand surface laying on arena showing a depth of 55mm 5. Beyond the crush rock border ground rises/ falls away and needs to show a battered edge covered in grass (see example 3 + example 4 hand drawn attached). Northern Elevation (looking from north) a. Upper elevation of 1500mm over 4000mm b. Lower degrade of 1500mm over 2000mm (example 4 hand drawn example attached)
