Seeking Assistance With New Layout And SCARM

Hi everyone, a little background.  I had to dismantle my layout up north and want to begin new layout in Florida.  After several years I am ready to begin.  I am constructing my benchwork in sections beginning with 20-22 inch wide sections around the outside perimeter.  The thought process here is I will lay the track ballast and complete scenery before moving on to the next section.  Hope is to minimize reaching and wiring issues.  At 78 I'll need it to be as easy as possible.  I have numerous Lionel accessories which is the reason for the sidings, The bottom sidings are for the coal ramp and loaders.  My previous layouts have been all tubular and O22 switches.  I am planning all Ross switches and track.  I am a total novice at SCARM to say the least.  I have tried to piece together a SCARM plan but I am certain I need help with this.  I would appreciate any and all help / suggestions with the track plan and SCARM.  Thanks!
