Sincere Apologies for reposting the question but anyone out there could assist.Thank you!!

If the Master plan level School project's (Multiple buildings within the development) site boundary will be enclosed by the 3 meter Wall (Location is in Middle East and no surrounding developments) please advise,
1. How shall I identify the Limit of site disturbance (40/25/15/10 feet?)
2. The surface parking will have the Solar PV panels as the Shading roof so do I have to treat them as parking garage and limit the site disturbance to 40 feet?
3. Enabling works temporary offices (Outside the building perimeter), shall I include or exclude them while defining the site disturbance boundary?
Thank you
