Record the intended finished area
A gravel project should begin with a drawing showing where existing material will be removed and where gravel will end. Include steps, drainage features and planting pockets. Ask your landscape professional how the design fits local wildfire guidance and other property needs rather than treating a material purchase as the whole plan.
Decide who maintains it
Discuss how fallen leaves, weeds and other accumulated material will be managed. Identify places hidden beneath shrubs or behind storage where inspection may be difficult. If you use a landscape crew, put these areas into its normal scope and agree how it reports conditions needing additional work. Keep the original drawing so later changes are easy to identify.
Map the remaining vegetation
A gravel area and a planted area should remain distinguishable in a WTG proposal. Show the boundaries and any planned changes; do not include all hardscape in an estimated treatment footprint. Ask which remaining vegetation can be assessed and which areas are excluded. A photograph taken after installation is more useful than an old listing image.
