Expansion often requires:
- Civil engineering plans
- Environmental studies (wetlands, flood plains)
- Soil testing
- Stormwater management plans
- Erosion control plans
- Traffic studies
- Architectural drawings (for cabins, bathhouses, clubhouses)
No builder will break ground without stamped engineering.
These plans alone can cost:
$15,000–$100,000 before the first shovel hits the ground.
