Civil Stamping Services
Apex Grid Engineering provides civil stamping services across 49 states and the District of Columbia — site and civil plan sets reviewed in responsible charge by licensed civil engineers and sealed for agency and permit review. Grading and earthwork, stormwater management with sealed drainage calculations, water/sewer/storm utilities, paving and access, and erosion control are engineered for each state's terrain, water rules, and agency requirements. Veteran-owned, 10+ licensed professional engineers, with agency comment responses included on every sealed civil set.

What civil stamping covers
Grading and earthwork plans, stormwater detention and retention design with sealed drainage calculations, water, sewer, and storm utility plans and profiles, paving and access design, and erosion-control documentation. DOT access permits, water-district approvals, and floodplain documentation are engineered into the set before sealing.

- Stormwater management with sealed drainage calculations
- Water, sewer, and storm utility plans and profiles
- Agency comment responses on the sealed civil set
Engineered for each state's terrain and water rules
Civil stamping follows the ground: karst regions need sinkhole-aware stormwater design, coastal states need floodplain and finished-floor compliance, arid states need water-district coordination, and every state runs its own construction stormwater program. Each state page below details the terrain, water, and agency realities the sealed site plan answers to.
Review-and-seal, not stamp-for-hire
Apex Grid's civil engineers define the scope, review the design basis, and perform or verify the civil work before sealing. Documents that cannot be verified to responsible-charge standards are not sealed. Boundary surveying is a separately licensed service and is not part of the civil seal — Apex Grid coordinates with the project's licensed surveyor.
Licensed coverage: 49 states plus the District of Columbia
