Scope and Typical Deliverables
Drainage and floodplain engineering including site grading, drainage design and conveyance, detention evaluation, stormwater calculations, and floodplain development compliance. City-level context guides our approach; property-specific floodplain status, flood-zone determination, base flood elevation, and any required floodplain permits are verified for your specific site through FEMA mapping and the local floodplain administrator.
Deliverables depend on project scope, jurisdiction requirements, and site conditions.
Local Engineering and Permitting Considerations
Drainage and floodplain: Areas along Cottonwood Creek and tributaries may fall within FEMA-mapped floodplains. Verify the site flood zone before design. Tight urban sites and flash-rainfall runoff make drainage coordination common for Richardson redevelopment. Property-specific floodplain status, flood-zone determination, base flood elevation, and any required floodplain development permits are established at the property level through FEMA Flood Insurance Rate Maps and the local floodplain administrator; Alfa Engineering verifies these for your specific site as part of the engineering process.
