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: Portions of Dallas are within FEMA-designated floodplains associated with the Trinity River, White Rock Creek, Turtle Creek, and numerous tributaries. The Trinity River corridor, which runs through the heart of Dallas, is subject to periodic flooding and has been the focus of extensive flood control and corridor development initiatives. Properties in the floodplain require elevation, flood-resistant construction, and compliance with City of Dallas floodplain regulations. Stormwater management and drainage design are critical for development projects across Dallas. Dallas's rapid development and urbanization have increased impervious cover, making stormwater management and drainage design critical for new construction. The City of Dallas requires drainage plans, detention calculations, and erosion control for most development projects. Properties near the Trinity River, White Rock Creek, Turtle Creek, and other waterways may have additional floodplain development requirements. 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.
