Site Plans for Largo Development and Construction Projects

Grading & Drainage for Sandy Soil

Largo's sandy soil demands careful drainage design. We perform site grading analysis, calculate drainage swales and retention areas, and design stormwater management systems that comply with Largo's standards. Sandy soil bearing capacity informs foundation design recommendations.

Commercial & Mixed-Use Site Design

Commercial projects on US 19 and downtown areas require site plans that align with overlay guidelines, parking calculations, landscape requirements, and traffic circulation. Our team designs compliant commercial sites that move quickly through City of Largo Building Division review.

Utility Coordination & Infrastructure

Water, sewer, electrical, and communications utilities must be properly routed, sized, and documented. We coordinate utility connections with site layout and provide infrastructure details for city review.

FAQs

What's included in a site plan?

A complete site plan includes property boundary, existing and proposed topography, building footprint, parking layout, utilities (water, sewer, electrical, communications), drainage and grading design, landscaping, site dimensions, and code compliance notes. HB Design and Engineering prepares comprehensive site plans ready for LCAP submission.

How do you handle stormwater management in Largo?

Largo's stormwater standards require retention or treatment for runoff from impervious surfaces. We calculate required retention volumes, design retention ponds or swales, and ensure drainage flows from roofs, parking areas, and buildings meet Largo code. Sandy soil drainage characteristics inform the design we coordinate approach.

What about parking requirements on my Largo site?

Largo has parking requirements that vary by use type and square footage. Commercial, residential, and mixed-use projects each have specific standards. We calculate parking needs, optimize parking layout, and document code compliance on the site plan.

Do I need a topographic survey for my site plan?

A topographic survey is highly recommended and often required for projects with complex grading or drainage. It provides accurate existing elevation data that informs grading and drainage design. HB Design and Engineering can coordinate survey work or work with surveys you've already obtained.

How does site design affect utilities?

Site design determines where utilities connect to buildings, how water and sewer are routed, electrical service location, and stormwater discharge points. Our site engineers coordinate with utility companies and design utility infrastructure that integrates with site layout.

What if my project is on the US 19 corridor?

US 19 commercial overlay district has specific site design requirements: setbacks, landscape buffers, parking placement, and architectural character compatibility. Our site plans address these standards from the start, ensuring quick City of Largo Building Division approval.
