312,000 SF Commercial Development in Dayton, OH

Q: How are stormwater requirements handled in Ohio?

Stormwater drainage is regulated by the Ohio EPA and local municipalities. We designed systems to handle high impervious surface loads while meeting water quality and discharge criteria. More at epa.ohio.gov.

RSP Engineers delivered full civil engineering design and site investigation for a 312,000 SF commercial development in Dayton, OH, including carwash, gas station, and site access planning.

Location: Dayton, OH

RSP Engineers provided comprehensive civil engineering services for a large-scale commercial development in Dayton, Ohio. The site includes three commercial buildings, a carwash, and a gas station—all designed to accommodate high-volume traffic and utility demands.

Project Overview

Location: Dayton, Ohio
Use: Retail and commercial services
Size: 312,000 square feet across 3 buildings + carwash + gas station
Scope: Full civil site design, utility capacity analysis, drainage planning, road access evaluation

What We Delivered

Our civil engineering team conducted a full feasibility and design package for the commercial development. From utility availability to road network compatibility, we prepared the site for construction and permitting success.

Environmental and Regulatory Coordination

Our engineers collaborated with Ohio environmental and transportation authorities to ensure site compliance:

Utility availability and capacity check with Dayton area public works
Road access feasibility in coordination with Ohio Department of Transportation (ODOT)
Stormwater drainage design following Ohio EPA and local codes
Environmental considerations for fueling infrastructure and water quality protection

Permitting Strategy

We developed a proactive permitting roadmap, including:

Civil construction documents tailored to Dayton municipal review processes
Infrastructure coordination with public agencies for water, sewer, and access approvals
Documentation to support traffic and stormwater permitting

Project Challenges

Complex Utility Demands: Large commercial square footage required extensive coordination with public and private utility providers
Stormwater Management for Impervious Surfaces: Carwash and gas station components needed high-efficiency drainage solutions and compliance with Ohio standards
Access Planning: Managing traffic flow and ingress/egress points to accommodate peak commercial traffic

Project Value

RSP Engineers delivered a complete civil engineering solution that positioned the developer for timely approvals and construction launch:

312,000 SF of commercial-ready design
Integrated carwash and gas station infrastructure
Efficient site circulation with long-term durability
Stormwater systems that meet Ohio’s evolving environmental criteria

Why It Matters

For commercial projects of this scale, utility capacity and traffic planning can make or break a site’s feasibility. RSP Engineers brought the technical depth and multi-agency experience to deliver a build-ready plan that supports retail success.

FAQ’s

Did RSP Engineers provide traffic and access analysis?

Yes. We evaluated road capacity and ingress/egress to support commercial vehicle volumes, in line with ODOT standards.

How are stormwater requirements handled in Ohio?

Stormwater drainage is regulated by the Ohio EPA and local municipalities. We designed systems to handle high impervious surface loads while meeting water quality and discharge criteria. More at epa.ohio.gov.

What types of commercial tenants is this project designed for?

The site layout supports general retail, quick-service tenants, fueling stations, and automotive services.

Can RSP Engineers manage projects outside Florida?

Yes. While based in Florida, RSP Engineers supports select national projects with full civil design, especially for commercial and industrial developments.
