Neff & Associates provides innovative professional site engineering services for a wide range of projects, working closely with the Client, Architects and other consultants developing construction documents while assisting the owner and their representatives in obtaining the necessary local and state governmental approvals. We also provide Bidding and Contract Documents necessary for construction and Construction Administration, as well as geotechnical, environmental or traffic engineering services.

Site development has changed considerably in recent years. With the ever increasing regulations and reviewing agency involvement, Neff & Associates stays ahead of the game to assure projects stay on track.


No project is too large or too small, with experience in subdivisions as small as 6 units, to over 1,500 units. Our experience is diverse with projects involving single family detached, attached, townhomes and apartments, from rural to city infill re-developments.

Once the roadway and utility infrastructure construction is complete, we work with the prospective home builders to develop individual house site plans necessary for obtaining building permits.


We welcome the challenge of a diverse project, while also enjoying the consistency that a national or local commercial chain can bring.  From a large multi-tenant site to a single user site, we can provide all your site development needs.


Whether the Industrial site begins with the development of infrastructure  necessary for the creation of individual sub lots, or with a sub lot ready for a specific user, we can meet your development needs.  We provide engineering and design services for both the overall Industrial development and the individual Industrial sites.


A Mixed-Use site may combine various residential, commercial, office or industrial sites to create a unique blend of uses. Neff & Associates has a great deal experience in solving many of the unique situations that arise with mixed use developments.


In the past Neff & Associates has performed consulting services for the counties of Cuyahoga, Lorain, Medina, Summit, Portage and Wayne. The Firm has been Engineers for the Cities of Seven Hills, Sheffield Lake, North Ridgeville, South Amherst, Streetsboro, Parma Heights and Middleburg Heights.

NPDES (National Pollution Discharge Elimination System) Site Monitoring

If your project requires periodic site storm water pollution reports during construction to meet the requirements of your NPDES permit, our office can provide the services necessary to generate the reports.

With The State of Ohio EPA Phase II requirements, municipalities are requiring yearly inspections of storm water management facilities. Whether the facility is publicly or privately owned, we can provide these yearly inspections for municipalities, private owners, and homeowner associations.
