Revenue model

1. Professional engineering consulting services: Core revenue stream generated through on-call, task-order, and project-based engineering services contracts with municipal, county, state, and federal government clients. Contracts typically include a base term plus multiple option years (e.g., City of Lynchburg contract: one base year plus four option years; Loudoun County contract: one base year plus four one-year renewal options). Services are billed on a time-and-materials or fixed-price basis against negotiated scopes.
2. Technical Assistance Provider services (grants administration): Revenue earned as an approved Technical Assistance Provider under the National Fish and Wildlife Foundation (NFWF) Chesapeake Bay Stewardship Fund. Technical assistance grants are competitive based and awarded up to $40,000 per project, supporting stormwater, watershed planning, and monitoring/modeling engagements in Virginia, Maryland, West Virginia, and DC.
3. Training and certification services: Revenue from delivering WEF National Green Infrastructure Certification Program (NGICP) Train-the-Trainer workshops and related stormwater/water resources training engagements (e.g., Train-the-Trainer delivered in Austin, TX; NGICP classes for Fairfax County participants).

Core offering

GKY & Associates is a Virginia-based professional consulting firm that delivers water resources engineering, policy & planning, and environmental science services to government and business clients. The firm supports municipal, county, state, and federal clients with hydrologic/hydraulic modeling, MS4 permit compliance, TMDL action planning, stream restoration, dam safety, green infrastructure design, and National Green Infrastructure Certification Program (NGICP) training delivery. Engagements are procured through competitive proposals and on-call/task-order contracts, typically structured as multi-year base term plus option years.

Product overview

GKY & Associates delivers its offering as three integrated professional service lines rather than a single software product: Engineering Solutions, Policy & Planning Solutions, and Environmental Solutions. These core service lines are supported by cross-cutting offerings such as MS4 Compliance Services, 2D Stormwater Management Modeling, and the NGICP (National Green Infrastructure Certification Program) Training delivery, all drawn from the firm's base in Virginia water resources consulting. The Engineering Solutions line provides the technical backbone (hydrologic/hydraulic modeling with SWMM and HEC, 2D rain-on-grid modeling, stream restoration, dredging, and dam safety), while Policy & Planning Solutions supplies the regulatory and planning context (MS4 program support, TMDL action planning, stormwater financing feasibility, resilience planning), and Environmental Solutions provides the environmental science layer (stream assessments, water quality monitoring, green infrastructure inspection, BMP design). Together they form a unified consulting practice serving government and business clients across Virginia and beyond.
