Which of the following factors does NOT typically influence the design of raceway systems?

In the context of designing raceway systems, community input is not typically a primary factor influencing the technical or structural aspects of the raceway design itself. While community input may play a role in broader environmental considerations, such as permitting or broader project acceptance, the core design decisions are generally driven by more technical factors.

Government regulations provide guidelines and standards that must be adhered to in order to ensure safety and environmental compliance. Fish species selection is crucial because the specific needs of different species will dictate aspects of water quality, flow rates, and other environmental conditions within the raceway. The owner's preferences can significantly shape the design to align with specific operational goals, budget constraints, or aesthetic desires.

Thus, community input, while important in some contexts, does not usually have a direct impact on the detailed engineering and design considerations of raceway systems compared to the other factors listed.
