General Illumination Requirements

The city of Peosta maintains specific regulations regarding how signs can be illuminated. These requirements help create visual consistency throughout the community while preventing light pollution.

All signs in Peosta must adhere to a maximum illumination standard of 0.3-foot candles over ambient light conditions. This ensures signs are visible without being excessively bright or distracting.

District-Specific Illumination Rules

Peosta's regulations vary by zoning district, reflecting different needs across the community:

Agricultural and Residential Districts (A-1, R-1, R-2, R-3): • "Ambient only" illumination is the standard permission • "Indirect and internal" illumination requires conditional use permits for non-residential and multi-family uses

Commercial Districts (C-1, C-2): • Both indirect and internal illumination are permitted for non-residential and multi-family principal uses • Electronic message signs are allowed

Residential Proximity Considerations

For businesses near residential areas, additional restrictions apply: • Lighted signs facing residential districts cannot be backlit • Must be placed at least 20 feet from the nearest residential district boundary

Construction and Performance Standards

All electronic message centers must:

• Be enclosed on all sides with finishes of brick, stone, stucco, powder-coated metal, or anodized aluminum • Include an automatic dimmer that reduces brightness during dusk or low-light conditions • Contain a default design that freezes the sign in one position if a malfunction occurs • Not exceed maximum sign area permitted for that sign type within its zoning district

Prohibited Features

• Blink, rotate, move, chase, flash, glare, strobe, scintillate, or distract traveling public • Include audio, pyrotechnic, or bluecasting (Bluetooth advertising) components • Resemble or suggest traffic control devices • Be used as portable or temporary signs
