Summary
LDR Section 3.61.1 requires compost piles and any mechanical processing equipment to sit at least 300 feet back from every property line. That setback shrinks only when the adjoining lot is zoned Industrial or Major Power Generation Facility, where the district's ordinary structure setback from Table 3.12.2 applies instead.
Compost material piles and any associated mechanical processing equipment shall be set back at least 300 feet from any property line. However, where the abutting lot is designated Industrial or Major Power Generation Facility, the minimum setback for compost material piles and any associated mechanical processing equipment shall be the same as indicated for structures within the particular zoning district as set forth in section 3.12, Table 3.12.2.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 62 | Land Development Regulations: Supplement 62).
Full Breakdown
1 treats composting as a use with its own dimensional standard rather than folding it into the general accessory structure rules, stating that compost material piles and any associated mechanical processing equipment shall be set back at least 300 feet from any property line. That 300-foot figure applies everywhere in unincorporated Martin County regardless of zoning district, whether the compost operation sits on a residential, agricultural or commercial parcel. 2, which for districts like LI or GI runs as low as ten to fifteen feet.
Because the section reaches 'any associated mechanical processing equipment' along with the piles themselves, tub grinders, screening equipment and turning machinery used at a composting operation are held to the same 300-foot line as the raw material piles, not a lesser equipment setback. The rule was adopted by Ordinance No. 633 in September 2003 as part of the Land Development Regulations and has not been amended since.
Violations & Fines
A compost pile or processing equipment placed closer than 300 feet to a property line without qualifying for the industrial-adjacency exception is a Land Development Regulations violation, enforced by Growth Management code enforcement staff who can order the pile relocated or removed and refer noncompliance to the special magistrate for fines that accrue until the setback is met.
