Summary
Gulfport requires soil stabilization within five days of clearing or a construction halt under Appendix C of the city code. A land-disturbance permit is triggered once a project adds 20,000 square feet of impervious area, and even permit-exempt clearing under 10,000 square feet must still follow best management practices.
6.5.1 Soil stabilization shall be completed as soon as practical but not later than five (5) days after clearing or inactivity in construction. The city engineer, public works director, or building official may shorten this time frame based on projected weather conditions. 6.5.2 If seeding or another vegetative erosion control method is used, it shall become established within two (2) weeks and the building official or city engineer may require the site have another method in place until the soil is stabilized. ... 6.5.5 The entire site shall be stabilized to control erosion at the close of construction for any prolonged periods in excess of forty-eight (48) hours.

Full Breakdown
Appendix C, the city's erosion, sediment and post-construction stormwater ordinance adopted by Ordinance No. 2419, sets the construction-site rules. 1. 5 lays out the erosion control mechanics: soil stabilization must be completed no later than five days after clearing stops or construction goes inactive, though the city engineer, public works director or building official can shorten that window based on forecasted weather. Seeded or vegetated areas must establish cover within two weeks, stockpiles must be covered or stabilized at the end of every workday, and the entire site must be stabilized whenever construction pauses for more than 48 hours.
Revegetated areas must hold 75 percent survival with no bare patch larger than six inches square, repeated year over year until that threshold holds for a full year. Disturbances of one acre or more require a licensed contractor, engineer or certified erosion-control professional to prepare the plan, plus a post-construction stormwater management plan under Sections 5 through 7. The building code services division and engineering department inspect the work and can compel corrections when facilities are not built to the approved plan.
Violations & Fines
Section 9.2 makes a violation a misdemeanor: a fine up to $250 or 30 days in jail, or both, for a first offense. If the condition is not corrected after notice, each additional day is a separate offense punishable by up to $500 or 90 days in jail, or both. The building official and public works director enforce the ordinance and can issue citations and stop-work orders, and the city may seek an injunction or order restoration of disturbed land at the violator's cost.
