Summary
Any regrading, fill placement, wall installation, dumping, excavating or mining in Islip is governed by the Subdivision and Land Development Regulations under Code of the Town of Islip § 68-409B, and the Town Engineer can require a site plan review before work starts to confirm adequate on-site drainage and no harm to surrounding properties.
B. The regrading, placement of fill, installation of walls, dumping of material, excavating, mining, or other similar disturbance of land shall be governed by the Subdivision and Land Development Regulations. Any of the above actions may be subject to a site plan review at the determination of the Town Engineer. Said determination shall be obtained prior to commencement of the action. The site plan review shall ensure that the action does not significantly alter the subject parcel so as to infringe on the health, safety and welfare of all citizens, does not negatively impact surrounding land uses and properties, and provides adequate on-site drainage to the satisfaction of the Town Engineer. C. Any person, firm, corporation or entity violating the above provisions shall be guilty of a misdemeanor and, upon conviction thereof, shall be punishable by fine or imprisonment, or both. If a violation is not removed or rectified to the satisfaction of the Town of Islip, then each day the violation continues shall constitute a separate offense under this section.

Full Breakdown
Chapter 68's Article XXXI sets Islip's minimum development standards for land disturbance, and §68-409B is the operative rule for grading, fill and drainage work that isn't simple land clearing (land clearing itself is a separate permit under §68-409A). Any regrading, placement of fill, installation of walls, dumping of material, excavating, mining, 'or other similar disturbance of land' is governed by the Town's Subdivision and Land Development Regulations, and the Town Engineer decides, before the work starts, whether the project needs a full site plan review.
1's separate duty to keep the parcel neat and litter-free, backed by the Town's right to enter after 30 days' written notice and bill the owner for cleanup. Because a New York county cannot zone, this town-level Engineer review, not a Suffolk County process, is what actually controls a homeowner's grading or drainage project.
Violations & Fines
A violation of Islip's grading, fill and drainage standards under § 68-409C is a misdemeanor, punishable by fine or imprisonment, or both; if the violation isn't corrected to the Town's satisfaction, each additional day it continues is a separate offense: a materially harsher exposure than the town's typical zoning fine schedule.
