Summary
Construction and other regulated activity within 100 feet of Boston wetlands, streams, ponds, or the coast falls under Conservation Commission buffer-zone review, and Code § 7-1.4(G)(7) lets the Commission impose erosion and sedimentation design specifications, performance standards, and setbacks before work can proceed.
In reviewing activities within the buffer zone, the Commission shall presume the buffer zone is important to the protection of other resource areas because activities undertaken in close proximity have a reasonable probability of adverse impact, either immediately, as a consequence of construction, or over time, as a consequence of daily operation or existence of the activities. These adverse impacts from construction and use can include, without limitation, erosion, siltation, loss of groundwater recharge, poor water quality, loss of wildlife habitat, degradation of wetland plant habitat, alteration of hydrology and proliferation of invasive plants. The Commission may establish, in its regulations, design specifications, performance standards and other measures and safeguards, including setbacks, and other work limits for protection of such lands, including without limitation strips of continuous, undisturbed vegetative cover, unless the Commission determines, based on adequate evidence, that the buffer zone or part of it may be altered without harm to the values protected by the ordinance.

Full Breakdown
4(C)(1)(b) puts "lands adjoining these resource areas out to a distance of 100 feet, known as the buffer zone," within Conservation Commission jurisdiction. either immediately, as a consequence of construction, or over time," including erosion, siltation, loss of groundwater recharge, and degraded water quality. Under (G)(7), when reviewing buffer-zone work the Commission presumes the buffer zone is important precisely because of these construction-phase risks, and "may establish, in its regulations, design specifications, performance standards and other measures and safeguards, including setbacks, and other work limits," up to and including requiring strips of continuous, undisturbed vegetative cover, unless the applicant shows the area can be altered without harm.
To trigger review, an applicant files a written notice of intent by certified mail or hand delivery under (E), including plans showing the work's environmental effects and a Commission-set filing fee on top of the state Wetlands Protection Act fee; no work may start until the Commission issues an order of conditions and appeal periods run. A permit is valid three years and may be extended once for up to three more. This buffer-zone erosion-control authority applies only within jurisdictional resource areas and their 100-foot buffer, riverfront areas, and the Coastal and Inland Flood Resilience Zones, not to construction sites generally.
Violations & Fines
Enforcement runs through § 7-1.4(J): the Commission and its agents can enter land to inspect, and may enforce through violation notices, fines it sets itself, noncriminal citations under M.G.L. Chapter 40, Section 21D, and civil or criminal court action pursued by Corporation Counsel or the Police. Each day a violation continues, and each resource area or buffer zone affected, counts as a separate offense, and violators can be ordered to restore the land to its original condition.
