A.
Areas subject to protection under the Sturbridge Wetlands Bylaw and its Regulations include all resource areas protected under the Wetlands Protection Act and its regulations: bank, land under water bodies and waterways, bordering vegetated wetlands, riverfront area, land subject to flooding and lands within the 100-foot buffer zone of bank and bordering vegetated wetland. In addition, under the Sturbridge Wetlands Bylaw and Regulations, the following resource areas are subject to protection: seasonal wetlands, vernal pools, lands subject to flooding or inundation and lands within the 200-foot buffer zone of any of the aforesaid jurisdictional areas under the Wetlands Protection Act or Sturbridge Wetland Protection Bylaw, whether or not they border surface waters. For the purpose of this document, "resource areas identified" or "resource areas protected" refer to the above-stated areas.
B.
Resource area interests include those listed in the Wetlands Protection Act and its regulations: protection of public and private water supply, protection of groundwater supply, flood control, storm damage prevention, prevention of pollution, protection of fisheries and protection of wildlife habitat (protection of land containing shellfish is not applicable, since this refers to "land under the ocean"). The following five additional interests apply to the Sturbridge Wetlands Bylaw and Regulations: erosion and sedimentation control, protection of water quality, protection of rare species habitat, protection of recreational values and protection of agriculture and aquiculture activities.
C.
Activities within the areas subject to protection, as well as activities within the 200-foot buffer zones to areas subject to protection, and 500-foot buffer zone of areas with 8% slope or greater which will remove, fill, dredge, build upon, degrade, discharge into or otherwise alter said resource areas and buffer zones fall under the jurisdiction of the Sturbridge Conservation Commission ("the Commission"). Said activities, if in an area subject to the Wetlands Protection Act, require a public hearing for prior review and approval by the Commission to insure there will be no significant adverse impact to the resource area. Said activities, if in an area subject to protection under the Sturbridge Wetlands Protection Bylaw and Regulations, require review and approval during a public meeting of the Conservation Commission to insure there will be no significant adverse impact to the resource areas and buffer zones specifically covered by these regulations.
D.
Activities undertaken in close proximity to wetlands and other resource areas have a high likelihood of adverse impact upon the wetland or other resource, either immediately, as a consequence of construction or over time, as a consequence of daily operation or other activities. These adverse impacts from construction and use can include but are not limited to erosion, siltation, loss of groundwater recharge, disruption of hydrologic connections, nutrient runoff, poor water quality, harm to wildlife habitat or disruption of wildlife habitat corridors. The Commission may therefore require that the applicant maintain a strip of continuous, undisturbed vegetative cover in part or all of the 200-foot area and set other conditions on this area, unless the applicant provides evidence deemed sufficient by the Commission that the area or part of it may be disturbed without harm to the values protected by the law.
E.
Work and activity within 200 feet of wetlands and resource areas should be avoided and discouraged and reasonable alternatives pursued. Accordingly, the Conservation Commission shall begin with the presumption that lands within 200 feet of the resource areas previously discussed in this section are best left in an undisturbed and natural state.
F.
Disturbance of vegetation or soils within 25 feet of a resource area creates direct observable impacts to the resource area, including but not limited to those stated elsewhere in these regulations. The minimum strip of continuous undisturbed vegetative cover for any and all resource areas is 25 feet from the outermost edge of the resource area in all directions. The twenty-five-foot buffer is to be considered a "no disturb" buffer.
G.
Any structures less than 50 feet from a resource area can create temporary construction and long-term "normal daily use" impacts within the twenty-five-foot buffer. The minimum distance for a new structure will be 50 feet from any resource area. The fifty-foot "no structure" buffer will not apply to any structure existing prior to the adoption of these regulations. However, structures being removed and replaced must comply with the regulations in effect at the time of the reconstruction. For preexisting structures within the fifty-foot buffer, which are not being removed but for which the footprint is changing, any increase in footprint must take place no closer than 50 feet to the resource area.
H.
Waivers.
(1)
The Commission shall have the power to issue a waiver to perform activities as described in § 365-1.1 of this Town of Sturbridge Wetlands Bylaw Regulation, after said applicant files a notice of intent (if proposed activities are subject to the Wetlands Protection Act) with the Commission and the Commission conducts a public hearing. If said activity is subject to the Sturbridge Bylaw and Regulations, the applicant shall file a wetland bylaw permit application. Such waiver shall be set forth by the issuance of an order of conditions or wetland bylaw permit by the Commission. In order for the Commission to issue a waiver with respect to a particular project, the Commission must find, based on clear and convincing evidence set forth by the applicant, that owing to circumstances relating to soil conditions, hydrological conditions, topography of such land and especially affecting such land but not generally affecting wetlands within the Town, a literal enforcement of the provisions of this bylaw would involve substantial hardship, financial or otherwise, to the applicant, and that desirable relief may be granted without detriment to the values protected by the Town Wetlands Bylaw and these regulations and without substantially derogating from the extent or purpose of the Town Wetlands Bylaw and these regulations.
(2)
A waiver (as stated above) to the fifty-foot "no structure" buffer and the twenty-five-foot "no disturb" buffer may also be granted to applicants under the following circumstances: the area is already previously disturbed and the proposed project will improve the protection to the resource area; or the applicant can prove with documented evidence that there are no other substantially equivalent alternatives available. Said applicant must show that measures will be incorporated into the project to ensure that there will be no significant adverse impact to the resource area and must provide additional protection at a ratio of 2:1 to the value of the resource buffer being altered.
(3)
Single-family homes, existing prior to the adoption of these regulations, on small, lakefront lots may, on a case-by-case basis, be granted a partial waiver from the twenty-five-foot and fifty-foot buffer requirements. Granting of a waiver will be based on the following minimum criteria;
(a)
A plan providing for 2:1 mitigation for area disturbed. Said plan shall include. but not be limited to, plantings of naturally occurring vegetation, along the lakefront, which increase the vegetative cover and decrease erosion within the first twenty-five-foot buffer to the lake.
(b)
Any proposed disturbance shall be minimized and shall be located at the furthest possible distance from the lake.
(c)
Said plan shall prioritize sedimentation and erosion control improvement issues along the most disturbed and vulnerable portions of the lakefront.
(d)
Mitigation must occur within the twenty-five-foot buffer first and work outward until the required mitigative effects are achieved.
(e)
Any additional structure in the fifty-foot buffer must be minimized and placed as far from the lake as possible.
(f)
Walkways and pathways within the fifty-foot buffer shall utilize pervious materials, to be approved by the Commission.
(4)
The Commission may impose conditions, safeguards and limitations in a waiver permit to protect or further the interests protected by the Sturbridge Wetlands Bylaw and Regulations. It should be understood that waivers are intended to be granted only in rare and unusual cases and are issued at the sole discretion of the Commission.
I.
At the discretion of the Commission, concrete bounds or other appropriate permanent markers clearly delineating the twenty-five-foot "no disturb" buffer, or any alternative approved-width "no disturb" buffer the Commission imposes for each property, are to be installed prior to the start of any work on-site.
