Sheehan, Graves Engineering o Request: Issue Order of Conditions. o Documents Presented: Colored site plan o Jurisdiction: Riverfront Area & Buffer Zone o Project Summary: The project includes the redevelopment of a previously developed RA. The project will include a reduction in developed areas, restoration, paving of an existing gravel parking lot and a storm-water management system to include a rain garden. o Staff Notes: • The project was continued from the Feb 2, 2020 meeting, as no DEP File # or comments had been received. The SCC had requested that globe thistle be removed from the planting list and that a split rail fence be incorporated into the project to prevent snow plowing into the restored RA. • DEP File # and comments have now been received. MassDEP recommends that proposed erosion control barriers be extended up along the western parcel boundary along the top of the wooden retaining wall to better protect adjacent resource areas and the neighboring parcel. Alternatively, if the applicant believes that the existing retaining wall will be sufficient to act as a barrier to potential sedimentation the applicant should provide sufficient information for Commission review. The 100 Buffer Zone does not appear to be rendered correctly on project plans. • Project has been revised to incorporate SCC and DEP comments. Revised plans have been received. o Staff Recommendations: • Staff recommends that the project be approved, as shown, with the following conditions: the SCC’s standard special conditions, a condition stating that: a Certificate of Compliance shall not be issued until after 2 growing seasons to ensure that the rain garden plantings have survived. The SCC reserves the right to require additional plantings to ensure achievement of 75% cover of plant species within two growing seasons; and the following perpetual conditions to include: • The property owner of record or designee, is responsible for the implementation of the Operation and Maintenance Plan. This shall be noted in the Certificate of Compliance and shall be an ongoing condition. • The applicants, owners, and their successors and assignees shall maintain all components of the stormwater management system including, but not limited to, all collection basins, grass swales, the rain garden, outlet structures, and other elements of drainage systems, in order to avoid blockages and siltation which might cause failure of the system and/or detrimental impacts to on-site or off-site resource areas, and shall maintain the integrity of vegetative cover on the site. • The Storm-water operations and maintenance plan and site records shall be stored on site to ensure employees are familiar with the demands of the plan. • Evidence of maintenance of the Storm-water Management system shall be provided to the Commission on an annual basis. An annual maintenance report shall be available to the Conservation Commission by June 1st of each year reporting on the maintenance and operation procedures which have been met for that year. This reporting requirement will follow the issuance of a Certificate of Compliance. • The Conservation Commission shall be notified in writing when any maintenance functions are required to be performed which may impact the wetlands, such as, but not limited to, placing backfill and repairing drains and terraces, removing accumulated sediments at the outfall pipe, prior to the work being conducted. • Stabilized slopes shall be maintained as designed and constructed by the property owner of record, whether “bioengineered” or mechanically-stabilized slopes. This shall be noted in the Certificate of Compliance and shall be an ongoing condition. • Rain garden maintenance: The property owner shall be responsible for the upkeep of the rain garden including the replacement of deceased plantings and as noted on the Storm-water O & M Plan. This condition shall survive the expiration of this Order, and shall be included as a continuing condition in perpetuity on the Certificate of Compliance. Plantings shall be reviewed annually by the owner/applicant and any plant materials requiring replacement shall occur. • Snow storage. Snow shall not be pushed into, or piled, in the rain garden or outside of the developed areas. This shall be noted in the Certificate of Compliance and shall be an ongoing condition. • The split rain fence, as shown on the plan, shall not be removed and shall be inspected and maintained in perpetuity. The split rail fence serves as a barrier to prevent snow plowing in the rain garden and within the adjacent vegetated areas.
