The exact boundaries of the District may be defined by the 100-year base flood elevations shown on the FIRM and further defined by the Norfolk County Flood Insurance Study (FIS) report dated July 17, 2012. The FIRM and FIS report are incorporated herein by reference and are on file with the Engineering Division of the Department of Public Works.

§ 9.1.3 Base flood elevation.

The base flood elevation shall be the level of flooding having a 1% chance of being equaled or exceeded in any given year, as designated on FEMA FIRMs. In the absence of such designation, the base flood elevation shall be determined by the Inspector of Buildings based upon the best available information regarding flood hazards, including any available United States Geological Survey, Natural Resources Conservation Service and Corps of Engineers studies, after seeking and obtaining the recommendation of the Town Engineer.

1. Base flood elevation data is required for subdivision proposals or other developments greater than 50 lots or five acres, whichever is the lesser, within unnumbered A Zones.

§ 9.1.4 Floodway data.

In Zones A and AE, along watercourses that have not had a regulatory floodway designated, the best available federal, state, local or other floodway data shall be used to prohibit encroachments in floodways which would result in any increase in flood levels within the community during the occurrence of the base flood discharge.

§ 9.1.5 Encroachments of proposed development.

Within the floodway designated on the FEMA Flood Insurance Rate Map, no encroachments (including fill, new construction, substantial improvements, or other development) shall be allowed unless it is demonstrated by the applicant that, as a consequence of compensating actions he is undertaking, his proposed development will not result in any increase in flood levels within the Town during a flood to the base flood elevation.

§ 9.1.6 Reference to existing state regulations.

All development in the FPOD, including structural and nonstructural activities, whether permitted by right or by special permit, must be in compliance with MGL c. 131, § 40, and with the following:

1. Sections of the Massachusetts State Building Code (780 CMR) which address floodplain and coastal high-hazard areas;

2. Wetlands Protection Regulations, Department of Environmental Protection (DEP) (currently 310 CMR 10.00);

3. Adopting Inland Wetland Orders, DEP (currently 310 CMR 13.00);

4. Minimum Requirements for the Subsurface Disposal of Sanitary Sewage, DEP (currently 310 CMR 15.500 et seq.);

5. Any variances from the provisions and requirements of the above-referenced state regulations may only be granted in accordance with the required variance procedures of these state regulations.

§ 9.1.7 Special permit.

The Zoning Board of Appeals may grant a special permit to waive the requirements of § 9.1.5 above. Such special permit may be granted only in the case of structures such as boat houses which require waterfront location and are not continuously used for human occupancy, or in the case of development on a lot of less than 1/2 acre which is surrounded by existing nonconforming structures, in either case provided that all of the following are shown:

1. Good and sufficient cause;

2. Failure to allow the departure would result in exceptional hardship to the applicant;

3. Allowing the departure will not result in increased flood heights, additional threats to public safety, extraordinary public expense, create nuisances, cause fraud on or victimization of the public, or conflict with other bylaws or regulations;

4. The departure is the minimum necessary, considering the flood hazard, to afford relief.

5. A waiver may also be granted for the reconstruction, rehabilitation, or restoration of structures listed on the National Register of Historic Places.

§ 9.1.8 Required notifications.

Residential apartments on the first floor of a structure which does not front on a public way shall be permitted only at the discretion of the Planning Board.

§ 9.3.4 Density.

The minimum density for MUOD developments shall be 20 units per acre, provided the development has access to or creates a shared system and treatment works as defined by 310 CMR 15.00. In the absence of a shared system and treatment works, the minimum density may be waived, subject to the special permit. The maximum number of units shall be limited by the more restrictive of the following factors: the number of full-sized parking spaces which could be provided and/or full compliance with the Board of Health and zoning wastewater management regulations, or Conservation Commission Wetlands Regulations.

§ 9.3.5 Wastewater.

A plan for the treatment of wastewater from a proposed development in the MUOD must be approved by the Board of Health in accordance with all applicable regulations.

§ 9.3.6 Height of structures.

All new construction in the MUOD shall neither exceed four stories nor a building height of 45 feet. Accessories and architectural features extending above the roofline may not exceed a height of 50 feet.

§ 9.3.7 Off-street parking regulations.

A minimum of one space per residential unit shall be provided, in addition to parking required for retail and business uses pursuant to § 6.1. With the approval of the Planning Board, up to 25% of the total number of residential parking spaces for a development located within a 1/2 mile of the train station may be used to meet the required parking for retail and business uses, and up to 50% of the total number of residential parking spaces for a development located more than 1/2 mile from the train station may be used to meet the required parking for retail and business uses, where it can be demonstrated that the hours of operation for retail and business uses at the development will be during daytime hours only.

1. In order to provide for better site design, up to 25% of the total number of parking spaces may, at the discretion of the Planning Board, be allocated for compact cars with dimensions of eight feet by 18 feet. Such spaces shall be clearly designated for compact cars only. Compact spaces cannot be applied in calculating the density of residential units, but they may be used to meet minimum open space requirements and provide for between site design and stormwater drainage.

2. Off-site parking may not be counted toward the requirements for residential units, but may be counted toward nonresidential parking requirements. Street parking, as with other publicly owned parking spaces within 400 feet of the site, may be counted toward the nonresidential parking requirements.

3. Multi-level parking may be allowed, not to exceed two levels, if determined by the Planning Board to be appropriate. Such parking may be shared with others off-site, provided it is within 400 feet of the site and the Planning Board is provided with acceptable written proof.

The Sharon Commons Smart Growth Overlay District, hereinafter referred to as the "SCSGOD," is an overlay district having a land area of approximately 11.55 acres, being portions of Assessor's Map 47, Lot 37 and Assessor's Map 57, Lots 17, 18 and 21, that is superimposed over the underlying zoning district, as shown on the Zoning Map as set forth on the map entitled "Attachment 1-1: Locator Map," but only including Subzones A and B, and on the two maps entitled "Attachment 5-4: Smart Growth Zoning Map," all maps being dated September 23, 2008. These maps are hereby made a part of the Zoning Bylaw and are on file in the Office of the Town Clerk.

2. Underlying zoning. The SCSGOD is an overlay district superimposed on all underlying zoning districts. Except as limited herein, the underlying zoning shall remain in full force and effect.

3. Applicability of SCSGOD. In accordance with the provisions of MGL c. 40R and 760 CMR 59.00, an applicant for a project located within the SCSGOD may seek plan approval in accordance with the requirements of this section. In such case, then notwithstanding anything to the contrary in this Zoning Bylaw, such plan approval shall not be subject to any other provisions of this Zoning Bylaw, including limitations upon the issuance of building permits for residential uses related to a rate of development or phased growth limitation or to a local moratorium on the issuance of such permits, or to building permit or dwelling unit limitations, including but not limited to any rate-of-development limitations provided in this bylaw. When a building permit is issued for any project approved in accordance with this § 9.4, the provisions of the underlying district(s) shall no longer be applicable to the land shown on the site plan which was submitted pursuant to this § 9.4 for such project.

§ 9.4.4 Affordable housing.

1. Marketing plan. Prior to granting plan approval for housing within the SCSGOD, an applicant for such approval must submit a narrative document and marketing plan that establishes that the proposed development of housing is appropriate for diverse populations, including households with children, other households, individuals, households including individuals with disabilities, and the elderly. These documents in combination, to be submitted with an application for plan approval pursuant to this section, shall include details about construction related to the provision, within the project, of units that are accessible to the disabled. The marketing plan must be approved by DHCD prior to the issuance of a building permit for a Development project.

2. Number of affordable housing units. For all projects, not less than 20% of the total housing units constructed in a project shall be affordable housing. For all projects where the affordable units proposed are rental units, not less than 25% of total housing units in any building containing rental units shall be affordable housing; provided, however, that 20% of such units may be affordable where restricted to households earning less than 50% of area median income. For purposes of calculating the number of units of affordable housing required within a project, any fractional unit shall be deemed to constitute a whole unit.

3. Requirements. Affordable housing shall comply with the following requirements:

a. For an affordable rental unit, the monthly rent payment, including utilities and parking, shall not exceed 30% of the maximum monthly income permissible for an eligible household, assuming a family size equal to the number of bedrooms in the unit plus one, unless other affordable program rent limits approved by the DHCD shall apply.

b. For an affordable homeownership unit, the monthly housing payment, including mortgage principal and interest, private mortgage insurance, property taxes, condominium and/or homeowners' association fees, insurance, and parking, shall not exceed 30% of the maximum monthly income permissible for an eligible household, assuming a family size equal to the number of bedrooms in the unit plus one.

c. Affordable housing required to be offered for rent or sale shall be rented or sold to and occupied only by eligible households.

d. The SCSGOD shall not include the imposition of restrictions on age upon the entire district, but the development of specific projects within the SCSGOD may be exclusively for the elderly, persons with disabilities, or for assisted living, provided that any such project shall be in compliance with all applicable federal, state and local fair housing laws and regulations and not less than 25% of the housing units in such a restricted project shall be restricted as affordable housing.

e. At least 10% of the affordable housing units shall be handicapped-accessible.

4. Design and construction. Units of affordable housing shall be finished housing units. Units of affordable housing shall be dispersed throughout the development of which they are part and be comparable in initial construction, quality and exterior design to other housing units in the development. The total number of bedrooms in the affordable housing shall be at least proportionate to the total number of bedrooms in all the units in the development project of which the affordable housing is part.

5. Affordable housing restriction. Each unit of affordable housing shall be subject to an affordable housing restriction which is recorded with the appropriate Registry of Deeds or District Registry of the Land Court and prior to such recording has been approved by DHCD. Such affordable housing restriction shall contain the following:

a. Specification of the term of the affordable housing restriction, which shall be the maximum period allowed by law but not less than 99 years;

b. The name and address of a monitoring agent with a designation of its power to monitor and enforce the affordable housing restriction;

c. A description of the affordable homeownership unit, if any, by address and number of bedrooms; and a description of the overall quantity and number of bedrooms and number of bedroom types of affordable rental units in a project or portion of a project which are rental. Such restriction shall apply individually to the specifically identified affordable homeownership unit and shall apply to a percentage of rental units of a rental project or the rental portion of a project without specific unit identification;

d. Reference to a housing marketing and resident selection plan, to which the affordable housing is subject, and which includes an affirmative fair housing marketing program, including public notice and a fair resident selection process. If approved by DHCD, the housing marketing and selection plan may provide for preferences in resident selection for the affordable housing units. The plan shall designate the household size appropriate for a unit with respect to bedroom size and provide that the preference for such unit shall be given to a household of the appropriate size;

e. A requirement that buyers or tenants will be selected at the initial sale or initial rental and upon all subsequent sales and rentals from a list of eligible households compiled in accordance with the housing marketing and selection plan;

f. Reference to the formula pursuant to which rent of a rental unit or the maximum resale price of a homeownership will be set;

g. A requirement that only an eligible household may reside in affordable housing and that notice of any lease or sublease of any unit of affordable housing shall be given to the monitoring agent;

h. Provision for effective monitoring and enforcement of the terms and provisions of the affordable housing restriction by the monitoring agent;

i. Provision that the restriction on an affordable homeownership unit shall run in favor of the monitoring agent and the Town, in a form approved by Municipal Counsel, and shall limit initial sale and all subsequent resales to and occupancy by an eligible household;

j. Provision that the restriction on affordable rental units in a rental project or rental portion of a project shall run with the rental project or rental portion of a project and shall run in favor of the monitoring agent and the Town, in a form approved by Municipal Counsel, and shall limit rental and occupancy to an eligible household;

k. Provision that the owner(s) or manager(s) of affordable rental unit(s) shall file an annual report to the monitoring agent, in a form specified by that agent, certifying compliance with the affordability provisions of this bylaw and containing such other information as may be reasonably requested in order to ensure affordability;

l. A requirement that residents in affordable housing provide such information as the monitoring agent may reasonably request in order to ensure affordability.

6. Monitoring agent. A monitoring agent, which may be the local housing authority, or other qualified housing entity shall be designated by the PAA as the monitoring agent for all projects in the SCSGOD. In a case where the monitoring agent cannot adequately carry out its administrative duties, upon certification of this fact by the PAA or by DHCD, such duties shall devolve to and thereafter be administered by a qualified housing entity designated by the PAA. In any event, such monitoring agent shall ensure the following, both prior to issuance of a building permit for a project within the SCSGOD, and on a continuing basis thereafter, as the case may be:

a. Prices of affordable homeownership units are properly computed; rental amounts of affordable rental units are properly computed;

b. Income eligibility of households applying for affordable housing is properly and reliably determined;

c. The housing marketing and resident selection plan conforms to all requirements and is properly administered;

d. Sales and rentals are made to eligible households chosen in accordance with the housing marketing and resident selection plan, with appropriate unit size for each household being properly determined and proper preference being given; and

e. Affordable housing restrictions meeting the requirements of this section are recorded with the proper Registry of Deeds.

f. Housing marketing and selection plan. The housing marketing and selection plan shall make provision for payment by the project applicant of reasonable costs to the monitoring agent to develop, advertise, and maintain the list of eligible households and to monitor and enforce compliance with affordability requirements, as set forth herein.

7. Phasing. The PAA, as a condition of any plan approval, may require a project to be phased in order to mitigate any extraordinary adverse project impacts on nearby properties. For projects that are approved and developed in phases, the PAA shall assure the required number of affordable housing units in the project. Such assurance may be provided through use of the security devices referenced in MGL c. 41, § 81U, or through the PAA's withholding of certificates of occupancy until proportionality has been achieved. No density bonus payment will be received by the Town until such proportionality has been achieved by the issuance of occupancy permits for the affordable housing units in the project.

8. Computation. Prior to the granting of any plan approval of a project, the applicant must demonstrate, to the satisfaction of the monitoring agent, that the method by which such affordable rents or affordable purchase prices are computed shall be consistent with state or federal guidelines for affordability applicable to the Town.

9. No waiver. Notwithstanding anything to the contrary herein, the affordability provisions in this § 9.4.4 shall not be waived.

§ 9.4.5 Permitted and prohibited uses.

1. As-of-right uses. The following uses shall be permitted as-of-right in the SCSGOD:

4. Plan approval. An application for plan approval that has been submitted to the Town Clerk pursuant to §§ 9.4.10 to 9.4.12 shall not be subject to any Design Standard that has not been approved by DHCD and filed with the Town Clerk.

§ 9.4.14 Decision.

1. Waivers. Except where expressly prohibited herein, upon the request of the applicant the plan approval authority may waive dimensional and other requirements of this section, including the Design Standards, in the interests of design flexibility and overall project quality, and upon a finding of consistency of such variation with the overall purpose and objectives of the SCSGOD, or if it finds that such waiver will allow the project to achieve the density, affordability, mix of uses, and/or physical character allowable under this section.

2. Plan review. An application for plan approval shall be reviewed for consistency with the purpose and intent of this section, and such plan review shall be construed as an as-of-right review and approval process as required by and in accordance with the Enabling Laws.

3. Plan approval. Plan approval shall be granted by a simple majority where the PAA finds that:

a. The applicant has submitted the required fees and information as set forth herein; and

b. The project and site plan meet the requirements and standards set forth this section, or a waiver has been granted therefrom; and

c. Extraordinary adverse potential impacts of the project on nearby properties have been adequately mitigated by means of suitable conditions.

4. Plan disapproval. A site plan may be disapproved only where the PAA finds that:

a. The applicant has not submitted the required fees and information as set forth herein; or

b. The project and site plan do not meet the requirements and standards set forth this section, or a waiver has not been granted therefrom; or

c. It is not possible to adequately mitigate significant adverse project impacts on nearby properties by means of suitable conditions.

5. Form of decision. All decisions of the PAA shall be by a majority vote of the members present and voting. The PAA shall issue to the applicant a copy of its decision containing the name and address of the owner, identifying the land affected, and the plans that were the subject of the decision, and certifying that a copy of the decision has been filed with the Town Clerk and that all plans referred to in the decision are on file with the PAA. If 20 days have elapsed after the decision has been filed in the office of the Town Clerk without an appeal having been filed or if such appeal, having been filed, is dismissed or denied, the Town Clerk shall so certify on a copy of the decision. A copy of the decision shall be provided to the Inspector of Buildings. A copy of the decision or application bearing such certification shall be recorded in the Registry of Deeds for the county and district in which the land is located and indexed in the grantor index under the name of the owner of record or recorded and noted on the owner's certificate of title. The fee for recording or registering shall be paid by the applicant.

§ 9.4.15 Change in plans after approval by PAA.

1. Minor change. After plan approval, an applicant may apply to make minor changes involving minor utility or building orientation adjustments, or minor adjustments to parking or other site details that do not affect the overall buildout or building envelope of the site, or provision of open space, number of housing units, or housing need or affordability features. Such minor changes must be submitted to the PAA on redlined prints of the approved plan, reflecting the proposed change, and on application forms provided by the PAA. The PAA may authorize such changes at any regularly scheduled meeting, without the need to hold a public hearing. The PAA shall set forth any decision to approve or deny such minor change by motion and written decision, and provide a copy to the applicant for filing with the Town Clerk. A copy of the decision shall be provided to the Inspector of Buildings.

§ 9.5 Recreation and Residential Overlay District (RROD).

§ 9.5.1 Purpose.

The purpose of the Recreation and Residential Overlay District is to enhance the public welfare by creating a viable residential community with the amenities afforded by an on-site golf course, multiuse clubhouse, and passive open space areas.

§ 9.5.2 Definitions.

See "Recreation and Residential Overlay District" in Section 11.0.

§ 9.5.3 Eligibility.

The site must be located within the Recreation and Residential Overlay District on the Zoning Map, Town of Sharon, Massachusetts.[1]

[1] Editor's Note: Said map is included as an attachment to this chapter.

§ 9.5.4 Site plan review.

Recreation and Residential Overlay District projects require site plan approval from the Planning Board pursuant to § 10.6.

§ 9.5.5 Application.

Recreation and Residential Overlay Districts shall be considered as superimposed on underlying zoning districts. A Recreation and Residential Overlay District project shall conform to all other provisions of this bylaw, including other overlay districts, except to the extent that use, dimensional, parking, loading, and design requirements are set forth in this section. The Recreation and Residential Overlay District shall not restrict owners' rights relative to the underlying zoning district, including other overlay districts. However, if an applicant elects to develop a Recreation and Residential Overlay District project, as evidenced by obtaining a building permit for any principal structure or proceeding with land disturbance for any site improvement requiring site plan authorization pursuant to this section, then all development within the total Recreation and Residential Overlay District project shall conform to the use, dimensional, parking, and loading requirements of this section. To the extent there are inconsistencies between provisions of this section and the provisions of any underlying district, the provisions of this section shall govern.

§ 9.5.6 Active open space requirements.

Each application for site plan approval for a Recreation and Residential Overlay District project must provide a golf course that includes at least 18 holes having an average length exceeding 250 yards.

§ 9.5.7 Restriction.

Prior to issuance of an initial building permit for a Recreation and Residential Overlay District project, the property owner shall cause a restriction to be recorded in the Registry of Deeds or the Land Court in a form acceptable to Town Counsel prohibiting any residential use or construction of residential living units on the golf course lot and on the multiuse clubhouse lot. Should the golf course be abandoned or should its owner determine that continued operation is considered not to be viable, ownership of the golf course lot shall be conveyed to the Town of Sharon in fee simple at no cost within 90 days of such abandonment or determination. If the golf course is not used for normal golfing purposes for at least 240 days in any calendar year, it shall create a rebuttable presumption that the course has been abandoned; provided, however, that the 240-day period shall not include any non-use caused by the following, without limitation, and as examples only: weather delays, redesign of the golf course, or unanticipated and unusual water problems and other natural disasters.

§ 9.5.8 Phasing.

Recreation and Residential Overlay District projects may be developed in two or more phases, provided that each phase is independent and self-sufficient, providing adequate access and utility service for all buildings and uses included in the phase and in any prior phases. Plans for phasing shall be shown on the site plan.

§ 9.5.9 Sureties.

The property owner shall post lot covenants, instruments of surety, insurance policies, letters of credit or similar securities as provided in the Town's subdivision regulations (hereinafter "instruments") to be provided prior to the issuance of any building permits for each phase of the project, if applicable, to the benefit of the Town of Sharon in a form acceptable to Town Counsel in amounts to be reasonably established by the Planning Board shall be posted in order to secure incomplete site infrastructure improvements. Release mechanisms for building permits shall be as provided in the Planning Board's subdivision regulations for release of lots.

§ 9.5.10 Green development.

All site improvements shall incorporate the green development principles of energy efficiency and sustainability by including those Leadership in Energy and Environmental Design (LEED) Plan for Neighborhood Development (LEED ND: Plan) strategies set forth herein in the planning and design of the total Recreation and Residential Overlay District project. Building design shall not be subject to the requirements of this section and inclusion of at least one certified green building shall not be required. LEED strategies to be included in the planning and design of the Recreation and Residential Overlay District project are as follows:

1. Open space shall be preserved by restricting the total lot area for two-family dwelling and the multiuse clubhouse use and requiring a permanent restriction on development of the golf course lot.

2. The development footprint shall be reduced by providing a compact two-family neighborhood plan that offers an effective alternative to low-density sprawling single-family development.

3. Water resources shall be protected by restricting development within the Groundwater Protection District of the Zoning Bylaw.

4. Housing diversity shall be increased by providing two-family dwellings, thereby increasing housing choices for Town residents.

5. Infrastructure efficiency shall be facilitated by providing compact two-family development.

6. Multimodal access and vehicular safety shall be enhanced by providing primary access drives that are designed for shared bicycle use, posted for low speed, and designed to include traffic calming measures.

7. A healthy walkable neighborhood shall be encouraged by providing compact development and by constructing sidewalks and other walkways.

8. Water conservation shall be promoted by precluding use of potable water for irrigation and requiring that irrigation of the two-family dwelling units and the multiuse clubhouse must be subject to an irrigation management plan.

9. Sustainable use of materials shall be increased by requiring use of comparable recycled and locally sourced materials for construction of site improvements.

10. Vehicle miles traveled (VMT) and energy use shall be reduced by providing a compact two-family development which limits the required length of the primary access drive system in comparison to the roadway system required for a comparable single-family development.
