The purposes of the Flood Hazard Overlay District (FHOD) are to:
1. 
Ensure public safety through reducing the threats to life and personal injury;
2. 
Eliminate new hazards to emergency response officials;
3. 
Prevent the occurrence of public emergencies resulting from degraded water quality, contamination, and pollution due to flooding;

5. 
Eliminate costs associated with the response and cleanup of flooding conditions; and
6. 
Reduce damage to public and private property resulting from flooding waters.
The boundaries of the FHOD shall enclose all special flood hazard areas designated Zone A or Zone AE on the Essex County Flood Insurance Rate Map (FIRM) issued by the Federal Emergency Management Agency (FEMA) for the administration of the National Flood Insurance Program. The map panels of the Essex County FIRM that are wholly or partially within the Town of Andover are panel numbers 25009C0195F, 25009C0203F, 25009C0204F, 25009C0208F, 25009C0211F, 25009C0212F, 25009C0213F, 25009C0214F, 25009C0216F, 25009C0217F, 25009C0218F, 25009C0219F, 25009C0236F, 25009C0238F, 25009C0239F, 25009C0352F, 25009C0356F, 25009C0357F, 25009C0376F and 25009C0377F, dated July 3, 2012. The exact boundaries of the FHOD may be defined by the 100-year base flood elevations shown on the FIRM and further defined by the Essex County Flood Insurance Study (FIS) report dated July 3, 2012. The FIRM and FIS reports are incorporated herein by reference and are on file with the Planning Board and the Building Commissioner.
The FHOD is hereby established as an overlay district. Where the regulations of the FHOD impose greater or lesser restrictions or requirements than those of other applicable bylaws or regulations, the more restrictive shall apply.
Any development within the FHOD, including structural and non-structural activities, whether permitted by right or by special permit, shall be subject to all otherwise applicable requirements of the underlying zoning district in which it is located, including use and dimensional requirements, and also to the following requirements:
1. 
The flood-carrying capacity of any watercourse shall be maintained in the event of any alteration or relocation, as determined by the Building Commissioner upon the advice of the Conservation Commission.
2. 
Within Zone A, the best available federal, state, local, or other floodway data shall be used to prohibit encroachments in floodways that would result in any increase in flood levels within the community during the occurrence of the base flood discharge. Within Zone AE, along watercourses that have not had a regulatory floodway designated, no new construction, substantial improvement, or other development shall be permitted unless it is demonstrated that the cumulative effect of the proposed development, when combined with all other existing and anticipated development, will not increase the water surface elevation of the base flood. Within Zone AE, along watercourses that have regulatory floodways designated with the Town of Andover on the Essex County FIRM, encroachments are prohibited in the regulatory floodway which would result in any increase in flood levels within the community during the occurrence of the base flood discharge.
3.

The Groundwater Protection Overlay District (GWPOD) is established for the following purposes:
1. 
To preserve and protect the groundwater resources in the Zone II of the Tewksbury Hospital water supply wells for the health, safety and general welfare of the residents, staff and visitors to the facility;
2. 
To preserve and protect potential sources of drinking water supplies from detrimental use and development of land, and to prevent temporary and permanent contamination of the environment in the Town of Andover;
3. 
This GWPOD does not limit the existing authority of the Conservation Commission pursuant to G.L. c. 131, § 40.
This GWPOD includes all the lands that create the recharge area for the Tewksbury Hospital water supply wells. This district includes all the areas within the Town of Andover that are designated on the map titled "Andover Parcels, Andover Water Protection Overlay District, and Tewksbury Hospital Zone II Wellhead Protection Zone" which is hereby made a part of the Zoning Map.
1. 
Burden of Proof. When a property owner seeks Town approval for any work done on a lot that straddles the line on this GWPOD as shown on the District map, the owner must include with his or her application, a map on a scale of one inch equals 40 feet prepared by a registered professional surveyor and approved in writing by the Town Engineer, showing the boundary on the owner's lot. The Planning Board may, upon application of the owner of any lot, determine what portion, if any, of such lot is in the GWPOD. Alternatively, the owner may use the Massachusetts Geographical Information System Zone II map information and corresponding lot boundary information to assess the relative location of the owner's lot and the boundary of the GWPOD, subject to approval by the Planning Board. At the request of the owner, the Town may engage a professional engineer, hydrologist, geologist, or soil scientist to determine more accurately the boundaries of the district with respect to individual parcels of land and may charge the owner for the cost of the investigation.
The GWPOD is an overlay district and shall be superimposed on the other districts established by this Bylaw. Land in the GWPOD may be used for any purpose otherwise permitted in the underlying district, subject to the additional restrictions of this Section 8.4. In locations where this GWPOD overlaps the land area delineated by the Fish Brook/Haggetts Pond WPOD (Section 8.8), the restrictions of both areas must be followed.
The following uses are permitted within the Groundwater Protection Overlay District, subject to the design standards set forth in Section 8.4.7:
1.

c. 
To the extent legally permissible, the affordable units shall be offered to give the maximum preference allowed by law to older adult residents of the Town of Andover, employees of the Town of Andover, Andover natives, and relatives of current Andover residents ("Local Preference"). This condition is intended to complement and not to override or supersede the fair marketing regulations of the Department of Housing and Community Development (DHCD), the Massachusetts Commission Against Discrimination (MCAD), or any authority with jurisdiction and like purpose, to provide low- and moderate-income housing.
d. 
The affordable units may be rented, sold, or otherwise provided to qualified older adults in accordance with income and asset limitations established by the authorizing state or federal agency in those instances where the affordable units benefit directly from this assistance, or in the absence thereof pursuant to the definitions of income and assets established for the Low-Income Housing Tax Credit program, or pursuant to the standards promulgated by the Planning Board.

g. 
Although eligibility for the affordable units shall be determined by reference to income and assets of the prospective residents, the affordable units shall be considered affordable only if they are restricted in the amount of monthly rent or other monthly charges for the unit based upon a percentage of the applicable median income. For purposes of computing the monthly rent or other monthly charges for the unit, there shall be excluded any special charges for extra or specialized services that are not provided to the general population of the project but are unique to the particular needs of an individual older adult.
h. 
The standards of affordability for proposed projects, including, without limitation, the methods of determining and maintaining eligibility, the percentage of applicable median income used for limiting the monthly amounts charged for the affordable units and any variations in the percentages of median income in the three income levels shall be set and revised from time to time by the Planning Board provided the standards are consistent with appropriate federal and state standards.
i. 
Prior to the issuance of any building permit for any units, affordability restrictions maintaining all affordable units in perpetuity shall be embodied in applicable deed covenants, contractual agreements, and/or other mechanisms to ensure compliance with this section and shall be submitted to the Planning Board and Town Counsel for review and approval. Prior to the issuance of any building permit for any units, a clearance certificate shall be required to be issued by the Planning Division indicating compliance with this subsection. No clearance certificate shall be issued for any units until (a) all documents necessary to ensure compliance with this subsection including, without limitation, the documents referred to in this Section regarding affordability, including an affordability restriction executed by the Commonwealth's Secretary of Housing and Community Development pursuant to G.L. c. 184, Section 32, have been executed and recorded with the Northern Essex Registry of Deeds; and (b) any required cash or other contribution has been made to the Town or its designee.
j. 
Nothing in this subsection shall preclude a developer from setting aside more than the required number of affordable units or from setting aside additional units for higher but limited income groups or from setting aside more units for lower-income groups.
k. 
For purposes of ensuring that the applicant is abiding by their obligations relative to the affordable units pursuant to the special permit, a monitoring agent shall be assigned by the Planning Board. Prior to the issuance of a building permit, a monitoring agreement shall have been submitted to the Planning Board and Town Counsel for review and approval. The applicant and successors and assigns as owners of the project (applicant/owner), shall pay, in perpetuity, any reasonable fees charged by the monitoring agent/agency.
l. 
If an affordable dwelling unit is a rental unit, on each anniversary of the unit, the applicant/owner will obtain and maintain on file a Certification of Tenant Eligibility in a form and for the time period approved by the monitoring agent. These Certifications shall be filed annually with the Planning Division in the Town. The applicant shall verify that the income provided by an applicant in an income certification is accurate. The applicant will maintain complete and accurate records pertaining to the Affordable Units, and during reasonable business hours and upon reasonable notice, will permit the Town to inspect the books and records of the applicant pertaining to the Affordable Units.
