' _ �. �,� _.Lot 2 - Salem Turnpike 242-479 / r� °l , ' /2 r� After reviewing the above-listed information, the NACC finds that the proposed projects, either individually or combined, cannot be adequately conditioned to protect the interests identified under the Wetlands Protection Act and the Town of North Andover Bylaw.. Accordingly, both projects are denied. (Although two Notices of Intent were filed, the development was properly presented as one project due to the close proximity and inter-connected nature of the proposed buildings. This denial is a denial under both Notices of Intent.) As the basis for its denial, the NACC finds the following deficiencies: Concerning Lots I and 2 1. The following; wetland resource areas are affected by the proposed work: bank'', land under water, land subject to flooding (bordering and isolated) , and bordering vegetated wetland. These resource areas are significant to the interests of the Act and Town Bylaw. These resource areas are also significant to the recreation interests of the Bylaw. The applicant has not attempted to overcome the presumption of significance of these resource areas to the identified interests. 2 The wetland resource boundary is still in dispute. The developer has appealed the NACC's positive determination based on the delineation and extent of bordering vegetated wetland and bordering land subject to flooding. Although the NACC's delineation of the bordering vegetated wetland appears to have been used in the Notices of .Intent, the bordering land subject to flooding boundary has not been resolved. The NACC contends that a much greater portion of the site consists of bordering land subject to flooding under the Wetlands Protection Act. The applicant contends that this land is not "bordering" land subject to flooding. If so, most of the site is still clearly a resource area (land subject to "storm flowage, or flooding, or inundation by groundwater or surface water") under the Town of North Andover Wetlands Bylaw and must be so delineated. The NACC finds that use of the wetland resource areas on site for detention of =' storm runoff to be inconsistent with the performance standards for protecting these wetlands. The discharge of storm runoff from the developed portions of the site will directly dump loads of pollutants (e.g. oil, gasoline, salt, nutrients, and bacteria) and sediments to the wetland resource areas with only minimal screening at the catchbasins and swales. Furthermore, the increase in water level caused by increased runoff will affect the hydrologic regime of the wetlands. This alteration of wetland resource areas would put the project outside of the performance standards of the regulations. Accordingly, the projects' drainage systems will be re-designed to control storm runoff through one of the following two alternatives: a. the use of detention or retention ponds constructed outside of the wetland resource areas on the site (both Lots I and 2) , with all the storm drainage directed to these ponds. This alternative would eliminate the need for some of the wetland replacement areas proposed by the applicant. b. the use of sedimentation ponds to receive the storm runoff from all point discharges from the drainage system to act as filters for this runoff, and the use of the wetland resource areas only for the purpose of flood storage Lot 1 - Berry Street 242-478 Lot 2 - Salem Turnpike 242-479 for the extra site runoff. This alternative will require the control structures at the outlets of the wetland resource areas to be identical in their rating curve to the existing natural control structures, and shall result in increased elevations within the wetland resource areas for only infrequent or rare storm events. All runoff from roof drains and parking lots shall be routed through these detention and retention areas. The NACC will require MDC gas and oil traps or their equivalent. r. \f4,. As proposed, the combined total of bordering vegetated wetland to be altered on both sites is approximately 5100 sq.—'are feet. The NACC finds that this figure can be reduced significantly by redesigning the detention ponds as described above, and by eliminating the wetland crossing on Lot 2. yr5r1 extensive work is proposed in the buffer zone; this project has been shoe-horned onto a site extremely limited by the amount of wetland. Accordingly, the NACC will impose a buffer zone in which no work will be permitted; this will ensure that the wetlands are not impacted during construction. `61 As proposed, the wetlands replication plan is unacceptable. The replacement areas, as sited, have the potential for adversely affecting significant areas L. of existing wetland. The amount of wetland replication needed should decrease when the project is redesigned; any replication then necessary should be discussed with the conservation administrator before final plans are drawn. } WILDLIFE HABITAT EVALUATION RIPARIAN INDUSTRIAL PARK - LOT 1 NORTH ANDOVER, MA September 27 , 1988 INTRODUCTION This report is being prepared as accompanying information to a Notice of Intent application for a proposed development, as a result of resource area alterations above the permitted thresholds , defined in the regulations promulgated under the Wetlands Protection Act at 310 CMR 10 . 54 (4) (a) (5) and 10 . 56 (4) (a) (4) . This evaluation is being prepared in compliance with the directions outlined in the aforementioned regulations at 310 CMR 10. 67 , and utilizing the D.E.Q.E. Wetlands Program Policy 88-1. EXISTING CONDITIONS The area of the work within the resource area is on a portion of the property which has been mowed regularly, and consists of an open field with a man--made ponding area, presumably dug to create a farm pond for the animals which grazed in the field at that time. This farm pond, although not large enough in area to be classified as a pond under the regulations, can be described as a large, wide portion of a stream, and as a result, contains the resource area inland bank . The bank area is rather steep-, and is vegetated with purple loosestrife (Lythrum salicaria) , sensitive fern (Onoclea sensibiles) , and upland grasses. The soil structure of the bank areas was very similar to that which existed on the rest of the site . There was approximately 1 to 1.5 feet of a loamy top soil, with a sand layer appearing at approximately 1.5 to 2 feet down. The ground water , at this time, was high, and seemed to coincide with the layer of sand. There was no evidence of any cavities suitable for burrowing, although the soil was such that burrowing could occur , and the topography was such that there are no mud flats or exposed areas within this resource area type. The plant community was very simple, consisting of the three species previously mentioned. They all had approximately 40 - 50% cover , were homogeneously mixed, and there was only one vegetation type ranging from about . 5 to 2 feet in height. There were no dead branches or debris in the area, and there is no opportunity for edge or interspersion to occur . Wildlife Habitat Evaluation Riparian industrial Park Lot 1, North Andover , MA September 27 , 1988 PROPOSED CONDITIONS The project proposes to alter this resource area type in order to construct a proposed detention pond, which will function within the stormwater management scheme for the proposed industrial park . In order to construct the pond, approximately 230 linear feet of bank is proposed to be altered . As indicated on the sample checklist included in the Appendix of this report, the regulations allow for a threshold of 50 linear feet of bank or 10%, whichever is less on the property, before a significant alteration to wildlife habitat is deemed to occur . There is calculated to be well over 500 linear feet on the property, such that the 50--foot threshold is incurred. The proposal of the new detention pond will create a total of 370 feet of bank on this site. The replication of wildlife habitat values in this area will be fairly simple and uncomplicated . By understanding the existing vegetation growing in the area, it is clear that the propagules of these species exist in the soil and, once the slope is stabilized, will revegetate with the same plant community. CONCLUSION The restoration and replication of altered habitats are required to meet specific performance standards outlined at 310 CMR 10. 60 (3) . These standards, and how the project proposes to meet them, are summarized below. "3 (a) : The surface of the replacement area to be created ( "the replacement area") shall be equal to that of the area that will be lost ("the lost area") ; " As shown on the accompanying plan, the lengths of the resource area above the permitted thresholds is proposed to be replaced. "3 (b) : The elevation of groundwater relative to the surface of the replacement area shall be approximately equal to that of the lost area; " The grading shown on the plans submitted with this Notice of Intent proposes such a similar relationship to the groundwater . I i Wildlife Habitat Evaluation Riparian Industrial Park - Lot 1, North Andover , MA September 27 , 1988 "3 (c) : The replacement area shall be located within the same general area as the lost area. In the case of banks and land under water , the replacement area shall be located on the same water body or waterway, if the latter has not been rechanneled or otherwise relocated; " Refer to the accompanying plan. The grading shows a Location on the same water body and in the general vicinity as the lost area. "3 (d) : interspersion and diversity of vegetation, water and other wildlife habitat characteristics of the replacement area, as well as its location relative to neighboring wildlife habitats, shall be similar to that of the lost areas, insofar as necessary to maintain the wildlife habitat functions of the lost area; " The plan proposes such a similar location to resource areas and upland areas , and a vegetational community that is similar or identical to that proposed to be lost. "3 (e) : The project shall not alter 10 or more acres of land subject to flooding or land under water bound to be significant to the protection of wildlife habitat, or 2,000 feet or more of bank found to be significant to the protection of wildlife habitat (in the case of bank of a stream or river , this shall be measured on each side of said stream or river) ; " The project does not propose an alteration of 2, 000 feet or more of bank. 113 (f) : If the replacement area is located in an area subject to the Act, there shall be no adverse affect on the existing important wildlife habitat functions of said area, as measured by standards of this section; " The construction of the detention pond proposes to alter a portion of the bordering vegetated wetland. This area has been addressed in the Notice of Intent application in the section referring to the performance standards required for alterations of bordering vegetated wetlands. f l Wildlife Habitat Evaluation Riparian industrial Park - Lot 1, North Andover, MA September 27 , 1988 "3 (g) : The "thresholds" established in 310 CMR 10. 54 (4) (a) (5) , 10. 55 (4) (a) (4) , and 10 . 57 (4) (a) (3) (below which alterations of resource areas are not deemed to impair capacity to provide important wildlife habitat functions) shall not apply to any replacement area ; and 3 (h) : The replacement area shall be provided in a manner which is consistent with all other general performance standards for each resource area in Part III of these regulations . " The work within this resource area, and the construction of the replacement area, will be constructed in a manner which limits the amount of alteration proposed. Erosion and sediment control guidelines, as outlined in the Erosion and Sedimentation Control Report, will be implemented prior to any construction, and until the area is stabilized and revegetated. k � I APPENDIX RI' 'RIAN INDUSTRIAL PARK -- LOrf i,.�RTH ANDOVER, MASSACHUSETTS L D.E„Q..-E WETLANDS PROGRAM POLICY 88-1 WILDLIFE HABITAT EVALUATION CHECKLIST FOR PROJECTS ON INLAND BANKS* 1 .

REQUIRED MEASUREMENTS OF INLAND BANKS TOPOGRAPHY: Slope & aspect; length, height & area of Bank. SOIL STRUCTURE: Substrate composition (% sand, silt, gravel, organics & clay); depth of soil horizons to 3' or impervious material ; abundance of cavities suitable for burrowing (none, few, many) ; size and number of mud flats and other exposed area. PLANT COMMUNITY COMPOSITION AND STRUCTURE: cover trees, shrubs, herbaceous plants, aquatic plants, leaf litter, & low ground cover; vegetative interspersion; ID of species making up at least 10 of each of the following .vegetative types: trees, shrubs, herbaceous vegetation and aquatic plants; pattern of distribution of such plant species (clumped, random or uniform); range of shrub height (% 0--3' , 3-6' , & above 6' ); depth of leaf litter; number & size (diameter at breast height) of standing trees wi.th cavities, as well as diameter of such cavities (less or more than 3"); % of water along bank overhung by tree and shrub branches and height of such branches (under 3' , 3-6' , above ,6' ) ; number and size of dead vegetation extending into water which is suitable for basking and perching; identification of any migratory area (area used by wildlife moving from one habitat to another, whether seasonally or otherwise) to be altered by the proposed project in a mariner that would have a substantial •adverse effect on wildlife species which may use such area. ADDITIONAL FEATURES OF PROJECT SITE WHERE OFFSITE REPLICATION IS PROPOSED: Wildlife habitat types within 500 feet from the boundaries of the Bank, with particular emphasis on habitats directly adjacent the Bank. The description of the habitat characteristics of the area: directly bordering the Bank should be somewhat detailed (eg, depth and permanence of water next to the Bank, as well the predominant vegetative and soil structure of the land under such water and of the immediate area on the landward side of the Bank). Other, more distant areas can be described according to their dominant vegetative, hydrologic and/or land use type (eg, lake, pond, stream, river, deep marsh, shallow marsh, wet meadow, shrub swamp, wooded swamp, bog, floodplain, agricultural or open land, forest land, mining or waste disposal area, or commercial/ industrial/residential area with average lot size 1/2 acre or less, 1/2 to 2 acres, or 2 acres or more). d. Has the applicant provided site specific plans and calculations which are adequate to ensure that each of the measured- habitat characteristics will following 2 growing seasons of project completion and thereafter (ar if the project will eliminate trees, upon the maturity of replanted saplings) be_ substantially maintained restored or replicated (except for 'those portions of the Bank which fall below the threshold of permissable alterations noted in Question 1 ? X YES NO If "yes"; proceed to Question 5; if "no";•-project should be denied. Except for those portions of the Bank which fall below the threshold of permissable alterations noted under Question 1, the Department will assume that any substantial alteration in the type or amount of any measured habitat characteristic will substantially reduce its capacity to provide important wildlife habitat functions in violation of the regulatory standards, unless the applicant provides clear evidence to the contrary. If the applicant wishes to provide such evidence, see Question 7, below: -5. Does proposed on-site restoration or off-site replication meet all the performance standards specified in 310 CMR 10.60(3)? X YES NO If "yes", the project meets the performance standards of 310 CMR 10.60 regarding-non-rare wildlife species habitat of the Bank -- proceed--to Question 6; if "no", project should be denied. 6. Does the project meet the requirements of 310 CMR 10.59 regarding rare wildlife species habitat -- see "Rare Wetland Wildlife Spec es Habitat Checklist" on p. 21 below? X YES NO 7. Has theppj2licant provided clear evidence that a 12roposed alteration in the type or amount of any measured habitat characteristic will not due to site-specific circumstances substanti JIV reduce its capacity to provide important wildlife habitat functions food shelter mi ratory or overwintering _areas or breeding areas)? (Such evidence should address each of the "important" wildlife habitat functions which may be provided by each habitat characteristic, described in the text on the following two pages.) YES (Mote which habitat charaeteristic(s)) HO If "yes", proposed alterations of the noted habitat characteristic(s) should be permitted and such characteristic(s) should not be subject to the requirements contained in Questions a and 5; all other habitat characteristics are subject to those requirements.
