Box 780 i1 P6;0110 Lynnfield,MA 01940 (/ �0 RE: stabilization and habitat plantings L Parlee Street Extension, Salem Dear Sit: The Definitive Subdivision now in revision proposes approximately 5,700 square feet of grading in proximity to Bordering Vegetated Wetlands. (No actual disturbance of wetlands is proposed.) Much of the proposed work consists of embankments to contain the proposed stormwater treatment basins. The exterior slopes of the basin embankments should be periodically cut to prevent the growth of large trees,but such cutting should be done no more frequently than every two years. The consequent development of a dense shrub layer will provide shelter,food and nesting sites for various wildlife species present in the adjacent wetlands and upland buffer. Four(4)inches of loam shall be applied to all finished slopes. An upland restoration seed mix(catalog cut attached)shall be applied at the supplier's recommended rate, and lightly mulched with clean straw. No watering is necessary. The specified seed mix is designed to provide a dense layer of herbaceous plants in the short term,while encouraging development of a low shrub cover over the course of two or three years. All species incorporated in the specified mix are indigenous plants with significant habitat value. If you have any questions, please feel free to contact me.

The existing property currently consists of 1.71 acres of undeveloped residential property, situated along a hillside. The hillside is vegetated with the exception of portions of the existing Parlee Street right-of-way, as well as some ledge outcrops. The existing hillside slope is approximately 7% and shows only minor erosion. Drainage for this existing hillside area flows towards wetlands situated to the southwest of this development. The primary hydrologic soil group in this area consists of Chatfield (Type B). 2. DESCRIPTION OF PROPOSED DRAINAGE FEATURES. The proposed drainage system will direct treated runoff towards a proposed detention pond situated to the southwest of this development, with two 8" metered discharges, outleting into existing wetlands. The proposed detention pond shall service the proposed Parlee Street roadway extension, proposed driveways, as well as one-half of all future proposed roof surfaces. The remainder of roof surfaces shall be routed towards individual stormwater infiltration systems. Before entering the detention pond, stormwater shall be treated via deep sump catch basins with oil/water separators in order to provide pretreatment of potential petroleum laden stormwater runoff. Secondary treatment will be provided by a sediment forebay within the detention pond. Groundwater elevations are assumed to be elevation 98.5, based on elevations of wetland flagging. 3. PEAK STORM DISCHARGE SUMMARY. The purpose of stormwater modeling is to determine how effectively a proposed drainage system will be able to reduce or hold constant the amount of stormwater runoff leaving a developed site. To achieve this goal, the HydroCAD 3.2 Stormwater Modeling System was utilized to determine the runoff rates for the 2, 10 and 100-year Type 11 storm events. The HydroCAD system is based on the U.S.D.A. Soil Conservation Services Technical Release 20, a unit hydrograph procedure. The addition of impervious area potentially generates a greater amount of stormwater runoff. In order to reduce the stormwater runoff produced by the development of the site, additional drainage pipes, structures and a metered discharge detention pond have been incorporated to reroute stormwater runoff, effectively increasing times of concentration, thus spreading out overtime the various peak flows discharging off site. The following table is a summary of the peak flows generated by the 2, 10 and 100-year storm events for both pre and post development flows. 24 hour rainfall frequencies utilized for this report are the result of Cornell University Technical Publication No. RR 93-5 dated 9193. Refer to the pre and post development drainage plans to be included in this report for the location and extent of the subcatchments(SC) listed in the table. Based on the results below, no changes in upstream and downstream flooding are anticipated. Although the table depicts a decrease in rate for pre-development to post-development conditions, we feel the total volume of water supplied to the existing drainage system and wetland resource areas will not be decreased appreciably. We do not anticipate any negative impacts on downstream wetlands and vegetation. The design of the systems in accordance with the DEP Guidelines lead to the rate decrease shown due to the multiple BMP concept and its effect on those rates.

The Depart- ment ofEnvironmental Protection(DEP)recommends that applicants submit this form with the No ace of Intent, as well as supporting documentation andplans, to provide stormwater information for conservation commission review. If a paracu-lar stormwater management standard cannot be met information should be provided to demonstrate how adequate water quality and water quantityprotection will be provided by the project. DEP encourages engineers to use this form to certify that the project meets the stormwater management standards as well as acceptable engineering standards. This form should be completed by checking the appropriate boxes for each standard and by signing and stamping the back of thisform. Project Location: Parlee St., Salem, MA ® The proposed project is/i no.(circle one)exempt from one or more of the stormwater management standards. If project is exempt,explain why: Stormwater runoff volumes to be treated for water quality are based on the following calculations: (check one thatappiies)Does not apply, all impervious post-development runoff retained on-site. ❑ 1 inch of runoff x total impervious area of post-development site for critical areas(e.g.Outstanding Resource Waters and shellfish growing areas) 0.5 inches of runoff x total impervious area of post-development site for other resource areas Standard#1: Untreated stormwater See Sheets 2-7 and drainage cales ® The project is designed so that new stormwater conveyances(outfalWdischarges)do not discharge untreated stormwater into, or cause erosion to,wetlands or waters. Standard #2: Post-development peak discharge rates See Sheets 2-7 and drainage calcs Post-development peak discharge rates do not exceed pre-development rates on the site either at the point of discharge or down adient property boundary. LJ N/A:project site contains waters subject to tidal action, so standard is not applicable. Stormwater controls have been designed for the 2-year and 10-year,24-hour stones. ® The project's stormwater design will not increase flooding impacts offsite from the 100-year,24-hour stone. Standard #3: Recharge to groundwater See Sheets 2-7 & drain. calcs. ® The annual groundwater recharge for the post-construction site approximates annual recharge from existing site conditions. Soil types have been identified according to either the U.S.Natural Resources Conservation Service(NRCS)County Soils Survey or onsite soil evaluation.

PARTY RESPONSIBLE FOR OPERATION AND MAINTENANCE (DURING CONSTRUCTION ONLY) Ledgewood Hills Realty Trust P.O. Box 780 Lynnfield, Ma 01940 (978) 844-7026 4. MAINTENANCE TASKS AND SCHEDULE The following section identifies routine and non-routine maintenance tasks for the proposed stormwater management, along with associated schedules for inspection and maintenance. 4.1 CONSTRUCTION PERIOD All efforts will be made to avoid impacts to nearby wetland areas. During the construction period, the erosion control methods as presented on the site plan will be installed and periodically inspected to check sedimentation, minimize the exposure of areas, and revegetate or stabilize exposed soils as soon as possible. Structural and vegetative methods will be used to minimize erosion and control any sedimentation that may occur. All activities within the plan will adhere to Soil Conservation Service guidelines, as well as the specifications detailed by DEP in the publication Protecting Water Quali in Urban Areas (Minnesota Pollution Control Agency, 1989. Published by: Office of the Massachusetts Secretary of State, Michael Joseph Connolly, Secretary). The following measures will be employed. 4.1.1 General Notes • The construction contractor shall maintain all sedimentation and erosion control structures throughout the project site for the duration of the construction. These devices will be inspected and maintained on a daily basis. • The proposed plan will minimize the exposure of areas during construction in order to minimize the erosion process. In addition, exposed areas will be stabilized and revegetated as soon as possible. No earthmoving activities will take place prior to the establishment of erosion and sedimentation control measures. • Deposited sediment collected by the erosion control measures will be removed periodically, and the condition of the siltation barrier will be maintained until such time that the site has been adequately stabilized with permanent grass cover or pavement. • Areas that will be bare for a period of more than one month, but less than twelve months, will be stabilized by means of appropriate temporary vegetative cover. The cover will be one or a mixture of the following fast- growing grasses: annual ryegrass, sudangrass, millet, winter rye. 0 • Proposed swales and other drainage structures on-site will be inspected regularly and cleaned of accumulated sediment, grit, and other debris as needed in order to maximize effectiveness. 4.1.2 Construction Sequencing and Erosion Control • erosion control barrier will be installed and functioning at the limits of construction. • The proposed earthwork areas will be cleared and grubbed. • All slopes greater than 3:1 shall be seeded and mulched and installed within 72 hours of completion. • All swales and ditches with slopes exceeding 5% shall be stabilized with jute netting. • Pavement subgrade areas shall be constructed, followed by placement of subbase in all areas to be paved. Install utilities. Place pavement base courses and compact. Install fence surrounding detention pond. • All pavement areas to be stabilized immediately after grading. Begin temporary and permanent seeding and mulching. All cut and fill slopes shall be seeded and mulched immediately after construction of these areas. The maximum area allowed to be disturbed and left unstabilized is two acres per drainage area. • Bituminous concrete pavement to be placed. • Temporary diversion channels to be constructed as required. • Daily or as required, construct temporary berms, drainage ditches, silt fences, haybales, etc. Mulch and seed as required. • No permanent planting to be placed prior to 1 May nor after 1 September. • All disturbed areas shall be stabilized with fast-growing grass and mulch, and not left bare for more than 30 days nor over the winter months. • Complete permanent seeding and landscaping. • All swales shall be properly stabilized before directing flow to them. • After site is sufficiently stabilized by vegetation or pavement, remove temporary control measures and accomplish final clean- up. 4.2 POST-CONSTRUCTION AND LONGTERM MAINTENANCE (CITY OF SALEM) 4.2.5 Roof Maintenance (INDIVIDUAL HOME OWNER) The roof will be inspected on a biannual basis in order to maintain it's condition. The roof will be repaired as specified by the manufacturer where chipping, wear, or other defects are observed in the surface. A 4. PRE-DEVELOPMENT DRAINAGE. HANCOCK JOB Survey Associates,Inc.

THE WARREN FIVE PEABODY,MA B'00460911' ►,: 7i638t: 14901978911' #8735 PROJECT NARRATIVE Project Activities The applicant is hereby submitting a Notice of Intent to the Salem Conservation Commission for the proposed construction of a roadway extension, 3 single family homes, stormwater management structures,utilities, and associated grading. The roadway will be an extension of Parlee Street. Work will be conducted within the buffer zone to bordering vegetated wetland. At this time, the development of three single family homes is being proposed. The lots, as shown on the site plan, have been in existence since the 1950's. Stormwater management structures, including a detention pond, roadway drainage infrastructure and roof infiltration trenches have been designed in accordance with the DEP Stormwater Management Policy Guideline. Drainage calculations are included with the Notice of Intent submission. Wetland Resource Areas Bordering Vegetated Wetland A bordering vegetated wetland (BVW) and resource area was identified and flagged on the subject property by Rimmer Environmental Consulting in September 2000. Inland bank associated with an intermittent stream also exists on the subject property. Resource area boundaries were approved under an Order of Resource Area Delineation issued by the Salem Conservation Commission on June 28, 2001. A copy of the Order is attached. Estimated Habitat The subject property is not located within mapped estimated habitat of rare wildlife and certified vernal pools (see Salem Quad map). Measure to Protect Wetland Resource Areas All efforts will be made to avoid impacts to wetland areas adjacent to the proposed project. During the construction period, a sedimentation and erosion control plan will be followed to check sedimentation, minimize the exposure of areas, and revegetate or stabilize exposed soils as soon as possible. Structural and vegetative methods will be used to minimize erosion and control any sedimentation that may occur. All activities within the plan will adhere to Soil Conservation Service guidelines, as well as the specifications detailed by DEP in the publications: Protecting Water Quality in Urban Notice oflntent 1 Parlee Street Salem„A1A Areas (Minnesota Pollution Control Agency, 1989. Published by: Office of the _ Massachusetts Secretary of State, Michael Joseph Connolly, Secretary). Limit of Work In order to protect wetland areas adjacent to the project, boundaries of work zone and wetland areas will be staked and flagged conspicuously. Prior to construction, an erosion control barrier of double-staked haybales and filter fabric will be erected at the limit of work in Buffer Zone between wetland areas and all construction. Earthmoving and Land Grading Activities The proposed plan will minimize the exposure of areas during construction in order to minimize the erosion process. In addition, exposed areas will be stabilized and revegetated as soon as possible. No earthmoving activities will take place prior to the establishment of erosion and sedimentation control measures. All grading work will incorporate practices to minimize erosion of the land. Sharp breaks in the grade of embankments will be avoided. In addition, the top and toe of the slopes of embankments will be rounded to blend with the adjacent land. Sedimentation and Erosion Control Control of erosion and the resulting sedimentation will be achieved through the use of structural and vegetative methods. At the limits of work in the vicinity of wetlands, an erosion control barrier of double-staked haybales and filter fabric will be installed. Deposited sediment collected by the erosion control measures will be removed periodically, and the condition of the haybales will be maintained until such time that the site has been adequately stabilized.

TO: Kevin Cornacchio Chm. Joseph Fumari Asst. Chm. RE: Parlee St. Ext. Responding to recent questions referred to this office please be advised of the following: 1. Streets are swept 16 hours a day five days a week(3pm-7am). We make a serious effort to sweep each neighborhood every two-three weeks barring emergencies. 2. We attempt to clean catch basins annually. Problem areas are done more often. 3. Detention ponds are mowed and cleaned as required, provided they are on City owned land. As a rule they are checked in the spring and fall plus before and after significant storms. 4. This is a very small project and we do not envision any problems with the proposed drainage system. I hope this answers your questions, however please do not hesitate to contact this office if you require additional information.

BOX 780 Boston,MA 02210 Lynnfield, MA 01940 (617)350-7906 RE: stabilization and habitat plantings Parlee Street Extension, Salem Dear Sir: The Definitive Subdivision now in revision proposes approximately 5,700 square feet of grading in proximity to Bordering Vegetated Wetlands. (No actual disturbance of wetlands is proposed.) Much of the proposed work consists of embankments to contain the proposed stormwater treatment basins. The exterior slopes of the basin embankments should be periodically cut to prevent the growth of large trees, but such cutting should be done no more frequently than every two years. The consequent development of a dense shrub layer will provide shelter, food and nesting sites for various wildlife species present in the adjacent wetlands and upland buffer. Four(4) inches of loam shall be applied to all finished slopes. An upland restoration seed mix(catalog cut attached) shall be applied at the supplier's recommended rate, and lightly mulched with clean straw. No watering is necessary. The specified seed mix is designed to provide a dense layer of herbaceous plants in the short term, while encouraging development of a low shrub cover over the course of two or three years. All species incorporated in the specified mix are indigenous plants with significant habitat value. If you have any questions, please feel free to contact me.
