On January 10, 2013, you and your wetlands scientist Mary Rimmer presented an as-built plan of the subdivision to the Commission highlighting these deviations. You agreed that additional replication is needed to bring the project into compliance. Ms. Rimmer suggested that the area between the existing wetlands boundary and the boulder wall on 25 Clark Avenue would be an appropriate location for replication. The Commission has received Mary Rimmer's replication plan, dated January 15, 2013, and the right-of-entry agreement executed by the owner of 25 Clark Avenue allowing said replication, as required by the Commission's January 15, 2013 updated enforcement directive. In order to bring the project into compliance with the order of conditions, the Commission requires the following actions: 1. Complete replication by June 30, 2013 in accordance with Ms. Rimmer's January 15, 2013 plan. 2. Obtain verification from the Conservation Agent by July 10, 2013 that the replication was completed per plan. 3. Submit two annual monitoring reports to the Conservation Commission confirming that the wetlands plantings are successful, no later than June 30 of 2014 and 2015. Failure to comply with the Massachusetts Wetlands Protection Act; M.G.L.c.131§40, its regulations at 310 CMR 10.00, Salem's Wetlands Protection & Conservation Ordinance, c.50, and the Order of Conditions issued for work on this site may result in further enforcement action including, but not limited to, fines up to $200 per violation per day.

As you recall,a partial Certificate of Compliance for this site was issued by the Conservation Commission in December,2012 for work associated with 24 Clark Avenue,Assessor Map 6 and Lot 6. The remaining project site was subject to an Enforcement Directive dated November 20,2012 and later revised on January 15 and February 22,2013. This enforcement action required completion of a 1,244 square foot wetland replication at 25 Clark Avenue in order to correct previous discrepancies in wetland impacts associated with the work between the approved plans and As-Built plans. This work was completed, in compliance with the Enforcement Directives and Rimmer Environmental Consulting's mitigation plan described in a January 15, 2013 correspondence to Kenneth Steadman and provided to the Conservation Commission (see attachment). A site inspection was conducted by Conservation Agent Tom Devine on July 31, 2013. At that time, it was noted that the wetland replication area had been correctly constructed and planted but that three red maple trees were missing. The additional three trees were installed and a second site inspection was conducted on October 22, 2013 at which time it was confirmed that the wetland had become successfully established with 100%vegetative cover and that the plantings were thriving(see attached photos). The applicant now requests a full certificate of compliance for the remaining portions of this project. As-Built Plans prepared by Reid Land Survey were previously submitted for the Partial Certificate of Compliance. z If you have any questions or require additional information, please do not hesitate to contact me.

Based upon As-Built survey plans of the project area prepared by Reid Land Survey it was determined that the rock wall constructed at the rear of some of the lots within the original Notice of Intent filing(DEP#64-259)was not constructed exactly according to the approved plans, resulting in wetland filling in excess of the amount authorized in the Order of Conditions and subsequent plan modifications. The majority of this filling appears to have occurred within the lot at 25 Clark Ave Extension. REC and Reid Land Surveyors identified an area of approximately 1,244 square feet on the southwestern side of the rock wall that no longer contains wetland vegetation which could be used to create additional wetland area as mitigation for unpermitted 511. Work required to complete this wetland mitigation is best postponed to spring, but is recommended to be completed no later than June 30,2013. The following is a recommended sequence for construction of this mitigation area: 1. Install an erosion control barrier consisting of either straw wattles or siltation fencing between the currently delineated wetland boundary and the mitigation area at 25 Clark Ave. 2. Cut and remove existing vegetation within the mitigation area. 2 3. Excavate the mitigation area to a grade that is one foot below the elevation of the adjacent undisturbed wetland boundary. 4. Backfill replication area with 12 inches of a clean,good quality topsoil with a minimum 20%organic matter content. The finished grade should match the grade of the existing undisturbed wetland. If topsoil is required to be supplemented to achieve the 20% organic matter content, leaf compost is the preferred soil amendment. 5. Plant according to the following planting plan: 16 Red maple(Acer rubum) min 5 foot height 12 highbush blueberry (Vaccinum corymbosum) min 3-foot height 12 silky dogwood(Cornum amomum) min 3-foot height Plantings should be lightly mulched with salt marsh hay. The remaining exposed soil should be seeded with 0.5 pounds of wetland seed mix such as New England Wetmix available from New England Wetland Plants, Inc. 6. Water plants regularly until fully established. 7. Remove erosion control barrier: In addition, according to the Enforcement Directive, two years of monitoring of the completed mitigation area will be conducted in order to confirm that the plantings are successful.- Site monitoring by a qualified wetland scientist or landscaper will be made to confirm that plantings are viable and replacement plantings will be made during the monitoring period should any plantings fail. Upon successful completion of the above items,we recommend that you notify the Salem Conservation Commission to determine if the terms of the Enforcement Directive have been successfully met. If you have any questions or require additional information,please do not hesitate to contact me.

The Commission permitted approximately 2,020 square feet of wetlands alteration under the condition that the wetlands be replicated at a better than 1:1 ratio. A surveyed plan recently submitted with a request for certificate of compliance by the owner of 24 Clark Avenue shows that %c edands were filled but not replicated as required on that lot. Furthermore, wetlands were Filled as permitted in order to extend the roadway, but the Commission has been unable to confirm whether any of the required replication was completed. At its November 15, 2012 meeting, the Conservation Commission voted to issue this Enforcement Directive requiring the following actions to bring the project into compliance: 1. No later than December 2, 2012, submit evidence that you have retained a surveyor and wetlands scientist to complete the survey and delineation work specified below. Letters from these professionals attesting that you have retained them for this work or contracts for this work will satisfy this requirement. 2.

Unfortunately I no longer have any written records of this work,but can recall supervising the construction of the replication area and specifically remember expanding the replication area somewhat from the plans to allow for removal of additional debris that was located within the areas next to the stream. I also recall returning to the site to conduct follow-up treatments of Japanese knotweed that began to grow along the edges of the replication area later in the year. Lastly,I can recall having some conversations with the Conservation Agent at the time regarding this project and that the isolated wetland that was indicated within the roadway on one of the plans was not jurisdictional under state wetlands protection act or local wetland ordinance at the time. I am sorry not to be able to provide more documentation of this work,but would be happy to discuss it with you if you have.any questions. Very truly, C Mary Rimmer,M.A., P.W.S.

The additional fill does extend into the abutting property at 25 Clark Avenue. The additional fill is approximately 350sf in size and appears to have been completed when the site was originally developed. The lot contains 15,000sf and the developed portion of the lot contains only 7000sf. Due to the fact that the filling was completed by the original developer, it is small in area and to remove it would be extremely difficult and detrimental to the wetland area, I believe it is appropriate to request that your Commission issue the Certificate of Compliance at this time.

ORIFICE FLOW CAPACITY OF NEENAH GRATES FOR PONDING CONDITIONS t For flow through a grate under ponding conditions, orifice type flow occurs. If the net open area is used as the orifice area, the discharge can be computed using the orifice equation Q = CA 2gh where C has a value of 0.60, A = area in square feet, g = the constant value 32.2, and h = depth in feet of water over the grate. The orifice equation is most accurate when large depths of ponding are encountered. At shallower depths, the equation loses its accuracy. The determining factor is the grate's free open area. The ofifice equation remains accurate for grates of smaller area when depths are in the 0.4 - .j 0.3 foot range. Grates of larger free open area are not able to sustain ponding conditions at shallow depths, and therefore flow reverts to weir or one directional flow. Since this equation contains three variables, two must be known to make a determination of the third. To facilitate rapid solution of the equation a nomograph (see page 45) is used. Please note the nomograph is limited to depths of .3 foot. To use the nomograph, a lineIs drawn through the two known values on their respective axis. The third value will be obtained at the intersection of this line with the third axis. For example, if the area of a grate required to pass 6.7 cubic feet/second under a .5 feet head is desired, a line is projected from the .5 unit point on the right axis through the 6.7 unit point on the center axis. This line intersects the left axis at approximately 2.0 units indicating that a grate with a net open area of 2.0 square feet is required. Selection of this grate can be made by referring to the size table for the various Neenah grates. It should be left to the designed to make any necessary reductions in the discharge due to trash accumulation or clogging.

APPENDICES APPENDIX A: Pre-Development Condition Results with Plan No. 1 APPENDIX B: Post-Development Condition Results with Plan No. 2 APPENDIX C: Drainage Facility Design Calculations i Proposed Residential Subdivision in Salem, Massachusetts Project Summary The project proponent proposes to develop a 2.76 acre parcel of land to construct a residential uudivision in Salem, Massac!wsetts The proposed s+!hdivision will consist of the construction of six (6) single family homes that will be accessed by extending the existing bituminous roadway within the Clark Avenue right-of-way approximately 500 feet. Refer to the attached USGS Map Figure I for the location of the parcel and overall drainage plan. This report contains calculations of stormwater runoff for pre and post-development conditions and includes the sizing of the proposed drainage system and subsurface infiltration facility. The majority of the site is presently lightly wooded with topography consisting of steep terrain with slopes ranging from approximately 10 to 35 percent. The majority of the parcel slopes from northeast to southwest towards a stream that traverses the property along it's southern boundary. This stream flows in a southeasterly direction to a large wetland area located near the . Salem/Swampscott Line. Soils information was obtained from the SCS Maps and available data. The soils on the site are classified as Chatfield-Hollis Rock Complex (CrD, SCS Hydrologic Soil Groups B,C and D) and Whitman extremely stony loam(Wh, SCS Hydrologic Soil Group D). Refer to Figure 2, SCS Soils Map, for a delineation of the boundaries of the soil with respect to the subject parcel and the attached SCS soil description information. Pre-Development Condition In both the pre-development and post-development stormwater analysis the watershed area analyzed was the 4.96 acre area consisting of the portion of the parcel and existing right-of-way that will be developed and offsite tributary areas northeast of the site. Refer to Plan No. 1 in Appendix A for existing topography and the delineation of drainage subareas for the Pre-Development Condition. In the pre-development condition, drainage flows in a southeasterly direction towards onsite wetland areas located in the southern portion of the site. The SCS Technical Release 55 (TR-55) Urban Hydrology for Small Watersheds program developed by the Soil Conservation Service(SCS) was employed to develop pre and post-development peak flows. l hi W. a ,amu � d '"`v� ���.� �i .,�-,-, ^�-`']�.,,r. � A „ -:;'� a.� x.�s'- ��t r/I�IiI���T." • net. e.

Refer to Appendix A for computer results, soil characteristics, cover descriptions and times of concentrations for all subareas.

(Flows in cfs) Subarea Al 4 6 9 11 13 Post-Development Condition I� In the post-development condition approximately 500 feet of bituminous roadway have been proposed and all lots have been assumed to have single family home construction with a garage and driveway. Refer to Plan No. 2 in Appendix B for proposed site grading and the delineation of • post-development drainage subareas. Drainage calculations were performed by the SCS TR-55 Method for 5,10,25,50 and 100 year Type III storm events. All drainage structures were designed employing the Rational Method to accomodate peak flows generated by a 100-year storm event. The peak rates of runoff for this condition are as follows.- Post-Development ollows:Post-Development Condition Storm Event Drainage Subarea 5 Yr. 10 Yr. 25 Yr. 50 Yr. 100 Yr.

Condition • r ra In order to ensure that peak flows for the post-develwment condition are less than the pre-development condition for all storm events, the subsurtace infiltration system will be designed to leached or detain approximately 1.5 cfs of the total flows from Subarea A3 that will be directed to the proposed drainage system. An additional 0.50 cis will be leached through a proposed stone swale\infiltration trench located within a proposed drainage casement on Lot 1. Proln) ed DrainageA. _racilitics The proposed drainage system will consist of catch basins located at Stations 3+38 on both sides of the roadway to collect surface runoff. Drainage flows from Subarea A3 will be accepted by the catch basins and directed to the proposed subsurface infiltration system by 12" P.E. perforated polethylene (P.C.) pipes. The leaching facility will be approximately 2,500 s.f. (72' x 35') with at least two feet of clean stone (1 1/2" to 2" in diameter) from the top of the 12" perforated pipe to two feet below the pipe. Geotextile fabric will be placed at all interfaces of stone and soil to ,t prevent the migration of silt and the clogging of the stone layer. Sediments will settle out in catch basin sumps (2 1/2 feet in depth) with hooded pipe outlets to prevent silt from entering the subsurface infiltration system area. The catch basins will be linked with a 12" RCP pipe to offset the asymetry of the watershed area and to use the distibution pipes more efficiently. The proposed subsurface infiltration system is designed, through a combination of infiltration and detention, to attenuate the net increase in peak flows for all storm events estimated as a result of developing the site. The remaining flows from Subarea A3 uncapable of being leached will be " conveved through overflow 12RCP n;nes to , closed+ drainage s, ste;r and + cdwveyed to onsite wetland areas. Erosion and Siltation Control Erosion control measures in the form of hay bales will be placed around the perimeter of all disturbed roadway areas near Locust Street, catch basins inlets and the drainage outlet on Lot#5 prior to the commencement of any construction activity to prevent erosion and the migration of IM soils to offsite areas. The integrity of the hay bales will be maintained by periodic inspection and replacement as necessary. The hay bales will remain in place until the first course of pavement has been placed and all side slopes have been loamed and seeded and vegetation has been established. Construction of the infiltration beds should be delayed until the entire site is stabilized. This will yoevent clogging of the facility from high sediment loads during construction. Atter the bed is nstructed, surface inlets to the trench should be protected from sediment until the site is stabilized and vegetative filtering practices are fully established. s 20 Soil survey • soils.

I ORIFICE FLOW CAPACITY OF NEENAH GRATES FOR PONDING CONDITIONS i For flow through a grate under ponding conditions, orifice type flow occurs. If the net open area is used as the orifice area, the discharge can be computed using the orifice equation Q = CA 2gh where C has a value of 0.60, A = area in square feet, g = the constant value 32.2, and h i = depth in feet of water over the grate. The orifice equation is most accurate when large depths of ponding are encountered. At shallower depths, the equation loses its accuracy. The determining factor is the grate's free open area. The ofifice equation remains accurate for grates of smaller area when depths are in the 0.4 - 0.3 foot range. Grates of larger free open area are not able to sustain ponding conditions at shallow depths, and therefore flow reverts to weir or one directional flow. Since this equation contains three variables, two must be known to make a determination of `) the third. To facilitate rapid solution of the equation a nomograph (see page 45) is used. Please note the nomograph is limited to depths of .3 foot. '1'0 use the nomograph, a line.'is diawn 'through the tvvrc known values on their respective axis. . . . The third value will be obtained at the intersection of this line with the third axis. For example, if the area of a grate required to pass 6.7 cubic feet/second under a .5 feet head is desired, a line is projected from the .5 unit point on the right axis through the 6.7 unit point on the center axis. This line intersects the left axis at approximately 2.0 units indicating that a grate with a net open area of 2.0 square feet is required. Selection of this grate can be made by referring to the size table for the various Neenah grates. I It should be left to the designed to make any necessary reductions in the discharge due to trash accumulation or clogging. For an example of the relationship between the weir and orifice equations and the expected flow through a grate under varying conditions see page 52. I i- 1 AREA OF GRATE —SQ. FT.

The work involves the construction of six (6) single family homes, 5 of which are located within the buffer zone to bordering vegetated wetland. The lots will be accessed by extension of existing Clark Avenue by approximately 500 linear feet. Approximately 1,390 square feet of bordering vegetated wetlands alteration is proposed as a limited project crossing [3 10 CMR 10.53(3)(e)]. An additional 630 is proposed to be altered on Lot 4. Wetland replication is proposed at ratio slightly higher than 1:1 in accordance with the performance standards established in 310 CMR 10.55(4)(b). A stormwater management design is proposed (see attachment 5.0)which will provide for the renovation of roadway runoff and attenuation of peak flows during the 5, 10, 25, 50 and 100 year storm events. Properly installed and maintained erosion and sedimentation controls will provide protection of adjacent wetland resources during construction. Methods Wetland resource areas were delineated at the site on April 18, 1996 and May 14, 1996 in • accordance with the procedures established in the Massachusetts Wetlands Protection Act Regulations (3 10 CMR 10.00) most recently revised on June 30, 1995. The boundaries of wetland resource areas were delineated with a numbered sequence of flags (Al-A24 and Bl-B1]) as shown on the site plans. Both vegetation and soils were utilized in determining the wetland boundary. Documentation supporting the wetland delineation is provided in Attachment 5.0, DEP Bordering Vegetated Wetland Delineation Field Data Forms. Wetland Description The main wetland system, as delineated by the A-series wetland flags, is located along the southern boundary:of the site. It consists of a wooded swamp system bordering a stream with widths up to 20 feet and 6-8 inches of flowing water at the time of observation. This stream flows southeast off the property toward Thompsons Meadow. The vegetative community adjacent to the stream consists of species typical of a New England wooded swamp, including red maple(Acer rubrum), green ash (F'roxiuus pennylvanica), sweet pepperbush (Clethra alnifolia) and pussy willow(Salix discolor). The adjacent uplands consist of black oak (Quercus velutina), grey birch(Betula populifolia), staghorn sumac (Rhus typhina), black cherry(Prunus serotina) and black raspberry (Rubin occidentalis). Much of the northern boundary of this wetland system (Al-A-17) occurs along the toe of an existing fill slope. Vegetation alone was determined to be sufficient to delineate the wetland boundary in most of this area. • A second smaller wetland, tributary to the larger wetland described above, occurs at the base of a fill slope within what is proposed to be the access road. This wetland accepts • surface runoff from Lot 1 and the slope immediately to its west. Upon investigation, it appears the wetland is likely to be very young, since it is underlain with a silty clay loam not found in other areas of the site, and which has most likely washed out of the fill material to the west. According to the property owner, the fill material consists of dredge spoils and contains high amounts of marine clay. This low permeability soil has formed a liner which encourages ponding conditions, which in turn favor wetland plants. The ponded area eventually overtops and a narrow, intermittent channel discharges into the wetland system to the south. The vegetative community indicates a wetland transitional between a wet meadow and shrub swamp, and includes woody species such as pussy willow, speckled alder(Alms rugosa) northern arrow-wood (Viburm4m recognitum) and glossy buckthorn (Rhamnus frangula), as well as herbs such as swamp dewberry (Rubis hispidus), rough-stem goldenrod (Solidago rugosa) and various grasses rushes. Although this area meets the definition of wetlands under the Regulations, due to the nature of its creation and its very small size, its wetland functions are greatly limited. Mitigation Measures The area of wetland alteration has been minimized as much as possible, given the project goals. The majority of the wetland alteration for this project is being proposed as a limited project under 310 CMR 10,53(3)(e), limited access roadways which provides for: The construction and maintenance of a new roadway or driveway of minimum • legal and practical width acceptable to the planning board, where reasonable alternative means of access from a public way to an upland area of the same owner is unavailable. Such roadway or driveway shall be constructed in a manner which does not restrict the flow of water. Approximately 1,390 square feet of wetland is proposed to be altered for roadway construction. This wetland will be replicated immediately south of the crossing and will provide a more complete connection to the existing wetland to the south. A 15-inch concrete culvert will maintain flows under the roadway. An additional 810 square feet is proposed to be altered on Lots 3 and 4 to insure adequate access around the dwellings. In order to minimize impacts during construction due to exposed soils, several erosion control measures are proposed, including sequencing construction activities so as to minimize exposed soil areas, use of haybale barriers around the upgradient side of wetland areas and catch basin inlet protection. Erosion and sedimentation controls will be placed around the perimeter of the work area, as shown on the site plans as well as around catch basin inlets and drainage outlets prior to the commencement of any construction activity. These controls shall be periodically inspected and replaced as needed during construction, and shall remain in place until all exposed soils have been permanently stabilized.An emergency supply of haybales will be kept on-site for erosion control maintenance. • I When loaming and seeding cannot occur within two weeks of final grading, hay mulch or • temporary erosion control seeding is proposed. The stormwater management system has been designed to attenuate peak flows in for the 51 10, 25, 50 and 100-year storm events as described in Section 6.0. In addition, stormwater runoff will be renovated by contact with a subsurface leaching facility located within the roadway. Construction of the wetland replication areas shall proceed in accordance with the following wetland replication plan. Wetland Replication Plan The following procedures are proposed to ensure compliance with the Massachusetts Wetlands Protection Regulations during construction of the wetland replication areas. 1. Properly install al] sedimentation and erosion control devices as shown on the attached site plans. 2. All vegetation within the replication area to be saved or salvaged shall be tagged in place, or balled and burlapped and placed temporarily outside of the replication area. • 3. All wetland vegetation within the impact suitable for use in the replication area shall be similarly set aside for transplanting in a shaded location. t 4. The replication area shall be cleared and grubbed. 5. The replication area shall be excavated to 12-inches below desired finished grade. 6. Since the soils in the impact area are not appropriate for the constructed wetland, topsoil will be imported from off-site. The topsoil shall be mixed with a peat as needed to create suitable wetland soil. This soil will be placed in the replication areas to and rough graded to achieve desired elevations. The soils should be hand raked to roughen. Equipment travel on wetland soils shall be minimized to prevent soil compaction. 7. The replication area will then be planted according to the following planting plan. The selected species are all native to the northeast and consistent with species already present at the site. Transplants from the impact area may be used, in addition to nursery stock, to acheive the desired density and cover.

The seed mix shall contain approximately the following group of species: Sedges Carex spp. 55% (C. lurida, C. crinita, C. stricta, etc.) Fowl Meadow Grass Glyceria canadensis 25% Joe-Pye Weed Eupatoriadelphus maculatus 10% • Woolgrass Scirpus cypermus 05% Boneset Eupatorium perfoliatum 05% Blue Vervain Verbena hastata <5% Actual composition of the mix may vary, depending on availability. These seeds have varying degrees of tolerance to drought and flooding conditions, establishing themselves based upon microtopography and variations in soil moisture. This ensures that many species from the mix will grow in a given site. All seeds are native to the northeast. 8. Depending on the time of year construction occurs, replication areas may need to be irrigated. If construction occurs between May 15 and September 1, weekly irrigation may be necessary. 9. The replication are will be monitored for a period of two full growing seasons to insure full compliance with the requirement for establishment of 75% wetland plant species. • ATTACHMENT 5.0 FIELD DELINEATION DATA FORMS r a • DEP Bordering Vegetated Wetland (310 CMR 10.55) Delineation Data Form Applicant Kenneth G.

The proposed subdivision will consist of the construction of six(6) single family homes that will be accessed by extending the existing bituminous roadway within the Clark Avenue right-of-way approximately 500 feet. Refer to the attached USGS Map Figure 1 for the location of the parcel and overall drainage plan. This report contains calculations of stormwater runoff for pre and post-development conditions and includes the sizing of the proposed drainage system and subsurface infiltration facility. The majority of the site is presently lightly wooded with topography consisting of steep terrain with slopes ranging from approximately 10 to 35 percent. The majority of the parcel slopes from northeast to southwest towards a stream that traverses the property along it's southern boundary. This stream flows in a southeasterly direction to a large wetland area located near the • Salem/Swampscott Line. Soils information was obtained from the SCS Maps and available data. The soils on the site are classified as Chatfield-Hollis Rock Complex (CrD, SCS Hydrologic Soil Groups B,C and D) and Whitman extremely stony loam(Wh, SCS Hydrologic Soil Group D). Refer to Figure 2, SCS Soils Map, for a delineation of the boundaries of the soil with respect to the subject parcel and the attached SCS soil description information. Pre-Development Condition In both the pre-development and post-development stormwater analysis the watershed area analyzed was the 4.96 acre area consisting of the portion of the parcel and existing right-of-way that will be developed and offsite tributary areas northeast of the site. Refer to Plan No. 1 in Appendix A for existing topography and the delineation of drainage subareas for the Pre-Development Condition. In the pre-development condition, drainage flows in a southeasterly direction towards onsite wetland areas located in the southern portion of the site. The SCS Technical Release 55 (TR-55) Urban Hydrology for Small Watersheds program developed by the Soil Conservation Service(SCS) was employed to develop pre and post-development peak flows. , kJ . . .

(Flows in cfs) Subarea Al 4 6 9 11 13 Post-Development Condition In the post-development condition approximately 500 feet of bituminous roadway have been proposed and all lots have been assumed to have single family home construction with a garage and driveway. Refer to Plan No. 2 in Appendix B for proposed site grading and the delineation of post-development drainage subareas. • Drainage calculations were performed by the SCS TR-55 Method for 5,10,25,50 and 100 year Type III storm events. All drainage structures were designed employing the Rational Method to accomodate peak flows generated by a 100-year storm event. The peak rates of runoff for this condition are as follows: Post-Development Condition Storm Event Drainage Subarea 5 Yr. 10 Yr. 25 Yr. 50 Yr. 100 Yr.

Condition In order to ensure that peak flows for the post-development condition are less than the pre-development condition for all storm events, the subsurface infiltration system will be designed to leached or detain approximately 1.5 cfs of the total flows from Subarea A3 that will be directed to the proposed drainage system. An additional 0.50 cis will be leached through a proposed stone swale\infiltration trench located within a proposed drainage easement on Lot I. Proposed Draivaac Facilities The proposed drainage system will consist of catch basins located a of the roadway to collect surface runoff. Drainage flows from Subarea A3 t,w Il be acceptes 3+38 on bothd by sides the catch basins and directed to the proposed subsurface infiltration system by 12" P.E. perforated polethylene (P.E.) pipes. The leaching facility will be approximately 2,500 s.f. (72' x 35') with at least two feet of clean stone (1 1/2" to 2" in diameter) from the top of the 12" perforated pipe to two feet below the pipe. Geotextile fabric will be placed at all interfaces of stone and soil to prevent the migration of silt and the clogging of the stone layer. Sediments will settle out in catch basin sumps (2 1/2 feet in depth) with hooded pipe outlets to prevent silt from entering the subsurface infiltration system area. The catch basins will be linked with a 12" RCP pipe to offset the asymetry of the watershed area and to use the distibution pipes more efficiently. The proposed subsurface infiltration system is designed, through a combination of infiltration and detention, to attenuate the net increase in peak flows for all storm events estimated as a result of developing the site. The remaining flows from Subarea A3 uncapable of being leached will be conveyed through overflow 12" RCP nines to a closed drainage system andx4i=.eyed to onsite wetland areas. Erosion and Siltation Controf Erosion control measures in the form of hay bales will be placed around the perimeter of all disturbed roadway areas near Locust Street, catch basins inlets and the drainage outlet on Lot#5 prior to the commencement of any construction activity to prevent erosion and the migration of soils to offsite areas. The integrity of the hay bales will be maintained by periodic inspection and replacement as necessary. The hay bales will remain in place until the first course of pavement has been placed and all side slopes have been loamed and seeded and vegetation has been established. Construction of the infiltration beds should be delayed until the entire site is stabilized. This will event clogging of the facility from high sediment loads during construction. Afler the bed is I' I nstructed, surface inlets to the trench should be protected from sediment until the site is stabilized and vegetative filtering practices are fully established.
