El @c ?in c. 1.0 Introduction 1.1 BachMund The Seabrook foredunes are one of three discreet sand dune areas remaining on the New Hampshire coast. These dunes are located within an approximate 5,400 ft. reach between State Line Street and Hooksett Street (Locus Map). Due to a meandering tidal inlet at Hampton Harbor to the north and varying sand supplies, these dunes have formed since the early 1900's as part of an accretional barrier spit system. The vertical and horizontal growth of the dunes provides for flood control and storm damage prevention which protects private and public property located further landward. Because these dunes have been badly eroded and degraded, their natural function capacity has been severely limited. Erosion and vegetation loss have been caused primarily by encroachment of adjacent beach users, and by pedestrian movement through these dunes at public access points leading to the beach. 1.2 RMose The purpose of this project is to identify measures to improve and restore the dunes where they have been eroded, damaged or not allowed to grow; to identify the availability, volume, and cost of materials; and, to develop a pedestrian circulation plan which includes specifications for walkway construction through the dunes. All measures, materials, and plans will be used or designed to be used for recreation purposes, as required by zoning. The primary effort is focused on improving the beach access routes extending seaward from 14 public streetends. Improvement and restoration of degraded dunes between these extended street accessways is also part of the project. Dune form, volume, and vegetation are the primary characteristics necessary to protect the natural functional capacity of the foredunes. 1.3 ARRroach A three-phase work plan was implemented to provide the Town with 1) planning and conceptual design, 2) preliminary engineering and environmental assessment and 3) final design. Meetings were conducted with the Conservation Commission and the Town Administrative Assistant. Field measurements and observations, ground photos, and discussions with beachgoers occurred during the summer of 1988. Existing aerial photos and topographic information were combined to provide four base maps at a scale of 1" = 50'. Construction materials, sources, and costs for access routes, dune protection. waste disposal, and signage are documented in the environmental assessment narrative and, to the extent necessary, provided on the project plans. Construction priorities (i.e., high, moderate, and low) are proposed to allow the Town flexibility in completing the project within Its financial ability. 2.0 Existing Conditions 2.1 General DescriRtion The Seabrook foredunes are located seaward of and parallel to U.S. Route 1A (between State Line Street and Haverhill Street) and Atlantic Avenue (between Haverhill Street and Hudson Street). Private ownership seaward of the street-ends off Route 1A and Atlantic Avenue is limited to a zone of single house lots approximately 100' deep. A total of over 60 lots define this zone as developed with residential dwellings, pools, garages, and 2 01 @c ?in c. landscaping features which have modified the dune environment. It is the area between these properties and the beach which is owned by the Town of Seabrook and is in need of improvements. In general, the land between the privately-owned properties that provides an entry to the dunes from the street-ends no longer exhibit the surficial characteristics (e.g., sediment and vegetation) of the natural dune. The predicted 100-year storm elevations for this stretch of dunes is 14'NGVD as mapped by the Federal Emergency Management Agency in August 1985. in general the dunes north of State Line Street become wider, higher, more stable, and less used for beach access. The dunes are generally composed of a single swale and ridge system. Nearby residents have paid for construction and have placed different access structures along the public access ways; however, these are temporary and deterioration of the dunes continues. The dominant vegetative species throughout the foredune swale and ridge system is American beachgrass (Ammophila brevigulata, dom.). Other species observed in the swales include beach heather (Hudsonta tomentosa and seaside golden rod (SolidagQ sempervirens. Beach pea (LathyMr2 marUimus, poison ivy (Rhus radicans. daisy miller (Artemista gtelleriana , and salt-spray rose (Rosa rugosa were observed within the dune ridge. No wildlife was observed in the dune system during four, summer, daytime site visits. Within the northern most 2200 feet of dune from Lawrence to Hooksett Streets, dune toe areas ranging from 30 ft to 65 feet exhibit newly established stands of American beachgrass. The predominant cause of dune destruction is pedestrian traffic accessing the beach. In addition, numerous recreational and aesthetic uses conflict with proper dune management. These include artificial cuts for views of the ocean from dwellings. cleared and flattened pathways and areas for boat storage. volleyball courts, sitting and lying areas protected from the wind and cookout areas. 2.2 Street-end Aeqepjm_@ Public access to the beach in Seabrook is provided in areas extending seaward from some 14 public streets (see Locus Map) listed as follows: 1. New Hampshire 8. Andover 2. Amesbury 9. Dracut 3. Newbury 10. Lowell 4. Groveland 11. Chelmsford 5. Haverhill 12. Tyngsboro 6. Lawrence 13. Nashua 7. Methuen 14. Hudson Hooksett Street, located north of Hudson Street is an additional public access, but was not included in this project. In addition to pedestrian use, vehicular use is allowed by deed only at Haverhill Street. New Hampshire Street is currently used by town-owned vehicles for beach trash pick-up in lieu of State Line Street. Evidence of small off-road vehicles was also observed at several other streetends. Specific measurements (i.e., proffles) of the eidsting topography along the street-end accessways were taken in June 1988. Distances and elevational changes were recorded starting at the street-ends and finishing at the low-tide water line (Table 1). Four distinct 3 MI @C ?C. zones along each profile were determined (i.e., entry, dune swale, dune ridge, and beach) in order to differentiate between potential walkway treatments. The dune swale and ridge system ranges between 200 ft. from street-ends to the beach and 525 ft. in width at Newbury and Nashua Streets, respectively. Tbe crests of these dunes range between 4.1 ft. and 8.3 ft. above the street elevations with extremes of 1.5 ft. and 10.8 ft. at Haverhill and Andover Streets, respectively (Table 2). The distances from the dune crest to the summer berm varied from 150 ft. to 275 ft. Each profile is graphically represented in Appendix A to show the variation in topography from the entry to the beach. Superimposed on the profile in a lighter-weight line is the adjacent grade to demonstrate how much of a cut presently exists in the dune. This information was used to calculate the amount of fill necessary to improve the integrity (e.g., form and volume) of the dune. 3.0 Proposed Project &I Geneml DescriRtIon Improvements to the Seabrook dunes are necessary to address a number of related concerns including access and dune protection. These include the introduction of sand to be used as fill material, salt-tolerant vegetation, walkway structures, fencing, signage, and the potential of ancillary features to provide additional dune protection and pedestrian comfort. The locations of accessways and areas proposed for fill and vegetation are shown on plans developed by Wright-Pierce Engineers. Fill and vegetation areas are differentiated between those associated with public access and those impacted from private intervention. Typical details, cross-sections, and plan views are also included on the plans. A general description of each improvement measure/feature is provided below. Sand: Sand to be used as fill material is the singlemost important feature of any dune improvement program. The form and volume of a foredune is critical for flood control and sediment supply for eroding beaches and should be restored so that equal protection is provided across the entire foredune ridge. Although the existing foredune is composed of fine wind-blown sand, a medium-sized sand is present in and around the accessway cuts through the ridge. For fill purposes, the sand should be washed (e.g., clean of silt and clay fractions) and can vary between the fine- and medium-sized fractions. Volumes calculated for each street accessway are tabulated (Table 3) and totals approximately 13,000 cubic yards. An additional 10,000 cubic yards is required for cuts located between the street accessways (Table 5). Potential sources for sand fill were identified outside of the project area. Existing beach and dune sand is not recommended for use in this project. Sand and gravel companies can provide fill material and provide It by truck The sand could be off loaded in the entry of each street and smaller loaders or trucks would place the sand starting at the dune toe and finishing in the dune swale. The cost for sand is approximately $5.00 per cubic yard, delivered, resulting in a total project cost of approximately $115,000. Another source of sand could be dredged material from Hampton Harbor. Possible disposal methods could include direct hydraulic pumping to the dunes, creating a spoil area on land and trucking it to the site or carrying the sand to the vicinity by barge and off loading it to 4 IM C@ PC. the beach for additional handling by trucks/loaders. A Corps of Engineer 404 Permit (#11- 78-557) was issued In 1978 and subsequently used in the spring of 1979 and 1987 for the dredging of approximately 75,000 cubic yards, of which 25,000 cubic yards were satisfactory for beach nourishment. The Conservation Commission would be the most likely agent for pursuing this alternative. 3Legetaflon Salt-tolerant vegetation is critical to a dune improvement program for the purposes of stabilization and increased sand-trapping. American beachgrass is the most common species used for replanting dunes and Is commercialbr available. Typically, there are three stems to a culm. and 100 culms in a bundle. Approximately 66,800 culms (Table 4) and 22,000 culms (Table 5) have been calculated for the street accessways and areas in between, respectively. The total project need is approximately 888 bundles. At a rate of $20.00 per bundle the total cost would be $17,760 for materials. Planting methods for the beachgrass culms consist of the following: 1. Space the culms 12-24 inches apart (18 Inches is preferable). 2. Plant at a depth of 6-8 inches. 3. Plant between November 15 and April 15. 4. Fertilize with granular 10- 10- 10 or preferably three parts nitrogen to one part phosphorus. 5. Apply 80 pounds of nitrogen and 25 pounds of phosphorus per acre in the early spring. A first-year application is adequate. Alternatives to purchasing beachgrass would be transplanting existing grasses from the dune toe to ridge and swale areas or harvesting seeds from existing plants and sidecasting them. Each alternative would be more labor intensive and the rate of success for growth from seeds is unknown. Access Structures Various construction materials and designs for walkways from the street-ends to the beach are proposed. To be consistent with existing efforts, concrete patio blocks are proposed in the entry sections of the street accessways (see plan detail). These areas have firm, gravelly soils and are not subject to wind erosion. At grade pressure-treated wood walkways connected by galvanized cable, similar to that at State Line Street and preferred by the Conservation Commission, are proposed for a majority of the accessways through the swale and ridge environments. The weight of these walkways will prevent them from shifting throughout the year, yet they can be lifted to adjust to any changing form of the dune. They may be constructed in place but must be installed after the fill has been provided. 'Mey are four feet wide for pedestrian use and eight feet wide for vehicles at Haverhill Street. Elevated wood access is proposed at two locations (Amesbury and Lawrence Streets) for the purpose of allowing possible construction over existing vegetation and providing a view of the beach and dune environment. Elevated observation decks are also proposed for these sites and for Tyngsboro Street to provide resting and viewing use. Two to three feet of separation between the walkway or deck and the grade must be allowed to permit growth of dune vegetation. 5 El @C i Pin c. At-grade wooden planks are proposed for the dune toe areas north of Lawrence Street which may be prone to damage from winter stonns. These lighter structures also connected by galvanized cables could be removed during the winter at the same time trash cans are now removed. While cutting of the dune is not a problem in these areas at the present time, it may be in the future if dune growth continues. In addition, a complete access link from the dune ridge to the beach is maintained. Fencin Protection of newly planted grasses, establishment of pedestrian circulation patterns, and potential dune sand accumulation are the primary reasons for proposed sand fencing. Approximately 2,000 linear feet of fencing is proposed seaward of the dune ridge in conjunction with the planting and walkway schemes. Proposed materials consist of wood- slat-and-wire and metal fence posts. The estimated cost is $1,030.00 for 2,000 linear feet. An alternative material for the sand fence is a high modulus polymer 'Tensar" structure. Some advantages over the wood-slat-and-wire are: it will not rust, rot. or corrode: has five times the service life; has one-fourth the weight; have one-fifth the rolled diameter; and won't be broken up for firewood. The estimated cost is slightly higher than the other wood- slat fence. AncillaIX Features Several features are proposed to further protect the dunes and provide comfort to the beachgoer. Signs to identify beach access points for the handicapped and to keep off the dunes will be provided at appropriate locations. Existing trash cans will be placed on removable at-grade wooden platforms. Additional features at the entry to each accessway which may be appropriate and include spht-rail fencing to confine the entrance for pedestrians only. as well as, park benches and shade trees for relief on sunny days after long walks to-and from the beach. (Table 7). f@- @@ - 3.2 Street-end Accesswaya Specific recommendations and measurements for access features are listed by street in Table 6. This information was used to project the cost of materials for each access and the project total including sand ftll, grass, and fencing (Table 9). A list of vendors is included in Appendix B as sources for materials outlined in this report. Based on field data and observations, a priority list for dune improvements was compiled for the streets within the project area (Table 8). Factors considered include: 1) the overall distance to the beach, noting a higher need for sand fffl and,planting to protect facilities in close proximity to the ocean; 2) dune length, noting a need to protect narrow dune swale and ridge areas; and, 3) dune height. noting a need to protect low ridge or extreme cuts in the dune. Beach use was considered to a limited extent (i.e., no specific counts were made) so that walkway priorities could also be suggested. It was determined that construction priorities for the walkways would be consistent with the final ratings for dune improvements. 6 El @c ?in c. A three-year program of dune improvement and walkway construction conducted on a street-by-street basis would result in the following: Street Material Cost Year I New Hampshire $4,054.00 Newbury 2,544.26 Groveland 3,198.01 Lawrence 5,586, Subtotal $15,382.77 Year 2 Amesbury $6,882.00 Haverhill 31,922.54 Methuen 3,755.25 Andover 5,398.34 Lowell 6,997.61 Subtotal $54,955.74 Year 3 Dracut $4.676.06 Chelmsford 12,215.86 Tyngsboro 12,468.77 Nashua 13,049.88 Hudson 9,479.75 Subtotal $51,890.32 Another strategy would be to first restore and improve the dune stability and integrity and then construct walkway structures. By separating the project in this manner, costs would break down into those for dune improvements and for walkway structures. 4.0 Impact Assessment Anticipated impacts of the proposed project were evaluated on the basis of various public interest factors used by the U.S. Army Corps of Engineers. The following checklist sur=arizes the anticipated Impacts of the proposed project.

Office of the Selectman Seabrook Town Hall P. 0. box 456 Seabrook, NH 03874 Dear Abutter: Pursuant to RSA:483-A, the Town of Seabrook is informing all abutters that a New Hampshire Wetlands Board Dredge and Fill application has been subn-dtted for improvements to the Sand Dunes lying parallel to Seabrook Beach (see attached locus map). The purpose of the proposed project is to provide public access across the dunes while at the same time improving the ability of the dunes to provide a natural protective barrier from ocean storms. Public access will be improved through the construction of wooden walkways at fourteen street locations. Dune improvements will be achieved through selective additions of sand and dune grass plantings as well as erection of sand fences at specific locations. A copy of the proposal and plan are on file at the Town Hall for your review. Any questions, concerns or recommendations should be sent in writing to the Selectman's Office and Chairman of the New Hampshire Wetlands Board by writing: Delbert Downin& Chairman N. H.
