DREDGING AND TRAMSPLANTJMG PROCEDURE:

The following steps •111 be perfor•ed before or dur1ng the trans-plan~:

The best •ate.rial for 1•prov1ng the eel-grass trJ!lsp.l•nt area will be deteraine_d in consulta-tion •1th the resource agencies. ·

2. Prior to dredging, a1 test transplant_ will be perfor111d to deter•1ne the be$~ aeans of te~porar11y holdJng eelgrass before the ·tr,ansp-lant. ,

3. An eelgrass survey of the area to be effe::tcd ,.w111 be perforaed prio'r to dredging for th~ purpose of deter-aining the actual impact on eelgrass beds.

4. Prior to dredging the effected area. 52.500 shoots w111 be obtained fro• the effected ar.ea and teaporar11~ placed in the area d.es1gnated for ter.iporary ~\orage.

s. The dredg 1ng co~tractor, -under superv ts ton by the County and its 1'1P~esen~t1ves. shall d1"edge and place sufficient sandy •ater1a1 to ,obtain the required ttans~ planting area.

&. With·tn one week of dredging 1n the effected area, an eelgrass survey •111 be perforaed 1n er-der to detlraine 'the re•• in 1ng ee-1gras5.

1~ Ee'grass shall be transplanted using a bundle/anchor techn·tque. A tota.1 ofl.500 planting un1_ts -(based on an affe~ted ar~a.of 14.000 sq. ft.) consisting of 15 ,shoo'ts '!)er bundle wi 11 be planted on 2 foot center-:s. Transpla~ting will occur abou_t. but no sooner than. 30 d_ay!: after dredgfng un-less aod1fted by the resource agentie~.

Alternatively. 1f suitable sandy lia~erial can be ~laced to 1•-pr-ove 1he substrate and a 1 lDwed to st1utd ·for a •1n1 •u11 of 60 days pr1of- to, dredging the eelgrass •rea. then th~ effected eelgrass can be transplanted directly to the 1 eproved area and te•por1.ry trnnsplant,1ng wnl not be necessary. lf this occurs then: step 2 above w111 not &>e requit>ed; step 4 w11~1 involve t~ansplant1ng ct1r,ectly to the improved: ,area: and 1n step 7. transplanting w-n l occur no ~ooncr than 60 days •·fter •a-ter·ia 1 h•~ :11-ien pl aeed- to 1•prove the substl'"ate.
