<br />mitigate the adverse effect:; upon the wetlands...
<br />In accordance with-Executivc order 11990, and based
<br />on previously nested cpnsiderat ions, it has been determined
<br />that there is no practicable alternative to the
<br />proposic ne:, construction in t ie wetland:- and that.
<br />the proposed action includes all practicable measures
<br />t,) minimize harm to th• wetlands wl;ich may result
<br />from --,uch use."
<br />The appen(lized .1 -et ters i t,l,, :3Pencics listed above

<br />we also reconan:-nd that severer design features be included as

<br />1. Rcmova.l o" the di :c, and till area <,outh of North canal
<br />and west of tha align.1ient, proposed by the applicant as partial
<br />mitigation for wetland, destruction, woull provide the best
<br />be -,.if -fir for f i::h and v i ldl if e:• if excavated to 0.0-1.0 feet
<br />mean sc�a level. This �:oul_d create intertidal habitat conducive
<br />to establishment of reg man roves and utilization by estuarine
<br />organis;33-: and wading bird.:.
<br />2. The dike north of tio>=th Canal and west of the alignment
<br />should l.1kewise be. removed, thus providing approximately 3/4
<br />acre of additional intertidal arca adjacent to the existing
<br />tidal ditch.
