(b) an evaluation of each parcel proposed for addition or deletion to the unit based on the analysis under paragraph (1); 
(c) an assessment of the impact of potential boundary adjustments taking into consideration the factors in paragraph (c)  as well as the effect of the adjustments on the local communities and surrounding area.
