this subsection, with the National Flood Insurance Program
standards that are anticipated to be applicable to the Sac-
ramento area following expiration of the period set by

(G) the City and County of Sacramento have each pro-
vided assurances to the Congress that they will not des-
ignate any increases in urbanization beyond lands already

of their discretion to approve new development they will
give careful consideration to—

to all buyers of new structures;

(iii) retention of natural floodways; and

ments now in effect for the Sacramento area for the limited
