The authority shall establish the following time limits for that portion of the project area described in paragraph (2) of subdivision (a) of Section 8180 (the R Street Area):

1. (a) A time limit on establishing or incurring loans, advances, and indebtedness to be paid for with proceeds of property taxes received pursuant to Section 8183, which limit may not exceed December 31, 2022. However, this limit may be extended by the authority for 10 additional years if the authority finds, based upon substantial evidence, both of the following:

   1. (1) Significant blight remains within the R Street Area.

   2. (2) This blight cannot be eliminated without the establishment of additional debt.

      This limit shall not prevent the authority from incurring debt, to be paid from that portion of the set-aside collected pursuant to Section 8191 from properties within the R Street Area, in order to either fulfill the authority’s obligations pursuant to Section 8193.1, or to refinance, refund, or restructure an indebtedness after the time limits if the indebtedness is not increased and the time during which the indebtedness is to be repaid does not exceed the date on which the indebtedness would have been paid. The loans, advances, or indebtedness may be repaid over a period of time longer than these time limits.

2. (b) A time limit on authority activities within the R Street Area, which limit may not exceed December 31, 2032. However, the authority may pay previously incurred indebtedness and enforce existing covenants, contracts, and other obligations. This time limit shall not prevent the authority from fulfilling the authority’s obligations pursuant to Section 8193.1.
3. (c) A time limit on receipt of property taxes pursuant to Section 8183 from properties within the R Street Area, which limit may not exceed December 31, 2047. However, this limit shall not be construed to affect the validity or payment of any bond, loans, advances, indebtedness or other obligation, or the right to receive taxes pursuant to Section 8183 to pay the loans, advances, indebtedness or other obligation to repay bonds, loans, advances, and indebtedness within those 45 years.
4. (d) A time limit on the commencement of eminent domain proceedings to acquire property within the R Street Area, which limit may not exceed December 31, 2014, unless expressly extended by formal action of the authority. However, in no case shall the limit be extended beyond the time limit set in subdivision (b).
