KENNEBUNK — Voters in Regional School Unit 21 passed the $56.5 million renovation bond for Kennebunk High School, Kennebunkport Consolidated School and Mildred L. Day School on Tuesday, with a vote of 3,932 to 2,398.

Voters opposed a more expansive $75 million renovation bond by a margin of two-thirds in January 2014.

The project would address safety concerns at all three schools as well as address space concerns at the aging high school building, and expand classroom sizes to meet state recommendations.

All three towns in the district approved the bond individually. Kennebunkport supported the bond 874-589, Arundel voted 488-347 in favor of the bond and Kennebunk voted 2,570-1,462. A vote to form a withdrawal committee in Kennebunkport failed 524-928.

Superintendent of Schools Kevin Crowley heralded the vote as a win for the RSU.

“The results represent a win, win, win for the towns ot Kennebunk, Kennebunkport and Arundel,” Crowley wrote in an email. “The reasons for this are clear. The infrastructure of our schools will be set for the next 30-35 years; the three towns which make up the RSU are stronger together than they are apart ”¦ We thank the citizens of all three towns for the trust they have shown in us ”“ we will not let you down.”

RSU 21 voters also approved the $39 million operating budget for the RSU. For a $200,000 home, property taxes will rise $28 in Arundel, $16 in Kennebunk and $34 in Kennebunkport. The $56.5 million renovation bond will increase property taxes for a $200,000 home by $146.46 in Arundel, $153.12 in Kennebunk and $139.52 in Kennebunkport.
