A PPROPRIATION C OMMITTEE S PECIAL T OWN M EETINGS 2017-2 & 3 O CTOBER 10, 2017 MSBA Reimbursement Construction costs for the new school, including site work, are projected to be approximately $52,900,000, or $482 per sq. ft. The MSBA reimbursement represents 35.79% of not more than $46,200,000 in construc- tion costs. The basis of the MSBA reimbursement excludes legal fees, site costs in excess of 8% of the total building cost, construction costs in excess of $326 per sq. ft. plus eligible demolition and abatement costs, other miscellaneous ineligible construction costs, costs associated with mailing and moving, costs in excess of the $1,200 per student allowance for fixtures, furniture, and equipment, costs in excess of the $1,200 per student allowance for technology, amounts. Building emissions and energy use The new Hastings is being designed for both excellent building air quality and low lifecycle energy costs. Although these two goals tend to oppose each other, the design achieves a good compromise, in part by employing geothermal wells for heating and cooling, at a cost premium of $2,200,000 over a conventional air-cooled chiller and condensing boiler plant. The site energy consumption by end-use at Hastings is pro- jected to be 24.1 kBTU/SF-yr EUI (energy use index, in kBTU per sq.ft. per year), compared to 39.7 kBTU/SF-yr for the conventional HVAC system. The savings reflect primarily more efficient space heat- ing. For comparison, historical EUIs at other Lexington elementary schools are 54.8 kBTU/SF-yr at Es- tabrook, 48.4 at Harrington, and 39.3 at Fiske which employs geothermal heating. These numbers do not take on-site solar panel energy generation into account. The new building will have the capacity to install rooftop and parking lot canopy solar panels that could potentially generate as much as 901,977 kWhr/yr. The Debt Exclusion Referendum The Board of Selectmen has voted 4-1 to present a motion under this article in which the appropriation is contingent on approval of a Proposition 2½ debt exclusion referendum to be held in late November or early December. Should the debt exclusion be approved, property taxes will be higher than otherwise allowed under Propo- sition 2½ for the life of the debt. Annual debt service payments for the new Hastings are projected to reach $3,572,415 in FY2021, and to decrease in later years. Some of the excluded debt service may be covered through mitigation transfers from the Capital Stabilization Fund. See the discussion in the Introduction. The Committee recommends approval of this request (7-0-2). Article 2016-2.3: Appropriate Design Funds for Lexington Children's Place/20 Pelham Road $2,500,000 Excluded Debt Approve (7-0-2) This article seeks $2,500,000 for design, engineering and architectural services for the proposed new Lex- ing 18,850 square feet of floor area and 7 classrooms, is estimated to cost around $15M. The LCP provides services to preschool children (ages 2 years 9 months to 5 years old), including children with special needs who qualify under the state mandate for free educational services, and children without special needs whose families pay tuition. The LCP currently shares space in the Harrington School and in the old Harrington School building where the School Central Office (CO) is located. As of the end of the 2016-2017 school year, LCP had an enrollment of 81 students, of which 41 students attended one slot per 9
