Planning commission recommends approval of Northwest Highway daycare after sound, traffic and screening commitments

The Village of Mount Prospect Planning & Zoning Commission voted to recommend the village board approve a conditional use for a daycare at 1040 W. Northwest Highway after petitioners agreed to several mitigation measures intended to address neighbors' noise, traffic and screening concerns.

Staff summarized revisions made since the prior board denial: relocation of the trash enclosure farther into the site, an 8-foot privacy (sound) fence around the outdoor play area, clarified parking and circulation plans, and land-banked parking stalls that can be converted if on-site demand increases. Staff also recommended a condition requiring the petitioner's sound engineer to provide a certification of the fence materials and to perform real-world noise testing within 90 days after issuance of a temporary certificate of occupancy; if testing shows additional mitigation is needed, staff may require further measures including landscaping, additional fencing or a reduction in the number of children permitted outside at a time.

Petitioners' representatives described the operation and the scale of improvements. “The idea here is we are putting in a daycare in a space that needs, in a city that needs a daycare,” the petitioner said, stressing indoor-play options and a larger-than-average outdoor play area. Acoustical consultant Steve Thunder told the commission, “For sound to be annoying, we need it to be a clearly audible sound, which would be about 5 dB above ambient noise,” and said the modeled output with the 8-foot STC-rated fence would remain below that commonly used 5 dB impact threshold.

Traffic consultant Kevin Heffernan said the proposed single ingress/egress and one-way circulation should keep queuing on Northwest Highway to a minimum. He described using ITE trip-generation data plus local counts to model operations and said the design produces on-site queuing capacity and acceptable peak delays; staff and the village engineer reviewed those conclusions.

Residents who live immediately adjacent to the site said they worry about peak-period stacking, cut-through traffic on neighborhood streets, vehicle headlights and garbage odors. “All of our properties are surrounding this property,” one resident said, noting that heavy drop-off and pick-up activity would directly affect backyard enjoyment. Petitioners agreed to additional evergreen screening and to work with staff on operations and enforcement measures. Staff also noted tools exist to address off-site parking or operational violations through code compliance if necessary.

At the commission motion to recommend approval, members adopted staff's conditions and added a requirement for continuous six-foot screening along the northern property line (to be determined by the director of community development and allowing evergreen plantings where appropriate). The roll call recorded Aye votes from Commissioners Simsac, Weir, Olsen, Beatty and Chairman Donnelly; Commissioner Rogers voted No. The motion carried and the case will go to the village board on June 2 for final action.

The commission’s recommendation includes: limitation of outdoor play to two classrooms or 50 children at any one time between 9 a.m. and 5 p.m., restricted passive outdoor activity (reduced usage) from 5 p.m. to 7 p.m., an 8-foot STC-rated privacy/sound fence around the outdoor play area, certification of fence materials and post-construction noise testing within 90 days of a TCO, relocation and screening of the trash enclosure, a requirement that any parking land-bank convert on staff direction if on-site demand rises, and additional continuous screening along the north property line subject to staff review and approval.

Next steps: the village board will consider the commission’s positive recommendation at its June 2 meeting. If the board approves, the conditions require follow-up testing and possible mitigation if measured noise exceeds modeled levels.
