The Riverton City Council held a nearly three-hour public hearing on a proposed Heat Resilience Plan, developed by the mayor's office and Department of Public Health in response to two severe summers that strained the power grid and increased emergency room visits. Staff presented data showing low-income neighborhoods experience surface temperatures 6 to 8 degrees Celsius higher than leafier districts. The plan would convert twelve public buildings into cooling centers, plant 18,000 street trees over five years, require reflective roofing on large new developments, mandate common-area cooling in large rental complexes during heat emergencies, fund shade structures for small businesses, and add shaded seating at 150 bus stops. Supporters, including a physician, a sanitation workers' union representative, South Ward residents, school leaders, and a nonprofit director, emphasized unequal health burdens and the disruption heat causes for children and families. Critics, including apartment owners and a downtown merchants' group, argued the plan was too broad, too fast, and costly, while two council members questioned maintenance funding. Budget staff projected a five-year cost of 48 million dollars drawn from an anticipated state grant, bonds, reallocated funds, and uncertain sources leaving an 8 million dollar gap. Implementation questions covered access, accessibility, and tree survival. The council voted 5 to 2 against immediate adoption, instead requesting a narrower first-phase package within sixty days.

Answer A is a well-structured, comprehensive summary that covers nearly all the key elements of the passage: the hearing context, the plan's components, supporter arguments (with specific stakeholder groups named), critic objections, the $48 million budget with its funding breakdown and $8 million gap, implementation concerns, and the 5-2 vote outcome with the sixty-day directive. It maintains a neutral tone throughout and avoids invented details. The word count is within the required 180–230 range. Its main weakness is that it is slightly dense and list-heavy in places, but it remains coherent and informative.
