Plan Commission approves Capstone subdivision primary plat; neighbors press wetland and traffic concerns

The Plan Commission approved the primary plat for Capstone, a multi‑phase residential development by Diamond Peak Group, after the petitioner described phase 1 and 2 (89 lots at 80 by 135 feet) and community amenities including a central park and putting green.

Michael Hervers said the project will use higher‑end materials — ‘‘100% LP smart siding’’ with minimal vinyl and mature landscaping — and will preserve or enhance on‑site wetlands where practical. "All of the homes here will be 100% LP smart siding. There will not be any vinyl on our homes," Hervers said.

Neighbors who back up to the proposed phases raised concerns about standing water, edge‑of‑field swales and possible changes to historic drainage routes; several asked for stronger assurances on pond sizing and engineering during site review. The city’s third‑party stormwater reviewer said the proposed basins and detention will be sized to meet the city’s stringent release rates and that engineering comments had been exchanged with the petitioner’s team.

Planning staff recommended approval and the commission voted to approve the primary plat; subsequent secondary plats and site development reviews will address detailed stormwater mitigation, perimeter buffering, and construction timing.

Petitioner representatives told the commission they would continue to work with engineering staff, preserve higher quality wetlands, enlarge on‑site basins where required and maintain sightlines for the existing Gallery subdivision. The developer also said it would coordinate with INDOT and city staff about intersection upgrades near 133rd and Grant Street as traffic considerations move from planning to design.
