Seabrook city and its Economic Development Corporation reviewed schematic designs Tuesday night for converting the former wastewater treatment plant into an elevated, resiliency‑focused Bayside Park and for a companion Main Street streetscape upgrade.

Kimley‑Horn designer Christina Malik summarized three stakeholder meetings and presented a consolidated concept that raises the park site to about elevation 12, builds a small event plaza and ‘‘veil pavilion,’’ creates a nature‑play area and open lawn, restores coastal prairie plantings down the slope to the water, and adds an enhanced vegetated shoreline. The design preserves the existing lift station on the site but proposes a painted or themed concrete enclosure to screen the equipment.

The schematic shows a mobile restroom — a trailer‑style unit elevated on a pad and accessed by ramps to meet Americans with Disabilities Act requirements — located near Main Street where it would serve both park visitors and people fishing along the waterfront. Malik said the stakeholder group recommended a mobile restroom because it can be moved ahead of storms; the design team also suggested a recessed ‘‘corral’’ or enclosure and a grass‑pave or other permeable surface for the trailer to sit on. Kimley‑Horn included electrical service and resilient, removable fabric shade for the pavilion in the high‑level cost estimate.

Stakeholders emphasized a nature education focus rather than a conventional playground, a small event capacity (about 50 people or fewer) for acoustic programs or classes, and keeping parking out of the park footprint so the site can prioritize natural amenities. Malik said the team evaluated renovating the existing wastewater office but found renovation cost‑prohibitive, which helped prompt the mobile restroom and raised‑elevation approach.

On shoreline and planting, the presentation noted involvement from regional environmental partners and interest in native coastal plantings and living shoreline techniques. A speaker identified as representing Galveston Bay Foundation and estuary partners told the council those groups are actively involved with removing invasive species and replacing them with native shoreline plantings.

For the adjacent Main Street corridor, Kimley‑Horn proposed keeping all work inside the existing roadway footprint while reallocating lane space to create additional parking (including head‑in stalls near the park), shaded seating nodes, widened sidewalks, bump‑outs with clustered trees for traffic calming, and a marked crosswalk at the park entrance. The streetscape concept retains overhead utilities, the consultant said, to avoid the high cost of undergrounding. The consultant presented a rough order‑of‑magnitude construction estimate for the streetscape segment shown at about $1.8 million, and included escalation for a 24‑month delay; the park elements and amenities were presented in separate cost buckets with the mobile restroom cost shown in the schematic estimate.

Stakeholder members who took the podium endorsed the consolidated design and thanked Kimley‑Horn staff and city staff for incorporating feedback. Malik closed by outlining typical next steps: identifying funding and phasing, design development, construction documents, permitting, and a two‑year design-to‑construction schedule as a general planning horizon.

The council and EDC did not take formal action on the schematic tonight; the presentation was a workshop update.
