Neighbors raise stormwater and sewer concerns; Brentwood board tables 8832 Moritz

The Brentwood Architectural Review Board tabled review of a proposed two‑story house at 8832 Moritz after neighborhood members raised questions about stormwater mitigation and potential sanitary sewer impacts.

Michelle Dorring, representing MRM Manland Development Group, presented plans for a two‑story residence with white vinyl siding, board‑and‑batten accents, black windows, and stone details. Board members discussed a revised site plan showing the house set back approximately 28 feet from the front property line and noted the presence of an MSD easement that constrains where the house may be placed.

A longtime neighbor, Michael Conley of 8833 Bridgeport, said he and his wife have lived nearby for decades and expressed concern about water discharge and sanitary sewer backups in the area. Conley said he worried that detention and grading work could change how water moves across backyards. He also asked whether an MSD variance or previous MSD work explained why nearby houses were set back from the street.

The board and staff explained that MSD and city stormwater rules govern detention, that the city’s ordinance requires civil‑engineer review for certain increases in impervious area, and that smaller net increases (up to 2,000 square feet) can often be handled with on‑site retention tanks. A city representative noted, "I do have I do have a letter from MSD approving this project." The board clarified that detention tanks are typically placed in rear yards, include designed overflow popups and must meet separation from property lines.

Because the applicant’s architect was not present to make immediate changes and neighbors wanted further clarification of grading and overflow locations, the board moved and voted to table the 8832 Moritz application and asked the applicant to return with revised drawings and engineering details addressing roof slope, grading and stormwater mitigation.
