Title
Consider and take action on a resolution authorizing a professional services agreement with LJA Engineering, Inc. (LJA) for design work related to the Bay Ridge Flood Reduction Project, Phase II (DR 2005) in an amount not to exceed $263,000 (Director of Engineering)

One of the areas of concern discussed during the public meeting and again when presenting to Council was the subdivision’s drainage system deficiencies related to the existing detention pond.
Based on the LJA Study, City Staff created a potential drainage improvement project. This project was included as part of a list of potential drainage projects outlined on the City’s recently passed May 2019 General Obligation Bond Referendum.
For this contract, LJA will provide engineering services for a 42,000 Gallon per Minute Stormwater Pump Station to be added to the existing detention pond within the Bay Ridge Subdivision. This PSA will allow for the review and/or design of:
