Bay Engineering, Inc. performed professional services for a six-story proposed 237 residential apartment building. Responsibilities included site layout and design of onsite stormwater management facilities, step pool conveyance system and stream restoration. The site incorporates the use of nonstructural practices (sheet flow to conservation areas), alternative surfaces (permeable pavers), and microscale practices (micro-bioretention areas with enhanced filters) to meet stormwater management requirements for the development. This SPSC system is designed to convey runoff from the 100-year storm for the drainage area to its downstream end. The proposed stream improvements incorporate a SPSC system through the main stream channel, as well as boulder weirs to create plunge pools at two headwalls that discharge runoff from the west side of Admiral Cochrane Drive. The design is an extension of the downstream Wilelinor SPSC system, to alleviate any erosion problem throughout the length of improvements, and to slow down flows into Church Creek. A detailed watershed and stream study was conducted on the offsite receiving stream, including a detailed hydrogolical study and HEC-RAS analysis of both existing and post-development conditions.

Bay Engineering, Inc. performed professional services for phased building additions totaling approx. 15,000 square feet and 13.2 acres and expanding the existing parking by 48,000 square feet. The existing stormwater and storm drain systems are to be modified to meet the MDE 2000 standards. Designed entrance improvements and added addition exit lane to existing church. Provided hydrologic and hydraulic analysis of existing onsite storm drain system and designed onsite micro-bio-retention area for qualitative treatment of stormwater runoff from entrance improvements. Performed outfall analysis to determine impacts of entrance improvements on existing downstream storm drainage. Responsibilities included the design of entrance improvements / lane expansion and required stormwater facilities to manage said improvements.
