Avalon Hayes

The firm was tasked by AvalonBay Communities, Inc. to provide civil engineering design services for the preparation of site and offsite improvement plans for 180 apartment units, with approximately 3,300 SF of ground floor level retail and a podium style building with below-grade parking. The project also included construction of a new public street, Hickory Street, between Laguna and Octavia. The site was formerly used for open space and surface parking.

The project included design of civil improvements for both on and off-site areas. On-site Improvement plans included improvements located within Parcel P and along street frontages. Off-site plans included design of the civil improvements for Hickory Street which was located within the City’s right-of-way. Work associated with the Hickory Street and off-site improvements were designed and specified in accordance with the City and County of San Francisco (CCSF) Standard Specifications and Plans.

A Stormwater Control Plan was prepared to demonstrate compliance with the City’s Ordinance and identify appropriate best management practices (BMPs). BMPs implemented include a dry well, vegetative roof, flow-through planters, and bioretention areas.

AGS assembled final civil site improvement drawings and technical specifications for submittal to the Owner’s Representative for inclusion into bid documents. The firm also provided interpretation of the civil construction plans during the bid process and coordinated civil addenda as required. Construction began in June 2013 and was completed in November 2014. This project is seeking to achieve LEED certification.

AvalonBay Communities, Inc. is in the business of developing, redeveloping, acquiring and managing high-quality apartment communities in the high barrier-to-entry markets nationwide.

Construction began June 2013 and was completed in 2014.

LID measures proposed for the AvalonBay Hayes Valley (AVH) Project include the use of flow-through planters with underdrains at the podium courtyard level and a dry well beneath the entry slab at the eastern end of the project. All LID BMPs are designed to receive and treat direct roof runoff. LID BMPs proposed for the AHV Project Offsite improvements include the use of permeable pavement in between street tree wells behind the curb. The proposed flow-through planters, dry wells, and permeable pavement were sized using the San Francisco Public Utilities Commission’s (SFPUC) Combined Sewer System BMP Sizing Calculator for Quantity Control Version 2.
