PHASE II ENVIRONMENTAL SITE ASSESSMENT - PROJECT NO. 7607 -
STORMWATER CAPTURE AND INFILTRATION PROJECT AND PROJECT NO. 7359 - HERMOSILLO PARK REHABILITATION – ENGINEER’S REPORT NO. 24-08
Background:
The City has received Measure W Funds for the Project No. 7607 stormwater capture and infiltration project (Project) from the Lower San Gabriel River Watershed Management Program (LSGR WMP) Group. The project will capture dry-weather flows at two locations. The first location is an existing storm drain on Horst Avenue adjacent to the park. The second location is within the park from an existing Los Angeles County Flood Control District storm drain culvert. Up to 50 cubic feet per second (cfs) of combined dry-weather flows from both the storm drain and storm drain culvert will be diverted and stored in underground infiltration gallery/detention basins. The underground basins provide storage for up to 11.8 acre-feet of flow, approximately the size of six Olympic size swimming pools. These improvements are to be constructed in the northern half of the park, and includes the appurtenant diversion piping, pumps, and a treatment system to supply recycled water for onsite irrigation.
The City has also received Proposition 68 Funds for the rehabilitation of Hermosillo Park (Project). The project will rehabilitate Hermosillo Park in its entirety which includes the construction of a new reception building, new turf grass, irrigation, landscaping, hardscape, parking lot, playground area, basketball courts, soccer and multi-use fields and lighting for the fields.

2 Construction Management and Inspection:
On March 4, 2024, Request For Proposals 24-759, staff solicited proposals from consulting firms interested in providing construction management and inspection services for the Project. On March 25, 2024, the City received three proposals from the following firms:
1. Transtech Engineers
2. Psomas
3. Z&K Consultants
Staff reviewed the proposals for understanding of the project, experience of their proposed team on similar projects, and references. Staff recommends awarding a professional services agreement for Construction Management and Inspection services to Transtech Engineers based upon the quality of their proposal.
Phase II Environmental Site Assessment (ESA):
On October 16, 2023, the City executed a professional services agreement with Rincon Consultants for Phase I ESA for the project. The Phase I ESA report was completed on December 14, 2023. A proposal for Phase 2 ESA was provided by Rincon Consultants for further investigation into current site conditions, including soil conditions.
The contract authority for Rincon’s services are as follows:
Professional Services Agreement (10/16/2023): $14,705 Amendment No. 1: $14,225 Amendment No. 2 (proposed): $14,705 Due to a clerical error, Amendment No. 1 was executed for less than the full amount required for completion of Phase II ESA. Amendment No. 1 was executed for a total contract amount of $28,930 rather than a total amount of $28,930 and a total contract amount of $43,635. Therefore amendment No. 2 in the amount of $14,705 is necessary to fully amend the contract to complete the Phase II ESA investigation and report.
Fiscal Impact:
The project is funded with the following funds:
Measure W $20,200,000
Proposition 68 $8,500,000
Measure A $2,200,000
Park Renovation Funds $75,000
