AI Contract Overview

The Otay Reed Mitigation Project aims to compensate for past and future stormwater channel maintenance impacts within the Otay Valley Regional Park in California. Covering 6.48 acres on City-owned parcels, the project involves restoring wetland habitats, upland scrub areas, and establishing a weed-free buffer around the site. Implementation includes soil excavation, grading to match adjacent wetlands, invasive species removal, and planting native species characteristic of southern willow scrub, mule fat scrub, alkali marsh, and maritime succulent scrub. The work will be confined to designated areas, with a schedule that includes an installation phase followed by a 120-day plant establishment maintenance period. The project also requires soil testing for contamination, erosion control measures, temporary irrigation, hydroseeding, and ongoing weed management to ensure successful habitat restoration. Contractor responsibilities encompass demarcating work limits, identifying buried utilities, executing earthwork activities, developing a Water Pollution Control Plan, installing erosion BMPs, and maintaining plantings through watering and weed control during the establishment period. Large non-native trees that are difficult to remove may be killed in place and left on site. Soil testing will determine if contaminated soils need removal, and all work must adhere to environmental guidelines and best practices. The project is set within a framework of a five-year monitoring period, which is managed under a separate contract. The contract size ranges from $500,000 to $1.5 million, with responses due by July 31, 2024, and primary contact being Abel Martinez.

Full Description

The Otay Reed Mitigation Project (Project) was designed to provide compensatory mitigation for past City of San Diego (City) Stormwater Department (SWD) channel maintenance impacts and to also provide Advanced Permittee Responsible Mitigation (APRM) for future stormwater channel maintenance projects identified in the City's Municipal Waterways Maintenance Plan and associated Final Environmental Impact Report (MWMP; Dudek 2020). The Project encompasses 6.48 acres and is located on two City-owned parcels (Assessor Parcel Numbers 62407026 and 62407022) within the Otay Valley Regional Park (OVRP) and is within the City's Multiple Species Conservation Program's (MSCP; City 1997) Multi-Habitat Planning Area (MHPA). The 6.48-acre Project area is composed of 5.04 acres of wetland habitat mitigation areas, 0.17 acre of an upland mitigation area, 1.21 acres of a weed free buffer area, a 0.01-acre SDG&E utility pole guy wire access area, and a 0.07-acre staging area (including 0.02-acre overlap with the proposed weed free buffer area).Implementation will involve soil excavation (and removal) and grading to lower the elevation to that of the adjacent wetland habitat along the northern and southern banks of the Otay River, treatment and removal of invasive species, and installation of native container plants and seed. Plant species characteristic of southern willow scrub, mule fat scrub, and cismontane alkali marsh will be installed within the riverbed and adjacent wetland establishment/re-establishment and rehabilitation areas. Upland scrub plant species characteristic of maritime succulent scrub will be installed on the upland slope that will be created by grading activities for the wetland establishment/re-establishment portion of the site. In addition, a weed-free buffer of 50 feet will be maintained around the Otay Reed mitigation site (only on City-owned property). All work shall be conducted within the designated mitigation site and staging area at locations identified on the Construction Documents. The work schedule is defined by an installation phase and a post-construction 120-day plant establishment maintenance period (Project contract period). The 5-year maintenance and monitoring period described in the Project's Habitat Mitigation and Monitoring Plan (HMMP; August 2023) will be completed under a separate contract and is nota part of this Project contract period.Contractor services required of this scope of work include demarcation of work limits; determining the location of any buried utilities prior to any earth disturbance; non-native plant (weed) removal (prior to or during grading) following current shot-hole borer guidelines provided by the University of California Agriculture and Natural Resources (UCANR; 2017 and2020); excavation and grading; development of a Water Pollution Control Plan (WPCP); installation and maintenance of erosion control best management practices (BMPs) per the requirements of the WPCP; installation of a temporary irrigation system, container plants and cuttings; and hydroseed application. Large non-native trees that are too difficult to removefrom the designated enhancement area (or may cause too much impact from felling and removal to native plants) may be killed in-place and left on site. Soils will be tested for potential contamination during grading. Any contaminated soils will be removed from the area and disposed of at an approved disposal facility to preserve public health. Upon completion of installation, the Contractor shall conduct the 120-day plant establishment maintenance period; provide watering (via temporary irrigation system supplied by a water truck) for plant material; conduct regular weed control within the mitigation site and buffer; and implementmaintenance measures (and remedial actions as needed) for the duration of the contract period to ensure specified plant survivorship and successful control of non-native plant species.
