Stockton Subdivision Bonds, Insurance and Encroachment Requirements for Developers

The agreement split improvement security into separate instruments rather than one bond at full cost. With a public improvements cost that made each 50 percent instrument $1,580,670, the subdivider posted the following.

• Faithful performance: 50 percent of the public improvements cost
• Labor and materials: a separate 50 percent of the public improvements cost
• Monuments: a cash bond of $52,000 for 26 monuments
• Sureties: corporate sureties admitted in California

Under the agreement, performance security can be released after the City accepts the work if security of at least 10 percent of the public improvements cost is retained, or a warranty security is given, to guarantee and warrant the work for one year after acceptance. Labor and materials security is released 60 days after the Notice of Completion is recorded if no claims are filed, and the monument cash bond is released under Government Code Section 66497.

For a surety, the retention is the part that lingers. A 10 percent warranty instrument stays open for a year after acceptance on every map, so a builder recording several units in sequence carries a stack of warranty obligations alongside new performance bonds. Track acceptance dates closely, because release depends on the City's acceptance and recording steps rather than on construction completion alone.

Exhibit B of the agreement set insurance for the subdivider, and the subdivider must pass the same requirements down to its contractor. The subdivider also defends and indemnifies the City, except for the City's sole negligence or willful misconduct.

• General liability on ISO CG 00 01, occurrence form: $2,000,000 per occurrence including products and completed operations, with a per-project aggregate (CG 25 03 or CG 25 04) or an aggregate twice the occurrence limit
• Auto on CA 00 01, any auto (Code 1): $1,000,000
• Workers' compensation at statutory limits and employer's liability at $1,000,000
• Additional insured: City of Stockton, its officers, officials, employees and volunteers, on CG 20 10 11 85 or equivalent
• Primary and noncontributory wording at least as broad as CG 20 01 04 13, with no sole-negligence limitation
• Waiver of subrogation, insurers rated A.M. Best A:VII or better and a $25,000 cap on any deductible or SIR without written approval
• Claims-made coverage maintained for five years after completion or a five-year extended reporting period

Stockton's Risk Services division sets insurance requirements for City contracts and reviews and approves all bonds and evidence of insurance, including certificates and endorsements. Its page lists endorsements that may be required: additional insured, completed operations, primary and waiver of subrogation on general liability, plus auto, workers' compensation with a waiver of subrogation, professional, pollution and cyber coverage. It gives the additional insured wording above or accepts blanket wording such as "per written contract."

The page lists no limits, so the limits in a specific agreement or contract control. A common delay is a certificate that shows the right limits but omits an endorsement form number or uses a narrower primary wording than the agreement requires. Send the endorsements with the certificate rather than after the City asks for them.

The City requires an encroachment permit for work in its right-of-way. Its process asks applicants to provide insurance documents, pay permit fees and a security deposit and make sure every contractor and subcontractor holds a City business license. The application adds that a certificate of insurance must be on file with the City Risk Manager before the permit issues and that the applicant agrees to indemnify and hold the City harmless against losses from injury to persons or property.

The application also makes the applicant responsible for replacing damaged sidewalk, curb and gutter adjacent to the parcel and for having any disturbed survey monuments reset by a licensed land surveyor. Neither the form nor the web page states the deposit amount, and the form's fee lines are blank, so confirm the deposit and any insurance limits with the City for your scope. Whether the indemnity qualifies as an insured contract under a general liability form depends on the policy wording.

Stockton applies SB 5's 200-year, urban level of flood protection findings to tentative maps for subdivisions and to new residential structures, with code changes that apply to permits issued after July 2, 2016. The 200-year floodplain includes a significant portion of the City's western side near I-5, and the City states that these rules do not by themselves trigger a flood insurance requirement, which leaves flood on builders risk as a separate decision.

Habitat mitigation runs through the San Joaquin County Multi-Species Habitat Conservation and Open Space Plan, which the City has participated in since 2001; participation is voluntary and offers a fee in place of project-by-project negotiation. A December 2025 staff report proposed raising the Agricultural and Natural Habitat fee classification from $16,492 in 2025 to $17,868 for 2026, and the final Council action should be confirmed with the City. Map and plan check costs add up too: the City lists a $3,685 final map filing fee and plan check starting at $82.50 plus 5.5 percent of the first $100,000 of construction cost.

Projects on Port of Stockton land fall under the Stockton Port District, a California special district designated Foreign Trade Zone 231 with 400-plus acres approved for new development, and can carry the Port's own insurance terms on top of City permits.
