The department shall send a copy of the report to the subdivider at least three days before the public hearing. (GC §66452.3)

B.
Planning Commission and City Council Actions.

For all subdivisions, the planning commission shall make its recommendation to the city council, within 50 days after the tentative map was accepted for filing (accepted as complete under the Permit Streamlining Act), for approval, conditional approval or denial of the tentative map; and within 30 days after the planning commission makes its recommendation, the city council shall approve, conditionally approve, or deny the tentative map. (GC §§66452.1(a), (c), 66452.2)

The time periods specified in subsection (B)(1) of this section begin after certification of the environmental impact report, adoption of a negative declaration, or a determination that the project is exempt from the requirements of the California Environmental Quality Act. (GC §66452.1(c))

If no action is taken within these time limits or an extension mutually approved under Piedmont Municipal Code section 19.26, the tentative map is deemed approved insofar as it complies with the general plan, an applicable specific plan, this chapter, including city-approved policies, standards and requirements, the Subdivision Manual, the Piedmont Zoning Code, and the Subdivision Map Act. (GC §66452.4)

29

C.
Approval.

Before approving a tentative map or tentative parcel map, the city council must first approve the design review application and any required variances.

The city council may approve or conditionally approve a tentative map or tentative parcel map if it finds all of the following: (GC §§66473.5, 66474)

a.
The proposed map is consistent with the general plan, any policy or guideline implementing the general plan, other applicable provisions of the Piedmont Municipal Code and the Subdivision Manual;

b.
The site is physically suitable for the type of development;

c.
The site is physically suitable for the proposed density of

development;

d.
The design of the subdivision or the proposed improvements will not cause substantial environmental damage or substantially and avoidably injure fish or wildlife or their habitat. (Notwithstanding the foregoing, the city council may approve such a tentative map if an environmental impact report was prepared with respect to the project and a statement of overriding considerations was made to the effect that specific economic, social, or other considerations make infeasible the mitigation measures or project alternatives identified in the environmental impact report.);

e.
The design of the subdivision or the type of improvements will not cause serious public health problems; and

f.
The design of the subdivision or the type of improvements will not conflict with easements, acquired by the public at large, for access through or use of property within the proposed subdivision.

The city council may modify or delete a condition of approval recommended in the department’s report, except a condition required by city code. The city council may add additional requirements as a condition of its approval. (GC §66474.10)

The city council may require that the subdivider defend, indemnify, and hold harmless the city, its agents, officers, and employees from any claim, action or proceedings against the city to attack the approval of a subdivision under Government Code Section 66474.9.

30 D. Denial. The city council may deny approval of the tentative map on any of the grounds provided by the Subdivision Map Act or this code. The city council shall deny approval of the tentative map if it makes any of the following findings: (GC §§66473, 66474, 66474.01, 66474.4, 66474.6)

The proposed map is inconsistent with the general plan or any applicable specific plan, any policy or guideline implementing the general plan (including the city’s design guidelines), the criteria in the Subdivision Manual or other applicable provisions of this code;

The site is not physically suitable for the type of development;

The site is not physically suitable for the proposed density of development;

The design of the subdivision or the proposed improvements is likely to cause substantial environmental damage or substantially and avoidably injure fish or wildlife or their habitat;

The design of the subdivision or the type of improvements is likely to cause serious public health problems; or

The design of the subdivision or the type of improvements will conflict with easements, acquired by the public at large, for access through or use of property within the proposed subdivision.

E.
Standards in Effect. In determining whether to approve or disapprove a tentative map application, the city shall apply only those ordinances, policies, and standards in effect at the time the application was accepted as complete. The city may apply ordinances, policies, and standards adopted later if (1) the subdivider applicant requests changes in connection with the same development project, and they are approved, or (2) if the city had formally initiated proceedings to amend the general or specific plan, Piedmont Zoning Code or subdivision ordinance and published notice of the proposed change before the application was accepted as complete. (GC §66474.2)

F.
Appeal. Any person may appeal a decision of the planning commission under Piedmont Municipal Code section 19.24.

G.
Form of Approved Tentative Map. Within 90 days after approval of the tentative map, the subdivider shall submit a revised map to the department which conforms to any changes required by the conditions of approval.

Exceptions & meaning →

SEC. 19.34 EXPIRATION OF TENTATIVE MAP.

31 A.
Expiration. The approval or conditional approval of a tentative map expires 24 months after its approval. The expiration of the map terminates all proceedings, and no final or parcel map may be filed without first processing a new tentative map. (GC Sections 66452.6(a), (d), 66463.5)

B.
Statutory Extensions.

$178,000 or More of Public Improvements. If the subdivider is subject to a requirement of $178,000 or more to construct, improve or finance public improvements outside the tentative map boundaries (excluding public right- of-way improvements which abut the property), each filing of a phased final map extends the expiration of the tentative map by 36 months, not to exceed a total of 10 years. The amount shall be adjusted for inflation each year after 2005 as provided in Government Code Section 66452.6(a).

Development Moratorium. The 24-month period of time specified in subsection A of this section shall not include any period of time during which a development moratorium, defined by state of California Subdivision Map Act Section 66452.6(f), is in existence up to five years. (GC §66452.6(b), (f))

C.
Discretionary Extensions.

General. Upon application of the subdivider submitted before the tentative map expires, the city council may approve an extension of the tentative map for a period or periods not to exceed a total of three years. No public hearing is required. (GC §66452.6(e)) Ord. 681 N.S. 9/2/08

Pending Litigation. If a lawsuit involving the approval of the tentative map is pending, the city council may, upon request, stay the approval period of the map for up to five years. (GC §66452.6(c))

D.
Improvement Plans Review. A tentative subdivision map remains valid during the period that the review of subdivision map and improvement plans by the city is underway, and the subdivider is actively pursuing approval of a final map. However, under no circumstances will the map remain valid for a period beyond 12 months after the expiration date of the tentative map. In addition, if the city engineer determines at any time during the improvement review period that the subdivider is not actively pursuing the approval of the final map, as evidenced by subdivider’s failure to adhere to time deadlines as set forth in guidelines promulgated by the city engineer, the privileges granted by this section will end and the map will expire, provided the expiration date of the tentative map has passed. (GC §66452.6(d))

32

Exceptions & meaning →

SEC. 19.35 AMENDMENTS TO AN APPROVED TENTATIVE MAP.

A.
Minor Amendments. The planning commission may approve minor amendments to the approved or conditionally approved tentative map or conditions of approval if:

The changes are consistent with the intent and spirit of the original tentative map approval;

No feature, facility, or amenity is deleted which substantially affects the project’s quality, safety, or function;

Changes in plans do not reduce natural areas, create new visible retaining or drainage structures, or substantially change pad elevations;

Changes in the design do not eliminate or add more units or lots; and

There are no resulting violations of this code.

Each amendment shall be indicated on the approved or conditionally approved tentative map and certified by the department. Minor amendments under this subsection may include minor amendments relating to exterior elevations, landscaping, interior floor plans with no exterior changes, or site circulation plans.

B.
Other Amendments. Amendments to the tentative map or conditions of approval which, in the opinion of the department, are not minor, or do not meet the criteria in subsection A of this section, shall be presented to the city council for its consideration and decision at a noticed public hearing. Processing shall be in accordance with the provisions for processing a tentative map as set forth in this article. An approved amendment does not by itself alter the expiration date of the tentative map.

Exceptions & meaning →

SEC. 19.36 VESTING TENTATIVE MAPS.

A.
General. Whenever a tentative map is required, a vesting tentative map may be filed instead. The words “vesting tentative map” must be printed conspicuously on each page of the map. (GC §§66452, 66498.1 – 66498.9)

B.
Procedures and Requirements. Except as otherwise provided in this section, the procedures and requirements for a tentative map and subdivisions generally apply to a vesting tentative map. The subdivider shall submit additional information at the time of filing the tentative map as set forth in Piedmont Municipal Code section 19.30(K).

C.
Development Rights.

33 1.
Development Rights Created.

a.
The approval of a vesting tentative map confers a vested right to proceed with development in substantial compliance with the city’s ordinances, policies and standards in effect at the date the city determines the application is complete. If, before the application is complete, the city had formally initiated proceedings to amend an ordinance, policy or standard, the city may apply the ordinance, policy or standard in its amended form if the amendment is in effect on the date the city approved the tentative map. (GC §§66498.1(a), 66474.2(b))

b.
The approval of a vesting tentative map does not confer a right to proceed with development (including the specific number or configuration of lots) if the development cannot be constructed in conformance with the applicable ordinances, policies and standard

Duration of Development Rights. The right to proceed with development as set forth in subsection (C)(1) of this section continues for one year following the recordation of the final map or parcel map. If a project covered by a single vesting tentative map is divided into phases and more than one final map is recorded, the one-year period begins for each phase when the final map for that phase is recorded. (GC §66498.5(b))

Expiration of Development Rights. The right to proceed with development as set forth in subsection (C)(1) of this section expires if a final map or parcel map is not approved before the vesting tentative map expires under Piedmont Municipal Code section 19.34. (GC §§66498.1(d), 66463.5(g))

If the subdivider submits a complete application for a building permit during the one-year period specified in subsection (C)(2) of this section, the right to proceed with development continues until the building permit expires. (GC §66948.5(d))

If a final map or parcel map is recorded based upon a vesting tentative map, and the development rights expire, the final map remains in effect without the development rights.

Extension of Time for Exercise of Development Rights. If the city does not complete processing of an application for a grading permit or for design or architectural review within 30 days of the date the application is complete, the one-year period specified in subsection (C)(2) of this section is automatically extended by the time exceeding the 30-day period used by the city to complete processing. (GC §66498.5(c))

34 Before the expiration of the one year specified in subsection (C)(2) of this section a subdivider may apply to the planning commission for a one-year extension. (GC §66463.5(g))

D.
City’s Right to Condition or Deny Approval.

This Article does not:

a.
Enlarge or diminish the types of conditions which the city may impose on a development; or

b.
Diminish or alter the city’s power to protect against a condition dangerous to the public health or safety. (GC §66498.6)

The city may condition or deny a permit, approval, extension, or entitlement relating to a vesting tentative map if it determines that either:

a.
The failure to do so would place the residents of the subdivision or the community in a condition dangerous to their health or safety; or

b.
The condition or denial is required to comply with state or federal law. (GC §66498.1 (c))
