Friends of Riverside's Hills v. City of Riverside, 26 Cal. App. 5th 1137

Background

The Lofgrens sought a Planned Residential Development (PRD) permit to build six single-family homes on an ~11.6-acre Riverside parcel in the Residential Conservation (RC) Zone; city issued a CEQA negative declaration.
RC Zone distinguishes conventional subdivisions (lot minimums tied to average natural slope; 0.5 du/ac benchmark) from PRDs (minimum lot size 0.5 acre, ability to cluster, and potential 25% density bonus if certain open-space and "Superior Design" criteria met).
The Lofgrens submitted multiple tract and conventional subdivision maps with slope data; planning staff recommended approval subject to conditions (including preservation of steeper areas as open space and stewardship by a recognized conservation group).
Friends of Riverside’s Hills (FRH) challenged the approval and negative declaration, arguing the project violated RC standards (failure to cluster in less steep areas, excessive grading, lots below conventional 2-acre minimum without variances) and thus CEQA required an EIR; alternatively claimed city abused its discretion.
City revised the project from seven to six lots after FRH comments; City concluded benchmark density was met and that bonus density prerequisites were satisfied; trial court denied FRH’s writ petition and this appeal followed.

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether CEQA required an EIR because the project conflicts with RC Zone standards	FRH: Record shows conflicts (failure to cluster homes on less steep areas, excessive grading, and noncompliant lot sizes), so a fair argument exists that environmental impacts may be significant	City/Lofgrens: Record contains no evidence of code violations; conditions of approval require clustering and open-space preservation; maps and staff analyses support negative declaration	Court: No substantial evidence of code violations in the record; negative declaration upheld (no fair argument for an EIR)
Whether City abused its discretion by approving benchmark density based on average natural slope data	FRH: Slope figures vary across maps; record lacks substantial evidence that lot slopes are 15–30% (which underlies 2-acre minimums for benchmark density)	City: Revised conventional map and engineering data show all relevant lot slopes between 15–30%; the City may credit applicant's credible professional data	Court: Revised conventional map provides substantial evidence; abuse-of-discretion claim fails (deferential review to city findings)
Whether City improperly deferred selection/verification of "Superior Design" elements needed for density bonus	FRH: Selection deferred to grading/building permit stage, so city granted bonus without required assurances	City/Lofgrens: The maps listed mandatory project requirements and code does not require final design element selection at PRD approval stage; conditions require later evidence of compliance	Court: PRD applicant had identified required elements; code permits later-stage verification; no abuse of discretion
