3.0 ACTIVITIES WITHIN PLAN AREAAs indicated above, Riverside County approved the largest number of permits (3,552), which isto be expected, given its geographic area of 988,000 acres within the 1.26-million-acre PlanArea. Within the 270,000 acres of city land, 2,157 permits were issued. The data also indicatethat the majority of the development approved by Permittees in 2005 was outside of the CriteriaArea.When reviewing this data, it should be noted that the number of building/grading permits issuedwithin a jurisdiction does not have a bearing on the actual amount of land developed. The ratioof permits to acres developed in the Cities of Beaumont and Calimesa illustrate this point.Beaumont issued 67 permits, which resulted in 466 acres of developed land. Calimesa issuednearly double the amount of permits (121), which equated to a similar amount of developed land(423 acres) as in Beaumont. Finally, although these projects necessitated building permits,because building permits are not discretionary actions, MSHCP consistency was not likelyconducted for these projects. A comparison of permit issuance with JPR activity cannot bemade.3.2 Single-Family/Mobile Home Activity3.2.1 BackgroundIn accordance with existing land use regulations, development of a single, single-family home ormobile home on an existing legal parcel is a Covered Activity within the Criteria Area. Singlefamilyhome grading/site preparation permits or mobile home site preparation permits onexisting legal lots within the Criteria Area are reviewed against the MSHCP conservation criteriasolely to determine the least sensitive portion of the lot for building pad location. Theseactivities are covered by the ERP of the Property Owner Initiated Habitat Evaluation andAcquisitions Negotiation Process. Section 7.3.2 of the MSHCP lists several assumptionsregarding the predicted annual level of single-family/mobile home activity within the CriteriaArea. Based on key assumptions, the MSHCP estimated approximately 75 parcels would utilizethe ERP provision within the Criteria Area annually; these parcels were estimated to impactapproximately 675 acres of land. It was also assumed that, of these 675 acres, half (338 acres)would be within areas considered desirable for inclusion in the MSHCP Conservation Area.Finally, it was assumed that the Permittees would successfully negotiate conservation on 75% ofall of the 338 acres, leaving 85 acres for single-family/mobile home development. The annualreporting process is used to determine whether actual ERP activity is occurring in a manner thatis consistent with the assumptions made during MSHCP development.Western Riverside County MSHCP October 2006Annual Report (January 1, 2005 through December 31, 2005) 3-2
3.0 ACTIVITIES WITHIN PLAN AREAIn the first MSHCP annual report (June 22, 2004, through December 31, 2004), all single-familyhomes and mobile homes that utilized the ERP provision within the Criteria Area were reportedas losses and reflected in the rough step, Area Plan, subunit, and jurisdiction analyses. Becauseonly a small portion of the parcel was authorized for disturbance, it is likely that ERP-relatedhabitat losses were over-reported in 2004.In the spring of 2005, Riverside County modified its ERP to collect additional information andclarify, via GIS data creation, the areas approved for disturbance. This information is thereforereflected in County ERP loss data for a portion of 2005. While a vast majority of ERP activityoccurs in the unincorporated County, the RCA is working with the city planning departments todevelop a method for mapping the least sensitive portion of ERP projects for annual reportsubmittal. In cases where GIS or map information related to the least sensitive portion of aparcel was not available, the entire parcel was recorded as a loss. In summary, while theaccuracy of ERP reporting is improving, it is likely that habitat losses as a result of ERP activityare still being over-reported.3.2.2 Effect on Reserve AssemblyBetween January 1, 2005, and December 31, 2005, 317 single-family/mobile home permits wereissued within the Criteria Areas and therefore utilized the ERP provision. This number is basedon both the County’s ERP GIS file data and RCA staff’s review of County and City planningdata and files when GIS data was unavailable. These permits covered a total of 1,522 acreswithin the Criteria Area. These permits are included within loss totals reflected in Section 2.The majority of these permits are within Rough Step Units 4 and 5.3.2.3 2006 Work PlanAs indicated above, it is highly likely that ERP disturbance activity is being over-reported due tothe lack of details on the least sensitive portion of the lots (including a lack of GIS data). TheRCA will continue working with both the Cities and County to further develop and refine theERP and to improve the data collection process, specifically regarding the location of the areasapproved for disturbance. In addition, the RCA plans to acquire and review new aerial photos ofareas where previously unmapped ERP activity and projects have occurred in an attempt toretroactively refine the ERP loss database.The RCA also plans to assemble a list of parcels within the Criteria Area that have utilized theERP provision and approach the landowners regarding conservation easement incentives.
