This project responded to Lake Tahoe Basin stakeholders’ identified needs to review and potentially update the current stream environment zone (SEZ) policy to ensure implementing ordinances and program elements are consistent with best available science and data, and support desired SEZ conditions, functions, processes and values.

Threshold Categories
-
The stream environment zone land designation is unique to the Lake Tahoe Basin. Stream environment zones (SEZ) are land areas that owe their physical and biological characteristics to the presence of surface water and/or shallow groundwater for a significant duration of the growing season in most years (TRPA 1977).

| 09/13/2017 3:34 PM | Kiara Cuerpo-Hadsall | Objectives: This project will be integrated with the ongoing SEZ Roadmap effort to establish a classification system of different SEZ types based on soils, hydro-geomorphology and vegetation that is protective of identified SEZ desired functions. Specific objectives were: • Review and documentation of SEZ desired conditions, functions, process and values. • Review SEZ definitions. • Review of SEZ field delineation criteria and indicators. • Review of wetland and riparian area classification schemes with an eye towards identifying which system might be most applicable to SEZ. • Map aquatic resources as a foundation to SEZ mapping. It was reasoned, based on the definition and field delineation indicators of SEZ, that aquatic resources were core to producing a basin-wide map of SEZ. • Release the aquatic resource map to an impartial third party to judge the extent to which the aquatic resource map produced for this project was consistent with current California wetland and riparian mapping standards. • Confirm the SEZ classification scheme recommended by the Field Delineation Workgroup. • Produce a basin-wide SEZ map based on proposed SEZ classification scheme and proposed indicators provided by the Field Delineation Group. |

| 09/13/2017 3:33 PM | Kiara Cuerpo-Hadsall | Findings: Perhaps the greatest value of this project was the contribution of the different individuals that participated in workgroups in combination with the project team. Each individual brought their respective technical expertise and years of institutional knowledge that combined, through many hours of discussion, have addressed several identified SEZ program update needs. Together, workgroups have forwarded a set of recommendations that very likely can be integrated into Tahoe SEZ program with some additional stakeholder, public and decision-maker review and discussion. The process followed in this project has resulted the following findings and recommendations: • A review of existing SEZ definitions were found to be adequate and indicate no need for revisions. • Desired SEZ conditions, functions, processes and values have been documented in this report and can help to focus management and regulatory actions. • Although there are no recommendations for adjusting the overarching criteria (i.e., vegetation, hydrology, geomorphology, and soils) for SEZ delineation, several updates are proposed for SEZ indicators. The Field Delineation Workgroup found that updates to soil, vegetation, aquatic habitat, and floodplain indicators would bring the SEZ program up to date with current industry standards. Similarly, current methods for evaluating proposed indicators and thus determining SEZ boundaries are suggested to improve the consistency of SEZ delineation across SEZ practitioners. • The Field Delineation Workgroup has proposed a pragmatic scheme for SEZ delineation and review that takes into account the different types and scales of project actions. Implementation of this system could lead to cost savings without a reduction in SEZ protection. *** See www.fs.fed.us/PSW/partnerships/tahoescience for additional findings. |

| 09/13/2017 3:32 PM | Kiara Cuerpo-Hadsall | Management Implications: • The map of potential SEZ produced in this project indicates that there is considerably more SEZ (29,391 acres) than has been previously reported (approximately 17,700 acres). These differences probably do not indicate an increase in SEZ area since last mapped, but are more likely a function of higher resolution base data used for this project. Higher resolution data provided the ability to more accurately map stream tributary networks and better reveal wetland and riparian associated vegetation. In addition, previous SEZ mapping efforts may have been biased toward representing the extent of SEZ in the urban context where the greatest development pressures exist in the Tahoe Basin. |
