Basics
This project sought to utilize these LiDAR data and other remotely sensed data to identify and quantify the potential to develop stormwater detention and infiltration areas based on small-scale patterns of land topography. Utilizing the high vertical accuracy and resolution inherent in the existing LiDAR data set, we have demonstrated for the first time that it is feasible to identify the hydrologic connectivity and the topographic features of the urban areas and the wildlandaurban interface (WUI) areas.

Threshold Categories
-
The input of fine sediment particles has ben identified as a major cause of clarity decline over the last 40 years, with over 70 % of those particles coming from urban areas and into stormwater.

| 08/30/2017 7:20 PM | Kiara Cuerpo-Hadsall | Objectives: This project seeks to utilize newly acquired LiDAR data and other remotely-sensed data to identify and quantify the potential to develop stormwater detention and infiltration areas based on small-scale patterns of land topography. The project: • Quantified the volume of stormwater detention available through this means. • Tested the methodology on an existing urban area in collaboration with a local agency. • Ranked the individual MSIS by volume (largest to smallest) within each basin watershed. • Worked with local jurisdictions assign a water quality weighting to each of the volume-ranked MSIS that indicate the highest influx of fine sediment particles. • Developed a methodology whereby the accumulated sediment in an MSIS can be sampled, analyzed for particle size distribution and thereby provide firm data for the assignment of TMDL credits and validation of existing crediting tools (such as the Pollutant Load Reduction Model [PLRM]). • Made available a design tool utilizing the Tahoe Environmental Research Center's existing 3-D visualization laboratory where agencies can easily view and design these MSIS in an immersive three-dimensional environment using the LiDAR data and other spatial data. |

| 08/30/2017 7:20 PM | Kiara Cuerpo-Hadsall | Findings: • The methodology has been developed and tested for two locations: Incline Village, NV, and South Lake Tahoe (CA and NV). • For Incline Village, the analysis showed that a system of 1,300 distributed detention basins could detain (and potentially infiltrate) approximately 49,000 m3 of stormwater in the urban area. Such a system would be capturing water from 56% of the urban area. • For South Lake Tahoe, the analysis showed that a system of 1,600 distributed detention basins could detain (and potentially infiltrate) approximately 1,200,000 m3 of stormwater in the urban area. Such a system would be capturing water from 42% of the urban area. • The current system of 192 detention basins in South Lake Tahoe cover an area of 218,000 m2. The addition of the full number of distributed detention basins would cover over 1,000,000 m2. |

| 08/30/2017 7:18 PM | Kiara Cuerpo-Hadsall | Management Implications: • Urban stormwater is the largest contributor to the decline of Lake Tahoe’s clarity. The area of the urban watersheds that are being treated to remove or detain fine particles could be increased by many times. Moreover, because of the small size of the proposed basins, planning and permitting time is reduced by many years, thereby reducing costs. The scale of the proposed detention basins are such that could readily be constructed in a matter of days, thereby being a very efficient way of utilizing small amounts of residual funds. • These estimates on the potential number of distributed detention basins are an upper bound. Ground truthing and comparison of existing infrastructure (e.g. hidden culverts), as well as eliminating sites with low permeability soils, would likely reduce this, as would finer scale assessment of private property and other considerations. Needless to say, even a 50% deployment of distributed detention basins would have a huge impact on stormwater capture rates. It would also do this in a way that had minimal visual impact, would require minimal planning and permitting delays, would utilize public lands fully to provide protections to the streams and the lake, and would provide seasonal wildlife habitat. |
