Parcels with Stormwater BMPs is reported as a Performance Measure in the EIP Project Tracker. Indicators used for EIP reporting are summarized in an annual report and highlighted each year during the Lake Tahoe Summit.
Retrofitted with BMPs – A parcel is considered to be retrofitted with BMPs when it has been awarded a BMP certificate through the TRPA BMP Retrofit Program. Both BMP certificate and source control certificate qualify as completed under this definition.
Public Facility – Public facilities include parking lots, campground, and buildings that are on land owned by public agencies, such as CTC, state parks and the USFS-LTBMU.
Has BMP Certificate – The parcel has been awarded a certificate to prove that BMPs have been installed on the property as recommended during the site evaluation.
Has Source Control Certificate – The parcel has been awarded a certificate to prove that source controls have been installed on the property as recommended during the site evaluation.
Data can be collected and reported for each retrofitted parcel or facility any time after the certificate is awarded. All information from the year must be entered by the end of December of that year. The BMP Database contains information on the status of BMP compliance of parcels in the Tahoe Basin, and can be searched based on BMP status, parcel location, watershed and other values.
Data for this Performance Measure is not reported on a project-by-project basis. Instead, data is retrieved directly from TRPA's BMP Database. All BMP certificates in the basin should be included in the BMP Database to ensure accurate reporting of this Performance Measure.
In March 2015, the subcategories for this performance measure were expanded to be consistent with BMP retrofit reporting done by the TRPA Stormwater Management Program.
In April 2018, this Performance Measure was updated to retrieve annual BMP certification data directly from the BMP Database. Results reported here are now synchronized on a nightly basis with the official system of record for BMP certifications. See https://tahoebmp.org for additonal details.
Parcels with Stormwater BMPs is reported in the Sustainability Dashboard. Indicators in the Sustainability Dashboard focus on economic, environmental, and community health in the Lake Tahoe Region.
Retrofitting public and private parcels with best management practices (BMPs) reduces pollutant concentrations of stormwater runoff from precipitation and reduces the volume of stormwater leaving those parcels. Reduced stormwater volumes result in less demand on public stormwater treatment systems and fewer fine sediment particles and other nutrients being delivered to Lake Tahoe. When fewer nutrients are available in the waters of Lake Tahoe, less algae can grow and clarity loss is reduced.
This indicator measures the number of developed parcels in the Tahoe Basin that are retrofitted with BMPs that remove fine sediment particles and nutrients. This indicator tracks private parcels and parcels belonging to large, public landowners.
