Lake Tahoe Report #69

With summer here, public Environmental Improvement Program (EIP) projects to restore proper watershed functions and prevent lake pollution are in full swing. Eroding slopes along roads are being stabilized. Street drainage is being improved with new curb and gutter projects. What many people don’t realize is that these public projects must be matched by thousands of installations of best management practices (BMPs) on residential properties, or they won’t work. Large municipal storm-water conveyance and treatment systems are designed to handle only the water coming off public streets. All runoff from private properties must be infiltrated into the ground before reaching the public right of way.

The implementation of BMPs by homeowners is called the “private contribution” to the EIP. It is required by Tahoe Regional Planning Agency (TRPA) ordinances. It is an essential part of our community effort to prevent the lake’s further decline in clarity. Fortunately, there is a coalition of agencies that are ready to help homeowners with this task.

The Nevada Tahoe Conservation District (NTCD) is one agency assisting homeowners by offering free BMP Site Evaluations. Homeowners in Nevada can call (775) 586-7223, ext. 1, to schedule a free site visit by an agency staff member. The homeowner will receive a one-on-one consultation and a written report with recommendations on what BMPs are needed. In addition, they will get a free copy of the national award-winning book, the “Home Landscaping Guide for Lake Tahoe and Vicinity,” and a list of contractors who are trained to install the recommended BMPs. California residents seeking a free site evaluation can call the Tahoe Resource Conservation District, (530) 543-1501, ext. 6.

Most homes built during the last 10 years have had BMPs installed as part of the building permit process, as required by TRPA. If your home was built prior to 1996, it probably does not have properly designed or maintained BMPs. Chapter 25 of the TRPA Code of Ordinances describes the requirement for the “BMP retrofit” of these homes. The most important BMPs are those that reduce soil erosion by vegetating and mulching bare soil and stabilizing eroding slopes with vegetation and structural means. It is also essential to capture all water running off pavement and rooftops and to infiltrate it into the soil on the property with an infiltration system. Properties should be able to properly handle “the 20-year storm,” which dumps an inch of rainfall in one hour.

The NTCD is seeking to work with several homeowners from the same street at one time. This neighborhood approach can create efficiency by getting property owners together to help each other, and it can reduce costs if contractors can bid multiple jobs and buy materials in bulk. It is especially helpful when residents on a street that will be getting curbs and gutters band together to do the private BMPs at the same time. Todd Gillihan, the Backyard Conservation coordinator, NTCD, says this kind of systematic approach, called community watershed planning, can facilitate BMP implementation in Tahoe neighborhoods. This year, NTCD is planning to emphasize neighborhood projects in the Kingsbury Grade residential area of Douglas County.

The conservation districts work in a coalition, called Partners in Conservation, to help property owners implement BMPs through education and technical assistance. The other members of this coalition are the USDA Natural Resources Conservation Service, the TRPA, and University of Nevada Cooperative Extension.
