Lynn Road Sound wall Phase I (MI 2215) – Final Noise Study (Spring 2019) 


The final noise levels measured in 2018 and 2019 do not meet the 65dB CNEL threshold, and therefore do not meet the standards to require any noise mitigation measures. Click here for a more detailed summary letter and noise measurement survey data.

Project Description


The City completed sound measurement testing on the south side of Lynn Road near the Blackwood community to determine the necessity of a sound wall, per the requirements of the Dos Vientos Specific Plan Environmental Impact Report (EIR). Based on the requirements of the EIR, this final noise study was necessary to identify properties on Blackwood Street that are backing to Lynn Road where noise levels generated by traffic volumes at the project build-out stage may exceed 65 dB. The full occupancy of the last large tract in Dos Vientos has been completed and the development is built-out, triggering the requirement for testing.

Project Time Frame

The City’s acoustical sound consultant performed final noise level measurements along Lynn Road in Spring 2019. A final report of findings can be accessed at the link above. Property owners in the Blackwood Community have been notified via mail of the results as well.
