<br />Sequoia Ecological Consulting, Inc. <br />CalVTP Project-Specific Analysis and Addendum <br />Augustin Bernal Community Park Fuel Reduction <br />November 2025 <br />A-37 <br /> <br /> <br />STANDARD PROJECT REQUIREMENTS APPLICABLE? <br />(Y/N) TIMING IMPLEMENTING <br />ENTITY <br />VERIFYING/ <br />MONITORING <br />ENTITY <br />To prevent herbicides from being mobilized and soil from being compacted, which <br />increases runoff and erosion risk, the project proponent would suspend <br />mechanical and herbicide treatments if: (1) it is raining, (2) soils are saturated, <br />and/or (3) soils are wet enough to mobilize herbicides or be compacted by <br />mechanical activities. The project proponent would be prepared to completely <br />suspend mechanical and herbicide treatment activities prior to the initiation of <br />the rain event. Activities that cause mechanical soil disturbance may resume <br />when precipitation stops and soils are no longer very wet or saturated (i.e., when <br />soil and/or surface material pore spaces are filled with water to such an extent <br />that runoff is likely to occur). Indicators of very wet or saturated soil conditions <br />may include but are not limited to: (1) areas of ponded water, (2) pumping of <br />fines from the soil or road surfacing, (3) loss of bearing strength resulting in the <br />deflection of soil or road surfaces under a load, such as the creation of wheel ruts, <br />(4) spinning or churning of wheels or tracks that produces a wet slurry, (5) <br />inadequate traction without blading wet soil or surfacing materials, or (6) tire <br />track imprints or hoof marks in the soil. This SPR applies only to mechanical and <br />herbicide treatment activities and all treatment types, including treatment <br />maintenance. <br />SPR GEO-2 Limit High Ground Pressure Vehicles <br />The project proponent would limit heavy equipment that could cause soil <br />disturbance or compaction to be driven through treatment areas when soils are <br />wet and saturated to avoid compaction and/or damage to soil structure. <br />Saturated soil means that soil and/or surface material pore spaces are filled with <br />water to such an extent that runoff is likely to occur. If use of heavy equipment is <br />required in saturated areas, other measures, such as operating on organic debris, <br />using low ground pressure vehicles, or operating on frozen soils/snow-covered <br />soils, would be implemented to minimize soil compaction. Existing compacted <br />road surfaces are exempted as they are already compacted from use. This SPR <br />applies only to mechanical treatment activities and all treatment types, including <br />treatment maintenance. <br />Initial <br />Treatment: Y <br />Treatment <br />Maintenance: <br />Y <br />During The City of <br />Pleasanton <br />The City of <br />Pleasanton <br />SPR GEO-3 Stabilize Disturbed Soil Areas Initial <br />Treatment: Y During The City of <br />Pleasanton <br />The City of <br />Pleasanton
