Estates Reservoir Replacement Draft Environmental Impact ReportVisual Qualitythat the Project is implemented and maintained as proposed, and that public input isincorporated into the landscape plan, the following measures are listed.Measure 3.2-2:A Landscape Plan for the Estates Reservoir Replacement Project will be preparedduring the Design Phase that will be consistent with the RHAA Concept DesignProcess and Recommendations Report 2008 (updated 2009), and ensure that areasdisturbed by construction are re-graded and planted to result in landforms that arecompatible with existing site topography and landscaping, as well as theneighborhood setting.EBMUD will coordinate with neighborhood representatives regarding theplacement of new plantings to effect screening, and this input will beincorporated into the Final Landscape Plan.The contractor shall be required to warrant landscape plantings for one yearafter project completion.Annual vegetation/tree pruning, consistent with City of Oakland FireDepartment Fire Abatement Regulations, will continue to be implemented.EBMUD will ensure that the contractor restores graded, disturbed areas to anatural-appearing landform.Site improvements will include aesthetic/architectural treatment where facilitiesare located near to, or are visible from, public trails and residences, namely:- Creating a new drainage feature with rocks and stones, around the reservoirvalve pit at the base of the excavated basin.- Improving the existing trail on EBMUD property, along Estates Drive.- Constructing a low, rustic, wooden fence along Estates Drive.- Constructing a parking area for EBMUD equipment and staff vehicles in thevalve pit.- Replacing the existing six foot high perimeter chain link fence with two inchblack webbing with an eight-foot high fence with one-inch webbing, in thesame color (black) and at the same location.Significance after Mitigation: Less than Significant.Impact 3.2-3: Effects on a scenic vista.The Project site is not within a defined scenic vista. Existing perimeter vegetation alongEstates Drive allows only filtered views into the site from adjacent residences. Mature treeson the dam downslope block distant views of the Bay. Project demolition and constructionwill occur within the bowl of the existing reservoir and will not create or open scenic vistas.Reduction of the dam embankment by 25 feet will open views to the lower site but maturetrees along the embankment slope (towards Woods Drive) will continue to block/filterdistant views of the Bay. The overall impact to scenic vistas is not considered significant.Mitigation Measure: None Required.sb09_001.doc 3-2.10 7/22/2009
Estates Reservoir Replacement Draft Environmental Impact ReportVisual QualityImpact 3.2-4: Effects on views from the surrounding area, including publicroadways, public trails, and open space and residential areas.As previously described, construction of the replacement tanks at Estates Reservoir sitewould result in a significant transformation of the visual character and site aesthetics, forpedestrians, adjacent residents, and drivers along Estates Drive. No such changes areassociated with the pumping plant improvements because no structural changes areproposed to the plant.As part of the aesthetic impact evaluation for the proposed Project, visual simulationswere produced using computer modeling and rendering techniques. As presented inFigure 2-3 the simulations illustrate the appearance of the proposed Project changes asseen from representative public viewing locations along Estates Drive. The top and sideimages are visual simulations depicting the proposed Project and the bottom images(Views 1-3) are photographic views showing the existing visual condition. Four basinviews (into the excavated bowl) are also depicted. The evaluation of potential visualimpacts associated with the proposed Project is based, in part, on a comparison of imagesportrayed in the simulations, on the proposed design and landscaping, and on anassessment of the degree of visual change that the Project would establish.All simulations of the site show views of an expansive park-like setting, with groundsurfaces planted with grasses and framed by existing trees. Views into the basin show anew drainage feature with rocks and a paved surface that contains the reservoir valve pit,and the curved retaining wall is clearly defined. The replacement eight foot high blackchain link fence is also represented. Native trees will be planted in the bowl, at random,to avoid a formal, linear pattern that does not reflect a natural landscape.As illustrated in the simulations, Project related visual changes would not substantiallyaffect existing views from the surrounding residential area because existing perimetervegetation along Estates Drive, which provides site screening will remain unchanged.Views into the site would continue to be partial/filtered and as landscaping within thebowl becomes established and matures, new plant material would create visual interestand also provide screening. Over time, the proposed landscaping would integrate thenew tanks, valve pit and re-contoured embankment slope within the overall sitelandscape. Therefore the visual impact is considered less than significant.Measure 3.2-4: Implement Measure 3.2-2, as detailed above.Significance after Mitigation: Less than Significant.Impact 3.2-5: New sources of light and glare associated with the reservoirconstruction.Project Construction - Nighttime construction beyond the normal construction workhours is not proposed but under unspecified or yet unknown conditions (emergencies)sb09_001.doc 3-2.11 7/22/2009
