Mound Groundwater BasinMound Groundwater Basin• Much of the basin lies within the boundaries of

the City of Venturathe City of Ventura• Has been an important source of water supply

f b h i l l d i i l ifor both agricultural and municipal users since the 1920’s

• Today, approximately 60% of water extracted from the Mound Basin is for agriculture use, and remaining 40% is for municipal use

5

Mound Groundwater BasinMound Groundwater Basin• Currently designated as a “medium-priority”

basin, not subject to critical overdraftbasin, not subject to critical overdraft• Currently two municipal wells withdraw from

the basin; Mound Well #1 and Victoria Well #2the basin; Mound Well #1 and Victoria Well #2– Both are old and diminishing in capacity

• Annual municipal production for the last 10 p pyears has averaged approximately 4,000 acre-feet per year

6

Need for the Project• Replace capacity with a new well (no increase in

capacity)• Existing wells have been diminishing in capacity

due to their agesN ll d d t i Cit ’ t t• New well needed to improve City’s water system reliability and redundancy

• 2009 Preliminary Hydrology Study determined• 2009 Preliminary Hydrology Study determined Mound Basin had sufficient supplies to warrant an additional welladditional well

Project Site BackgroundProject Site Background• Project site located at the end of Inez Street

Ci d i l h d l• City-owned property, previously had a large water storage tank, that has since been d li h ddemolished

• Due to existing pipe infrastructure, the Project site was considered an ideal location to install a new well

9

Project Design SpecificsProject Design Specifics• Project involves construction of the water well,

water pump surrounding structure andwater pump, surrounding structure and ancillary equipment (transformer and radio antenna)antenna)

• Existing driveway will also be expanded and i i li d dexisting water lines upgraded

• New landscaping and fencing will also be installed onsite

California Environmental Quality Act (CEQA)California Environmental Quality Act (CEQA)• Goals of CEQA are for California’s public

agencies to:agencies to:– Identify and publicly disclose the significant

environmental effects of proposed projects; andenvironmental effects of proposed projects; and• Avoid those significant environmental effects, where

feasible; or;• Mitigate those significant environmental effects, where

feasible.

Initial Study / Mitigated Negative DeclarationInitial Study / Mitigated Negative Declaration• If a project is not exempt from CEQA, an Initial

Study is prepared to preliminarily assessStudy is prepared to preliminarily assess project impactsB d h fi di f h I i i l S d f• Based upon the findings of the Initial Study for this Project, a Mitigated Negative Declaration

dwas prepared

Initial Study / Mitigated Negative DeclarationInitial Study / Mitigated Negative Declaration• For this Project, the Initial Study/Mitigated Negative

Declaration found the following environmentalDeclaration found the following environmental factors would be potentially affected by this Project:– Air QualityAir Quality– Biologic Resources– Cultural ResourcesCultural Resources– Hydrology/Water Quality– NO SIGNIFICANT IMPACTS FOUND– NO SIGNIFICANT IMPACTS FOUND

Air Quality – Potential ImpactsAir Quality Potential Impacts• Construction activities will include scrapping

approximately 12,200 square feet of the Project siteapproximately 12,200 square feet of the Project site to remove existing vegetation and prepare the ground

• Minor trenching required for pipeline installationsMinor trenching required for pipeline installations• Although minimal, it was determined that temporary

ground-preparation could produce fugitive dust that g p p p gcould impact nearby residences/businesses

16

Air Quality – Proposed MitigationAir Quality Proposed Mitigation• Project will implement “Fugitive Dust Mitigation

Measures” recommended by the Ventura County AirMeasures recommended by the Ventura County Air Pollution Control District

• Examples include; water application, use rollExamples include; water application, use roll compaction if feasible, no clearing operations during periods of high wind, sweep adjacent streets once per day, etc.

Biological Resources – Potential ImpactsBiological Resources Potential Impacts• 5 eucalyptus trees and 1 sycamore tree will be

removed to accommodate the expanded drivewayremoved to accommodate the expanded driveway• Nesting season for migratory birds is from February

1st through August 31st (Migratory Bird Treaty Act)1 through August 31 (Migratory Bird Treaty Act)

18

Biological Resources – Proposed MitigationBiological Resources Proposed Mitigation• Ideally, tree removal will occur between September

1st through January 31st1 through January 31• However, if tree removal occurs within the nesting

season for migratory birds (February 1st – Augustseason for migratory birds (February 1 August 31st), then a qualified biologist will survey the trees to ensure no migratory birds are presentg y p

• If a nest is discovered, then removal will cease until the biologist determines there is no riskuntil the biologist determines there is no risk

19

Cultural Resources – Potential ImpactsCultural Resources Potential Impacts• Due to former water tank, site was previously

excavated to a depth of 10-5 feetexcavated to a depth of 10 5 feet• New pipelines will follow the same alignment as the

existing pipelines, leftover from the former waterexisting pipelines, leftover from the former water tank

• However, whenever excavation is involved there ,existing the potential to impact unknown archaeological or paleontological resources on the Project site

20

Cultural Resources – Proposed MitigationCultural Resources Proposed Mitigation• During excavation of the top 10-feet of soil and

excavation for the transmission pipelines, a qualifiedexcavation for the transmission pipelines, a qualified archaeologist will be present onsite to monitor construction

• If potential archaeological/paleontological resources are discovered, work will halt until further assessments are conducted to determine the significance of the findings

21

Hydrology & Water Quality – Potential ImpactsHydrology & Water Quality Potential Impacts• Once operational, to ensure the well/pump continue

to function properly, the City periodically flush theto function properly, the City periodically flush the system using a de-chlorination process

• This prevents bacteria and stagnant water buildup inThis prevents bacteria and stagnant water buildup in the well

• Once flushed, the water is discharged to the storm , gdrain

• The City will monitor chlorine levels remotely to determine when flushing is required

22

Hydrology & Water Quality – Proposed MitigationHydrology & Water Quality Proposed Mitigation• To ensure flushing does not impact the local

environment and storm drain system, a State permit y , pwill be obtained

• Prior to the first flushing event, the City will obtain a g yNational Pollutant Discharge Elimination System (NPDES) permit through the Los Angeles Regional

l l ( )Water Quality Control Board (LARWQCB)• This permit requires analytical testing to ensure

t t d d t i f f ll t t b funtreated groundwater is free of pollutants before being discharge to the storm drain 23

• New well to replace capacity (will not increaseNew well to replace capacity (will not increase water/pumping capacity)– Due to existing wells diminishing in capacity due to age– New well needed to improve City’s water systems reliability

and redundancy• No significant environmental impacts found• City Public Hearing Date = September 19th (Tuesday)

– Environmental document will be made public 10-days prior
