Please Fix This Flawed Project with Its Many Adverse Impacts
  • Flooding
  • Subsidence
  • Liquefaction
  • Traffic
  • Access via Greenleaf
2
Flooding Issues
3
Drainage Failures Will Flood Kenilworth Tract
  • Parkside will sit at significantly higher elevation than adjacent Kenilworth tract
  • Flooding will compound for the Kenilworth homes and surroundings if any component of the Parkside drainage system fails (I.e. power failure of pumps, clogged catch basin, etc.), or in certain storm conditions
  • EIR states the tracts to the north, south, and east do NOT come out of the flood plain
4
Subsidence Issues
5
Kenilworth Subsidence Zone:
Soil and Water Testing Omitted
6
Patios are cracking
7
Walls are splitting
8
Walls are tilting
9
Walls are sinking…
10
…by as much as 12 inches!
11
Subsidence:  Result of  Overexcavation, Dewatering, & ReCompaction
  • Shea insists these techniques are time-tested and won’t harm adjacent homes
  • HB has history of residential subsidence problems
  • Shea promises careful monitoring, but the first signs of trouble may be cracked foundations on Kenilworth homes
  • Shea and/or HB will be held liable for any problems during construction or thereafter
  • If they’re so certain of their mitigation measures  they should provide indemnification for any and all casualty loss to existing homeowners
12
Liquefaction Issues
13
Liquefaction:  New Threat Caused by Mitigation in Final EIR
  • Liquefaction can occur on any wet, uncompacted sub-strata during a temblor
  • Parkside plans propose a 50’-wide Paseo Park to mitigate vibration and likely subsidence problems
    • sloped toward 22 existing homes on Kenilworth
    • they claim that ‘neither dewatering nor remedial grading will be required…’
    • made of thousands of cubic yards of fill
14
Liquefaction:  New Threat Caused by Mitigation in Final EIR
  • The wet, uncompacted sub-strata together with the new fill would be subject to liquefaction, therefore the whole slope would be at extreme risk for liquefaction and slumping during a temblor, endangering homes on Kenilworth
  • The Final EIR doesn’t account for this newly created and foreseeable problem which is a likely consequence of their proposed mitigation


15
Traffic Issues
16
Fix the Traffic Problem Now
  • Single point-of-access for 171 new homes with an additional 400 cars dumping out onto a busy street is simply bad planning.
  • Since mitigation is possible, please require the developer to provide what will be needed now so we don’t have to fix it later
17
Permanently Prohibit Opening Greenleaf Lane to Through Traffic!!
  • Connection to Greenleaf proposed as “emergency only” access
  • As currently stated a future City Council could open full access despite 100% Greenleaf and neighborhood resident opposition
  • Connection to Bolsa Chica St would remove the Greenleaf temptation and provide suitable emergency access
18
The Traffic Light Won’t Solve  Turn Trouble at Kenilworth
  • When the light is green we can’t get out because traffic is flowing down Graham
  • When light’s red cars are coming out from Parkside, so we still won’t be able to get out
  • Backups will be caused by the Parkside signal and create left turn delays when exiting Kenilworth northbound on Graham
  • Southbound cars waiting at the signal will cause dangerous visibility problems
  • “Keep Intersection Clear” striping won’t solve the visibility problem
19
Conditions of Approval
20
Condition Approval
  • Permanently prohibit Greenleaf Ln. from being opened to through traffic (allow emergency access only)
  • Require the addition of a second access point (ingress/egress) at the end of the property opposite to the currently proposed single access on Graham St.


21
Conditions of Approval
  • Indemnify (through set-asides or insurance bonds) the tract of homes to the immediate north of the property against any subsidence damage during construction and for a reasonable period of time (to encompass at least two El Nino weather cycles and a couple of temblors) after construction is completed.
  •  Indemnify existing homes in the surrounding tracts against flood damage and/or damage due to liquefaction of the added fill in the Parkside tract.
