II. Review of State Grant and What It Can
Do a. Why a Grant for this Area? -Obtained
funds based on needs of area and desire for City
services by residents b. Amount and Time Frame
of Grant Funds -Approx. 400,000 for const.
Start by June 2010 c. Review of Study Area and
Priorities -Identify priorities and base
infrastructure d. Review Work Effort by TLA
(with focus on improving public
safety) -Identify and engineer baseline
improvements

List of Immediate Priorities and Challenges

• Priorities
• Water / Fire Protection. Upgrade water system
  to improve fire flow and add hydrants
• Storm Drainage. Extend storm drainage system to
  minimize street drainage problems and flooding
• Wastewater. Extend sewer service to unserved
  area.
• Road Improvements. Improve for emergency access
• Challenges
• Funding limits what can be accomplished in
  short-term
• Road repair required with underground utilities
• Need to improve emergency access into area
  Involves discussion with adjacent neighborhoods

Upper Slide Ravine Infrastructure Study Workshop

• Results of Preliminary Engineering
• a. Existing Conditions Future Challenges
• b. Findings of Engineering Study
• c. Immediate and Future Priorities
• d. Recommended Alternative

9
Existing Sanitary Sewer Facilities

• Twelve (12) properties served by septic tank /
  leach fields in area
• Existing sewer main in Carol Drive and upper
  Doris Drive have adequate capacity to serve this
  area

10
Existing Storm Drainage Facilities

• Area has minimal underground storm drainage
  system
• Area mostly drains by surface flow north to south
  
• Centerville flume installed will serve as
  connection for future storm drainage

11
Existing Water Facilities
12
Existing Street Conditions

• Primary access route, Doris and Carol Drives via
  N. Church Street
• Approximately 2900 unpaved road surface 1300
  of paved surface
• Road widths vary between 10 to 22 feet

13
Existing Street Conditions (cont.)

Proposed Phased Infrastructure Plan

• Install new water main down Doris Drive to
  provide greater fire flow through area and add
  fire hydrants
• Install an underground storm drainage system
  along with a water quality device to alleviate
  current flooding problems and street
  deterioration in the area.
• Extend existing City sanitary sewer system to
  properties currently served by septic
  tank/leachfield systems on the southerly portion
  of the project site.
• Repair existing street system following
  installation of underground utilities.

15
Proposed Water Facilities On Site

• Installation of new water main down Doris Drive
  to provide greater fire flow through the project
  area and add fire hydrants.

16
Proposed Storm Drainage Facilities

• Installation of an underground storm drainage
  system and storm water treatment facility to
  alleviate current flooding problems and street
  deterioration.

17
Proposed Sanitary Sewer Facilities

• Extension of existing City sanitary sewer system
  to properties currently served by septic
  tank/leachfield systems in the southerly section.

18
Proposed Street Restoration

• Repair and stabilize roadway sections where
  underground utilities are to be installed.

Emergency Evacuation/Access Route

• Street system does not provide for adequate
  evacuation of residents and simultaneous access
  by emergency services
• Limited funding precludes addressing in current
  phase
• Route shown is conceptual alignment of a primary
  evacuation corridor

21

• ACCESS AND CIRCULATION
• ISSUES - HOW TO ADDRESS?
• Access into out of Study Area is a safety
  concern
• Potential to create added cut-through traffic
• Other adjacent neighborhoods will need to be
  involved
• Need to determine road widths and obtain ROW
• Not sufficient funding available to fix road
  system
• FUTURE STEPS
• Wish to separate discussion on emergency access
  options at separate workshop with other
  neighborhood
• Consultant is retained to facilitate workshop on
  alternative access options within 45 days
• Access options to be tied to infrastructure plan
  for USR
• City will pursue funding to phase in access impts

22
Upper Slide Ravine Infrastructure Study Workshop

• Questions and Comment Period
• Questions/Comments
• Next Steps
• -Finalize Infrastructure Plan
• -Present to City Council - November 2009
• -Conduct community meeting on access
• -Prepare engineering plans bid process
• -Need contract executed by June 2010
