Project Phases

Planning June 2010 - February 2013 (Complete) Design Started Rehabilitation Approach October 2017

Easement Acquisition Typically 9 to 12 months, overlaps design Permitting Typically 3 to 9 months, overlaps design Bid Typically 7 to 8 months Construction Approximately 12 months

Design Phase

The Design phase generally consists of the following:

– Preliminary Design – Permitting – Easement Acquisition – Final Design

Reasons for Project

• Pipe sinkhole issues
• Aging infrastructure
• High on City priority ranking

Subtitle, date, client name, etc. Sinkhole at Hampton Avenue and Malvern Drive Pipe condition is typical along Hampton Ave

Subtitle, date, client name, etc. Existing pipe location at 2226 Beverly Drive

Subtitle, date, client name, etc.

Upper Section

Filling Existing 36” RCP located by home foundation Add new 18” RCP and inlets Replace pipe and add new inlets Adding a new 48” RCP Location of existing sinkhole

Breakout table #1

Lower Section

Rehabilitate existing 48-inch diameter reinforced concrete pipe Rehabilitate existing dual 48-inch diameter corrugated metal pipe Adding new access structures to existing system FEMA Floodplain from Briar Creek

Breakout table #2

Elements of the Project

• Existing Pipe Rehabilitation

– Cured-in-Place Pipe lining – Minimize impacts to neighborhood – Construct five new junction boxes over existing pipe for access – Increases pipe capacity slightly due to smoother interior

• Pipe Relocation

– Take existing pipe out of service adjacent to foundation of 2226 Beverly Drive – Add system capacity with larger pipe in street

Subtitle, date, client name, etc.

Elements of the Project

• New Pipe Construction at Church Driveway

– Intercepts flows from church property – Reduces stormwater in street

• New Curb and Pipe Construction at Malvern Road

– Curb re-aligned in corner to accommodate accessible ramp – New inlets added to accommodate new curbline – Pipe to existing inlet replaced

Tree Evaluations

City Arborist Recommendations

• Tree pruning of branches
• ver roadways
• Diseased tree removal (due

to root rot)

• Landscape Management

will do this work separately from the stormwater project

• Removed trees will not be

replaced

• No schedule for this work at

this time

Two trees with root rot to be removed at: 3021 and 2758 Hampton Avenue

Subtitle, date, client name, etc.

Typical Site Impacts

• HVAC Relocation

– Plan for temporary relocation

• Landscaping / Hardscaping

– Irrigation – Fencing – Ornamentals – Temporary pet fencing – Outbuilding / shed

• Foundation Protection

– What it is and why we would do it

Current project impacts due to the rehabilitation approach are limited to restoring grass or concrete disturbed by adjacent construction

Subtitle, date, client name, etc.

Traffic Impacts

• Lane Closures

– Continued traffic flow with single lane and flaggers

• Road Closures

– Phased closures with marked detours – CMS (school buses), Police, Fire and Medic will be aware – In areas of closures driveways may not be accessible for some properties during portions of construction – On-street parking may be necessary – Closures will be as short as possible – Sidewalks will generally be accessible

Significantly decreased by rehabilitation approach

FEMA Floodplain Impacts

100-Yr Future Floodplain Extents within Project Area

Peak flow from Hampton Ave.

• ccurs approximately seven hours

prior to the peak flow from Briar Creek

Next Step - Complete Design Phase

Permitting

• 401/404 permit (NC Dept. of Environmental Quality /

Army Corps of Engineers)

• A Regional Permit is reviewed and issued by City

staff, and this review is already complete.

• The channel and wetland impacts from this project

are very limited

• DEMLR (NC Dept. of Energy, Mineral and Land

Resources/Erosion Control)

Next Step - Complete Design Phase

Easement Acquisition

• An easement is a right to use land owned by another party

for a specific purpose.

• Easements provide Storm Water Services with permission

from property owners to come onto their property and repair drainage problems and perform on-going maintenance.

• Granting an easement does not reduce the size of your

property, but it does create some limitations on the use of the area.

Subtitle, date, client name, etc.

Storm Drainage Easement (SDE) Grants access to a specific portion of the property for the purpose

• f repairing and maintaining a storm drainage system.

Temporary Construction Easement (TCE) Are not permanent easements. They give us the right to access your property to construct this project only. Sidewalk and Utility Easement (SUE) Grants access to a specific portion of the property for the purpose

• f construction and use of sidewalk.

Permanent Utility Easement (PUE) Grants access to a specific portion of the property for the purpose

• f construction and use of above- or below-ground utilities.

• Construction plans are completed

Bid Phase

• Bid advertisement
• Bid opening – Lowest Qualified Bidder
• Recommendation for approval and City Council award
