Princeton/Somerset Storm Drainage Improvement Project
|
|
A Public Meeting has been scheduled to present the Planning Phase preferred design concept to the neighborhood and to receive your comments and opinions for Thursday, May 24th at 6:30pm at the Mahlon Adams Pavilion in Freedom Park.
HDR and City Storm Water Project Team have been evaluating several design concepts, taking into consideration hydraulic sensibility, impacts to the neighborhood, and costs associated with each alternative. We would like to receive your input on the proposal.
Project Summary
Charlotte-Mecklenburg Storm Water Services (CMSWS) has identified this neighborhood for possible storm water system improvements to address structure and street flooding. The Princeton-Somerset Storm Drainage Improvement Project lies within a drainage basin of approximately 30 acres. The project is roughly bounded by Lilac Road and Princeton Avenue on the north and south, respectively, and by Freedom Park and Somerset Drive on the east and west, respectively.
Questionnaires were mailed to residents requesting any information to identify problems with culverts, channels, and structural or street flooding in the neighborhood. This information, along with 311 service request calls, field reviews, and engineering modeling and analysis, is utilized during the planning and design phases to provide solutions to current drainage issues.
CMSWS project team will manage the Princeton-Somerset Storm Drainage Improvement Project through the phases listed below. A general description and range of typical timeframes for project phases are given. Specific work is conducted during each phase while an emphasis is placed on public involvement throughout the entire project. |

Planning Phase (June 2011 – First quarter of 2013)
As a result of citizen generated service requests, CMSWS Maintenance Team investigated the project area. A preliminary analysis of the existing stormdrainage system was completed in 2007, which revealed the need for improvements. These efforts of the Maintenance Team continued until 2009. However, due to limited resources, the project was put on hold. In 2010, CMSWS determined the project needed to be elevated to a Minor Capitol Improvement Project for the Engineering Team to implement and is now able to allow for an evaluation of more comprehensive issues in the entire project area and not just along the primary conveyance system.
Engineering consultant HDR Engineering, Inc. has completed the Existing Conditions analysis, a City Design Standard analysis, and explored several Alternative design concepts. A public meeting has been scheduled for Thursday May 24 at 6:30pm at the Mahlon Adams Pavilion in Freedom Park to present the preferred solution. A final design decision will be made based on the input offered at the Public Meeting. This will conclude the Planning Phase of the project and launch the Design Phase. The Planning Phase of a project typically lasts 12 -27 months.
Design Phase (To Be Determined)
During the Design phase, construction drawings for the alternate selected during the planning phase are developed. Many details must be addressed including the determination of specific pipe sizes and alignments, channel widths and lining types, inlet sizes and locations, utility relocations, and easement locations. Personnel from City of Charlotte, the engineering consultant, land surveyors, wetland specialists, and geotechnical engineers will be working in the area collecting information necessary to complete the design. The design phase typically lasts 21-34 months.
Permitting Phase (To Be Determined)
During the permitting phase, the required water quality permits are obtained from Federal and State governments. Other permits such as permission to work within NCDOT and Charlotte Mecklenburg Utility rights-of-way will be obtained during this phase. The permitting phase of a project typically last 3 to 9 months but may overlap other phases.
Property Easement/Acquisition (To Be Determined)
The City’s Real Estate staff works with citizens and businesses to acquire Storm Drainage Easements (SDEs) and Temporary Construction Easements (TCEs). The City requests that SDEs and TCEs be donated to provide access to your property to make the recommended improvements and provide future maintenance. The Easement Acquisition phase typically lasts 8 to 12 months and must be completed before entering the Bid phase.
Bid Phase (To Be Determined)
During the bid phase, the final plans will be circulated to qualified contractors for a competitive bidding process. By state law, the lowest responsible bidder is awarded the construction contract. The bid phase of a project typically lasts 4 to 5 months.
Construction Phase (To Be Determined)
Throughout construction, efforts will be made to minimize disruption to nearby property owners. Construction of proposed improvements will be supervised by a City Inspector. Notifications of key construction dates and will be mailed to residents prior to construction. Because projects vary in size, the typical construction phase of a project can last from 3 months to over 2 years.
