Traffic Impact Analysis (TIA)

Public Utilities:  

LCWSD: In early 2021, the LCWSD adopted an amendment to their development policy.  To paraphrase the amendment, LCWSD will not issue a developer a willingness and capability assurance letter if it needs to connect to downstream development’s infrastructure by another developer that has not yet received a SCDHEC permit to operate.

It is staff's understanding that this project intends to gain sewer access by connecting into the recently initiated Roselyn sewer improvements. At this time, the estimate we have received on the completion of the primary sewer line is 12-24 months.

It is important to note that Civil Construction plans will not be reviewed by the County or the District until the Roselyn sewer improvements are active (or very close). 

Natural Gas: Lancaster County Natural Gas has issued a willingness and capability letter to serve this site.

Power: Duke Energy has issued a willingness and capability letter to serve this site.

Technical Review- Major Comments:

County Engineer: 

• A Traffic Impact Analysis (TIA) was submitted to Lancaster County on 9/9/2022. We have sent it to our consultant for pricing and have not heard back as of the date of this writing. Once we have a price and the developer pays, the consultant will analyze the TIA and give us a report. An off-site improvement recommended in the final TIA once approved will need to be adhered to.
• The proposed hammerhead in the area of William Farm Lane is not entirely on property controlled by this developer. Are there agreements and/or easements in place for this?
• LCWSD will need to provide a letter certifying they have availability and capacity for water and sewer service prior to a grading permit being issued. It appears the plan is to tie into the future force main for Roselyn (Lennar). As you are aware this sewer line is under construction and will not be available for around 18 months.
• The other sewer ties in on the east side of the plan is to Shiloh Commons Sewer pump station. It appears that 117 lots are directed in toward that sewer line. The phasing of the road access points needs to be such that not more than 100 houses are built prior to the second access going in. The note provided on Sheet PL-1 General note #3- indicates this should be based on CO’s of the houses. We strongly believe this needs to be based on building permits and not CO’s. This is easier to track and eliminates the potential of a completed house sitting ready with potential owner ready to close waiting on the roadway to be built.
•  Encroachment permit through SCDOT will need to be obtained. Entrances will need to meet SCDOT requirements for sight distance and separation from other roads/drives.

 Fire Marshal

• Roadway will need to be widened to 26 feet at hydrants that are not at intersections or cul de sacs.
• A second means of ingress/ egress will be required prior to the 100th lot being created.

Planning

• Changes to this plan will likely be needed to reflect all site specific comments resulting from the TIA review.
• Confirm open spaces and park calculations are in keeping with what is shown on the plan.
• As a reminder all easements must be located within open spaces or the non-buildable areas of a lot (setback areas),you may want to contact LCWSD about where you plan to located your lines (water and sewer) at least preliminarily as you may lose lots at the civil phase otherwise.
• Please submit recorded easement agreement for the portion of a turn around and road which will not be within the property lines of the land which you control. Also any supplementary easements which are necessary to create or expand the ingress/ egress locations shown will need to be submitted.
• Stubs and sidewalks should be shown fully extending to the property line and a note should be added acknowledging that these locations are intended to serve as connections to future developments.

Staff recommends Approval subject to the following conditions:

1. Address outstanding TRC/Evolve comments within 60 days of Planning Commission approval.
2.  Address outstanding TIA comments within 90 days of Planning Commission approval.
3.  Final County Council approval of the associated rezoning (RZ-2022-0733).
