Hydrologic Data Installation Project Overview
This project involves installing rain and stream gauges in vulnerable areas along the Upper and Middle Rappahannock River Basin to enhance emergency preparedness. Despite challenges faced due to personnel turnover and cost estimations, progress has been made towards site selections, permit acquisitions, and contractor procurement to advance the project's objectives.

Background Project Update Task Status IFLOWS Assessment Study DHS Science and Technology Project Proposal
2013 USACE report identified need for hydrologic data along the Upper and Middle Rappahannock River Basin Over 50 potential gauge sites identified, 12 determined feasible The project seeks to improve emergency preparedness by installing rain and stream gauges in vulnerable areas Cost Share between VDEM and RRBC Cost share between VDEM and RRBC GF appropriations of $42,750 to VDEM Fredericksburg, Stafford, Culpeper, Fauquier, Rappahannock each contributed $12,214 ($61,070 total)
2 sites installed: Motts Run (RG) in Spotsylvania Battle Run (RG) in Rappahannock Project lost momentum with agency personnel turnover
Considering comprehensive costs, expected project cost exceed previous estimate Negotiating firm fixed price contract We are limited to 5-6 rain/stream gauge sites Priority installation list established Sole source procurement request approved Contractor ready to perform the work

RG could be included depending on the final decided location. Rixleyville (Hazel River) RG, Culpeper Raccoon Ford RG, Culpeper Need VDEQ Approval Waterloo RG/SG, Culpeper Need VDOT Approval Recommended site Po River near Spotsylvania RG, Spotsylvania Need VDEQ Approval North Anna near Partlow RG, Spotsylvania USGS advises that this site is not suitable for a RG Need USGS Approval COMPLETE Battle Run, Rappahannock Working on permit w/ VDOT Working on permit w/ VDOT Remington RG, Fauquier Route 365 RG/SG, Rappahannock As of 18 Mar 2019
Recommended Locations Locations may be feasible but are not recommended Locations are not feasible or recommended Installations are complete As of 18 Mar 2019
VDEM commissioned IFLOWS study in Dec 2018 to assess system performance, diagnose issues and recommend improvements Preliminary findings suggest communications interference is primary cause of outages and poor data quality Final study report will be available May 2019
DHS Science & Technology (S&T) Directorate is testing inexpensive, deployable flood inundation sensors that uses cutting-edge technology S&T requested VDEM participation in the pilot program Sensors have been tested by several jurisdictions (alpha model) The Rappahannock River Installation Project area may be a suitable for pilot testing Beta model sensors will be available June 2019
DHS provides new, technologically advanced sensors at no cost to VDEM or RRBC Each sensor can monitor rain and stream levels Can use cost savings to invest in improved telemetry (cellular, satellite, iridium) DHS and manufacturer will assist in project planning, implementation and troubleshooting DHS is vested in project success Can provide a model for the upgrade of the entire IFLOWS network
Sensors are relatively untested Higher density of gauges can make O&M cost prohibitive Our contractor has no experience installing, maintaining or repairing these gauges Unknown if gauges can be upgraded to measure flow data Prolonged timeline means project will go into hurricane season 2019
