WHAT IS A JLUS? 010918wsa HC BOC Page 4 •Identify and mitigate barriers to the long term sustainability of the installation’s training mission. •Promote compatibility between civilian land use and military training / operational impacts. •Strengthen coordination and communication between local governments and the installation. •Raise public awareness and understanding of compatible growth issues. JLUS PURPOSE / GOALS 010918wsa HC BOC Page 5 LAND USE COMPATIBILITY 010918wsa HC BOC Page 6 •5 mile Focus Area (around Fort Bragg) •Counties: Cumberland, Harnett, Hoke, Moore, Richmond and Scotland •Cities/Towns: Aberdeen, Eastover, Fayetteville, Hoffman, Pinebluff, Pinehurst, Raeford, Spring Lake, Southern Pines, Whispering Pines, Vass. •Partner Organizations: Fort Bragg, Fort Bragg Regional Alliance, Mid-Carolina COG, NC Department Commerce, NC DEQ, Sustainable Sandhills, The Nature Conservancy, US Fish & Wildlife Service STUDY AREA 010918wsa HC BOC Page 7 5-MILE STUDY AREA 010918wsa HC BOC Page 8 BACKGROUND RESEARCH •TASK TWO: Review & Research –Existing plans, reports, studies –Review land use policies and ordinances –Demographic information –Development trends and patterns –Environmental constraints –Climate resiliency –GIS data collection & mapping –Presentation of Research Summary –Please go to: www.rluac.com 010918wsa HC BOC Page 9 CHANGE IN DEVELOPED LAND COVER 2008-16 010918wsa HC BOC Page 10 2015 POPULATION DENSITY 010918wsa HC BOC Page 11 TASK 3: LAND USE COMPATIBILITY UPDATE 010918wsa HC BOC Page 12 FORT BRAGG RANGE & TRAINING AREAS MAP 010918wsa HC BOC Page 13 LARGE CALIBER NOISE CONTOURS CDNL / PK15 010918wsa HC BOC Page 14 OBSERVATIONS •Large Caliber CDNL Contours: –CDNLs are weighted annual measurements for low frequency noise –Day/night operations averaged over 250 days with +10 dB penalty for nighttime firing –Based on even distribution of ammunition expenditure to all artillery firing points –Off-post expansion of 57+ dB noise contour in the southeast quadrant vs. historic noise contours –Some off-post contraction of the 62-70 dB contour along southern boundary vs. historic noise contours –All 70+ dB contours remain on-post 010918wsa HC BOC Page 15 Noise Source Decibel Level (dB) Effect to the Unprotected Ear Jet take-off (at 25m)150 Eardrum rupture Chainsaw 120 Painful Live rock music 110 Average human pain threshold Motorcycle 100 Hearing damage possible after 8 hours of exposure Vacuum Cleaner 70 Annoyingly loud Quiet suburban neighborhood 50 Quiet, one-fourth as loud as 70 dB Quiet rural area 30 Quiet, one-sixteenth as loud at 70 dB 010918wsa HC BOC Page 16 010918wsa HC BOC Page 17 010918wsa HC BOC Page 18 010918wsa HC BOC Page 19 OBSERVATIONS •Large Caliber PK15 Contours: –PK15 is a single event measurement for impulsive noise that predicts complaint risk: •130+ dB = High Complaint Risk •115 –130 dB = Moderate Complaint Risk –Measurement based on adverse (noise conducive) weather conditions –representative of 85% of expected events –130+ dB contour is the primary concern due to high complaint risk for single events. –130+ dB contour is generally contained within the 62+ dB CDNL contour. –130 dB + Extends past 62+ dB CDNL in 2 locations along the southern boundary 010918wsa HC BOC Page 20 010918wsa HC BOC Page 21 LARGE CALIBER NOISE CONTOURS CDNL / PK15 COMPARISON 010918wsa HC BOC Page 22 010918wsa HC BOC Page 23 010918wsa HC BOC Page 24 SMALL ARMS NOISE CONTOURS 010918wsa HC BOC Page 25 OBSERVATIONS •Small Arms Noise Contours: –Unweighted event based measurement –Significant changes in extent of small arms noise contours compared to previous data –previously much smaller / all on- post. –Possibly due to changes in measurement of noise levels. –Small arms noise zones extend off-post a short distance along the southeastern boundary. BUT –contained within the large caliber 62+ dB CDNL. –Contours associated with ranges in the western part of the installation extend off-post. Not within any other noise zone. 010918wsa HC BOC Page 26 010918wsa HC BOC Page 27 010918wsa HC BOC Page 28 AVIATION NOISE CONTOURS 010918wsa HC BOC Page 29 OBSERVATIONS •Aircraft Noise Contours: –“A” weighted (high frequency) noise contours based on average daily flight operations with +10 decibel penalty for night operations –New Simmons AAF noise contours are contained entirely on-post. –Previous Simmons AAF 65+ dB contour extended off-post. –Noise contours now available for Mackall AAF. –Mackall AAF 65+ dB noise contours extend a short distance off-post to the north, south and west. –Pope AAF 65+ dB contour extends a shorter distance off-post than the previous contour. –Pope AAF noise levels above 70 dB contained almost entirely on-post now. 010918wsa HC BOC Page 30 010918wsa HC BOC Page 31 010918wsa HC BOC Page 32 010918wsa HC BOC Page 33 AIRCRAFT ACCIDENT POTENTIAL 010918wsa HC BOC Page 34 010918wsa HC BOC Page 35 •TASK FOUR & FIVE –Prepare Recommendations & Draft Study –Prepare Implementation Plan –Public Review of Draft –Final Draft Prepared –Final Presentation July/August 2018 JLUS PROCESS 010918wsa HC BOC Page 36 CONTACT INFORMATION Jim Dougherty, Executive Director Regional Land Use Advisory Commission 910-583-1233 director@rluac.com www.rluac.com/jlus 010918wsa HC BOC Page 37 •Benchmark Planning –Overall Project Management –Land Use Compatibility Analysis –Public Outreach –Local Government Policy –Regional Coordination •White & Smith –Land Use Policy –Implementation Strategies •Marstel-Day –Environmental, Noise & Energy –Climate Resiliency, Policy Analysis CONSULTING TEAM 010918wsa HC BOC Page 38 FORT BRAGG JOINT LAND USE STUDY HARNETT COUNTY UPDATE JANUARY 9, 2018 010918wsa HC BOC Page 39 010918wsa HC BOC Page 40 010918wsa HC BOC Page 41 010918wsa HC BOC Page 42 010918wsa HC BOC Page 43 010918wsa HC BOC Page 44 010918wsa HC BOC Page 45 010918wsa HC BOC Page 46 010918wsa HC BOC Page 47 010918wsa HC BOC Page 48 010918wsa HC BOC Page 49 010918wsa HC BOC Page 50
