Problem Deficiencies and Justification Clause Samples

Problem Deficiencies and Justification. ‌ Some of the issues identified within the proposed project limits are as follows: • The performance measure identified in TAMP for the mainline existing asphalt pavement is, 5.1 miles in fair condition and 0.90 miles in poor condition, see Attachment K. _____ • The 2019 Deflection Study Report (Attachment J) indicates a maximum International Roughness Index (IRI) of 220 inches/mile in the EB direction and 273 inches/mile in the WB direction. As per Highway Design Manual (HDM), the maximum allowable value of IRI that does not require special consideration for design is 170 inches/mile. • The Automated Pavement Condition Survey (APCS) data for year 2016, collected for the most recent surface distresses showed signs of alligator, longitudinal and transverse cracks throughout the project limits. • The average 80th percentile deflection measurements at various test sections along EB and WB traveled way lanes, are greater than the tolerable deflections at the surface (TDS). • Shoulder widths along SR 119 within the project limits are nonstandard. The typical shoulder width is 2’ wide, except at the new subdivisions and new developments. • Pedestrian and bicycling facilities currently exist in segments around new subdivisions/developments only. • Fixed objects such as utility poles, large and small diameter trees are within the CRZ of the highway facility. • There are numerous flooding issues reported by Caltrans Maintenance at several locations along SR 119. Within the community of Pumpkin Center there is severe flooding and standing storm water issues.
