• Both entities have health and safety, contractual and site-specific requirements that had to be met
• Work with both entities to ensure that an overall successful game plan and resolution were accomplished
• 5-week delay to work schedule start due to site access agreements between the 2 entities and compacted schedule to complete

• Repaired existing berm walls and regraded 3,500-cubic yards of material within the subject area into one shared drainage swale
• Installed three rip-rap armored drainage discharge points into the new swale utilizing 200-tons of rip rap underlain by geotextile
• Completion of 3-acres of disturbed area fine graded and sloped tracked to ensure grass seed was properly administered via hydroseed
• Project completed within the extremely compressed time scheduled as originally requested
