Staff finds that adequate public facilities and services are either presently available, or can be <br />available, and can be extended to serve the proposed development, as shown on the <br />applicant's plans and consistent with the above standard. <br />A memorandum (dated December 8, 2017) was submitted by Scott Gillespie, P. E., Public <br />Works Development Review Manager, discussing the roadway conditions on Capital Drive and <br />Spring Boulevard and is incorporated herein by reference and included as Attachment F. The <br />applicant's engineer submitted a comprehensive traffic safety and street connectivity study <br />that is reviewed in this memorandum. Public Works staff determined that the applicant's <br />engineer did the following: <br />• Prepared volume and speed study calculations in addition to other geomatics <br />and operational calculations. <br />• Properly estimated trips impacts from the development site per ITE standards. <br />• Included estimated construction traffic from the development site even though <br />it is not considered best practice to do so. <br />• Analyzed intersections for safety and operations. <br />• Demonstrated that no crash reducing measures are necessary. <br />• Demonstrated that recorded traffic speeds are within acceptable percentages <br />for the posted and statutory speed <br />• Demonstrated that Capital Drive and Spring Blvd have adequate capacity to <br />serve the development site. <br />• Demonstrated that no measureable congestion from an engineering standpoint <br />will result from the proposed development. <br />The applicant's submitted traffic safety and street connectivity study found no evidence that <br />suggests the existing roadway network is unsafe or incapable of accommodating the traffic <br />impacts from the proposed development. The study indicates volumes and speed along Capital <br />Drive and Spring Boulevard were well within expected standards for local streets. Public Works <br />staff also reviewed information associated with the 2014 re-paving of Capital Drive and Spring <br />Boulevard, finding that pavement structural sections were designed to City standards and have <br />the capacity to serve the existing neighborhood and the proposed development. Also, the <br />pavement sections were found to be adequate to accommodate construction traffic from the <br />development site. <br />The review by Public Works staff also found the measured speeds on the streets are consistent <br />with the statutory and posted speeds and do not warrant an increase or reduction in the <br />posted speed. The measured speeds and lack of crash history indicate the roadway is operating <br />as intended. Research indicates that these streets have been fully improved with curb and <br />gutters since the 1950's and were designed to standards and exceptions of the design engineer <br />and City/County engineers at the time of their construction. The roadway has historically <br />performed well and there is no engineering evidence to the contrary. Public Works staff <br />concludes there is no evidence to suggest the existing roadways are unsafe or incapable of <br />serving the development site, and concurs with the applicant's engineer and recommends the <br />Capital Hill PUD (PDT 17-1) February 2018 35 <br />Page 35 <br />
