Cobur~ 4J/E~WEB. This 35 acre site (17-03-16-22, TL 101 and 102) is currently mostly undeveloped (TL 101 is an EWEB substation site) and has a 60' wide R/W stub to Coburg Road and the full build-out of the Crescent Village PUD to tHe south will extend Shadow View Drive up to the southerly- bouridary of TL 102: ;Ttie site is bordered to the east by an undeveloped City park, to the southeast by a future phase of the C`r,'escent Village mixed use development, on the southwest by the unincorporated (outside City Limits) Kinriey Loop low derisity (single family homes on 0.21 to 1.37 acre lots) residential area, and to the west by; a'platted but undeveloped Northern Territories subdivision (which is having some difficulty providing wastewater service to the development). It appears that feasibte gravity wastewater to the site would require about 1,850 feet of off-site pipe extension at an estimated cost of $100,000 The site is, not annexed to the City with underlying AG - Agricultural zoning on TL 102 and R-1 - Low density residential on TL 101 (all.designated on the Metro Plan for R-1 low density residential). Sales of comparable land in this area have ranged from $20-$25 per square foot. This parcel is not within a flood zone and site preparation would not require additional fill to meet bfe requirements. Assuming that buildout could utilize 80% of the 35 acres (20% reduction for streets and rights-of-way), 28 acres divided into 6,000 square foot lots would yield 203 lots at a density of 7.25 units per acre (about half of maximum per Table 9.2750. This level of LDR development would generate approximately 1,945 daily trips, 150 during the AM and 205 during the PM peak hourly periods. The Transportation Impact Analysis (TIA) previously performed evaluated a 423,000 square foot Hospital and 100,000 Medical Office Building, which using the Kittelson equation for a co-located Hospital and MOB projected about 11,000 daily trips with 780 during the AM and 855 during the PM peak hours. The impacts of a potential increase of about 630 AM and 650 PM trips would need to be evaluated against the capacity and operational aspects of roadways adjacent to or downstream of the site, with trips distributed across available routes. Using a distribution pattern similar to that evaluated for the Delta Ridge site (zip code based), we could anticipate 55% to 60% of the trips using Coburg Road north of Beltline, with 30-35% to and from Coburg Road to the south. There would also be demand to and from the east that could be better served via North Game Farm Road and Crescent Avenue once Shadow View Road is fully extended. A minor amount of demand would utilize Coburg Road to and from the north and Crescent Avenue to and from the west. Page ], of 4
