4. Location: Goodpasture Island Rd. and Valley River Drive <br /> Nature of Problem: Two bubbler catch basins ( #62367 and 62444) discharge the <br /> parking lot drainage from the Executive Parkway Suites onto Goodpasture Island <br /> Road, south of Valley River Drive. From this point there is no positive drainage <br /> or a nearby public structure. As a result, large puddles occur in the driving lane of <br /> Goodpasture Island Road during heavy rainfall events, creating the need to set out <br /> "high water" signs. <br /> Recommended Solution: By means of a permit of entry, easement, or maintenance <br /> agreement with Valley River Center, construct a system which connects the <br /> bubblers to the existing private system; or tie the bubblers into the public system <br /> to the north at the intersection with Valley River Drive . Include any additional <br /> structures necessary to correct the problem. <br /> Status: New Project 3/97 <br /> Status `98: On hold. <br /> 5. Location: Garfield St. to Cleveland St. drainage connection <br /> Nature of Problem: Recently constructed drainage system originating on Morning <br /> View Lp. above Garfield St. cul -de -sac outlets to a natural creek bed behind <br /> property at 2525 Garfield St. ( #66017). This creek flows across the undeveloped <br /> right -of -way of W 25th Ave. and through several developed residential lots that <br /> have incorporated it as an integral part of their landscaping. The creek finally <br /> inlets back to the piped system near the intersection of Cleveland St. and W 24th <br /> Ave. at ( #52575). During heavy storms, additional flow introduced to the creek <br /> from this upstream development causes erosion to the creek banks along the <br /> developed residential lots. Property owners along Cleveland St. near the inlet at W <br /> 24th Ave. are concerned that continued upstream development, especially any <br /> improvement of W 25th Ave. and the associated residential construction, will <br /> further overload the creek's capacity and wash out what is an important amenity <br /> to their property. <br /> Recommended Solution: Conduct flow analysis of existing 10" piped system along <br /> Cleveland St. south of W 24th Ave. that roughly parallels the creek to determine <br /> capacity for additional flow. Determine the feasibility of connecting any new <br /> storm facilities associated with future improvement of W 25th Ave. to the Cleve- <br /> land St. system in order to bypass the section of creek that runs through the <br /> residential lots. This may require upsizing the existing 10" pipe system along <br /> Cleveland St. between W 25th and W 24th Ayes. up to the next existing manhole <br /> north of 24th. Property owners have already reported this system to surcharge <br /> through the manholes during heavy storms. From the existing manhole north of <br /> 24th Ave. a pipe (possibly 24 ") should be installed continuing north up Cleveland <br /> St. where no pipe currently exists to the next existing manhole at 22nd Ave. <br /> 3 <br /> 97m si, 1 1197 bile <br />
