A detailed hydraulic analysis of Idle Hour Wash for the purpose of preparing a Letter of Map Revision.
The objectives of this report are to document the on-site and off-site hydrologic and hydraulic assessment of the site and its characteristics, quantifying existing conditions peak discharges, and define the limits of 100-year on-site floodplains.
An update of the City of Yuma's infrastructure improvements plan for its parks and recreation, fire, police, general government, and streets facilities. The update is needed to comply with changes in Arizona Revised Statutes regarding the development (impact) fees that municipalities can assess.
Wilson & Company recently completed the City of Casa Grande Small Area Transportation Study. The SATS notes that “as the City of Casa Grande increases in size and planning area, the roadway network is also growing to meet the additional travel demands significant improvement measures are needed to meet the travel demand generated by forecast population and employment growth”. Given the findings of the SATS, the City of Casa Grande contracted with TischlerBise to calculate an infrastructure improvement plans and updated development fees for transportation.
The City of Casa Grande engaged TischlerBise to update its Infrastructure Improvements Plans and development fees for several categories of necessary public services. TischlerBise previously calculated development fees for the City in 1999, 2003, 2006, and 2008. Municipalities in Arizona may assess development fees to offset infrastructure costs to a municipality associated with providing necessary public services to a development. The development fees must be based on an Infrastructure Improvements Plan. Development fees cannot be used for, among other things: projects not included in the Infrastructure Improvements Plan, projects related to existing development, or costs related to operations and maintenance.
This report is being submitted for the purpose of reducing the erosion setback limits. The information contained herein supports the claim that a safe reduction in the setback distance can occur.
Millstone Manor #6 is a subdivision that was recorded in the mid-1950's. All records indicate no engineering took place with regards to potential for drainage improvements. This report will address what the natural floodprone areas are and will recommend how future permits should be processed.
This report describes the hydrologic and hydraulic analysis. Development in the lower end of the watershed has occurred without knowledge of the floodplain's characteristics.
This parcel has some houses already constructed, but most of the area is left undeveloped and can be classified as desert foothills. The objective of this report is to determine all of the flows generated by a 100-year storm in excess of 100 cfs and then map the flood-prone boundaries for the associated channels.
Offsite drainage impacts the project site from several watersheds whose headwaters lie to the northeast of the project site. This report will address the manner in which the existing offsite and the post-development onsite drainage will be conveyed across this project.
