Development Projects Impact Assessment

points of reference
Traffic Safety and Congestion getting through the nearest signalized intersections in one green cycle during rush hour conditions. Standing at each proposed new intersection location, verify visibility of approaching vehicles at the minimum, safe sight-distance formula: posted speed limit + 10 mph x 11 feet/mph. Example: 30 mph + 10 = 40 x 11 = 440 feet sight - distance. Trips generated by the project on neighborhood streets are below 2,000 vehicles per day.
Safe Streets and School Overcrowding for residential areas, can the additional students resulting from the project be accommodated without exceeding the capacity of affected schools. Sidewalks are adequate to allow students to safely walk or bike to school along the streets receiving traffic from the project.
Trees and Forests complying with tree canopy or forest conservation laws.
clustered homes maximize forest preservation
Buffering and Screening of commercial and industrial projects from the view of adjacent residential homes. If the project obstructs natural views from existing homes, then the proposed landscaping must
be sufficient to preserve views.
Property Values commercial or industrial structures to be at least 300 feet from residential homes. If the project is commercial-industrial, can trucks reach the site without travelling on residential streets.
Air Quality if the project is a gas station, it must be at least 500 feet from homes, hospitals, schools, senior centers and day care facilities. The homes must be 500 feet from a highway with traffic volumes of 50,000 or more vehicles per day.
Fire and Emergency Medical Services the project must be within a four to eight-minute response time for fire and emergency medical services. In suburban-urban areas with water pressure sufficient to meet fire suppression needs.
Recreation Areas for residential projects, a minimum of 10 acres of park or other recreation areas for every 1,000 residents is recommended. For suburban-urban residential projects, there should be a neighborhood park within a ¼ mile walking distance of the site.
Water Supply for projects served by wells, verify the likelihood that area wells fail or become contaminated. If the site is served by piped-public water, the project must not exceed the safe or sustainable yield.
Flooding all proposed structures must be outside the 100-year flood plain, with runoff managed to prevent an increase in floodwater elevations downstream of the site.
Historical-Archeological Resources if a designated historic-archeological resource is present on or near the site, the local historic society must ascertain that it is adequately protected. For buildings 50 years or older slated for demolition, the local historic society should be consulted about the need for protection.
Water a buffer of native vegetation undisturbed within 100 feet of streams, wetlands or other aquatic resources. Rooftops, streets, parking lots and other impervious surfaces drain to bio-retention, infiltration or other highly effective storm water system. Project sewage is sent to a treatment plant and the pipes carrying the sewage do not overflow. The treatment plant has met pollution discharge limits for the last 3 years; If the project will be served by onsite sewage disposal, site soils should be rated for Septic Tank Absorption Fields in accordance with USDA Web Soil Survey.

Growth Management and Land Use Planning in Your Community





Towns Cities and Counties have plans setting forth how an area should grow i.e. shopping centers, new schools, housing projects and commercial, residential, institutional or industrial development. Your Local Area Plan shows how anticipated growth is likely to affect quality of life for current and future residents as well as visitors to the community. 
A Quality of Life Growth Management Plan

What Is It public opinion surveys show that the quality of life factors people view as being most affected by poorly managed growth are: schools, traffic and various environmental resources.  Other quality of life factors potentially affected by growth include: air quality; water resources such as streams, lakes, tidal waters or wells; crime; farmland loss; flooding; historic, archaeological and cultural resources; housing affordability; jobs and a healthy economy; neighborhood street safety; open space loss; park and recreation areas; placing incompatible uses near neighborhoods; police and fire services; property value; safe places to walk and bike; scenic views; shifting cost of growth from taxpayers to developers; shopping opportunities; trees and forests; wildlife.
Quality of Life Plans preserve and enhance anticipated growth if they:
present quantifiable criteria for assessing the effect of growth on each factor affected by development;
based on criteria that show how past growth has affected each quality of life factor;
show how the effect is likely to change with anticipated growth;
propose actions that prevent a decline in quality of life and enhance existing ones, and
provide factual basis for why these actions are likely to produce the benefits claimed in the plan.
The following illustrates how the six components of a Quality of Life Growth Management Plan would play out with regard to schools.  The quantifiable value for assessing school impact is percent utilization - enrollment ÷ capacity. The planning area is served by four public schools.  First the plan would show current utilization at the four schools.  Enrollment is based on actual student count; capacity is based on established formulas such as 20 students per classroom times the number of classrooms in the school. 
Next, the plan shows how enrollment would change with the anticipated growth presented elsewhere in the plan.  Many developing areas see an annual population increase of about 1%.  The 2026 enrollment below is based upon this average increase.  Of course enrollment reflects birth rates when tend to follow peaks and valleys.  The following table shows that at the end of the ten-year period -2026 - overcrowding at the three schools will become far worse.



The Actions recommended in the plan for resolving this quality of life issue are: 1 build a new elementary school and 2 expand the middle school.  The table shows this resolves overcrowding.

A New Plan for Your Area if your current plan is about to expire or rates poorly based on the Quality of Life Growth Management system, we can assist you in carrying out the outlined steps and/or conduct a community workshop and assist you in formulating a planning strategy for your community.
