Subdivision Review Checklist Subdivision: _______________ Wyoming Conservation Districts Date Received: ____________ I. II. Proposed Subdivision Area A. Location Description – northeast ¼ of Sec. 20, T15 N, R73 W (see engineer’s report for map) B. Size Description – approximately 5 acres C. What is the proposed use of the subdivision area? – commercial lots between 1 and 1.54 acres in size Soil (See engineering report for supplemental information) A. B. C. D. E. Soil Type(s) – predominantly Quaternary-age soils and mixed alluvial and terrace deposits 1. What effect does soil type(s) have on development? – The soils are well suited to development 2. Recommendation: What can be done to improve this? – Not applicable Shrink-Swell Capacity 1. What is the potential of the soil to contract when dry and expand when wet? moderate 2. Recommendations because of the shrink-swell capacity. Not applicable due to the absence of slope. Permeability 1. What is the permeability level? Moderate 2. Recommendations based on permeability. None Suitability for septic systems 1. How does the soil affect the use of sanitary facilities or septic system? Percolation rates exceed minimum standards for septic systems, the lack of an unconfined aquifer, and great depth to the potable water source suggest that there will be no problems with septic systems. 2. Recommendations for the sanitation system. None Suitability for Dwellings/Buildings, Excavation, and Road Replacement 1 1. F. Recommendations for dwellings, buildings, excavation and road replacement. Soils are subject to moderate shrink-swell as well and frost action, therefore roads should be augmented with gravel. Erosion 1. Are there roads being built? Yes 2. Are there slopes >4%: No 3. Is there a proposed management for erosion during and after construction? no 4. Will there be monitoring of erosion and sedimentation during construction? No 5. Will there be off-road vehicle use after construction? 6. What are and what will be the landscaping practices? See Albany County landscaping regulations. No III. Water Surface Water 1. Is the proposed subdivision adjacent to, or does it contain live water? (Creek, ditch, canal, pond, river, lake, spring, etc.) No 2. Will a 35' + vegetative buffer be kept in place along all waterways? (This means no buildings, corrals, or roads etc.) Not applicable 3. Will any buildings or dwellings be within a 100 year flood plain? applicable Not 4. How will water rights and access to ditch easements be addressed? Not applicable 5. Are there any potential drainage problems? No 6. Will a properly engineered storm drain system be implemented? No 7. If crossing live water, will proper road crossings be used? Not applicable 8. Are there any other flooding or water control issues that may be important? No 9. Recommendations for surface water: Not Applicable 2 B. Groundwater (see engineering report for details) 1. What is the depth to groundwater? It is greater than 75 feet to the Chugwater aquifer. 2. Has the groundwater been tested for suitability for human consumption? Yes 3. How will the use of groundwater impact nearby users? It should not be an issue. The Chugwater aquifer is not considered potable for human use; therefore water for the development will be purchased from the South Laramie Water District. 4. Recommendations for groundwater considerations. None IV. Vegetation A. Ground Area 1. Are there any concerns with potential overgrazing? Not at the present time. 2. Are there any noxious weed or pest concerns? No 3. Are there any needs or concerns for windbreaks? (Ex. Living snow Fence) At the discretion of new land owners V. 4. Is there use of native vegetation for drought tolerance and wildlife benefits? Only naturally occurring vegetation at present 5. What is the predominant ground cover? Good cover of native grasses and forbs, including western wheat, needle and thread, prairie june grass, blue grama, rabbit bush, winter fat, and Indian rice grass 6. Are there any threatened or endangered plants in the proposed subdivision area? Not to the best of our knowledge. 7. Are there stream side buffers? 8. Is there a vegetation reclamation plan in place? 9. Is there a plan for weed control? 10. Is there an existence of prime or unique farm land? No 11. Recommendations for vegetation considerations listed above: Animals 3 Not applicable No No A. Wildlife B. 1. Is there critical range for any wildlife in the area for any time of the year? No 2. Are there migration routes through the proposed area? 3. Are there any Threatened and Endangered species or critical habitat present in the area? No 4. Are there any other concerns about wildlife? No 5. Recommendations for wildlife conservation. None No Other Animals 1. Is there any other animal of concern for the proposed subdivision area? No 2. Are there any concerns with riparian areas? Not applicable 3. Recommendations for concerns of other animals. None 1. How will dust be controlled during construction and with long-term use of new roads? During long term use roads will meet county standards for dust control by covering roads with crushed granite gravel. 1. Recommendations: See above VI. Other A. Air B. Human 1. Has open space been considered? No 2. Will a perimeter fence be installed around the proposed subdivision? No 3. Are there any other human safety issues such as ditches, abandoned mine shafts, power lines, fault zones, fire hydrants, etc. that need to be addressed? No 4. Recommendations: None 4 VII. Other Recommendations or Agencies that can help with potential problems. Due to high potential for wind erosion and weed infestation, we highly recommend reseeding any disturbed land with a native grass mix as soon as possible after excavation. We also recommend that any livestock fences be constructed in a “wildlife friendly” fashion, as recommended by the Wyoming Department of Game and Fish. VIII.
