Extracted standards
19 individual requirements pulled out of this section’s prose, each with the sentence it came from.
Density
- Density bands around buffer500 ft
Any cluster development shall decrease in intensity of use as the distance from the identified stream/water body buffer decreases, by creating imaginary five hundred (500) foot bands around the buffer.
Other
- Best management practices required
Every development shall require some form of best management practices (BMP's) to mitigate watershed impacts and limit on-site effects.
- ProhibitedProhibitedNot allowed in the district at all, short of rezoning or a variance. uses in buffer
No future development, construction or introduction of impervious surface shall be allowed in the buffer, other than road crossings, passive recreation and utilities. Uses specifically prohibited include septic systems and drainfields, feed lots, fuel or petroleum storage, sewer pump stations, etc.
- Cluster development preferred
The use of cluster development for residential uses is preferred, with required open space to be used for buffering critical watercourses.
- Exemption for commercially zoned properties
Property zoned commercial prior to March 3, 1992 shall be exempt from certain requirements if they meet DCR standards.
- Non-residential floor area per dwelling unitDwelling unitOne independent home: its own kitchen, bathroom and entrance.2,000 sqftsq ftSquare feet. An acre is 43,560 sq ft; a typical suburban lot is 7,000–10,000.
For the purpose of exchange, two thousand (2,000) square feet of non-residential floor area is equivalent to a dwelling unit.
- Environmental Impact Assessment required
Every development in the watershed shall be accompanied by an EIA that assesses the off-site impacts of stormwater generated from the proposal.
- Erosion and sediment control plan
Every development is required to file an erosion and sediment control plan in accordance with Chapter 8 of the Culpeper County Code and the Virginia E&S Control Handbook. Development that disturbs 5,000 sq ft or more shall comply.
- Golf course nutrient management plan
Golf courses shall be required to develop a nutrient management plan that demonstrates that the fertilizers and pesticides will be contained on-site.
- Lake buffer200 ft
Lake Pelham and Mountain Run Lake: Two hundred (200) foot minimum from normal pool elevation.
- Maximum disturbed area40 pct
The area of total disturbance of the land for roads/drives, utilities, structures, parking and activity space shall not exceed forty percent (40%) of the tract at any one (1) time, excluding wet ponds and BMP's.
- Maximum imperviousImpervious coverageThe share of a lot covered by anything water cannot soak through — roofs, drives, patios. surface for nonresidential25 pct
The maximum allowable impervious surface area for nonresidential development shall be twenty-five percent (25%) of the tract.
- Maximum imperviousImpervious coverageThe share of a lot covered by anything water cannot soak through — roofs, drives, patios. surface for nonresidential interior roads12.5 pct
Nonresidential subdivisions shall be subject to twelve and five-tenths percent (12.5%) maximum impervious surface for interior roads.
- Maximum imperviousImpervious coverageThe share of a lot covered by anything water cannot soak through — roofs, drives, patios. surface per residential lot15 pct
Residential subdivisions shall be limited to a maximum of fifteen percent (15%) impervious surface for each lot.
- Maximum imperviousImpervious coverageThe share of a lot covered by anything water cannot soak through — roofs, drives, patios. surface for residential subdivision tract25 pct
and twenty-five percent (25%) of the entire tract for subdivision development.
- Nonresidential development limitation
Nonresidential development other than parks, churches, and community facilities shall be limited. In PUD, nonresidential uses limited to 10% of tract.
- Primary stream bufferRiparian bufferA strip along a stream or wetland that must be left undisturbed.100 ft
Primary streams and wet ponds: One hundred (100) foot minimum from the flood way or the normal pond pool.
- Tributary buffer50 ft
Identified tributaries: Fifty (50) foot minimum from the center line of the watercourse.
- Utility services
Municipal sewer services shall be encouraged in sensitive areas. Package plants identified in section 14-20 are prohibited.
From the ordinance
Each basin contains density limits which represent a maximum for any one (1) development [i.e.: ten (10) dwelling units per acre].
